The video is in español, so you may or may not be able to fully follow along 😉 (You can optionally enable Closed-Captions and select english in the translator under the settings cog wheel icon – I didn’t now about it either!) Still, very entertaining to watch Oscar build it!
The main components Oscar used are a Raspberry Pi Zero, a whopping 7″ LCD IPS (1280×800), an Adafruit Powerboost 500C, a 2000mAh lipo battery, DC 4-25V converter, an Adafruit stereo amplifier (TPA2016), two tiny speakers and a perfboard for the gamepad. Oscar hacked apart an SNES controller and repurposed the button caps and used 6mm tactile switches (the awful “clicky” ones 🙂
To get I2S audio from the Pi Zero, he put together SMD resistors, some capacitors and followed the Adafruit learning guide for wiring diagram and reference.
The IPS display seems to be composite, but looks pretty good!
The build looks very thin, compared so some of the other builds I’ve seen. Very good wire management helps keep that possible 🙂
