A heart-filled story of trials and tribulations with blue LEDs.
lovely girl from the next town over. Things went very well from the start, with one exception - she, being afraid of the dark, cannot sleep without the TV on, and I, being easily entertained and distracted, cannot sleep with the TV on. After a bit of disagreement, she proposed that I ought to purchase a night-light, and that might solve the problem. I asked her what kind of a night-light she had in mind, and she mentioned that it would be extremely cool to have a blue one.
on sale at Sparkfun, my brain starting spinning. I could purchase a
boring, mass-produced night-light at the neighborhood grocery store
for two dollars, or I could spend quite a bit more and order some fun
new goodies from Sparkfun and design an LED-powered night-light from
Needless to say, I chose the latter. I purchased a fresh, new bread-board, some components, a bag full of those great LEDs, a few different proto-boards, new spools of wire and a few other odds and ends. Several days later, I spread it all out on my workbench and ended up creating what has got to be the most expensive, but certainly one of the most awesome, night-lights ever.
circuits 101 kind of stuff, but it works spectacularly, looks great,
does an amazing job of lighting up a room, and has ended all
disagreements about the TV.
…Plus, now my girlfriend thinks I’m some kind of genius. I showed her the schematic and insisted that it’s the most basic of all kid stuff electronics, but she still thinks it’s amazing.
