Recommendations for intermediate DIY builds?

#1

Anyone have and good recommendations for useful intermediate DIY builds?

So far I’ve done some basic stuff, including an APC from scratch following the synthrotek schematic, an op-amp based ADSR that’s currently on a bread board but works (I’m kind of dreading moving it in to pad per hole though), and a Braids from a BOM, which I haven’t programmed yet.

I guess I also want to DIY some buffered mults and maybe a slew limiter. I know I should finish what I’ve started before getting too deep with anyone else, but I’m gonna ask anyway: Anyone have any recommendations for useful, relatively simple modules (say, stuff based mostly on op-amps and other basic chips) that are fun to build?

This is the ADSR I’m building: http://electro-music.com/forum/topic-31473-50.html

If anyone knows of a good pad-per-hole, or PCB design for this or something similar, that would be lovely :joy:

Looks interesting, an adsr was next on my build list after I finish my Midi to CV module. I have a bunch of designs to send off to JLC PCB I’ll keep that design in mind (I make my layouts available via easy-eda) the midi to CV is relatively moderate.

Cool, keep me in the loop. Happy to buy a few PCBs, especially if you can get them done for cheaper 'cause of it.

JLC minimum is 10 so I usually have a few spare!

Righto, I’d definitely be up for 3-5. Do you already have a layout in mind?
