Upverter is an online platform that allows for electronics to be designed, parted, and built. As I understand it, once the design is fixed, you shop for parts – inside of Upverter, and then submit your project (to Upverter’s Chinese partners) to be built. I’d mentioned Upverter on the tDCS subReddit a few times. I was hoping to pique the curiosity of the engineer types that had designed and built their own tDCS devices… Crowdsource the design, and then anyone can order one!
What happened was I got an email from Eric Evenchick, a ‘customer success / hardware engineer person’ at Upverter! Eric had seen my post and written to help. He waived the team fee, set up the project and ported the OpenStim Arduino-based tDCS design, by ohsnapitsnathan (Reddit handle).
I hope I didn’t step on any toes by collecting these schematics to one place. I wanted engineers to be able to see quickly how other designers have thought about building their devices. If you’re an engineer type interested in tDCS please join our Upverter team.
It feels silly to put it this way, when the very nature of Open implies extreme democracy, but here goes… Here’s my vision of an Open tDCS project.
- Build an Upverter team
- Design, part, and prototype a minimum viable tDCS device
- Working with an online ‘cognitive test’ site, build a protocol for measuring the effectiveness of tDCS
Later on we could develop a multi-channel device, and maybe this is just a fantasy, but if it could interact with the internet, researchers could design tests and collect data non-locally. How cool would that be?
I called this one Imgur earlier on the blog. It comes from 55tfg7879fe42e345 (Reddit handle)
Shawn Nock has 3 different designs. This was his first and is the simplest. (And I just realized he housed his designs on GitHub under the ‘Open tDCS’ moniker.)

If you know of a schematic I missed please let me know, and even if you’re not an engineer, consider joining Upverter and ‘Following’ our project.
