Component Scrub

Before conducting detailed design (and therefore requirements to modify the case internals or cut components), I wanted to quickly take stock of potential component lists to get an idea of power and space requirements.

I have included a quick power estimate based off these parts too.

1. Power

Allows the device to connect to power and run via cable, charge and then run off battery when away from a power point.

2. Computation

3. Input

Receives user input and transmits to RP for use as input. In this case, a Teensy LC configured as a keyboard with button ribbons connected to breakout board.

4. Display

Accepts power and visual data and converts into output on display. Display is mounted on case.

  • 7″ 800×480 Touchscreen LCD Display with driver backpack (Adafruit)

2407-13

5. Audio

Converts audio signal from raspberry Pi into boosted signal appropriate for in build Wii U Gamepad speakers.

  • Audio amplifier (ASSUMING NOT REQUIRED FOR NOW)
  • Speaker Connector Breakout

6. Chassis

Original or copy Wii U Game pad chassis with buttons and speakers to mount components, and house the entire assembly.

  • Wii U Gamepad Chassis

Total estimated max power bill at this stage is 5925mW.

Back of a napkin calculation for a reasonably priced 2500mAh 3.7V LiPO battery (9250mWh) is 1.4 hours of play time!

I will have to revisit power after space; either reduce consumption, boost storage or both!
