Step 6 Building the Circuit

NOTE: This requires an experienced solderer and a real good soldering iron with small tip

Wire the driver according to the following picture. The second picture is the flip side of the driver.
Be sure to add the resistor and the switch as show in the the final wiring pic.

Using a multimeter set to check milliamps, put the leads between the end of the resistor and the diode. Power it with no more than 3 volts and adjust the pot on the driver to no more than 170 mA. I used 2 button cells, taped together on the sides, harvested from an Energizer 12V 123 battery I also used two small magnets to attach the (+) positive and (-) negative leads from driver.

how can I make this driver circuit

awesome

I'm not quite sure i get how the resistor is put into this circuit, in the picture it appears to be shorting the two terminals that go to the diode,and i'm sure that isn't it.  If somebody could please clarify, i would appreciate it.  i dont want to screw up the circuit and risk ruining the diode.

Thanks!

The 12v Batter is actually A23, if I'm not mistaken, not 123. It was hard enough when I knew I was looking for an Energizer A23, so I thought it would help to add that.
Anyway, I already have removed the on-board momentary switch, so I don't know how viable it would be to use needle-nose pliers, but I do know that if you use tweezers, and grip the very bottom of it, then rock it slowly, gently, and especially carefully, left and right, you might be able to snap it off without damaging anything (except said switch that you would probably discard). That's how I removed it, and I don't think anything is damaged. --Yet.

Good luck!

looking for a wire diagram for the set up here cant my laser to work also will the laser work with a 12v battery?

[jacko16_730]

dude have you made it work with 12 volts????????????????????????

[your dog]

you can't do that (while you can, but) it will kill the diode

here is a way to make your own circuit. (it's very noobish though)

im tryin to juice this thing up......................... it would be a big help if somone already knew what to do................................... what exactly will i have to replace.......................... what can i keep.............??????????? how can i stop the diode from burning out?????? any ideas.........???????????

How do you remove the momentary switch?

Where does one get these parts for this step? I'd definitely like to learn how to do this. Schematics would also be cool to have.
