01:08 AM rue_bed2: - jan 6
01:48 AM Jak_o_Shadows: rue, I just turned off all the annoying parts/joins/quits/day change messages
02:59 AM Jak_o_Shadows: Can't get away from bloody NickServ though
03:16 AM Jak_o_Shadows: Also, the parts for the PCB's have started tricklign in
03:17 AM Jak_o_Shadows: I got a kit of 805 SMD resistors today
04:25 AM srk: gotta acquire bunch of these kits as well
04:26 AM srk: just ban the join/quit spammers :)
04:27 AM srk: but not the robots
04:28 AM Jak_o_Shadows: no, i'm one of the join/quit spammers
04:32 AM srk: you can use znc for persistance, running my on rpi currently
04:33 AM srk: or shell acount on some 24/7 running machine with screen/irssi
04:58 AM Jak_o_Shadows: Yeah, I normally do run a bouncer throughout the day
04:58 AM Jak_o_Shadows: just for reasons currently, it has to go off at night
04:58 AM Jak_o_Shadows: also, I use quassel, not znc
05:14 AM mrdata-- is now known as mrdata-
11:22 AM sorki is now known as srk
07:29 PM veverak: rue_mohr: that's me testing my PID controll 2am
07:29 PM veverak: ( https://twitter.com/SquirrelCZE/status/1347351261197299713?s=20 for the rest of the channel )
07:31 PM rue_mohr: oh, what are the motors then?
07:32 PM rue_mohr: its a strange stance
07:33 PM veverak: https://www.hiwonder.hk/products/hiwonder-lx-15d-serial-bus-servo
07:33 PM veverak: it should be "smart servo"
07:33 PM rue_mohr: and what are the status colours
07:33 PM veverak: so the PID should be inside and you just send a command
07:33 PM veverak: but the internal regulator is meh
07:34 PM veverak: (As, it won't output more power when servo needs it to push heavy htings, like the robot body)
07:34 PM veverak: rue_mohr: that's random
07:34 PM veverak: it has detection for stall/voltage/out_of_encoder_position errors
07:34 PM veverak: if that happens, it changes to corresponding color
07:35 PM rue_mohr: blue is ok?
07:35 PM rue_mohr: on my servos, I used 2 colour leds
07:35 PM rue_mohr: so I have off, yellow, green, red
07:36 PM veverak: blue is actually out of "known position"
07:37 PM veverak: manufacturer specifies that the angle is 0...1000
07:37 PM veverak: (0.24 degree per step)
07:37 PM veverak: but I found out that in reallity it is much "wider"
07:37 PM veverak: but the servo still blinks if you are outside the 0...1000 range
07:42 PM veverak: I think I have to change the design of the knee
07:42 PM veverak: now it may step on the wire there
07:42 PM veverak: it should not, but it's too close
08:17 PM rue_mohr: I have not re-addressed the overloads for my hexapod
08:21 PM veverak: man
08:21 PM veverak: I have to start to use gitlab issues
