00:38 Triffid_Hunter RifRaf: yeah hd44780 4-bit mode uses only 6 or 7 wires
00:38 Triffid_Hunter RifRaf: beware, real HD44780
00:38 Triffid_Hunter s can't talk any faster than 1MHz or so
00:38 Triffid_Hunter some of the newer clones can, ks0066 from memory is ok
00:41 RifRaf ok its just most examples i see put the data pins on one port and the others somewhere else
00:42 RifRaf just soldered 8 wires to portd on a smt chip for an lcd and cannot change it
00:43 Triffid_Hunter yeah can use any gpio you like
00:43 Triffid_Hunter code is simpler if the 4 data wires are sequential on one port
00:44 RifRaf yep did that, thanks, now i need some code and should be able to get something on the screen
01:10 Jak_o_Shadows Just installed a bench vise.
01:14 rue_house good show!
01:14 rue_house do you have soft jaws for it?
01:15 Jak_o_Shadows Not entirely sure what you mean. The jaws are removable, and have a cross-hatched panel on them. I should make some wooden jaws for it at some point.
01:15 Jak_o_Shadows Also, it's only screwed in wtih 2/3 bolts, but that doesn't matter, as the bench is an mdf/pine job, which means it moves around a bit
01:16 rue_house mine never stays tight for more than 2 weeks
01:28 RifRaf rue_house did you have a char lcd tutorial?
01:28 RifRaf i can't get this this going
01:35 shuggans I have an ST branded Mosfet... Says "TYN 4086 MAR 531"
01:35 shuggans Cant find any info on it
01:35 shuggans Do I need to look @ something different?
01:55 rue_shop2 RifRaf, hmm
01:56 rue_shop2 I dont know if I put all the docs for it togethor even
01:56 shuggans On a mosfet... if i break a circit with it... tying one side to pin 1, one side to pin 3, I control the "gate" with pin 2 right?
01:56 rue_shop2 no
01:56 rue_shop2 gate is on the side
01:56 shuggans Then how does this work?
01:57 shuggans so pin 1, pin 2 for circuit?
01:57 rue_shop2 shuggans, hah, cant do a mosfet tutoal NOW
01:58 RifRaf got hello world in 8bit mode :)
01:59 RifRaf using this page and changing the ports http://projeneering.com/electronics_projects/elec_lcd.html
01:59 rue_shop2 hmm
01:59 rue_shop2 did you look at the servo tutorials we were working on
01:59 RifRaf not yet
02:00 RifRaf well yes, have been looking for stuff all day
02:04 shuggans Ok... So... Have Negative side of a 9v battery hooked to a small dc motor.. the the positive side to pin 3 on a mosfet, and from pin 2 on mosfet to the other motor lead. applying current to pin 1 should cause motor to turn right?
02:14 Triffid_Hunter shuggans: only if you feed it 10v more than your battery voltage
02:15 Triffid_Hunter shuggans: see http://teach.alimomeni.net/2012spring2/wp-content/uploads/2012/02/microcontroller-mosfet.jpeg and http://www.nerdkits.com/videos/motors_and_microcontrollers_101/finalcircuit.png
02:20 Jak_o_Shadows1 http://jak-o-shadows.users.sourceforge.net/random/Fetdriver.PNG is what a couple of people helped me through a little while back. This is for driving from a uC
02:20 shuggans So Drain should be the + on the battery?
02:21 shuggans Source the -?
02:21 Triffid_Hunter shuggans: no mosfet pin connects to battery +
02:22 Triffid_Hunter Jak_o_Shadows1: yikes, that'll set the mosfet on fire if you drive a decent load with it
02:22 shuggans even for just 1 way operation?
02:23 Triffid_Hunter Jak_o_Shadows1: better off using no driver and picking a suitable mosfet I think.. IRLB8743, FDP8870 and AOT240L are all excellent candidates for driving direct from uC pins, the AOT240L even works down to 3v
02:24 Triffid_Hunter shuggans: follow http://www.nerdkits.com/videos/motors_and_microcontrollers_101/finalcircuit.png . the diode is important- without that, your mosfet risks being damaged every time the motor turns off
02:24 shuggans will an LED work?
02:26 Triffid_Hunter shuggans: it'll be damaged when the mosfet turns on
02:27 Triffid_Hunter reverse breakdown on leds is generally only about 5v
02:29 shuggans Just tested it on a 9v battery... works one way, not the other, doesnt get damaged - does this mean it will work?
02:39 Triffid_Hunter shuggans: maybe for a little while. breakdown avalanche doesn't always kill them straight away
02:40 shuggans little while is all i need :P
02:40 shuggans just for learning
02:40 shuggans nee it to work once to see
02:40 Triffid_Hunter shuggans: note that they tend to fail short circuit when they do fail, so if it suddenly burns up one day, your mosfet won't be protected anymore
02:41 Triffid_Hunter generally they fail short circuit then the bonding wire that goes from stirrup to anvil inside the led melts
02:41 shuggans I see
02:42 Triffid_Hunter if you get leds with waterclear lenses, you can generally see yellowing if that's happened
02:43 shuggans I still dont understand the mofset: this is my first electronics project
02:43 shuggans So I have pin 1 2 3
02:44 shuggans and the motor circuit (with the LED in place of the normal diode)
02:44 shuggans and a 9v... how do I connect them all together?
02:45 shuggans pin 2 = - and pin 3 out to motor?
02:45 shuggans source pin or drain pin is from battery?
02:49 Triffid_Hunter shuggans: http://teach.alimomeni.net/2012spring2/wp-content/uploads/2012/02/microcontroller-mosfet.jpeg
02:49 rue_shop2 Tom_itx, your blue programmer isn't happening...
02:49 Triffid_Hunter shuggans: the middle pin is always drain. it's also connected to the tab. drain goes to the load, ie the motor -ve
02:50 rue_shop2 odd
02:50 rue_shop2 wonder if this is a futz up 6 pin on your old board
02:50 Triffid_Hunter shuggans: http://circuits.datasheetdir.com/97/TRANSYS-IRFZ44N-pinout.jpg
02:51 e_shop2 goes back to his reliable 10
03:08 shuggans ok... so the circui you showed me is wired up.
03:08 shuggans Do I need to use a sepearate powersource to turn the gate on?
03:18 RifRaf so with avrlib i can get the lcd going on one port, think i'll stick with avrlib again even if its old
03:24 Jak_o_Shadows1 oh really? Why? I thought the transistors got the voltage up to acceptable levels and then that's it?
03:24 shuggans Do you technically NEEd a drain then? My wire from drain to the battery came Disconnected + the circuit still functions....
03:32 rue_shop3 for electricity to operate it has to go around in a circle
03:34 RifRaf rue i got the lcd going with your encoder_lcd code, but have the lcd on portD so cannot use the interupts, can another input pin be used to read quad encoding?
