P006: Electronics Etc.


A collection of some other electronics projects I’ve worked on over the years


P006.1 – Automated Hydroponics System

I designed and built an automated hydroponics system for growing plants, with control of lights and water temperature, and pumping of PH, NPK+micro nutrients. The system was built around a Teensy 3.5, using fuzzy logic to control the FSM. I successfully grew many things, including a full-sized squash indoors.

P006.2 – Cosmic Watch

I assembled and experimented with a set of 4 Cosmic Watch radiation detectors designed for detecting cosmic rays and evaluating incident energy. When set up in a coincidence measurement, primarily vertical cosmic rays can be discriminated from other sources of radiation.

P006.3 – Electric Bike

I designed and built my own electric bicycle, with a 4KW maximum operating power, 50MPH top speed, and 30 mile range. The bike was  stress tested with nearly 1000 miles of use, but then was stolen before I could take pictures of the finalized design :(
