Microcontroller Mod

[Breaktru]

Finally Completed and it works great.

I would have liked to put it in a smaller enclosure but I settled on this one. I searched for months and couldn't find anything I liked.

Next one will be smaller.

The next to last photo shows the button I would have liked to use but it was too massive.

I refrained from using a Digital Pot because I need a 200 ohm trimmer and the D.P.'s lowest value is 10k ohms. Having done this with my side x side mod, I know that adjusting voltage would be pretty crappy as the increment jumps are pretty large.

Features:

AVR ATMega328 - microprocessor

Amperage Sensor

Programmed w/ Arduino Sketch Software

FTDI output pins for future re-programming

OKR-T/6

USB Charging Circuit

Series 2x Li-Po 20c batteries for vaping

Parallel batteries for charging via USB

8x2 LCD Display

Slotted Vent Holes on bottom plate

Display Shows:

Output Voltage - Amperage - Resistance of Atty - Wattage - Battery Level in Percentage

I compared voltage and amperage with my Digital Multimeter and the Mod Display readings are exact.

Sweet! Love the switch - I have some that look just like that. Really nice.

Here it is with a DNA by Evolv in it:

With the right camera distance the display looks pretty clear:

Not so clear but over 11 watts. Max was 11.58 watts.
