Just finished my Pipboy 3000 build. Adafruit’s PowerBoost 500 board worked perfect for this project. Thanks!
From his project page:
I’m not much of a gamer. In fact, I have never played any of the Fallout games. But when a friend asked if I could build this “Arm Mounted Computer”, I was intrigued. A quick Google search revealed that this was indeed a very popular device, and several people had already built them. This is the story of my attempt….
…The Adafruit power circuit serves four purposes:
- To convert the 3.7 volts from the battery to 5v for the display.
- To provide a charging circuit for the battery.
- To provide a way to power the device on/off without the need for a high current switch.
- To give the operator a warning when the battery is low.
That little board of theirs does all of these things.
- The display pulls about 250mA at 5v, so the battery will last ~10hours on a single charge.
- All I have to do is pull the EN pin low, and this will shut the booster off. Meaning any type of switch can be used to power the
- Pipboy On and Off (I wound up using a switch FAR larger than I needed. This will change in the Mark 2).
- There is a LB pin that will go low when the battery drops below 3.3 volts. This triggers the display to throw a “low battery” warning screen.
