Evil Eye Tech Experiment

Evil Eye Tech Experiment

This wasn’t so much a useful project as it was an experiment with some technologies I’ve wanted to play with. Capacitive Touch sensing LED Multiplexing PCB Art   I thought I could combine them to make a stylized Turkish “Evil Eye.”  It would: Sense when you […]

3,900 Mile Radio Transmission

3,900 Mile Radio Transmission

This project was a prototype replacement for the transmitter on my long distance pico balloons (link).   The pico balloon flight computer uses APRS which: Takes 5 seconds for each location transmission Has a range of 150 miles   The duration is good.  Short messages […]

Photography from 100,000ft

Photography from 100,000ft

I set out to take photographs at an altitude where I could see the curvature of the Earth.   The premise: Float a balloon to an altitude where you can see Earth curvature Have a camera rig suspended below it, taking pictures continuously Computer system […]

Home-Built PCB and Embedded Controller
