Crappy weather has lead me to small project I've been meaning to do for ages. Build my own flashing tank light to replace those cylume sticks.
The pictures are pretty self explanatory, and, as you may also notice, I didn't spend much time making it look pretty.
Parts list.
AAA battery x 2.
Flashing LED about $1.00
Reed switch $1.50
Housing is an old toothbrush container used for travelling.
I wanted a normally closed reed switch, but they must have given me the wrong one so I need to come up with a way of holding the magnet in place. I am also yet to seal up the end, just plan on filling the end with silicone.
I have a MkII in mind where I have an old rear bike light that has a module incorporating a couple of flashing modes. Instead of using the button to switch through the modes I think I could use the reed switch and then would only need the magnet to turn it on a off so could leave the magnet in my car.
