A few newbie questions.

Some input would be greatly appreciated. I am wondering if something like this(see link below)
Wismec Reuleaux RX200 Jaybo Designs Triple 18650 Mod

Would Be a good starting point for a powerful hand-held? Using the unit to drive the diodes directly? The VR is stout, with one limitation-.2 ohms is the resistance limit. Yet voltage/wattage are user-settable from 0-9v and 0-250 watts. Made to house a trio of 18650's. The 510 connector is pretty standard, the duty cycle at .2 ohm output is continuous.... it exceeds the power requirements I do believe, yet that is adjustable. Several of the heads have set-screw power connectorsthat would direct-wire a diode pair......any input?

I haven't looked at the waveform this type of device produces. Given that it is driving a resistive load, however, I see no reason for it to have constant current or ripple-free operation. Unless the circuitry is designed way beyond what is needed for the original application, these will instantly kill a laser diode.

So basically no less than a pretty big resistor(inefficient) combined with a few caps to smith ripple would be needed. Was just an idea...

That said-im completely ignorant on the topic of lasers and haven't had time to read much...any links on the forum which show component size/requirements to do something in the 400-500 mw range?

Like I said in your Welcome thread....

"You will find a lot of build tutorials and Laser
related info threads here but you will need to
hunt them down.

0Most regulated devices will not work. You will get errors like no atomizer detected and over ohms. This is with the diode + driver modules. Take a look at the cricket upgrade kit on eBay. Or look for a series box mod, pwn is fine.
EDIT I get what your trying to do. You must use a driver made for lasers. You could consider an unregulated box mod or pwm box mod as just a power supply and connection interface. Don't bother with anything that detects resistance.
Here is food for thought.
