you can bybass the IC and make it 16v 
EDIT: wait there is no IC lol i meant t3h mosfet

How do i do that ?L@z3r said:[quote author=HumanSymphony link=1234032611/0#3 date=1234033509]you can bybass the IC and make it 16v
EDIT: 200th post w00t !![/quote]
Simply a jumper wire from the positive input to the mosfet pin. I had ryan do it for me a couple times. He's the one who told me about it

[/quote]Hey Nick, Do you have a picture of the Mosfet or w/e its called ? Or can you show me a diagram ? Thanks

It just struck me that this could be pretty helpful in builds that use a three AAA carriage. It is VERY difficult (although granted not impossible) to put the batteries in backward when using a battery carriage.
The only other real issue is that the excess voltage is being converted to heat.
Peace,
dave
[highlight]**EDIT**[/highlight] Something else just came to mind. If someone blows the driver by giving it too much voltage, can the driver be salvaged by placing this jumper to bypass the mosfet?
Connect what points ? the arrow only points to 1 leg of the mofset ???HumanSymphony said:Connect the points as t3h pic shows.

[/quote]Oh the pos input. Ah i c. Thanks. So i just solder a wire to the 2 points ? or can i jut put a blob of solder on it ?

should probably just use a wire.

are you 100% sure this method will work ? I don't wanna kill my driver or my diode. Will the diode still be safe ?
Also why when i use a 9v battery it works good, but then when the battery dies down to around 8volts the laser will no longer light a match ? so will 12v make it more powerful ?

When the 9V battery dies down, the laser won't light a match because there is now insufficient voltage to supply the diode and the regulator's overhead voltage. The regulator drops out of regulation. By going to 12V, you will not make the laser more powerful, the diode will still only get 130mA from the driver. You will not have the problem of the laser going weak on you as soon as the 9V battery starts to sag. With 12V of batteries (maybe 3 x 10440 or 3 x 14500 in a radio shack battery holder, the laser will hold its power level until the batteries are exhausted and need recharging.
