Smudge and Lorelei's Scratch Built Complete Helmet Electronics Adventure

Recommended Posts

Hello! I'm undertaking a helmet electronics project what I'd consider mostly from scratch (no components pre-wired together). I'm near-novice level; it's not that I've never wielded a soldering iron, it's just that the last time I did I was 12. Fortunately a good friend is an electrical engineer working in the field who can both explain things five times in a row AND lend a hand with stringing everything together. Phew.


THE CURRENT (lol, electrical jokes already) PLAN:

My voice changer will be a Teensy 3.2 coupled with the audio adapter shield and Bluetooth module as per TK Talkie's delightfully detailed V3 directions. A PJRC prop shield LC will act as amplifier for the little speakers which I'll be setting in my hovi mic tips. I'll have [many] helmet fans ('cause I'm here for a good time, not a sweaty time) on an independent circuit to cut down on electrical noise within my audio system, most likely powered by a rechargeable USB battery. I'll experiment with lavalier microphones behind my neck seal, and will probably integrate a hearing assist system down the road. 


Disclaimer: this project is in between invention and re-inventing the wheel. People sell similar pre-built components and systems! I've just been spoiling for an electronics project so I want to do it all myself.


This promises to be quite the adventure for my ANH stunt bucket Smudge and me. Come along, if you dare.
