Re: How to redesign a panel without any source files or information

i use graph paper, make a rough guess and draw it out, and then literally place the pots/knobs/switches/jacks on the paper to see if everything fits, and adjust where it's too close.

Re: Buchla Random Voltage Source - Convert to Eurorack?

i have PCBs available for this: http://fluxmonkey.com/fluxmerch_buchla.htm. it runs fine on 12v without changes. the outputs swing close to the rail, though - i usually build mine with attenuators on the panel for each out, or voltage dividers behind the panel to bring them down to a more reasonable...

Re: [AVAILABLE] Fourses Tarp PCBs

rather pleased with how this one came out... 3-way range switches, 2-input passive mixer to the 386 amp. gonna replace one of the mixer ins w/ a passive tone control (LPF-ish). it's gnarly.

Re: Tutorial for moving from DIY PCBs to commercial PCBs for first time

I've only ever used EAGLE to the former end - creating artwork for a laser print - and know nothing of the additional steps necessaery for, or expectations of, a PCB fab house.

Awesome, thanks. I was thinking of building this and didn't fancy it on a paper circuit. It looks like you've corrected the mistake on the paper circuit as well. :tu: I've ordered two to make a double tarp, maybe with a shmance instead of the eight knobs. mistake?? :? only Allah is perfect :hail:

Re: Using FPD for paper drilling template?

I print 2 copies: one glue on w/ rubber cement to use as a drill guide, then i strip that off and use spray adhesive (scotch77) to glue on the final paperface copy. i also often use a self-adhesive laminate sheet, with the top/bottom wrapped around and behind the panel.
