Just for Fun: tDCS in a Bottle

If you have been reading my blog, you know that I have built a number of tDCS devices – from the simple to the complex. All do basically the same thing – deliver a very low current for the purpose of various tDCS treatments. I mentioned in my last post that Keith Spaulding of http://dcstim.blogspot.com has come up with what must be the simple tDCS design of the decade. It works, too! Keith plans to market a line of tDCS devices and I’ll review his first in my next post.

I decided to borrow Keith’s design one more time and build a simple tDCS device into an old pill bottle, just to show how easy it is to build a current regulated tDCS device – and to show how small they can be. My latest creation could easily be carried in a pocket or tucked in a hat. I call it “tDCS in a Bottle” and yes – I decided to copyright the name – hey why not?

My simple circuit consists of a type 23A 12v volt battery, a 2.2 k Ohm resistor, a current regulating diode (CRD), a pill bottle, and some lead wires. You could build one yourself in 15 minutes or less!

(Wired and tested tDCS components ready to stuff in a pill bottle. Yes, I did peel the old labels off of the bottle.)

(Closed up, ready for new labels. Small, very portable, works!)

After I completed construction, I checked regulated current output with a DVM – and plan to do so periodically to verify battery condition.

It’s sort of an ironic twist to build a tDCS device into a pill bottle – just think how many people might be able to get off of pills if tDCS were in wide use by the medical community! Wow! Anyway – “tDCS in a Bottle” works and works well – delivering a current regulated 1, 1.5, or 2 mA depending on which CRD is used.

If anyone is interested in partnering to sell these at the check-out at Walmart, let me know. We could do the country a lot of good! Pharma would not be happy. Think the FDA would be ok with it? 🙂

  2. I think your idea of helping people gain the benefits of tDCS is laudable. However, getting the FDA’s approval to sell this at wal-mart (or anywhere else for that matter) is virtually out of the question. The only way is to use a “work around” or a loop hole that doesnt involve getting FDA consent.
