12:12 AM rue_mohr: yup, code was using wrong pins
12:15 AM rue_mohr: little bit more electrical noise int eh built pendant, causes a bit of 'noise' on the step signals
02:15 AM Jak_o_Shadows: rue, it's a stm32f103c8t6 - but the code is correct, it works on a different board I have.
02:15 AM Jak_o_Shadows: But still, weekend job
02:56 AM Jak_o_Shadows: Hmm. How am I going to stack these protoboards
02:57 AM Jak_o_Shadows: The corner holes are about 2mm
02:58 AM Jak_o_Shadows: Hmm. Pity I don't have a tablesaw
04:09 AM Jak_o_Shadows: may need more mofsets
04:10 AM Jak_o_Shadows: but hey, it seems like it might be reasonably effective
04:10 AM Jak_o_Shadows: like, neat
07:00 AM Jak_o_Shadows: hmm. I could feasibly put optocouplers into this christmas lights controller boards
07:00 AM Jak_o_Shadows: Probably not in time for christmas though
09:28 AM rue_mohr: Jak_o_Shadows, external 32.768Khz crystal?
09:28 AM rue_mohr: carefull, the 32.000 Hz ones look the same
02:43 PM SpeedEvil: https://i.imgur.com/lKyzXvz.jpg?1 Soak testing my new arm with 5kg water.
02:43 PM SpeedEvil: Alas, unpowered
03:16 PM weyland|yutani: SpeedEvil, whats the purpose of this test?
03:18 PM SpeedEvil: To see if it sags if it does not and still works, it gets a monitor on it, after a little more testing
05:17 PM robotustra: wooden robot leg?
05:20 PM deshipu: arr, shiver me timbers
06:35 PM SpeedEvil: The joints seem to work adequately, though with high friction, I need to eat several more of the ready-meals which have a nice slippery PE lid.
07:21 PM veverak: https://imgur.com/a/Id5fX
07:21 PM veverak: it is spinning
07:36 PM SpeedEvil: yay
07:37 PM SpeedEvil: Is that intended to be more decorative than functional, or is it an actual boat
07:43 PM robotustra: got metal finally https://imgur.com/KGCivjv
07:47 PM SpeedEvil: yay
08:12 PM veverak: SpeedEvil: is going to be functional
08:29 PM robotustra: you will put plates in it?
08:31 PM SpeedEvil: veverak: it looks extraordinarily top heavy
08:34 PM robotustra: it's plastic, the density of plastic is about 1 g/cm^3
08:34 PM robotustra: and there are plenty of holes in it
08:34 PM robotustra: and yo don't know the infill
08:37 PM SpeedEvil: hmm
08:37 PM SpeedEvil: true
08:38 PM veverak: robotustra: yep
08:39 PM veverak: it is too big to be honest
08:39 PM veverak: 60mm radius
08:39 PM veverak: next version is going to be 40mm radius
09:11 PM Jak_o_Shadows: Yeah rue, the external 32.768kHz.
