Thread: Dramatic improvement in dream recall

I agree it is not conclusive, I will continue using the device and I will post any progress or regress when it occurs. I have done memory stimulation yesterday and remembered a long and vivid dream that night, again no conclusions there this is what happened, it may be coincident that I want to remember them and since I use device I subconsciously make myself to do so "placebo" either way I am happy it works

Hi FateTrader.

Your tDCS experiments seem fascinating although I would always proceed with caution and to not 'over use' such a home made device in a session or to use sensible breaks between sessions and frequency of usage over time.
I apologize that I haven't had chance to view the many links. I guess one of those articles would answer usage times and recommended frequency of use (for safety.)

I too am quite interested in brain states and dreaming too. I did download a schematic (last year) that I sort of recognise on the main link you have posted.

I was a bit coy at making one and trying it out however!

My device is powered with two 9V batteries in series it gives 18V and it uses 1x 4k7 resistor 1x 5k switched potentiometer and 1x 0-20 mA ammeter.

I have checked your YouTube video (via Schematics 1. My tDCS device.)

Here are some of my concerns:

1. Simple should not mean cutting corners (see fuse note.)
2. If a person who builds the circuit has no electronics knowledge then he should always have his or her circuit checked over by someone who has knowledge like an electrical/electronic student or engineer preferably.
(It is always best to err on the side of caution.)

I.e: In the video you are hooked up to a single 9v battery with different resistors, etc. although you are using a current limiting semiconductor, etc.
However You have no fast-blowing fuse in the anode lead (from what I can see.) That is a safety issue!

Good luck and stay safe!

EDIT: Technically you have a built in protection fuse in the in-line Ammeter (200 mA?) which would still be far too high though.