03:37 rue_house we can move the lcd over
03:39 RifRaf no i have hardwired it to the mcu, and its surface mounted
03:39 rue_house ah
03:39 rue_house what is it you want to do then?
03:39 RifRaf you did have it on port c, but port d was unused on the pcb
03:39 RifRaf well get used to avrs for a start
03:39 rue_house interrupts?
03:40 RifRaf so been blinking and stuff today
03:40 RifRaf no i know nuthing, starting from scratch
03:40 rue_house :) get all warmed up again
03:40 RifRaf i want to make a motor driver with this board
03:41 RifRaf and have feedback from pots in the joints
03:41 RifRaf and control the position with pots for now
03:41 RifRaf then learn how to program a robot arm
03:41 rue_house ok
03:41 RifRaf to do things
03:41 rue_house !time
03:41 tobbor My watch says its 01:32AM Sun Jan 13 2013
03:42 rue_house dont know how much I can help ya right now ;)
03:42 RifRaf same, i have to go back to work in morning, but will be back at nights, just when you pass out
03:42 rue_house heh
03:42 rue_house I remmeber this problem
03:42 RifRaf but has been a productive week
03:43 rue_house good show
03:43 rue_house all the programmers work?
03:43 rue_house software all in good order?
03:43 RifRaf usbtiny is
03:43 RifRaf yep can compile avrlib and normal stuff, got it aall setup today
03:43 rue_house thats a big step
03:44 RifRaf yeah
03:45 RifRaf arduino environment good too and android
03:45 RifRaf gonna make an app :)
03:46 RifRaf maybe control stuff with bluetooth, its all learning
03:53 shuggans any reason a mosfet would ignore a gate + power through?
03:53 shuggans =bad mofset?
03:54 shuggans mosfet*
04:01 rue_house shuggans, whats the part number of the mosfet again?
04:02 rue_house shuggans, do you have a multimeter?
04:02 shuggans That other one wasnt a mosfet :P. this one is though - 45n03lta
04:02 rue_house shuggans, what are you operating with the mosfet?
04:03 shuggans motor
04:03 rue_house shuggans, do you have a multimeter?
04:03 shuggans dc motor, 2 post
04:03 shuggans not at this location :(
04:04 rue_house where did you get the mosfet from?
04:04 shuggans PSU
04:05 rue_house it has long legs?
04:05 shuggans yes
04:05 rue_house ok, when the writing is up, the legs go: gate, drain, source
04:06 rue_house the voltage from the gate to the source, controls the resistance from the drain to the source
04:06 rue_house for this fet, source is the - end, drain goes to the motor
04:06 rue_house is that what you have?
04:08 shuggans currenlty I have - motor post 1 >> + battery, -battry >> mosfet pin 2, mosfet pin 3 >> motor post 2
04:08 shuggans and an LED as i diode between the battery posts
04:08 shuggans but it is spinning up the motor without anything on the gate
04:09 rue_house you have pin 2 and 3 backwards
04:09 rue_house for fets, electrons go from - to + :)
04:10 shuggans hmmm
04:10 rue_house so the fet source goes to - and the drain goes to +
04:10 rue_house switch it around and tell me if the motor stops
04:10 rue_house how many volts is your battery?
04:10 shuggans it is still spinning when switched :(
04:10 shuggans 9 volts
04:11 rue_house ok hold up a min
04:13 rue_house ok
04:13 rue_house shuggans, do you have a resistor?
04:14 shuggans not in the circuit
04:14 rue_house no, but do you ahve any resistors?
04:14 shuggans all over this psu i dismantled :P
04:15 rue_house ok, please connect pin 1 only to a resistor that goes to pin 3
04:15 rue_house (pin 1 is the left most pin)
04:16 shuggans resistor = the the pill looking things? (im jsut learning what all this is / does)
04:16 rue_house say when ready
04:16 rue_house :)
04:16 rue_house resistors have the stripes
04:17 shuggans kk, let me unsolder one from here... :P
04:17 rue_house not one with silver or two gold stripes!
04:17 shuggans 2 red, a brown, a gold?
04:18 rue_house red red brown gold?
04:18 shuggans yes
04:18 rue_house that will be ok
04:19 rue_house do you know the electrical symbol for a resistor?
04:19 shuggans no
04:20 rue_house it kinda looks like ----/\/\/\/\---
04:20 Jak_o_Shadows1 I prefer the rectangular box, but apparently australia likes the sharp squiggly line more
04:20 rue_house the box is the europe symbol
04:20 rue_house all the rest of us use the usa synbol
04:21 shuggans lol
04:21 shuggans ok
04:21 shuggans It stopped!
04:21 rue_house ok, the fet stores power which makes it stay on
04:21 rue_house good work
04:22 rue_house to turn it on, short 2 to + of the battery
04:22 rue_house what are you making?
04:23 shuggans Just a test board to test a mosfet
04:23 shuggans I want to learn to make a serial controlled dc motor driver
04:23 rue_house ok
04:23 shuggans a pretty big one...
04:25 rue_house you have much to learn :)
04:25 shuggans shorting 2 does nothing :(
04:25 rue_house putting a wire form 2 to + of the battery should turn on the motor
04:25 rue_house haha
04:25 rue_house no, sorry
04:26 rue_house from 1 (left most) to the + of the battery
04:26 rue_house no fair! its 2am!
04:26 shuggans lol ok
04:26 shuggans yes
04:27 shuggans right most?
04:27 shuggans no ur rught
04:27 shuggans left most does it
04:27 rue_house left, should be left most (writing up) to +
04:27 rue_house want to make it reverse operation?
04:28 shuggans so...
04:28 rue_house just a sec, I have a drawing for you
04:28 shuggans I would use a +5v to turn this on from a microcontroller right?
04:28 rue_house yes, and no
04:29 rue_house to drive the gate of a fet properly, you have to give it 10V
04:29 rue_house UNLESS
04:29 rue_house its a logic level fet, in which case 5 or 6V will do
04:30 shuggans it says logic level!
04:30 shuggans on the data sheet I found: TrenchMOS transistor, Logic Level FET
04:31 rue_house oh, so it does
04:31 rue_house good pick!
04:31 shuggans On a microcontroller though, there is a way to output a set voltage right?
04:31 shuggans Im not sure how this all works... :/
04:31 rue_house binayr
04:31 rue_house 0 and 0
04:31 e_house starts a
04:31 rue_house binary
04:31 rue_house 1 and 0
04:32 rue_house 0 is about 0V and on a 5V circuit 1 is about 5V
04:32 shuggans = 5 volts for on and 0 volts for off?
04:32 shuggans ok
04:33 shuggans so how would you trrigger a non logic level fet from a micro controller then?
