A new DIY handheld games console has been constructed by Thingiverse member miniarcademachines which has been inspired by the Sega Game Gear and builds on the previously available 2.8 inch version.
The latest design incorporates a 5 inch display and is powered by a Raspberry Pi 3 combined with an audio amplifier, 2500mAh battery and 16GB of storage.
– Raspberry Pi 3 – Model B
– Adafruit Mono 2.5W Class D Audio Amplifier – PAM8302
– Breadboard-friendly SPDT Slide Switch (check measurements before ordering, i use non standard switches)
– Lithium Ion Polymer Battery – 3.7v 2500mAh (cylinder type, look like AA)
– Mini Metal Speaker w/ Wires – 8 ohm 0.5W
– PowerBoost 1000 Charger (500 will work with using a smaller screw)
– 16GB sandisk or samsung class 10 SD/MicroSD Memory Card with retropie/attract front end (link can be provided for a download because its real tricky getting the lcd to work)
– 5 in TFT lcd for raspberry pi (waveshare brand with holes is what i use, but you may find other cheap ebay ones that might work)
– 6mm Tactile Button switches
– 12mm Tactile Button switches

This version is an expansion on the 2.8 inch version. The internal components besides the screen are the same. The added features on this one are that you have an external usb to connect a keyboard, or joystick to, and there is enough space to use 2 cylinder batteries to maximize play time. This design was inspired by the Sega Game Gear, and closely matches its size in both overall dimensions, and screen size.
The idea was to make a better version of the pigrrl 2 that was so uncomfortable to hold. The improvements are that it has increased battery capacity, available hdmi, and eliminated the awful speaker hum that the pigrrl 2 had. This design incorporates a teensy for the controls so you have true analog for the joystick instead of just a dpad function like other projects. basically i took all the features i liked from other projects, took out the ones i didnt, and added what i thought should be there. I look forward to more designs in the future, and i hope that this one being released freely increases the interest in it.
