Boards, sound, apps and sites that work.
We design circuit boards and the sound software that runs on them, build apps that keep working offline, and make websites and shops for businesses that want more customers.

What we’re aiming for
Things you can use, and trust.
- Play with itWhere we can, the work is something you can try in the page: a tuner, a guitar rig, charts you can tilt.
- Open to everyoneKeyboard, screen reader, reduced motion and plain-text versions come first, not last.
- Yours to keepWork that keeps running offline and stays in your own hands, with no account to lose.
- MeasuredBoards and sound you can measure, with the numbers published, misses included.

Boards
From the file to the factory.
Circuit boards we design in code, check by machine and send to a real factory. The three pedal kits are not for sale yet.
PhotoMeasuredRenderInteractiveTwelve boards, zero design-rule errors.
Every board we have designed, checked by machine.
RenderTRAIL OD, an overdrive pedal kit.
Soft, diode-clipped drive you build yourself.
RenderCLAW, a distortion pedal kit.
Hard clipping you build yourself.
RenderGOLDFOOT, a transparent overdrive kit.
A clean blend keeps your own tone on top.
RenderStomp 125B, a digital pedal board.
The main board of our pedal platform.
RenderA headphone amplifier.
A small analog board with the Squatch on it.
Renderswitchbridge, four switch inputs for about $2.44 of parts.
A small USB box for people who can't use a touchscreen.
RenderAn enclosure, checked before it is cut.
A pedal enclosure modelled as an object.
MeasuredDrawingSchematics match their boards, 10 of 10.
Sheets drawn so a person can read them.
RenderThockfoot.

Sound
Sound you can measure.
A tuner, a guitar rig, a tab editor and a sound engine, with the numbers behind them.
LiveCaptureInteractiveThe tuner locks in 44 ms.
A guitar tuner for your browser and the pedal.
LiveInteractiveSquatch Rig.
A whole guitar rig on a web page: amps, pedals and a cabinet.
CaptureThe pedal's own app.
An iPhone app for routing, settings and tuning.
MeasuredCaptureInteractiveA circuit model held to its reference.
Our sound models, compared against a circuit simulator.
Measured
The number that didn't hold up.
Where the same model is off by 9.5 dB.
LiveCaptureInteractiveThe DSP engine.
One small library of sound blocks: gate, EQ, limiter, cabinet and tuner.
CaptureCaptureThe Squatch plug-ins.
Ten effects for your DAW, as Audio Unit, VST3 and CLAP.

Apps
Apps that keep working when the network doesn't.
A home hub, a setup page and a room scanner.
Sites and products
Sites that get you found, and products of our own.
Our own site and shop, a pet-adoption search, an assistant-ready server and a grammar puzzle: the same kind of thing we build for others.
Capturesquatch.cc, our own website.
Hours, tap-to-call and a way to reach us at midnight.
LiveOur shop.
Real goods with the Squatch on them.
LivePetnecto, an adoptable-pet search.

LiveSquatch Stack MCP, tools for your assistant.
A public server that any assistant able to use MCP can connect to.
The full list
Everything we’ve done.
Smaller jobs, experiments and firmware, in one plain list.
- Six radios, run on real hardwareZigbee, Z-Wave, Thread, Matter, Wi-Fi and Bluetooth LE have all been run on real devices, not only in simulators.
- Our own device in Apple HomeAn ESP32-C6 we programmed joins a home's Thread mesh and appears in Apple Home as a Matter device.
- Updates that can't brick a deviceOur update guard rolls back any failed over-the-air update: 698 of 698 fault-injection cycles passed.
- A Zigbee device built from scratchAn ESP32-C6 Zigbee light joined our hub as a mesh router and was controlled from our own software.
- Presence sensing with a radarA 24 GHz mmWave radar feeds presence and "resting on the couch" detection in a real home.
- Sixty renders of our boardsFive views of every board, 60 renders in all, straight out of the design files.
Accessibility
Built so everyone can use it.
This site
Every page is checked with an automated tester and by keyboard. A skip link comes first, every control can be reached and shows where you are, and motion stops when your device asks for less.
Live pieces
Each live chart and 3D scan comes with a text version and a plain picture to fall back on, so nothing depends on a graphics card.
Hardware
switchbridge is a four-input switch box for people who can’t use a touchscreen.