04:33 rue_house amplifier
04:35 shuggans which you can build to a specific voltage?
04:35 shuggans or with a dial to et it?
04:36 rue_house !assist circuits
04:36 tobbor Possibly http://eds.dyndns.org/~ircjunk/circuits
04:36 rue_house http://eds.dyndns.org/~ircjunk/circuits/fetdrive.gif
04:36 rue_house that is an ideal optimized circuit
04:37 rue_house http://eds.dyndns.org/~ircjunk/circuits/motordrive.jpg <-- this is a basic circuit
04:38 shuggans I just wired a switch in between my + and the 1 pin, works great
04:39 rue_house heh, solid state
04:39 rue_house ok, images are ready
04:39 shuggans question though - if i were to run OUT from the TX line on my TTL converter board... each signal is 5v?
04:39 rue_house !assist tutorials/elex/feton.png
04:39 tobbor Possibly http://eds.dyndns.org/~ircjunk/tutorials/elex/feton.png
04:39 rue_house http://eds.dyndns.org/~ircjunk/tutorials/elex/fetoff.png
04:39 rue_house see the two circuits
04:40 shuggans yes
04:40 shuggans My switch is making it the 2nd until it presses and bcomes the 3rd
04:40 rue_house yes
04:40 rue_house see the arrow on the fet? how it goes into it?
04:40 shuggans Understand now :)
04:41 shuggans so
04:41 shuggans if instead of this switch
04:41 rue_house there are two types of fets, arrows in, "N channel" and arrow out "P channel"
04:41 shuggans I was wodnering that!
04:41 rue_house P channel fets get used on the + side and N channel fets get used on the - side
04:42 rue_house P channel fets suck, avoid them
04:42 shuggans Ahhh
04:43 shuggans That makes sense why my first try didnt work then
04:43 shuggans also bc I dont think it was a mosfet...
04:43 shuggans :P
04:43 rue_house the N channel fet turns "on" when there is voltage on the gate more + than the source
04:43 shuggans looked up the PN... said it was...
04:43 rue_house by "on" I mean that the electricity flows easier from the S to the D (or whatever dir you want to think of it)
04:44 rue_house a fet is not just on or off
04:44 rue_house it has different levels of on and off
04:44 rue_house 0V is prettymuch full off, and 20V is prettymuch full on
04:45 rue_house there is a region around the 1 or 3V mark where its partly on
04:45 rue_house if you are in ther with a mtoor, the fet will start to get really hot :)
04:46 rue_house this supper sucks,
04:46 rue_house I have to stop eating vacuum cleaners
04:46 shuggans :P
04:46 rue_house so you understand more now?
04:47 rue_house TTL is 5V (or 3.3V)
04:47 shuggans yes
04:47 rue_house but serial wont help you run a motor
04:48 rue_house are you into C programming?
04:48 shuggans so a microcontroller is needed to accept commands you might send it throguh serial and interpret foward as "opn tis gate and this gate"
04:48 rue_house yes
04:49 rue_house but call it 'turning on transistors"
04:49 shuggans Im super fluent in vb.net... C looked alot like mIRC scripting + PHP though
04:49 rue_house heh
04:49 rue_house C has a lot of { and }
04:49 shuggans yes
04:49 rue_house do javascript?
04:50 shuggans As does PHP and mIRC scripting ( I do both as well )
04:50 rue_house ok
04:50 rue_house you planning to get an avr or arduino?
04:50 shuggans I was looking into PIC microcontrollers
04:50 rue_house NO
04:50 shuggans And then found arduino
04:50 rue_house pics are a pain in the ass
04:50 shuggans and THEN found FEZ
04:51 shuggans Looking at the FEZ Domino or FEZ Panda II
04:51 rue_house more support for avr and arduino
04:51 shuggans http://www.ghielectronics.com/catalog/product/256
04:51 rue_house if you want a microcomputer, buy a microatx, but dont get a chip thats supposed to be a computer
04:52 rue_house no I dont reccommend it, there wont be anyone to help you
04:52 shuggans My project is this: Brother built a tank + left me with + and - motor leads and said "Your part is to bring it to life, I built it!"(Im a software engineer in healthcare)
04:53 shuggans and SOOOOO
04:53 rue_house arduino is $20, anyone can help you with an arduino question (electronics or anything)
04:54 shuggans I know nothing about RC... and decided... Im going to build a computer into this tank... run XP on it... write a server application that lsitens on a tcp port for commands from a controller a remote pc
04:54 shuggans and have the server application on the PC in the tank issue serial commands based on the input it receives over the tcp port
04:54 rue_house hmm
04:55 rue_house well your gonna learn a lot
04:55 shuggans lol - I already wrote the controller application + server application
04:55 rue_house yup, the electronics will be the chanllanging bit
04:55 shuggans + have the server application issuing commands to the COM port... which I have a TTL converter board in. I just need to know WHAT to send to the com port, and what to wire up to get it to turn motrs etc
04:56 shuggans I am excited though :D
04:56 rue_house :) I'm just putting a 12V microatx computer on mine and using an avr for slave io
04:56 shuggans this is cool stuff
04:56 shuggans whats an AVR?
04:57 rue_house my motors are 107V, and I'm using 48V of abtteries, which runs everything just fine
04:57 rue_house just got the power converter and avr up today
04:57 rue_house avr is a microcontroller like a pic
04:57 shuggans im not sure hwta our motors are... they dont say, and I cat find info ANYWHERE other than replacement parts based on part #
04:57 rue_house I have basic firmware for mine that I can issue serial commands to
04:58 rue_house read, wrtie the ports, control pwm
04:59 rue_house I bought a tablet t control mine via a webpage
04:59 rue_house I have apache installed on the microatx
05:00 rue_house I should have motor control working by tommorow
05:00 rue_house I should take more pics
05:00 rue_house want to try my wireless video link over some range too
05:00 shuggans nice!
05:01 rue_house !assist robots/buddyII
05:01 shuggans I want to try a 4g usb card in ours...
05:01 tobbor Possibly http://eds.dyndns.org/~ircjunk/robots/buddyII
05:01 rue_house http://eds.dyndns.org/~ircjunk/robots/buddy_II/assembly.html
05:01 rue_house thats the frame for it
05:02 shuggans nice!
05:02 shuggans WAYYY lighter than ours...
05:02 shuggans he built ours COMPLETELY out of steel.
05:02 rue_house add 48V of batteries :)
05:02 shuggans >_<
05:03 shuggans steel frame, steel tracks, goign to have 2 12v car batteries
05:03 shuggans steel turret...
05:03 shuggans Idk whyyyyy he had to have steel... going to make it a heavy robot...
05:04 rue_house steel welds easy :)
05:04 shuggans I knowwww... BUT we ALL have welded aluminum for years... its a family trade. Irrigation pipe.
