home vaporizer idea.

[Subject:09141987]

This being the digital age everything plugs into another device via usb, as of course my passthru does. Don't get me wrong I love my passthru, however the cord is short, and ive noticed using it while its plugged in has started to loosen up the connections some, i have a few cheapo 510 e cigs lying around, and a large quantity of wire, power supplies, micro usb cables, and tubes. So naturally I feel some tweeking is in order. So here's the idea.

I would like to make a wall socket powered VV for use when at home. A manual of course, with an on/off switch, and LED. I come to you guys of course because I'm sure one of you geniuses have already done this. Please, hit me with some knowledge.

I've just made something similar, in that it's a mains-powered PV. The thread is on the next page over, LCM: The Low Cost Mod. Mine isn't VV, just a power resistor to tune the wattage at the atomizer, but a lot of people have chimed in on using an LM2596 with it.

The LCM strips the PV down to its bare minimalist essentials, but with the concept you could hang as many bells and whistles on it as you want.

One of the first things I made when I began vaping was to make my own passthrough since I was tired of batteries at home. You can make one quite easily for <$20 in parts with the only specialty piece being a 510 (or desired atty) connector which can be salvaged from a dead battery or ordered from madvapes etc.

What you need:
- A project box (mine is a small one ~2"x4")
- A battery connector for desired atty
- A sturdy switch that can handle repeated pushings and enough amperage (i used a non-latching metal footswitch which works splendidly, cost me $3 but its worth it after I broke a bunch of plastic ones)
- A 10W wirewound resistor 0.5-1 Ohm (tune to desired vaping voltage, acts as a current limiter to save your atty)
- A rocker switch (for on-off safety)
- A surplus 5V wall wort (that can deliver at least 2.5 amps) can be found probably around the house or at an electronics surplus shop.
- an LED
- a 1/4W >250Ohm resistor. (for 5V and assuming your average Led consumes ~20mA)

Then its all patience, drilling, wiring and gluing. I would definitely heatshrink the connections for safety, its easy to do. I made my selectable voltage by using two 10W wirewound resistors (at 0.5Ohm for high and 1.0Ohm for low which delivers 4.25/3.75V respectively) and using a 3 position rocker switch for my power switch (low-off-high). I also used two LEDs, one for power on and the other for vaping (which happens to be a flasher just cuz I could).

To make it truly VV you would need a voltage regulator and potentiometer (i plan to do this someday when I have time, madvapes sells an adjustable regulator and voltage display)

If you need the schematic or pics, let me know and I can do it up.

OK because i have no life here's my passthrough. As you can see, simple to make
