Built a box yesterday but messed up the circuit while putting it on a proto-board - know the bug will fix, test and post pictures... --[[Benutzer:Mihi|Mihi]] ([[Benutzer Diskussion:Mihi|Diskussion]]) 18:04, 22.

===Second Session=== | |||
Finished the box and fixed the bug in the circuit. Tested it (also with an external ampere meter.) - See notes on testing below. Ran a second session of 15minutes 1mA. (same montage as before). --[[Benutzer:Mihi|Mihi]] ([[Benutzer Diskussion:Mihi|Diskussion]]) 11:44, 23. Dez. 2013 (CET) | |||

== Notes on Testing DIY tDCS Devices == | |||
Since you're building this on your own you might want to make sure the device works as expected. I test my device using: | |||
* A range of resistors <1KOhm | |||
* An external ampere meter. | |||
I put the resistor and the ampere meter (serially) to where my head would be in the circuit then fire it up. I make sure the current is properly adjustable and the meter I have is the same as the external ampere meter. I switch resistors and try again. | |||
Only after doing this I can be sure that the current is properly limited by the LM334 circuit. | |||

non-research and non-therapeutic objectives by lay people." | |||
