Pipboy 3000: Arm Mounted Computer #WearableWednesday

NewImage

Via sweatmanscientific.com

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.

Parts –

3D printer source files from dragonator.

4D Systems 4.3 inch touch display (datasheet) (programmer).

8 gig micro SD card.

Adafruit PowerBoost 500 charger/booster (datasheet).

Lipo 2500mAh 3.7v battery.

USB breakout board.

10 Position rotary switch.

3 orange LED’s (Radio Shack).

1 red LED (Radio Shack).

1-10k resistor (Radio Shack).

2-220ohm resistors (Radio Shack).

The Build

It all started with the dragonator’s files. I simply downloaded and printed them. I used two different colors because I wanted to test each printer head, as it was a new printer. In hindsight, I would have kept it all black. Also, the friend I’m making it for will be doing the painting and touching up the finer details and minor imperfections with some type of putty.

Lithium Ion Polymer Battery – 3.7v 2500mAh: Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2500mAh for a total of about 10 Wh. If you need a smaller battery, we also have a 1200mAh model

The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly. Read more.
