If I ever build a laser, I will beyond a doubt start here. The price and WL meets my criteria. And where do you get the batteries?

Not necessarily. I think this is the first build to use this host. Here is a better description of how it comes
apart.
Fasttech sub $2 AA cheapie teardown review | BudgetLightForum.com
Basically, it all pushes out through the back. Enough force on the lens should do the trick.

lukily I bought 2, I think i messed the driver board with sloppy soldering/handling and had trouble disabling the second chip my nippers are not fine enough to cut those legs.
anyway i had to beat the heatsink and now i'm gonna have hell getting it back out, hopefully I can save the diode or haven't ruined it yet.
how can I check the diode by itself?

Only if you have a current mode variable power supply and know how to use it. Start off at 0mA and raise
the current slowly and carefully to 150mA. You might want to practice on a few silicon diodes before
trying it with the laser diode to make sure your power supply is up to the task.

oh oh, before you answered i hooked up the laser diode direct to the battery to see if it would light, it does, don't know how bright normal is but i would say this was very dim, did i screw them up?
I'm gonna have to order new drivers as it is, I pulled up a trace on the second one , don't know if that is why but my second build doesn't work either.

It depends on what the battery is and how much charge was in it, but yeah you probably did.

Yeah, it's called COD. Light comes out, but it's very dim LED type output.

for the second chip, you can just heat it up and pop it off, pull it off with pliers, pop it off with a screwdriver- doesn't matter.
LOL, Yeah I wasn't confident when doing what little soldering needed to be done and and handled and resolderd too much, fiddled and move the attached wires too much and it broke off, had to resolder that, a trace lifted on one when i ripped the chip off, on the other driver, part of the board came when i ripped it off.
I soldered the spring on and the joint popped when I pushed on the spring because i didn't solder it to sit flush. A comedy of errors and ineptness.
Anyway i have reordered everything and i'll give it another go in a week or so.
