这是我的便携式树莓派游戏控制器。它厚度为3.6厘米，宽度9.6厘米，长度13.6厘米。在内部运行的是树莓派2，搭载Retropie OS，可以模拟从1977年到2003年的几乎所有游戏系统。此外，还安装了Raspbian和Kodi操作系统。

屏幕nThe screen is a cheap composite backup camera screen from amazon. It has a resolution of 480x320 which might not sound as much, but it's no problem at all when playing retro games. Because the screen is made to work in your car it does need 12V to run out of the box. This however can be fixed easily, so that it runs of 5V :)

BATTERYnBattery wise it has a 6000mAh rechargeable Lithium ion battery which gives it around 4-5 hours of play time.
nTo charge the battery it has an Adafruit PowerBoost 1000C which can charge the battery in about 5-6 hours.

SOUNDnThe two built in speakers come from an old broken Nintendo DS Lite I had lying around (those could be replaced by the mini metal speaker from Adafruit). The audio signal coming from the Raspberry Pi is too weak to power the speakers on it's own, so it needs to be amplified. The amplifier is from an old cheap pair of external speakers for an mp3 player that I had lying around too (It could be replaced with a pam8302 amplifier from Adafruit). To turn the volume up and down it has an analog "slider" from an old pair of headphones (You could probably find something similar pretty easily).

BUILT IN CONTROLLERnThe built in controller was the hardest part of this project, or more specifically the ANALOG thumb stick. The built in controller I made myself, it's a breadboard PCB with tactile switches, and an analog thumb stick on it. The tact-switches were pretty easy to connect, but I had a lot of trouble with the thumb stick!

ANALOG THUMB STICKnBecause it's analog the Raspberry Pi cannot understand it right away. The signal from the thumb stick must be converted to a digital format first. If I had been a master programmer I could probably have gotten away with buying an ADC (analog to digital converter) and then writing a driver for it myself. But that did not work for me.
