Arcade Cabinet for Tablets: Difference between revisions

Latest revision as of 13:40, 14 February 2014

The goal of this project is to provide arcade-style cabinet for 11-inch tablets.

Hardware

10 mm plywood or MDF
1 Joystick
8 (or less) Arcade buttons
1 power switch
1 Arduino Leonardo (better since it can emulate a keyboard or a mouse (HID))
1 Bluetooth module for Arduino
2 4-ohms speakers (recycled or not).
1 Audio amplifier or 5v Audio Amplifier
1 Android tablet

Extra

Humidity and Temperature Sensor - RHT03

Design

Figures for laser cutters (PDF and ODG formats) Media:ArcadeCabinetTablet.zip
Electronic Schema (Fritzing)

Software

Arduino sketch
