I finally started a project that I’ve been talking about for a long time, and it just seemed fitting to call them Tweedle-Dee and Tweedle-Dum.

Tweedle-Dee is an Arduino Mega2560 with an NRF24Lo1 radio module. He will receive a unique, constantly changing code (provided by the Google Authentication service) sent from my phone. Upon receiving the code, Tweedle-Dee will parse a value that follows it that is the number of seconds that the front door should be unlocked. Using the NRF24L01 radio, an encrypted message containing authentication information and the time to remain unlocked will be sent from Tweedle-Dee to Tweedle-Dum.

Tweedle-Dum was originally constructed with a Teensy 3.1, which doesn’t seem to have the juice to power the NRF24L01 radio module effectively. I should be receiving the replacement MEGA2560 tonight, and I will update when I get the wireless communication between the two working.

Other Updates

I have uploaded some more research/white papers on tDCS under the project references -> tDCS page. Feel free to have a look, and if you know of any more, please let me know!
