[Update 3/4/17 Looks like Shawn pulled the tDCS pages from his website. Though it’s still available via WebArchive. But the GitHub link is good.] A DIY tDCS project from Shawn Nock [Update 8/12/12 Shawn has updated his project to derive power via USB!]
The whole project (including all source files) was created with gEDA and friends and is published on github under a Creative Commons Attribution 3.0 License.
Practically speaking, this means that anyone interested in tdcs may (at their own risk): Download the designs, edit or modify them, fork their own design, and sell a product based on this design all without any proprietary (expensive) software.
Those who aren’t inclined to make changes, but want to experiment, can use the pcb design and the bill of materials to make small batches of devices for testing or personal use.
I’ve ordered the PCB’s and components, total cost for 3 sets (minus electrodes) is about $30.00. Will post an update after everything arrives and I solder it all up, probably early October.
Excellent JM! (But did you mean early December? lmk and I’ll correct it)
I downloaded and printed the circuit boards, but I need a list of components. I could quite read the one provided.
I updated the post. Shawn doesn’t seem to be involved with tDCS any longer, but it’s till on his GitHub page (link in post). Did you poke around in there for what you need?
