18650 5x Charger

update: 07/05/2017 - I just ordered a 5v power supply, this design works, but it gets hot. If your interested in V2 then check back soon for a charger that requires a 5v power supply.

This is a 5x 18650 charger that uses TP4056 Charging modules and L7805 voltage regulators. the two wires in the side are for a 6-12V source and the voltage regulator modules should be bent as shown in the pictures for the 12V, 0V (ground) and the 5V output (from left to right) if you are not sure, just google image search the voltage regulators to find a diagram. the 5V lead is bent 90 degrees up and goes straight into the charger module. there is a bit of wiring and soldering to be done to assemble this charger. but if your charging as many cells as I am, it is pretty useful to have. I didnt glue any of the electronics in, I figured they could use all the cooling they could get, I did glue the 'spring and bump' battery contacts in. currently I am powering this charger directly from my 3d printer power source, and using the part cooler on the extruder to cool the electronics. I think a fan is sorta necessary. maybe it is hot because I am using a 12v source rather than a 8-9v source. those regulators are burning off a lot of heat. good luck and happy printing.
