Tasty wee project. I have built a couple of arduino based desktop granular synths and was going to build the next one in euro rack format. This is a tidy implementation.

Thanks! The MCU is just an Arduino clone. The sounds are actually coming from my analog oscillator. Adam's card is doing the sequencing. :)

Your panels look amazing! I love the hand drawn look on the silkscreen. Are you using any plugins to go from Inkscape to Kicad? I'm interested in your work flow. I can make functioning pcbs but they look nothing like yours!!
@benjiaomodular12 күн бұрын
Hey, thank you so much! I don't use any plugins to do this. My workflow right now is: 1. Do a rough layout of the controls on KiCAD's PCB editor 2. Export as SVG 3. Import SVG into Inkscape 4. Draw my labels and refine the layout (alignment, etc.), using the SVG as a guide 5. Remove guide elements 6. Export to PNG 7. Import into KiCAD through the Image Converter as a Silkscreen footprint 8. Finalize PCB layout 9. Export Gerber...

@benjiaomodular15 күн бұрын
Thanks! Good question, I guess it's just a leftover from when I built my modules for a single 9V supply. You'll probably be better off connecting it to vcc-, just have to test it.

… or is there enough room to simply offset them from the hole? You wouldn’t have a direct light dead center but more diffused… or maybe it would be too diffused? I’m not sure how much complexity would be added to the board mounting on the back. I’m interested in seeing where you land with this!

yup!! i was also curious about that. keeping them in the front would definitely be ideal for me. i'll try some stuff out and report back. :D

UPDATE: i tried to hack something together, some of the metal parts in the socket mechanism were blocking the light from shining through. there has to be a sweet spot..
@RandomMakingEncountersАй бұрын
Yeah... I'm looking at a Thonkiconn right now and there's a flat strip that is where the tip of the plug connects. It would need to be opposite that almost next to the pin... hmmmmm. I'm not sure how small those smd LEDs are but that's looking pretty tight! If you could get it to work, that bit o' metal would make a nice reflector for the light!! LOL!
@benjiaomodularАй бұрын
@RandomMakingEncounters i know, right? I'm already probably using that piece of metal as a reflector the way I have it now. I could nudge the LED closer to the pin, but that same piece of metal kinda pushes the jack towards that direction which makes it a bit sketchy. I'll play around with positioning a bit more I might end up just mounting the LED upside down from the back through a hole.
