Portable Gameboy 3D printer Monitor

made the printer monitor portable, wanted it to look like something, so found my old gameboy and made a scale model that would fit the electronics.

For the Battery i used a 1000 mah lithium battery.

for charging the battery and supplying 5v to the wemos is used this. i desoldered the USB A though.
