I’m waiting for build feedback (no pun intended) on the first batch of purchased pi-Stomp bundles. I’ve received a few questions, so I’ve been updating the build instructions to clarify certain steps. Once I’ve heard that a few more units are up and running, I’ll submit an order for new boards (likely with some minor …

3 more orders getting ready to ship.
Four prototypes which led to the first release
Almost 1.5 years from the original idea and after 5 circuit board prototypes, 4 different enclosure prototypes with 2 machine shops taking my order then closing due to economy/Covid. We’re now stocked with 35 enclosures, and parts bundles. Mouser.com seems fully stocked with the other “half” of the parts. The website, store, wiki and github …
Like most everyone these days, my priorities have changed. As I wait for parts to be restocked and my enclosures to be machined, I’ve embarked on a redesign of the true-bypass relay system. Each pi-Stomp! has included 4 SPST reed relays. 14 of the first 16 used worked just fine, two were not switching. Eventually …
I had sent off my enclosure CAD specifications for manufacturing. Parts were ordered. pi-Stomp software nearing v1 completion goals. 3 builds complete by me, along with a successful build by a friend using only the wiki instructions. Website/Store was taking shape. I was nearly ready to go public. Then Covid struck. I won’t even compare …
New build, new board with a few improvements Swapped location of Left and Right jacks (more intuitive) improved signal routing to minimize noise Slight location tweaks to facilitate mounting in enclosure Improved part labels
Monumental day. All major hardware functionality works! Audio processed thru both Left and Right channels Headphone output works Bypass relays controllable via footswitch LCD shows current Pedalboard / Preset / Tweak param / Tweak value / footswitch mappings and enable state Each footswitch sends MIDI CC and toggles LED ring Tweak Knob sends MIDI CC …
Mod software running on Raspberry pi (not shown) Control board with encoder to select pedalboard/preset plus two parameter tweak knobs Arduino for sending MIDI CC to pi via USB with input from tweak knobs, expression pedal and DIN MIDI jack 24-bit/48khz audio card (blue board) Dual gang volume pot Two true bypass switches for R …
