I’ve now built another 3 of the PCBs and daisy chained them.
So the power comes from the first and is fed into the others (there’s two sets of power pins on the PCB for this reason. Also the gate from the top feeds into the next, and so on. So one gate can trigger all four, or you can have two gates triggering two EGs and so on.
Next step is to get the front panels made. I’ll probably make a few of these, so if anyone is interested in buying a front panel and spinning their own PCBs for it let me now.
I plan on having two of these quad EGs in my system.
