07:46 AM polprog: id go with a comparator as well, and a 10k trimpot between Vcc and gnd to adjust the sense level

10:25 AM rue_mohr: I did a casting copy of a clamp and it came out ok
10:50 AM Tom_L: gettin better
10:53 AM rue_mohr: I have a 3d printed frame I'll try to use as a template for another one

02:57 PM rue_mohr: :D
04:14 PM aandrew: rue_mohr: with the right (non-burdened) CT you can increase the burden resistor to develop a higher voltage and even potentially power itself...
04:15 PM aandrew: wow nice clamp
04:16 PM rue_mohr: thanks
04:16 PM rue_mohr: ok, Y axis motor is welded on
04:18 PM aandrew: ... serial port enthusiast?
04:18 PM aandrew: oh it's a shoutout to you
04:18 PM aandrew: right on
04:18 PM rue_mohr: he did my thing with the serial audio
04:18 PM rue_mohr: he just didn't feel comfortable playing the song by lookmumnocomputer
04:30 PM aandrew: your idea reminds me a little bit about how they got digitized speech to happen on the C64: they manipulated the volume register to modulate the sound instead of trying to actually play digitized sound the normal way
05:09 PM rue_shop2: the rc filter makes it a lot better, give it a try sometime!
07:52 PM rue_mohr: ok, I'm gonna rest for a min, then try to cast two more clamps
08:08 PM Tom_L: you need clamps?
08:08 PM rue_mohr: buckets of them
08:08 PM rue_mohr: well, 1 bucket of them would do me
08:09 PM Tom_L: turned out pretty good
08:09 PM rue_mohr: I'm happy, I have two more I want to try tonight
09:47 PM rue_shop2: ok, castings done, waiting for them to cool
09:47 PM rue_shop2: might have poured them too hot, shrinkage might not be minor
10:40 PM rue_shop2: ... the pattern shifted
10:40 PM rue_shop2: that never happens
