[00:05:52] <rue_house> ohohohohohohohoh I got an idea
[00:05:54] <rue_house> I'm the first
[00:05:56] <rue_house> okokokokok
[00:06:00] <rue_house> its a POV clock
[00:06:04] <rue_house> BUT IT DOSN'T MOVE
[00:06:13] <rue_house> there are two lines of leds
[00:06:20] <rue_house> one vert, one horiz
[00:06:37] <rue_house> the horiz one chases as a speed ref, the POV is on the vert set
[00:07:00] <rue_house> you follow the horiz with your eyes and while doing so, should be able to read the POV on the vert leds
[00:07:16] <rue_house> IS THAT GREAT!? IS IT??? IS ITTTT!!!?!?!??!?!
[00:07:28] <rue_house> CMON, YOU HAVE TO SAY THATS COOL
[00:09:01] <rue_house> I'm the last one alive int eh world arn't I?
[00:09:06] <Jak_o_Shadows> no
[00:09:17] <rue_house> I must be close
[00:09:34] <mrdata> not while i'm still around
[00:09:37] <Jak_o_Shadows> cannot confirm or deny that one
[00:10:10] <mrdata> but it is my bed time
[00:10:19] <rue_house> I'm gonna die alone...
[00:11:49] <Jak_o_Shadows> well, thats hopefully not going to be soon, the dieing part
[00:12:00] <Jak_o_Shadows> how close is your stm32 boards from arriving? A fortnight or so
[00:12:03] <Jak_o_Shadows> ?
[00:42:13] <rue_shop3> no idea, postal strike comming up
[00:57:31] <Jak_o_Shadows> :(
[01:10:29] <rue_bed> for what its worth, I did install the compiler, uploader, and compiled the flashing example
[01:10:54] <rue_bed> I think I was able to find the right example of how to use the uploader
[01:10:59] <rue_bed> so, its ready
[01:11:19] <Jak_o_Shadows> what library/package are you using?
[01:11:27] <rue_bed> see if I accidently kill them all by inadvertantly pushing 5V into them
[01:11:31] <Jak_o_Shadows> (yeah, mine has been steadily blinking for the last 2 days)
[01:11:35] <rue_bed> huh, cant remmeber
[01:11:42] <rue_bed> I followed the makefile
[01:12:18] <Jak_o_Shadows> huh. I found getting the correct Makefile and linker script half the challenge
[01:12:49] <rue_bed> arm-none-eabi-gcc
[01:13:06] <Jak_o_Shadows> ah. yep. I'm using the libopencm3 library rather than the one stm provides
[01:13:09] <rue_bed> I just got what the makefile used
[01:13:26] <rue_bed> I remember when avrs were like this
[01:13:50] <Jak_o_Shadows> fragmented
[01:13:51] <rue_bed> the library I have is really basic
[01:13:52] <Jak_o_Shadows> ?
[01:14:21] <rue_bed> I mean, I could be writing for a 8041 and not notice much difference
[01:14:48] <Jak_o_Shadows> except in details :P
[01:14:50] <rue_bed> then came prycon avrlib
[01:15:01] <rue_bed> avr libc
[01:15:44] <rue_bed> I'm mainly interested in a platform to move to when avr goes away
[01:15:55] <rue_bed> which I'm sure microchip will do
[01:16:12] <rue_bed> the only delay I can see is from china knockoffs
[01:16:21] <rue_bed> but china has their own contnrollers they like to use
[01:19:02] <rue_bed> I dont use much in the way of libraries anyhow
[01:19:16] <rue_bed> I have a set of macros for bit manipulation,
[01:19:28] <rue_bed> I have some delay, adc, and serial functions
[01:20:09] <rue_bed> Jak_o_Shadows, I'm gonna be interested to see just how fast they are
[01:20:37] <rue_bed> they aren't 1 cycle as I understand, so I dont expect them to specifically be faster than a 16 or 20Mhz avr
[01:20:55] <Jak_o_Shadows> I'm interested in having a common platform
[01:21:04] <rue_bed> if instructions are 4-6 cycles, they are the same speed as the avrs
[01:21:12] <Jak_o_Shadows> The nicer ones, the cortex-m4 ones, have hardware floating point
[01:21:26] <Jak_o_Shadows> Something something thumb mode something something
[01:21:40] <rue_bed> I think arm is gonna be the processor used in everything soon enough
[01:22:25] <rue_bed> cause I think the big intel and amd chips days are limited, mainly cause of them trying to lock down 'unauthorized code' (aka, not windows)
[01:23:10] <rue_bed> the arch of a pc has become pretty ugly
[01:25:44] <rue_bed> I realized that I might be able to use that stm for my digital scope
[01:25:59] <rue_bed> I have a 20Msps adc it might be able to drive directly
[01:26:11] <rue_bed> THAT would be cool
[01:29:11] <Snert> encrypted instruction sets where you buy a key :(
[01:29:44] <Snert> just around the corner I bet.
