High WATTS/AMPS - Boost MCU Mod w/ Nokia Display

[breaktru]

This mod has a AtMega328p micro-controller with a Nokia cell phone display. It is powered by a 20C Lithium-Polymer battery. The boost circuit is the good ole PTN04050C.

Voltage Range: 3.78v to 6.38v

PARTS:
ATMega328p AVR
Nokia Graphic Display
PTN04050C
20C lithium polymer 3.7 battery
1 amp USB Charger
100 Amp Sensor
Parallel 5.1A PTC resetable fuses
5A On/Off Slide Switch
18 gauge wiring
Aluminum Enclosure (size of a pack of cigs)

Maximum Results so far:
22.78 Watts
3.38 Amps
6.3 Volts output

The PTN04050C is spec'd at 12 Watts, 2.4 Amps yet I was able to achieve the above results.
This mod is far superior to the DNA mod on output wattage and amperage.

Hi, stumbled across your box mod while looking for a wiring diagram for a VV box mod.

Looks good. Was it all made by your fair hands? Looks quite complicated. Would have a go if I knew anything about electronics. How long does the battery last?

Good work

Thanks Jim, yes I made it.
I charge the battery the same time each day.

Sounds good, guess you have other devices for when this one is charging

With the Arduino board do you flash it through USB? Or do you need special connectors? would love to have a crack at something like this, maybe not with a Nokia display. Like the OLED screen you had in one of your other mods. Found the board on main board on Ebay for about £13, is that a fair price? Just one more thing, how much did it cost in total to build your mod, as the wife holds the purse strings

The chip can be bought w/ the bootloader so no flashing is necessary. Uploading sketches are with the FTDI module via USB.
Which board are you referring to? In this mod I used an ATMega 328p chip which is about $5 US
