Texas Steampunks & Neo-Victorians
Today's small test demonstrated that the IR frequencies I'm working with pass through common window glass quite freely.
Quite useful, since my DIY pass filter is rather flimsy and would require a supporting substrate.

I've been experimenting a bit with using infrared (IR) phototransistors and LEDs as a proximity detector circuit for a possible future project.Continue

I've been playing with the flash circuit from a single-use camera, and after reverse engineering the circuit I've begun making some changes.
The standard design uses a blocking oscillator running on a 1.5 volt AAA battery to produce 300 volts across a large capacitor. The capacitor is then discharged through the itty-bitty flash tube in about 1/1000 second.
After some modification (removing the big capacitor, flash tube, and trigger circuit) and adding a…Continue
