Great progress. I would like to speak to you via email. I would like to test your TDCs device on myself while at the piano. I am a musician. I am curious to see the effect on my learning ability as well as on my creativity. I will build the device, but could use some direction. Please email me. email@example.com
ryan,what parts of your brain would you plan to stimulate (and with what relative charge)
Shouldn't the ammeter be after the LM 334 and resistors?