[01:34:53] <rue_bed> anyhow
[01:35:04] <rue_bed> I think arm will just propigate to everything
[01:42:19] <Jak_o_Shadows> Did ON semiconductor buy out part of micron at some point in th epast?
[01:42:56] <Jak_o_Shadows> Cause trying to find a camera that has a breakout board, but the chip itself is still in active proudction....
[02:43:37] <bindigoat> future of robotics

[04:08:37] <newbie69> rue_bed: are you awake?
[09:16:24] <rue_house> new...
[14:58:34] <deshipu> https://www.youtube.com/watch?v=0ZBD2tcKOU4 <-- muscles
[15:09:42] <mrdata> impressive
[15:21:09] <veverak> that's cool
[15:21:37] <deshipu> pretty pathetic, actually
[15:29:04] <veverak> nah
[15:29:06] <veverak> fu me
[15:29:10] <veverak> so for MQTT gui simple and easy
[15:29:16] <veverak> I can pick either node.js app or android app
[15:29:21] <veverak> I think I wil lstick to andorid
[16:31:47] <Snert> they strapped a bomb to a robot and sent it to take out the shooter.
[16:32:09] <Snert> guess that blows Asimov's law out of the water.
[16:36:18] <deshipu> forget asimov, that was a plot device, not a realistic proposal
[16:59:48] <Snert_> ya. "of own volition" was operative in his laws.
[17:00:17] <Snert_> I figure they coulda tried the gas cartridge first though. Maybe they did who knows.
[17:01:03] <anonnumberanon> Interesting how they did not use self-defense killing in that one.
[17:07:39] <anniepoo> anytbody know how these multifilament muscles work?
[17:08:28] <Snert_> you mean different from muscle wire? as in multi-strand?
[17:08:48] <anniepoo> in the video deshipu just posted
[17:11:20] <Snert_> maybe the wire insulation was white but I couldn't see the electrical wires.
[17:12:07] <anniepoo> is it pneumatic? electric? or something else?
[17:16:22] <Snert_> on 2nd view, there's too many wires going to the muscles so it has to be electrical.
[17:17:19] <anniepoo> https://www.youtube.com/watch?v=0rKMD3i7DMU - pneumatic
[17:17:21] <anniepoo> in the title
[17:17:56] <anniepoo> it's a very thin air muscle
[17:18:04] <anniepoo> see that video
[17:18:23] <deshipu> from the sound I'd guess pneumatic
[17:18:40] <deshipu> it's a dead end
[17:19:21] <anniepoo> funny, no sound on that last video I posted
[17:19:33] <anniepoo> why?
[17:19:37] <anniepoo> noise?
[18:35:43] <rue_house> maybe youtube ran out of space
[18:37:24] <rue_house> makes sense
[18:37:26] <Tom_itx> i thought space was infinite
[18:37:49] <rue_house> one of the limits on air muscles is the change is surface lentch for the single filament
[18:38:45] <rue_house> they are having fun with that, I wonder what their control system is like
[18:41:57] <rue_house> suddenly its gone from the world telling me I was stupid to try to make a robot with pneumaics to everyone doing it
[18:41:59] <rue_house> wtf!?
[18:46:02] <rue_house> if I hurry, I'll be the first to do counteracting servopneumatic muscles
[18:46:47] <Snert_> just shows to go ya, don't pay attention. Do what you will.
[18:47:01] <Snert_> it will work or it will not.
[19:17:51] <anniepoo> yup - just do what you're doing
[19:18:29] <anniepoo> at best you've won. At worst, you're in just the place you would have been if you did what everybody else did.
[19:24:37] <Snert_> keep in mind too that irc scare stories don't always mean it all.
[19:25:09] <Snert_> lofty conversations happen about matters that will never ever plague an innocent hobbyist.
[19:26:31] <Snert_> yet the noob sees all this and knee jerks his way into a situation that should never have occured
[19:31:42] <z64555> what I miss?
[19:46:15] <Snert_> nothing big.
[19:48:11] <z64555> that period is suspicious. :]
[19:49:02] <Tom_itx> it's a pinhole camera watching you
[21:35:59] <z64555> D:
