i got my lava drive tday.. n i hooked it up to my 2AA pack, i was goin to test the mA on it... then it started gettin warm... then almost hot... i tried it with a 3.0V cr1234 n the same thing happened but i didnt let it get as warm as before

what did i do wrong... or what do i need to fix that?

thnx

The lavadrive [highlight]MUST [/highlight]have a load attached to it (a diode, a test load, etc.)  Otherwise it keeps trying to boost the voltage to make the connection [highlight]through the air![/highlight]!!  It is running so much voltage through it that it is heating up and will eventually overheat and die.  USE A LOAD

Peace,
dave

OOOO... i feel retarded now... lol... thnx ill hook up sum stuff now.. i always thought the test load was sum lil electronic thing that u had to buy n hook up to it... think ill use a dead diode

a test load is something you hook up to it. its a simple circuit board that helps you test the out put of the circuit board while you adjust it

Most boost drivers will die completely and instantly without a load, and I'm pretty sure this was the case with the v1 lava drives.

I think the open circuit protection of the new lavadrives are a zener with a higher voltage than our diode lasers. So I wonder why it would get hot?
