dx 100mw labby question

[glona]

ok i got my dx labby it needs 5.0volts to power on and i have a wall adapter that goes at 5 volts could i solder this up and make it so i can plug into the wall?

as long as it can supply at least 300ma i think you should be fine

 

[glona]

how could i find that out?

 

[glona]

the think seas 5.0v---1.0A is that how i know?

That should be plenty. 1A=1000ma

Usually the adapter will list the polarity of the output wires. If it doesn't you can always try hooking it up both ways and see which one works.

wont it kill the laser if i hook it up wrong?

 

[MarioMaster]

don't you have a multimeter? or a fan or something you know the polarity of?

 

[glona]

nope i am goign ot get a multimeter this weekend

Don't you have a multimeter to check polarity? :-/

That depends on whether or not the laser has reverse polarity protection. If you don't want to risk it just hook the adapter up to a multimeter/LED/something else with polarity.

but if i hookit up backwords will it kill the diode?

If you are referring to the dx 100mw red module it has a decent driver that probably has some form of reverse polarity protection.

i dont know if i should take that risk
