Tin Can Vape Mod DIY!
Benefits:
-Longer battery life then vape pens.
-Save your 510 threads, not used to charge.
-Faster charging, 1A charging board.
-Charge anywhere with a phone charge cord.
-LCD Voltage readout, know your battery level.
-It's an Art Piece.
-You made it!
These are all things I built for myself and my own use. If you build anything from this website, do so at your own risk.
Lithium-ion batteries are dangerous and can explode if anything is done wrong.

Prototype 1 Features:
-USB Rechargeable
-LCD Voltage readings
-510 vape connector (Salvaged from a broken vape)
-18650 battery
-Variable Voltage (did not work in this prototype)

(DO NOT MAKE THIS VAPE!)
I started out by laying out all the parts inside the case and picked where things will fit.

I then drilled the holes for the switches, cut 2 square holes (LCD and USB), and test fit the parts again.

The circuit board on the left is the USB charger for the 18650 battery. The board on the right is a variable voltage board, but this did not work in this design because it needed more than 5V to operate.


I mounted the circuit boards on double stick tape to prevent shorting out.
After a bit of wire cutting, stripping, and soldering. It was time to test the unit.

This is my test battery. I use it only for my initial testing. I have a nice Panasonic 3400mAh IMR battery for safety when I vape day to day.


The LCD screen is held in place with a bit of hot glue.

A lot of hot glue was put in here to keep things in place if I dropped it.
Turns out this wasn't a good idea when I decided to rebuild it and remove a lot of weight.

Here is the completed vape. The vape worked great, but not the variable voltage. That board needed more then 5v to run. I did wire it up from the USB, but that did not work.

The completed vape. I added some stickers and added clear tape on top to laminate it. Lasted about 6 months before some edges wore off a bit.

A few notes about this vape design:

We recommend 2.0 - 2.5 Ohm coils for this. Battery output averages 4.1v to 3.6v.

Warning:
Do not use the unit while the battery is charging from USB.
If you have a second battery, you can swap them out and use a 18650 wall charger.
Battery compartment is for nipple/button top batteries.
We recommended use of IMR or protected batteries.


A MUCH SAFER DESIGN:
I should have used a 3034 Mosfet N-Channel 40V 195A TO-220 (PN: IRLB3034PBF).
A resistor across the 3034 - 15K ohms 1/4W.
And a resettable fuse for each battery positive terminal. (PN: PPTC77) Act Temp 15A Hold.

The 3034 will allow a weaker button to activate the vape without melting the button contacts (if using too many watts from the coil).
The resettable fuses will prevent any issues and will turn back on after everything is ok.

The black box things on top are the IRLB3034PBF.
The white little boxes under are the PPTC77 Resettable fuses.
