00:09 orlock i should have some 8266's today or tomorrow
00:09 orlock playing with the 433/315Mhz gear was fun, but pointless in the end
00:10 orlock because the receivers crank the gain up if they dont receive any data, it would just pick up noise when the transmitter was waiting for data from the temp/humid sensor
00:12 orlock rue: https://espressif.com/en/products/esp8266/ - seen these of course?
00:13 rue_house I dont want to hear about the stupid wifi chip
00:13 orlock hahaha
00:14 orlock i guess thats a yes then?
00:14 orlock whole cpu, not just a wifi chip
00:15 orlock and better than using a whole $25 router
00:31 rue_house yea we been hearing about NOTHING else latley
00:32 orlock well, i also ordrede from the same place a pan/tilt webcam mount
00:32 orlock with two servos, webcam and mounting hardware for $25 or so
00:33 orlock rue_house: Seen the new flavor of cheap arm computer/router?
00:34 rue_house maybe you didn't notice how I jump to a new processor every time a new ones comes out
00:35 rue_house or NOT!?
00:35 rue_house I'm not switching to something else
00:35 orlock 64 meg of ram, 16 meg of flash, 2x eth, USB, wireless, $25-30
00:35 rue_house not rabbit
00:35 rue_house not arm
00:35 orlock hey, arm's aint new!
00:35 rue_house what are some of the other 500 ones that have come out since ?
00:36 orlock this is the same chip they use on the arduino wireless shields
00:37 orlock except a whole router got under half the price
00:37 rue_house great great
00:37 rue_house and yes, I'v heard for a month now how its gonna be the greatest thing ever
00:40 rue_house "there is a new cpu out with wifi, its gonna make everything wifi cheap, its gonna be the greatest thing ever
00:40 rue_house "there is a new cpu out with wifi, its gonna make everything wifi cheap, its gonna be the greatest thing ever"
00:40 rue_house "there is a new cpu out with wifi, its gonna make everything wifi cheap, its gonna be the greatest thing ever"

00:41 rue_house "there is a new cpu out with wifi, its gonna make everything wifi cheap, its gonna be the greatest thing ever"
00:41 rue_house "there is a new cpu out with wifi, its gonna make everything wifi cheap, its gonna be the greatest thing ever, its just around the corner, it'll be available next week"
00:43 rue_house "there is a new cpu out with wifi, its gonna make everything wifi cheap, its gonna be the greatest thing ever, its just around the corner, it'll be available next week, its the greatest thing ever"
00:44 orlock Heh, its not going to make everything cheap - but it is cheaper than trying to configure duplex comms using those 315/433Mhz toys
00:45 orlock the 8266 still uses serial comms and is configured via AT commands
00:51 rue_house on a note relivent to something, I think my list library works
00:52 wolfmanjm AFAIK no one has gotten the 8266 to actually work yet ;)
00:52 rue_house go back to worshipping it, I have real thing to focus on
00:54 orlock rue_house: Well, when/if i get it working, i'll let you know how it compares to one of the 433Mhz transceiver units
00:54 wolfmanjm Now he edison is a real breakthrough ;)
01:36 rue_house about about the H8
01:36 rue_house and the z8
01:36 rue_house and the 68hc16
01:36 rue_house or the hc908
01:37 rue_house what about the rabbit?
01:37 rue_house I'm sticking with avrs
01:38 rue_bed-aok if I need an arm, I'll use something intel based so I dont have problems running linux on it
04:54 deshipu paper plane gun https://www.youtube.com/watch?v=J7K91g8yG_w
05:28 RifRaf pretty cool
07:25 Tom_itx rue_bed-aok, if i need an arm i'll use the 2 i was born with
10:48 TELunus Tom_itx the arms we're born with aren't as strong or precise as ones we can build.
10:53 deshipu the ones we can build are not regenerating though
10:54 deshipu and don't become better with training
16:04 Hyratel1 for some reason, all the old gearboxes in the shop had been taken apart so there's parts from at least four toughboxes, two toughbox minis and (not anymore now) two CIMple boxes all dumped in a pile of bullshit and shoved on a shelf
20:07 rue_house so you have what you need to make a gearbox
20:08 rue_house TELunus, how are you doing on designing a robot arm that can build the robot arm that it is
20:26 TELunus Haven't done much work on it. I think the first project for that is going to be just building a simple robot arm to get some arm experiance.
20:28 rue_house I have a thing going , you shoudl come over and do one
20:28 rue_house how about eeproms from fg?
20:31 rue_house hmm, I thinkt he pbx is killing another hard drive
20:31 rue_house its eaten 5 already
20:36 orlock my 8266's arrived!
20:38 rue_house bah, I have lots of 8250, how much better could a 8266 be
20:39 rue_house I even have 8255
20:40 rue_house "I dont know whats keeping me alive, but I know its not what I'm eating"
20:42 Tom_L eat better then
21:24 Tom_L rue_house
21:24 Tom_L what were those PATA SATA boards you got?
21:24 Tom_L looks like the dude cancelled mine
21:44 Cheekio anyone taking the edx underactuated robotics course?
21:44 Cheekio They released their first week of lectures yesterday. I'm working on the homework, and surprise surprise it's tough
21:44 Tom_itx and you're looking for homework help?
21:45 Cheekio Nope. I just wanted to inform people.
21:45 Cheekio It's a great course so far.
21:45 Cheekio I'm just really rusty on linalg so it's a little tough feeling comfortable with these equations
21:46 Cheekio I was going to pontificate in another channel about what the course is like so far, but none of my friends are taking it so it'd just be another monologue from me with no response
21:47 orlock linear algebra?
21:56 Cheekio Yeah
21:58 Cheekio The general form of "The Manipulator Equations" includes B, a input mapping matrix
21:58 Cheekio So I don't really get how that works
23:17 Cheekio Got my first hand cramp
23:17 Cheekio went through the first lecture again
23:18 Cheekio watching closely for definitons of q, u, x, and how H, C, G, and B exist as matrices helped.
23:20 rue_house I hate matrixies
23:20 Cheekio I didn't really like linalg myself
23:21 rue_house but I have an input arm device, I need to make up some forward kinematics for
23:21 rue_house well I ahve to write the avr code
23:21 rue_house I'm thinking interrupts continiously sample the channels while the main loop spools them over the serial as fast as it can
23:58 rue_house I need a protocol, anyone have one?
23:59 rue_house I need framing data
23:59 rue_house and a channel identifier
23:59 rue_house and data
23:59 rue_house 16 bits of data