05:05 shuggans everyone in the fam knows how to do it...
05:05 shuggans ah well.
05:05 shuggans He just wnts it to be tough as nails/
05:07 shuggans So.. Is it stupid / doubling up on things to have a pc in there, AND an arduino?
05:07 Jak_o_Shadows1 no
05:08 Jak_o_Shadows1 You need the arduino (or other uC) to drive the motor and operate hardware like that, while the pc actually controls stuff.
05:08 shuggans ok. Arduino isnt capable of listening on a TCP port + running commandsreceived on it?
05:09 Jak_o_Shadows1 Possibly is, but not a stock arduino. You'd need some other hardware.
05:09 shuggans mk. well... il lstick with the original plan for now
05:10 Jak_o_Shadows1 It's probably the easiest way to get things going quickest
05:10 shuggans So... if I have a vb.net program that is sending the string "Foward" to the com port... which has the TTL converter board in it, and i go fro mthe TX line of the ttl board to the arduinos Rx port, does the Arduino actually receive "Foward"
05:11 shuggans ?
05:11 shuggans and then I can progra mthe arduino to go If "foward" then etc etc
05:12 Jak_o_Shadows1 You can program the ardunio to set various hardware things based on stuf fyou recieve over serial, yes
05:13 shuggans but the "Foward" string is still "Foward" after goign through the TTL conversion board?
05:14 Jak_o_Shadows1 Possibly. I can think of several reasons why it wouldn't be, but i don't know how much they apply. Numbers would almost certainly be safe
05:14 shuggans ok
05:15 shuggans So if I had 1 for foward, 2 for reverse, 3 for right, 4 for left and then 5-8 for the turret controll with 9 as lights on off, 10 as pull paintball gun trigger it would be safer?
05:16 Jak_o_Shadows1 Test it! Get it to light up LED's just for now, but it may or may not work
05:16 shuggans I just didnt know if the ttl board would pass something different that what was put in
05:17 shuggans (I have no arduino)
05:17 shuggans where can I buy one?
05:17 shuggans also: on the TTL conveter board, do I need to jumper the Rx and Tx?
05:22 shuggans (dont know what to look up to buy arduinos... all this stuff comes up "For Arduino")
05:25 shuggans would ou recommend arduino or the atmel stuff?
05:26 Jak_o_Shadows1 arduinos are just special software for atmel stuff.
05:27 Jak_o_Shadows1 special software, but it normally comes with hardware so you can use it easier, but it's not neccessarily neccessary
05:27 shuggans but definately NOT the FEZ stuff?
05:28 Jak_o_Shadows1 You probably dont' want to go for something complicated
05:28 Jak_o_Shadows1 plus, if you plan on chucking a PC in there, no need to get fancy
05:28 shuggans true
05:29 shuggans So where do I find this $20 arduino?
05:33 shuggans http://www.ebay.com/itm/New-UNO-R3-ATMEGA-328-ATmega-16U2-For-ARDUINOs-IDE-/261121234091?pt=LH_DefaultDomain_0&hash=item3ccc09d4ab < - Is his what I need?
05:34 Jak_o_Shadows1 I THINK that'll work, but you'll need a usb b -> usb a cable
05:35 shuggans http://www.ebay.com/itm/EKitsZone-UNO-R3-ATMEGA-328P-ATmega-16U2-For-ARDUINOs-IDE-/261117791454?pt=LH_DefaultDomain_0&hash=item3ccbd54cde
05:35 shuggans Micro USB break easily?
05:36 shuggans I have a ton each kind of usb cable (micro -> USB, USB B -> USB, Mini -> USB)
05:37 shuggans i spose micro or ful sized US makes no difference as long as you secure the board down correctly
06:20 RifRaf how cool is the encoder in these deskjet motors
06:23 Triffid_Hunter shuggans: I think you'll have a lot of fun with the arduino
06:28 RifRaf wow, so i can track a 512 section encoder at 2200rpm
06:30 RifRaf the day has ended well, lcd says 15000 revolutions and counting, this avr stuff is ok
06:59 Triffid_Hunter RifRaf: yeah, when you convert thousands of rpm to cpu clocks per cycle, they don't look nearly as fast anymore ;)
07:01 Triffid_Hunter RifRaf: I hooked a mouse encoder to a stepper driver's step and dir lines once, needed an air compressor to get the stepper spinning at even a moderate pace
07:37 theBear ahh, a rif excited by the magic of electronics... this is a thing i have missed
08:08 ace4016 which rif?
08:08 ace4016 :P
08:09 GuShH RifRaf
08:09 theBear how many are there ?
08:29 Tom_itx how many bears are there?
08:33 ace4016 well, Triffid_Hunter has a rif in there :P
08:34 GuShH in the closet?
08:34 GuShH kinky
08:35 GuShH theBear: laptop or desktop?
08:35 theBear huh what ?
08:35 GuShH think fast!
08:36 GuShH are you a laptop guy or a desktop guy, is the question and why.
08:36 GuShH you can't say both, because I say so.
08:36 theBear i can't, i finally gave in and took painkillers, i seeing my doctor tomorrow, i asked a friend with a very broken ankle for my walking stick back yesterday
08:36 theBear oh, desktop, tho i can do a lot with a laptop if i gotta
08:36 theBear i like several square feet of screenspace
08:36 GuShH like beat someone up with it!
08:36 theBear and a big keyboard so i can break 100wpm
08:36 GuShH you can get screenspace with either though
08:36 GuShH 100, that remains to be sen
08:36 GuShH seen
08:37 theBear pfft, i bet i can still do 120+ on a typing test
08:37 theBear .not today tho
08:37 GuShH WE SHALL SEE
08:37 theBear OK
08:37 theBear DUDE
08:37 GuShH haha
08:37 GuShH I can challenge you since you haven't got your stick around.
08:37 theBear not that i recommend it, but some people do miss yer in that other place
08:37 GuShH Means I don't get beat up with it
08:38 theBear heh, i'm more dangerous without it, my arms are heavier than a hollow ally stick
08:38 GuShH But they don't move as fast on the tip
08:38 theBear oh, that stick
08:38 GuShH Since your arm length plus the stick = faster
08:38 theBear heh, you'd be surprised
08:38 GuShH Think of a whip
08:38 GuShH The speed is "amplified" until at the very tip the sound barrier is no match!
08:39 theBear yeah, but my hands move so fast the metal stick will bend around them, i'd have to literally whip it, and well, that's just silly
08:39 GuShH This is relevant since kangaroo leather is used to build 'em :D
08:39 theBear cmon man, painkillers, i can 't make sense
08:39 GuShH I want a kangaroo leather wallet dammit.
