I sold out of my first batch of SquishBoxes that I built using standard [perfboard](https://youtu.be/3N3ApzmyjzE), so I decided to get serious and print some PCBs. This will make the next batch of SquishBoxes a bit sturdier (and less expensive, since I can put them together more quickly and with less parts), and also lets me offer the SquishBox as a kit for the more DIY-inclined (Pi, enclosure, PSU not included). I also designed the PCBs for the other two products I plan to offer - the [MidiFoot](http://geekfunklabs.com/hardware/midifoot/) and [StompByte](http://geekfunklabs.com/2020/10/08/new-thing-stompbyte/).



I got three copies of my first SquishBox PCB design from [OSHPark](http://oshpark.com) and put a test unit together, which you can see in the gallery below. I tweaked the design a bit after this, adding some edge solder pads, optional 9V->5V power regulation (response to a user request), and got artistic with the location of the vias. Should have some more complete units, plus kits and some new toys available in the [Tindie store](https://www.tindie.com/stores/albedozero/) within the next couple months!

  LCD works (loose wires are for DC jack)
