Default Re: Quick and dirty laser pointer (GB diode)

Well it has been a little under two weeks and the diode is still going strong with regular batteries. I try to keep it on for less than 30 seconds and give it a rest between uses. We will see how long it lasts....

You all may already know this, but DX has cases that go over your AAA's to make them AA size. *Do ya'll think that it would be a safe bet to run the 16x dodes straight with AAA's and it last as long as.... lets say a pulsar would?

I was going to put a link, but don't have enough posts. *Just serach "Converter Case" at DX and you can find them.

Anytime you try running straight off of batteries it is a gamble - and you do realize, that the house always wins in the end, right ? So - gambling is a lose-lose situation ! IT is risky, but can be done - you will eventually kill your diode that way, though- it is 100% certain to happen.

Amazingly a year later this laser pointer is still running fine. I currently use Duracell Ultras and have never put a driver in this pointer. I've given it pretty good use but have always used it less than 30 seconds continuously at any one time.

It still burns electrical tape without a problem so I think the power has held up pretty well.

sounds to me like you got a lucky diode! and have been very lucky with voltage spikes!

Now since you said that, It'll die today. *;D

I built a pointer without a driver and it worked for a really long time (about 7 months) untill one day I sat something on it unknowingly and it ran untill the batteries died. *Let's just say *LD + no driver + no duty cycle = dead diode. *;D *

It should work well as long as you don't leave it on for too long at once, and use 1.2V batteries. *

Nice bump btw! * ;D