08:39 theBear heh, i gots one
08:40 GuShH best leather out there
08:40 theBear i swap you for the lower half of your spine, even throw in a nice black walking stick
08:40 GuShH my lower half is not pristine
08:40 GuShH I wake up in pain every day.
08:40 theBear how much pain ?
08:40 GuShH enough that it's hard to get up at times
08:40 GuShH and I would consider killing if that meant getting rid of it
08:41 theBear hmmm, ok, so it wouldn't be a change.. damn
08:41 GuShH Feels like someone left a pair of vise grips stuck to my spine
08:41 theBear i'm not fucking happy, sure i was missing way too many days of work, but last night i barely made it back from the shop a few hundred meters up the road
08:42 theBear and i'm gonna have to get a prescription for something tomorrow, which sigh
08:42 theBear been taking the pills that ruined my stomach every 36 hours
08:43 theBear and a card in my pocket cut the ffc to the front half of my fone on friday, so now i gotta wait till i got some money on the card and order that shit from overseas
08:43 Modeuse wer sucht mich?
08:44 theBear looks like i really aint getting markedly better ever again
08:44 theBear erm, ich non sprechen der umm
08:44 theBear doitch
08:45 GuShH :/
08:45 theBear wtf ? just testing this new (new app from my window manager/desktop env) graphic viewer and pictures of a naked girl smoking a bong popped up... i didn't know i had those, maybe they're complimentary
08:47 GuShH lol
08:47 GuShH looking at those cheap samsung galaxy tablets.... no gps? the hell
08:47 GuShH to me the whole idea of such device is to have certain functionalities that would otherwise require EXTRA CRAP in your pocket.
08:47 GuShH and thus extra cost.
08:48 theBear meh, tablet, bluetooth it to yer mobile for gps
08:48 GuShH what if yer mobile don't have no stinkin gps
08:48 theBear then it's stupid :)
08:49 GuShH most tablets seem stupid to me
08:49 GuShH they only seem useful to read a pdf or watch some video on the couch
08:49 GuShH you can do that with just about any other device though
08:49 GuShH so, it's got to be the hipster points.
08:50 ace4016 i'd say they're decent for casual games, but their games suck
08:50 ace4016 most anyways
08:50 theBear mmm, they're kinda handy socially, like if yer having a coffee and someone wants to show you a website
08:50 ace4016 that's what smart phones are for
08:50 ace4016 although they do make better laptops than laptops do :P
08:51 theBear yeah, but you got a table, why not have a huge screen ?
08:51 theBear my smart phone makes an awesome laptop when the stupid ffc to the keyboard/screen/mic isn't cut
08:51 ShH pats the
08:52 theBear heh, that actually helps, i must be having a bad day
08:52 GuShH I looked at the Lg Gt540 and nearly threw up in my mouth.
08:52 GuShH what the hell were they thinking?
08:52 theBear ok... i err, don't really see ANY kind of media these days, well, unless you count cartoons
08:53 theBear i only know what i see here
08:53 GuShH It's the offspring of a palm v and a modern toaster
08:53 theBear and of course everything there is to know about liquor and when and where to cigarettes
08:53 theBear erg, that is horrible
08:54 GuShH "it's like two iphones high"
08:54 GuShH lol
08:54 GuShH context: http://androidlegend.com/wp-content/uploads/2012/07/LG-ptimus-GT540.jpg
08:54 GuShH if I worked for LG and I saw that, I would whip their ass and fire them in a heartbeat.
08:55 GuShH "chrome trim, check. dildo profile, check, heavy as a brick, check!"
08:55 theBear wow, that is... chunky
08:55 theBear hehe
08:55 theBear dildo profile :)
08:55 theBear cannot be unseen
08:55 GuShH it better have a nuclear reactor or something in all that space
08:56 theBear nah, leprachauns on hamster wheels
08:57 theBear hmm, that german dude is awful quiet
08:57 theBear maybe he's swiss and i offended him
08:57 GuShH that explains the rattling inside, must be the gold coins
08:57 GuShH offer him some swiss cheese
08:57 theBear heh
08:57 theBear lol
08:58 GuShH well talk about crappy phones, the galaxy Y reminds me of the first iphone
08:58 GuShH chunky and half assed
08:58 GuShH ...it even got them in trouble
08:58 GuShH why are companies acting like this?
08:58 GuShH are they really full of cottonheads?
08:59 theBear 'cos consumers are increasingly non-discerning and stupid
08:59 GuShH "we must compete against apple by ripping off their design and calling it ours"
08:59 theBear oh, and the cottonhead thing
08:59 GuShH I don't care for apple, just do your own, better thing instead.
09:00 theBear mmm, i've grown to quite like htc over the last 11 years or so... always good solid products, very servicable, very reliable, original designs
09:00 GuShH and their market segmentation seems to be a timeline of the iphone in fact
09:00 GuShH cheapie, looks like the first iphone, the most expensive galaxy... looks like the newer iphones
09:00 GuShH idiots
09:00 theBear heh
09:03 theBear meh, i need to recline a bit.... have fun :)
09:03 GuShH Modeuse: achtung!
09:03 Modeuse ?
09:03 theBear heh, well played
09:04 GuShH zeeee B�r ist in da haus?
09:04 GuShH parteei!
09:07 GuShH mein deustch... sucks
09:07 GuShH oh turns out that galaxy tablet has gps, not bad then.
09:08 ace4016 most these days seem to
09:08 ace4016 though a bit pointless without being able to download the map data
09:11 GuShH ace4016: a friend keeps complaining about the "locked down" android on his
09:11 ace4016 o.0
09:12 ace4016 does he not know how to "jailbreak" them?
09:12 ace4016 also, it's a toy...i don't see the point wasting time on that
09:12 ace4016 the hardware is fairly piddl
09:12 ace4016 y
09:12 ace4016 piddly*
09:15 theBear unlocking it a little is handy... for example i wouldn't be able to vnc my screenless phone right now if i hadn't go su working
09:16 theBear not to mention the startup screen being a little android eating a apple and saying "iphone aint got shit on me" :)
09:18 GuShH ace4016: don't know which one hes got, it has a quad inside
09:18 GuShH theBear: heh
12:11 rue_bed I thought the andoid was putting the peice back in the apple saying "look, I fixed it!"
12:12 ace4016 hehe
12:12 ace4016 not quite
12:12 ace4016 no OS is perfect :P
12:12 rue_bed no
12:13 rue_bed open source has an interesting software lifecycle caveit
12:14 rue_bed every so often a really good program comes up, and then itmatures and stops being developed, then it gets out of sync with dependencies and is replaced by something completely inferior thats development cycle starts agian
12:17 ace4016 none reach perfection
12:17 ace4016 well...i lie
12:17 rue_bed povray and Xamp did
12:17 ace4016 well, i lie again
12:17 ace4016 i'm just a liar
12:18 ace4016 povray is not perfect :P
12:18 rue_bed whats wrong with povray?
