Black Star - A UV illuminator. I was never satisfied with the one I built using a mini fluorescent tube. But with the easy availability of UV LEDs, a new design option arose. I have a usable 18 LED prototype until I can get a more durable version finished.
Flasher - An emergency LED flasher using a modified blocking oscillator design.
LED Flashlight- A conversion of a incandescent lamp flash light to LEDs.
Photometer - A project to measure and analyze sunlight; loosely, an absorptive spectrometer.
