01:21 AM flav0r: HEY !!!!
01:28 AM flav0r: I’M BACK !
02:11 AM ace4016: hi back, welcome to robotics :P
02:43 AM rue_bed: hi
03:04 AM flav0r: dude
03:04 AM flav0r: LTNS
03:04 AM flav0r: THE ROBOT ???
03:04 AM flav0r: PROGRESS ?
03:05 AM rue_bed: ?
03:22 AM flav0r: dude
03:22 AM flav0r: the big mechanical man
03:42 AM rue_bed: mm, needs more progress
08:38 AM gartt: That's the life of a tinkerer. There's no such thing as a completed project :P All are neverending
11:28 AM rue_mohr: but all the projects get passion, unlike day job projects
11:30 AM gartt: Heh, true. And it's a good thing that they're not finished. There's no point in starting them if there's no room to continually improve them
11:30 AM rue_mohr: Sometimes when your working on something stupid, you learn an important thing that comes in handy for something thats not stupid tho.
11:32 AM gartt: That's true too, so it's not wasted time. Future investments in capability
11:32 AM rue_mohr: If it weren't for the LED ROM FSM I did, I would not have had the realization about current detection that lead me to my scanless keyboard decoder
11:35 AM rue_mohr: http://ruemohr.org/~ircjunk/distractions/ledromfsm/slide.htm
11:35 AM rue_mohr: there is a later version I cheated with, VCC needs to be run a bit high
11:36 AM rue_mohr: leds were burned out to program the 8x8 array
11:37 AM rue_mohr: http://ruemohr.org/~ircjunk/distractions/FSMservo/slide.htm
11:37 AM rue_mohr: on this one, the ROM changes the 555 interval, which is cute
11:37 AM gartt: Buy, you sure love low-level stuff... But you get it done
11:38 AM rue_mohr: I'm surprised how far the rom stuff can go
11:38 AM rue_mohr: http://ruemohr.org/~ircjunk/distractions/scanned7seg/slide.htm
11:39 AM rue_mohr: 12bit -> 3 hex digit decoder
11:39 AM gartt: rue_mohr: Cool
11:39 AM gartt: You put some time into that
11:39 AM rue_mohr: not much
11:40 AM rue_mohr: ideas occur and I go chasing them like a lightening bolt
11:40 AM rue_mohr: corners and forks everywhere
11:41 AM gartt: Well, if it's an interesting project, the motivation is free. And nothing beats waking up at night with random new good ideas and writing them down to try later on a project
11:42 AM rue_mohr: http://ruemohr.org/~ircjunk/distractions/lcdMessage/p1180029.jpg counter/rom use 4 bit mode to send a message to an hd44780 lcd, rom has auto stop on 555
11:42 AM gartt: rue_mohr: You're an electrical engineer by trade?
11:42 AM rue_mohr: nope
11:43 AM rue_mohr: electrician
11:43 AM rue_mohr: its realated, but not too much to take away the fun
11:43 AM rue_mohr: http://ruemohr.org/~ircjunk/distractions/lvdt/slide.htm
11:44 AM rue_mohr: turns out the world has been doing lvdts wrong this whole time
11:45 AM rue_mohr: oh and that totally opened me up to using bipolars for sample and hold
11:46 AM rue_mohr: that was a shocker
11:46 AM Tom_L: i think you just like winding coils
11:46 AM rue_mohr: hah
11:47 AM rue_mohr: I'm not good at it yet :(
11:47 AM Tom_L: cnc it so you can enter the number of windings
11:47 AM rue_mohr: hah, I'm close
11:47 AM rue_mohr: the coil lathe has an auto slow-and-stop
11:48 AM rue_mohr: its so nice to be able to stop and back up without trying to keep track of turns
11:49 AM rue_mohr: its too bad the lvdt stuff was blown away by the lvdc
11:49 AM rue_mohr: I had that down to like $1 in parts
11:54 AM Tom_L: or at least put a turn counter on it
12:03 PM rue_mohr: it does
12:03 PM rue_mohr: avr, 8 digit 7 segment display
12:03 PM rue_mohr: I can preset the number of turns to have it stop me at
12:14 PM Tom_L: ahh
08:17 PM SpeedEvil is now known as Guest75
10:53 PM rue_mohr: I thought those tables were the success to your feed rate
10:53 PM rue_mohr: s
10:58 PM flav0r: hey whats up !
