tDCS - zapping your Brain for Fun and Profit


tDCS wikipedia is basically applying a dc current across your skull. This is said to increase learning and reduce depression etc. if done right. Searching around on the internet (especially the subreddit) shows that building a tDCS device is actually simple - all you need is a battery and a L334M current stabilizing IC (and some resistors). Put this together with some sponge electrodes (can be constructed easily at least according to a source below) and you'll be able to stimulate your own brain.

Better learning/thinking, less depression by electricity across your brain? Sounds awesome! Let's do it because:

"Few things make you feel more irresponsible than relying on a subreddit for information on zapping your brain."[1]

There's a growing DIY community around tDCS - time to join in.

Project Log

User:Mihi has ordered some parts to play with tDCS --Mihi (Diskussion) 00:15, 12. Dez. 2013 (CET)

Parts have Arrived, unpacked and put in my box - was hacking campaigns not brains that night.... --Mihi (Diskussion) 09:13, 19. Dez. 2013 (CET)

Bought Sponges and Wire-mesh (pan cover) for the electrodes --Mihi (Diskussion) 17:54, 20. Dez. 2013 (CET)

First Session

Created a simple tDCS source- based on a LM334 (from the simple schematics directly linked below) Created a simple tDCS source- based on a LM334 (from the simple schematics directly linked below)
Constructed super cheap and simple electrodes out of stainless steel mesh and thin sponges (the sewing machine didn't like it - so I just squeezed it together). A super-simple sponge electrode

Not sure whether this makes me look smarter (or feel smarter)... Applying Electrodes

Created a simple DIY tDCS source - just breadboarded to try it out. Did a 15min session of 1mA (Anode around T3, Cathode above right eye) - except clear itching beneath the electrodes no marked effect that couldn't be placebo. Also Benutzer:Phantasus tried it out with the same itchy sensation. Let's see what happens if we do this more often... --Mihi (Diskussion) 23:57, 20. Dez. 2013 (CET)