12:18 rue_bed was
12:18 rue_bed I dont think its been worked on for 5 years now
12:20 rue_bed another fine one fallen is camserv
12:21 ace4016 well, development of utilization of more modern technology is something programs should constantly try to do...and if its last update was 5 years ago, there goes a major flaw
12:21 rue_bed usually what happens is the lead stops working on the project and everyone forgets it exists
12:21 ace4016 heh
12:21 ace4016 that's not good
12:22 rue_bed and then someone tries to create a program that does the same thing, and its junk for hte first 3 years
12:22 ace4016 also, they seem to rarely be innovative..though i guess most commercial programs aren't either...
12:22 ace4016 oh well
12:22 rue_bed freescad
12:23 rue_bed a program can reach a point where it just needs to stay up with changes to the gui libraries
12:23 rue_bed debian is bad for dropping support for older gui libs
12:25 GuShH what's this? http://gushh.net/tmp/thing.jpg
12:25 ShH nudges the
12:27 rue_bed those are the moths that the blackbird eats
12:27 GuShH ???
12:27 GuShH rue_bed: we were about to wash the cars and that thing was just on the trim
12:28 GuShH weird looking moth! so aerodynamic though
12:28 GuShH I bet most modern jet fighters are based off of that!
12:28 rue_bed er not blackbird
12:28 rue_bed whats that jet called
12:29 GuShH thunderbird?
12:29 GuShH probably not
12:29 GuShH had a bunch of those do a low flyby where I used to live
12:30 GuShH turned out to be a french aerobatic team
12:30 GuShH bastards had premission to do whatever they wanted
12:30 GuShH nearly shit my pants.
12:30 rue_bed ok I'm go like up
13:15 ace4016 looks like a delta wing..
13:16 ace4016 su-4something has it, as well as the concorde jet
13:48 GuShH ace4016: heh, still an unidentified moth!
13:48 ace4016 lets call it a concorde moth!
13:48 ace4016 we can totally get a nobel prize out of it
13:49 GuShH o.O
13:53 ShH goes back to whatever he was doing with the chai
14:34 shuggans L298 Chip is an H-Bridge circuit built into a chip right?
14:45 GuShH theBear: bah :( my small chainsaw has low compression all of a sudden
14:46 GuShH I think it was set too lean, it's the only engine I own that I never tuned up
14:46 GuShH cylinder looks ok from the exhaust port looking onto the intake side, but it's usually the exhaust that gets scorred
14:46 GuShH higher heat build up...
15:15 trexmatt Hi. Does anyone know of a way to measure or compute centripetal acceleration? Right not I'm thinking of measuring current turn radius somehow and then using a = V^2/R to get it. Any ideas?
16:41 TELunus trexmatt, if you can measure turning radius and velocity that will work. Alternatively if you know the orientation of the local gravitational field (or if your centripetal accelerations are large enough that you can ignore it) you can use an accelerometer.
16:50 rue_house Tom_itx,
17:35 Undine do i need a rotary table in order to mill metal with my abb 6 axis robotic arm?
17:35 Undine they seem expensive...
17:44 rue_house "... truck with the meaning of life, the universe, and everything expressed neatly on the back in the form of a 2 digit number."
17:44 rue_house Undine, mill with an arm?
17:44 rue_house wood?
17:49 Undine mill with an arm
17:49 Undine for metal
17:49 Undine spindle on an arm to be specific
17:49 Undine for metal
17:50 Undine do i need a fixated placement for this metal milling with a spindle,
17:50 Undine and if so, is a "rotary table" what i need?
18:51 rue_house what kinda 6 axis arm
18:51 rue_house wpherical?
18:51 rue_house revolute?
18:51 rue_house sylindrical?
18:51 rue_house slkdfj
18:52 rue_house !time
18:52 tobbor My watch says its 04:42PM Sun Jan 13 2013
18:52 rue_house ok now I really really need lunch
18:55 TELunus tobbor's watch is wrong.
18:55 rue_house hmm
18:55 TELunus It's: 04:42 now.
19:16 shuggans So I bought an arduino Uno...
19:17 shuggans Trying to use the serial event sample to receive data from a TTL converter board
19:17 shuggans hand the TX on the TTL board connected to the RX of the arduino. is this correct?
19:21 Tom_itx yuppers
19:25 shuggans Its doing nothing :(
19:26 shuggans I combined the blink sample with the serial input sample so Id know if it was rteceiving stuff... but no blinking is happenning when I send from the tx on the rs232 to ttl converter board.
19:26 shuggans Do I need to jump the Rx and Tx of the ttl converter?
19:27 Tom_itx GND -> GND, RX <- TX, TX -> RX
19:28 Tom_itx TTL converter??
19:28 orlok 11 days
19:28 Tom_itx like a max232?
19:28 Tom_itx how many min?
19:29 shuggans yes MAX232
19:29 orlok Tom_itx: DOnt know, they havent specified the time
19:31 Tom_itx shuggans, http://tom-itx.dyndns.org:81/~webpage/how_to/atmega168/mega168_rs232_index.php
19:34 shuggans ???
19:35 shuggans I have this: http://www.ebay.com/itm/150786681292?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 and a arduino Uno
19:36 Tom_itx so?
19:36 Tom_itx what are you trying to do with it?
19:36 shuggans Just light up the LED on pin 13 of the arduino when it receives serial data
19:36 Tom_itx what i showed you is basically the same thing
19:38 shuggans String inputString = ""; // a string to hold incoming data
19:38 shuggans boolean stringComplete = false; // whether the string is complete
19:38 shuggans int led = 13;
19:38 shuggans void setup() {
19:38 shuggans pinMode(led, OUTPUT);
19:38 shuggans Serial.begin(9600);
19:38 shuggans inputString.reserve(200);
19:38 rue_house Tom_itx, have a schematic in you magic book for a non-automatic winshield wiper cicuit S10?
19:38 Tom_itx i bet
19:38 shuggans Is there any way I can show you guys code? :P
19:39 rue_house canb I coax a opy from you?
19:39 orlok pastebin?
19:39 Tom_itx you gonna have to be more specified in yer request mr _house
19:39 Tom_itx shuggans, pastebin
19:39 rue_house can you get me a copy of the image for hte winshield wiper schematic?
19:40 rue_house the only ones online are for the ones with the automatic timer
19:40 shuggans http://pastebin.com/xbg5ZPUX
19:40 Tom_itx we will have to discover what book it is in first
19:40 shuggans Am I doing this wrong?
