WTB dead/weak laser pointer pens






I have a cheap "50mW" green pen you can have if you want!

Just send me a PM and we can discuss it :)

You can buy a crapload of 650nm pens from ebay for less than $2 each. Cheaper than shipping a dead one...

I like the idea of making these pens with different wavelengths - might be a nice niche market. I'd probably buy 5mW 685nm, 520/515nm, 780nm, 808nm and 850nm. The only thing stopping me from building some is the difficulty of pressing/fitting it all :P
