00:39 rue_more need to drive some pwm thru it and see whats happening
00:40 rue_more it also turns out the power supply was buckling
00:54 GargantuaSauce not surprising
00:54 GargantuaSauce even my relatively tiny one peaks at like 12-15A in certain situations
01:15 rue_house mine are dc motors, not hobby srevos
01:15 rue_house 24V from a vending machine
01:57 rue_house yay, I did my interserver backups
01:57 Hyratel How do you make a solar system?
01:58 rue_house well
01:59 rue_house one way is to get a solar cell, a battery charge controller, and a battery, and a load and connect them all togethor
01:59 Hyratel You planet
02:00 rue_house another way is to start with lots and lots of spacedust, and swirrel it all togethor till a start ignights and the surplus becomes some planets
02:00 rue_house hmm
07:12 rumpelstiltskin morning pals
10:22 MrCurious https://www.youtube.com/watch?v=xZ0aksbiiXw
10:45 rumpelstiltskin :)
10:46 rumpelstiltskin MrCurious: the clip about russian disney characters I posted a week ago
10:46 rumpelstiltskin and you come back with it to me :)
11:55 MrCurious hahahahaha
12:19 rumpelstiltskin :)
16:03 ahmadexp check this out https://www.kickstarter.com/projects/494937902/arduimu-v4-an-arduino-based-integrated-measurement
16:14 GargantuaSauce lol 60 bucks?
17:18 deshipu brilliant
17:19 deshipu I just fried 7 servos
17:19 deshipu by connecting the battery wrong
17:19 GargantuaSauce whoopsie
17:19 deshipu for some reason board and one servo survived
17:20 deshipu I hope the battery is fine
17:20 GargantuaSauce get some big schottkys, .3V drop is acceptable if it means you can't fuck up like that
17:20 Tom_itx use keyed plugs
17:21 GargantuaSauce a fuse might have saved you also
17:21 deshipu yeah, I would need to make a pcb for that then
17:22 deshipu right now I just use this http://letsmakerobots.com/files/field_primary_image/IMG_20140908_194540.jpg
17:22 deshipu (there is a Pro Mini on the bottom)
17:22 GargantuaSauce neat, that is surprisingly compact
17:23 deshipu yeah, it has to fit in like 4cm×4cm×2cm box
17:23 rue_mohr2 hah, thats even better!
17:23 deshipu with the battery
17:23 rue_mohr2 ghood improvement
17:25 deshipu anyways, just wanted to share my misery with you guys
17:25 deshipu I know I had it coming
17:25 rue_mohr2 sweet, thanks
17:25 rue_mohr2 did you see how I did?
17:25 deshipu rue_mohr2: what did you do?
17:26 rue_mohr2 :( no pic with controller,
17:26 rue_mohr2 arg
17:26 rue_mohr2 http://ruemohr.org/~ircjunk/robots/arm8/slide.htm
17:26 rue_mohr2 I based the controller on what you were talking about at the time, as I'm using simular boards
17:27 GargantuaSauce your slideshow desperately needs controls
17:27 GargantuaSauce also images that aren't tiny :(
17:27 rue_mohr2 640x480 is more than enough detail
17:28 deshipu rue_mohr2: can you link directly to the relevant picture?
17:28 rue_mohr2 I need to get a pic of that controller, deshipu you gonna be around a few more hours?
17:28 rue_mohr2 deshipu, its not ther,e I have to take and post it
17:28 deshipu rue_mohr2: no, I'm going to bed soon
17:28 GargantuaSauce nobody will ever need more than 640k
17:28 deshipu rue_mohr2: I will see it tomorrow, I guess
17:29 rue_mohr2 deshipu, come tommorow
17:29 deshipu by the way, I found some battery charger ICs that can handle 2s
17:29 deshipu so I guess I will be making my own board after all
17:30 deshipu (microcontroller, regulator, charger and accelerometer is enough to justify it)
20:35 rue_shop3 hmm I dont think my appointment is gonna show
23:32 rue_mohr2 *sigh* well
23:33 rue_mohr2 close enough to bedtime I suppose