19:40 Tom_itx mine should have it all
19:40 Tom_itx shuggans, i am not a fan of arduino
19:40 Tom_itx i'd rather code it in c
19:41 Tom_itx if you look at my code, it will transmit a pair of characters to a pc terminal
19:41 shuggans I was going to buy a PIC + a PicKit + do thiat... but most here said to go arduino to start
19:41 shuggans so I boguht this board... :P
19:41 Tom_itx if you compare that to the arduino gobbledygook you can match what it does
19:41 Tom_itx ok
19:41 Tom_itx well at least you got an avr
19:41 Tom_itx rue and i can help you get goin
19:42 rue_house shuggans, you might have more luck with arduino questions in #arduino
19:42 shuggans Is the srieal event talking about USB... or the Rx / Tx terminals?
19:42 Tom_itx but you must provide us incentive
19:42 shuggans serial*
19:42 shuggans Incentive... like.....?
19:44 rue_house shuggans, arduino is a software set ontop of an avr
19:44 rue_house we work with the avrs directly and do not use the arduino libraries
19:44 Tom_itx section 8E Wiper/washer system
19:44 rue_house so, you can ask arduino questions in #arduino with more success than you will get here
19:45 rue_house we can help with any electronics stuff
19:45 Tom_itx rue_house what are we looking for?
19:46 rue_house everything from the switch to the motor
19:46 Tom_itx ok it may or may not be in this book
19:46 Tom_itx i have 3 though
19:48 Tom_itx alright, hold on i'll take a pic and see if this is what you want
19:49 Tom_itx you'll have to wait a bit
19:49 Tom_itx the camera battery is dead
19:55 Tom_itx k i found a micro sd for the phone, i'll try that
20:00 rue_shop3 :)
20:00 Tom_itx just about got it
20:02 Tom_itx http://tom-itx.dyndns.org:81/~webpage/rue/wiper/
20:02 Tom_itx ok if that's not it, i'll get out the schematic book
20:02 Tom_itx 005
20:02 Tom_itx is what you want
20:06 rue_shop3 is this killing your connection?
20:06 Tom_itx oh let me reset the router... sorry
20:06 rue_shop3 I'll wait
20:09 Tom_itx see what that does now
20:09 rue_shop3 much better
20:09 Tom_itx is that what you're after?
20:10 rue_shop3 just pouring over it
20:10 Tom_itx 5 is the one
20:11 orlok I got an email 4 days about about itelescopes.net opening an australian setup
20:11 orlok at Siding Springs Observatory
20:11 Tom_itx the other 2 are for testing
20:11 orlok which is in the news today due to bushfires
20:11 orlok everybody evacuated, buildings burnt down, etc
20:11 Tom_itx not cane fires?
20:12 orlok http://www.abc.net.au/local/stories/2013/01/14/3669058.htm?site=sydney
20:12 orlok the main buildings survived
20:12 rue_shop3 tom, I think that has everythign
20:12 Tom_itx ok
20:13 rue_shop3 I asked about the price of a new wiper motor, $100, but he asked me if it has the delay or not
20:13 rue_shop3 I asked him what the delay one was worth, $110
20:14 rue_shop3 I dont know if I want to finish doing my own intermittent or mod it in
20:14 Tom_itx you can test it with those other 2 pics
20:14 rue_shop3 from what I can tell, I'd need a new lever
20:15 Tom_itx 7 is the delay isn't it?
20:15 rue_shop3 yes
20:15 Tom_itx just a couple resistors and diode
20:16 rue_shop3 from that, it looks like the timer board he said wasn't incuded is on the wiper motor itself
20:16 Tom_itx and a different switch
20:16 rue_shop3 which adds up with what I was seeing on the webpages
20:16 rue_shop3 yes
20:16 Tom_itx the wiper motor is probably the same
20:16 rue_shop3 it looks like they use the same harness tho
20:16 Tom_itx yeah
20:17 rue_shop3 jsut a differnet switch and mtoor
20:17 Tom_itx you think the motor is different?
20:18 Tom_itx i've got an exploded view of it :)
20:18 rue_shop3 has a citcuit board on it for doing the timing
20:18 Tom_itx ahh
20:19 Tom_itx 103 in the exploded view
20:19 Tom_itx circuit board
20:19 Tom_itx the motor could be used if you made your own delay
20:20 Tom_itx the exploded view looks the same except the circuit board and top cover
20:20 rue_shop3 It occured to me that using the hall from a muffin fan I can make a switch to operate a door led
20:20 rue_shop3 put a magnet on it, when it goes by one way the led comes on, by the other the led goes off
20:20 rue_shop3 I think I want to make my own delay for the wipers, I have an idea, that uses the T10
20:21 rue_shop3 I cant get avrdude to recognize that programmer right
20:21 Tom_itx you done with the books now?
20:21 rue_shop3 I'll have to play more
20:21 Tom_itx mine?
20:21 Tom_itx it should
20:22 rue_shop3 yea, not sure whats wtong
20:22 Tom_itx i gave you the line i used
20:22 rue_shop3 yes, all the options were the same on mine
20:22 Tom_itx and i tested it on studio before shipping
20:22 rue_shop3 it complained a usb id was wrong or womthing
20:22 rue_shop3 yea, I havnt' tried to debug it yet
20:23 rue_shop3 at first it wouldn't recognize at all, and I realized I had the other one plugged in too
20:23 rue_shop3 same usb id, avrdude didn't like tha
20:26 rue_shop3 oh yea, is the pinout of the isp (6 pin) for the old M32 boards you sent me the botched pinout?
20:26 rue_shop3 if you remember, I was going to take a meter to it
20:26 Tom_itx i don't remember, i think i fixed them but i've slept since then
20:26 rue_shop3 I was given 1500 red leds, think I should make an 11x11x11 cube? }:)
20:27 Tom_itx check one you've already used
20:27 rue_shop3 I'v never programmed them by their port, It seems I'v used my baords for doing all theprogramming
20:27 Tom_itx wait.. the ISP on the avr32 experimenter?
20:27 Tom_itx it's ok
20:27 Tom_itx 6 pin?
20:27 rue_shop3 yea
20:28 Tom_itx lemme hook one up..
20:28 rue_shop3 the dip baords
20:28 Tom_itx i got one here
20:28 rue_shop3 I remember that erronious schematic went around quite a bit
20:29 Tom_itx i don't remember if i can power it via usb though..
20:29 Tom_itx apparently so
20:29 Tom_itx yeah it works fine
20:30 Tom_itx pin 1 is left side toward the board edge
20:30 Tom_itx by the cap
20:30 Tom_itx signature: 0x1E 0x95 0x02
20:31 Tom_itx i'm not sure i have a working avrdude on windows here
20:32 Triffid_Hunter arduino ide comes with one
20:33 Tom_itx my libusb drivers are all screwed up
20:34 Triffid_Hunter doesn't need libusb if you're using a usbserial converter
20:34 Tom_itx this is ver 5.8
20:34 Triffid_Hunter only needs libusb for ones like the adafruit avrisp
20:34 Tom_itx he's trying to get my programmer to work with it
20:34 Tom_itx and i was gonna try one here
20:34 Tom_itx i generally use studio to program
20:36 Tom_itx yeah this one doesn't work
20:40 theBear eh ? studio doesn't need windows anymore ?
