ok so i am going to be build a 20x dvd laser from the 20x diode from high tech dealz
i am going to be using the adjustable rockstar driver is it safe to run that diode at 420ma with a 9v battery as its power source?

thanks,
dan

a 9v battery

Click to expand...

It won't last long at full power....ma/hr rating is too low 5 AA's would be better.

so are you saying that running it at 420ma is bad or the 9v is bad?

Neither is "bad".. just, a 9v isn't the greatest... It won't last very long before you'll have to replace the battery. A couple 3.6v lithium ion batteries or say, 6 or so larger alkalines would give you a lot longer burn time.

neither of the two are bad. If you use a 9v, the run time or how long you you can use the laser untill you need to change batteries will be shorter than if you were to use 5aa's.
Edit: you beat me

oo alright so it is perfectly safe to run the open can 20x diode at that current?
