Open Source Assistive Devices and Possibly Inspirational Stories.
In partnership with American Legion Post 468
An autistic-stim variation of the V3 hardware.
Hardware is laid out. PCBs are on the way. Plastics are designed. The next step is a Build A Stim Device set of instructions so anyone can put one together for someone who needs one.
The Autism Stim variation shares the V3 core electronics. Here’s what’s already done and what’s next.
The PCB design for the Autism Stim variant of the V3 hardware is finished.
The colorful enclosure shown above is rendered from the production CAD files.
A first batch of boards has been ordered for testing. Once they’re in we’ll build the first units.
We’ll publish a complete, open-source set of build instructions so anyone can assemble one for the person in front of them.
Four large, satisfying stim pads around a small color screen. The same V3 core electronics that runs our communication devices, reshaped around sensory input and play. Configurable through a plain text file on a USB drive — no reflashing, no IDE.
It’s an educational toy first, an AAC tool second, and a budget for the larger project: every dollar that goes through the stim devices helps fund building communication devices for people who can’t ask for one.
Working with American Legion Post 468 (Julian, CA), we’re running a charity build of 30-50 units to go to autistic kids and the families that support them. The Legion handles the paperwork — the part we’re bad at — so every dollar lands where it’s needed.

Every dollar goes into parts and devices. American Legion Post 468 (Julian, CA) handles the processing — we just build.
Sponsorships are processed by our partner American Legion Post 468 (Julian, CA). They handle the paperwork — the part we’re bad at — and every dollar lands on parts, PCBs, and the next batch of devices.
If you’d rather support the broader project (not just the stim batch), these go directly to T-Rex / TSSFAA.