20:40 Tom_itx yeah it does
20:41 theBear mmmk, good to know these things
20:50 Tom_itx ok i can't seem to get it working on ubuntu atm
20:53 atom1 ok the t10 is blinking now
20:53 atom1 avrdude -c avrisp2 -P usb -p t10 -v -U flash:w:/home/tom/avrtest/Tiny10_asm/t10blink.hex:i
20:54 atom1 mmm i don't have a m32 blinky handy
20:57 atom1 avrdude -c avrisp2 -P usb -p m128 -v -U flash:w:/home/tom/avrtest/atmega128/blink_led.hex:i
20:57 atom1 also works on the 128
20:58 atom1 rue_house, do you have root permissions for the port?
20:58 rue_shop3 the avrdude I'm using has a problem with the programmer
20:58 atom1 want this one?
20:59 atom1 it's ver 5.10
21:01 rue_shop3 interesting, I used your 10 pin adapter to program one of my boards and it was fine
21:02 atom1 i'm not sure where avrdude is on this install
21:03 atom1 where do default programs go?
21:03 atom1 under /usr ?
21:05 rue_shop2 .on this system
21:05 rue_shop2 root@freebee5:/files/programming/c/avr/atmega32/ioman# which avrdude
21:05 rue_shop2 /usr/bin/avrdude
21:06 atom1 ok there it is
21:07 rue_shop2 it'll be soemthing to do with the 6 pin
21:07 atom1 i don't see the conf though
21:07 rue_shop2 I'll work on it later
21:07 rue_shop2 root@freebee5:/files/programming/c/avr/atmega32/ioman# locate avrdude.conf
21:07 rue_shop2 /etc/avrdude.conf
21:07 atom1 i figured it would be in the same dir as avrdude
21:08 atom1 ok it's there
21:11 rue_shop2 this is all good
21:11 rue_shop2 its soemting with the 6 pin, dont know what
21:11 rue_shop2 I'm haivng problems functioningwithout 2 monitors
21:13 rue_shop2 I should put fuse programing lines in my makefile
21:13 rue_shop2 I only use 2 configs
21:22 rue_shop2 !thislog
21:22 tobbor This one: http://rueshouse.dyndns.org:82/~ircjunk/irclogs/html/%23robotics-2013-01-14.html
21:22 rue_shop2 http://rueshouse.dyndns.org:82/~ircjunk/irclogs/html/fuses.htm
21:22 rue_shop2 damn
21:22 rue_shop2 what did I call it
21:22 rue_shop2 !assist avr/fuses.html
21:22 tobbor Possibly http://eds.dyndns.org/~ircjunk/avr/fuses.html
21:22 rue_shop2 aha
21:23 rue_shop2 !time
21:23 tobbor My watch says its 07:14PM Sun Jan 13 2013
21:23 rue_shop2 have to work tommorow, lets see if I can keep from screwing this up
21:28 rue_shop2 avrdude -c avrisp2 -P usb -p m32 -e -U flash:w:$(PRG).hex
21:30 rue_shop2 avrdude -p m32 -U hfuse:w:0xD9:m -U lfuse:w:0xEF:m
21:30 rue_shop2 avrdude -c avrisp2 -P usb -p m32 -U hfuse:w:0xD9:m -U lfuse:w:0xEF:m
21:37 rue_shop2 the new robot here uses a 48V battery bank, little intimmidating
21:37 rue_shop2 just waiting to be bitten by it
21:40 rue_shop2 YES
21:40 Jak_o_Shadows yeah, that could hurt
21:40 rue_shop2 READY. <-- never been happier to see that char[]
21:46 rue_shop2 pwm channels on 3 and 28
21:46 rue_shop2 255 is off :/
21:47 rue_shop2 no flyback diodes so I have to go nice on it
21:47 rue_shop2 enguaging motor power...
21:47 rue_shop2 .. and robot drove off table...
21:47 rue_shop2 (j/k)
21:49 rue_shop2 oh this pwm freq is gonna make a lot of noise...
21:50 rue_shop2 so I guess I can putz around and make the voltage monitor board...
21:51 rue_shop2 need to mount the computer at some point too
21:56 Tom_itx so did you get it to work?
22:06 rue_shop2 not the 6 pin
22:06 rue_shop2 but the programmer works, I'm just using one of my boards to reflash the chip
22:07 rue_shop2 everything is find otherwise
22:07 Tom_itx the 6 pin and 10 pin have miso mosi reversed
22:07 Tom_itx pin 1 is different on both iirc
22:07 Tom_itx i forget which it is, i didn't look
22:07 rue_shop2 if I use your 10 pin adapter to one of my boards its ok
22:07 Tom_itx yeah
22:07 rue_shop2 if I use 6 pin to your board its no go
22:07 rue_shop2 I'm writing it off as 6 pin evil
22:08 Tom_itx ok, i just looked at the bottom of the board and the 6 pin has been jumpered
22:08 Tom_itx so i did have them backward on it
22:08 Tom_itx swap the 2 lines
22:08 rue_shop2 hah :)
22:08 rue_shop2 cool
22:08 Tom_itx sry
22:08 rue_shop2 ah, yes, back in the day!
22:08 rue_shop2 np
22:08 Tom_itx i cut and jumpered all on the bottom
22:09 rue_shop2 I modded them pretty good to fit my stuff
22:09 Tom_itx need a pic?
22:09 rue_shop2 no I'm ok
22:09 Tom_itx i didn't bother looking for a jumper earlier
22:10 rue_shop2 it seems that trying to stay awake is taking up all my contentration, I'm not getting anything done
22:10 rue_shop2 I want to be making something on the lathe
22:17 rue_shop3 SWEEET I FOUND THE RADIOACTIVE CALIBRATION SAMPLE!
23:06 Ademan Does anyone have a recommendation for resistor and cap values to have on hand?
23:11 DagoRed What are you trying to accomplish?
23:13 rue_shop3 resistors, 470 ohm, 1k 10k capacitors, .01uf .1uf 1uf 10uf 100uf 1000uf
23:13 rue_shop3 lots of 1k resistors, lots of 1uF caps
23:22 Jak_o_Shadows I may be using the arduino environment on an msp430, but it's on linux and it's a compiler
23:41 Jak_o_Shadows so, does debian have a rolling release version?
23:52 Ademan thanks rue_shop3 !
