This document will guide you through building and assembling your SquishBox. The "Soldering"
section describes how to assemble all the components included in your kit. To complete your
SquishBox, however, you will also need:
•
A Raspberry Pi computer (model 3B+ recommended)
•
An SD card (4GB minimum, 32GB maximum)
•
An AC adapter (5V or 9V, your choice - see below for details)
You'll also need an enclosure - a sturdy box to hold and protect all the components. The "Enclosure"
section describes how to prepare and mount your kit in a
it was designed, but you can adapt it to a different enclosure if you prefer.
You have the option to assemble your kit as a 5V-powered unit, which is the standard power supply
voltage the Raspberry Pi uses, or as a 9V unit by adding a couple capacitors and an LM7805 voltage
regulator that brings the voltage back down to 5V. Many effects pedal units run on 9V, so the 9V
version is useful if you plan to use your SquishBox in a pedalboard setup with many pedals sharing the
same power supply. However, you must provide heat sinking for the LM7805 - either by connecting it
to your metal enclosure using the included thermal pad, or attaching your own metal heat sink. Without
heat sinking, the LM7805 will overheat, lose power and cause the SquishBox to shut down. Plugging
multiple USB devices with high current demands into the USB ports may also cause the LM7805 to
overheat. If you build the 5V version you can discard the capacitors and LM7805 and skip the steps
related to the 9V build. Your choice isn't irrevocable - switching between 5V and 9V power is only a
matter of moving a couple wires.
