Hello,
Apologies for the novice questions.
I have a small device attached to an Arduino board that can trigger my camera to fire when the laser trip is broken. I've tested this using a cheap laser pen (Keychain Laser Pointer | Maplin) to start out with but noticed that the battery life isn't very long when the laser is on continuously.
I'd like to have something that can last 5-7 hours. I understand you can't just buy a laser diode, hook it up to some batteries and away you go but trying to find out a way of creating a mobile, long-lasting device has proved difficult. Can anyone refer me to a decent resource for this kind of thing?
Thanks,
Chris
