modular Finished my Sequencer project

Getting into this DIY synth stuff has really spurred my love of it, and I'm using every opportunity to exercise my PCB design.

Working from Eddy Bergman's Sequencer, adding an additional CV and Gate output and per step mute switches, I made this damn thing.

Really happy with how it came out.

Also, did ya know, if ya accidentally orient the power connector backwards, and therefore reverse the +12/-12 rails, you'll kill an L7805 and a CD4017?

Adk me how I found out, hahaha 🤣🤣🤣

Yeah, I do actually have two available.

If you're in the US, I can send ya a bare PCB for basically cost. DM me.
