USB passthrough help

[SmOoV_1]

My USB passthrough just died...I think some eliquid dripped into it...is there a way to save this thing..my life will be over with out it.....

Dripping can really kill a passthrough. A few people have tried to revive the auto switch in the device with mixed results. You could try tapping it on a hard surface or doing light puffs and draws on the device to unstick the switch. If these things fail, you could try (not highly recommended) to dip the threaded end into some hot water (not more than 1/2") for a few seconds, shake and let dry thoroughly. The water might help loosen the switch.

If you are the least bit DIY-inclined, rip out the internals and convert it to a passthrough with a manual switch. That can be done in an hour or less.

is there instructions some where for the manual switch modification for usb pass throughs?

No tutorials on this forum that I am aware of. Essentially, you gut the passthrough, connect the wire from the center conductor of the threaded piece on the battery to a switch and extend that to the positive wire from the USB cable. The negative, usually black wire, goes from the threaded section of the battery connector directly to the black/negative wire of the USB cable. Here is a poor rendition of the schematic.

How do you get the threaded end off the main canister? its easy to remove the LED end. However I cannfigure out how to remove the threaded end. I think I can figure it out once i get it apart.

i read somewhere that someone heated a 901 battery with a lighter while rotating... and then SLOWLY pullet out the threaded end with a pair of pliers but if it is female then i dont know how this would work... but i would recommend searching the forums in the DIY section seen some great threads about dis assembly over there... gotta DIG BABY DIGGGGGG...

You're probably not going to be able to use the same housing, if the passthru is the same size as a battery theres no way you'll be able to fit a switch in there. Just use a pair of pliers to crush the tube about a 1/2" below the connector, then crush it again the other way, grab the base (NOT THE THREADS) of the connector and pull it out, then strip off the autoswitch and circuit board and you're good to go.
