Hi everyone,

I've learned a lot on here in the last year or so of building DIY projects, and the next step for me is to start making my own boards, so I wanted to share a small project that I made.

I couldn't find something quite like this in Eurorack but I really needed it: a module with a simple passive bypass switch.

The obvious way to use it is to send/return and bypass the path of audio or CV through a module (like clicking a guitar pedal on or off), but what I really wanted it for is to also be able to re-patch while playing live without breaking and audio or CV signal. Patch one CV source to the "In" and while you're playing patch a second source to the "Return", and flick the switch to move from one to another. Then you're free to re-patch what's connected to "In" without disrupting the performance. A second switch allows you to keep the connection from "In" and "Send" always connected, for example if you wanted a delay effect to already be delaying the incoming audio before the "Return" is switched on.

It's too simple to really require a PCB, but like I said I wanted an easy project to learn how to lay one out smile

It's in 3hp which some might balk at, but all of my cases seem to be able to let me squeeze an odd number of units of HP per row, or otherwise just add two of them in a row to keep things even smile

From OSH Park you'll end up with 3 PCBs and panels for about $27. I couldn't decide on a panel design so the panel is reversible. One describes the connections, the other shows the connections through symbols.

BOM:
— Four Thonkiconn or Kobiconn jacks
— One DPDT On-On switch, like so:

— One SPDT On-On switch like so:

thanks for sharing your project with the community.

Oh sure, trying to show up my one DIY build:

waah waah waah

I often lurk around in here, marvelling at the amazing builds. I can't believe how talented you DIY guys are. I suck so bad, my hands shake, and I can't see shit.
Here's my one little project, I built them to make use of three vintage toggle switches I've had for years. They're very robust and can be pushed momentarily or locked down. I made three identical units out of 4HP Euro blanks. The top jack is connected to the middle or bottom jack depending on the switch position.

Important things to note:
I'm fucking blind and can't drill straight very frustrating
There's enough solder behind those babies for an entire Klee! very frustrating
