White wire?

[Blackwolf]

What do you do with the white wire on the dtr m140s.

You tagged "case pin" and don't know what to do with it?

Its there to set the host case connection. You know, case negative, case positive, etc...

I really don't know how "flashlights" or case pins work. I was hoping for something a little more in depth. I really don't want to fry another one.

Aight.
Everything depends on driver type...
Ie for a flexdrive:
Instead of passing a wire from the 'button-end' of the host, up to the driver, you just connect the battery "-" into the whole host. Its the button that makes this connection.
That makes a negative host build.
So you solder the white wire into the diode black wire (-) and to the driver "-".

What driver you have?

In all the pictures I've seen on LPF of similar builds there is usually just a picture of the red and black wires connected to their respective areas on the driver and usually covered in heat shrink.

If you're not building the laser into a host (flashlight, etc), then you can ignore the white wire.


edit: for better understanding, look the second page of the Flexdrive V5 user manual. Wiring diagrams. The flexdrive is a positive dc-dc converter, so you need positive to pass thru the driver. In the 4th situation you can read below it: "Connect diode - to case pin", which means "Connect diode black wire to white wire."

Gotcha?

The survival laser 1.25A Survival Laser Driver

Try ignoring the white wire with this driver.

thanks for all your help!

NP. You should only need this wire on specific configurations ok. Good luck and post pics for us :wave:

I'll be sure to. first I just need to save up another $53
