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.
