A retropie based gaming console
I moved component into a new version of the 3d case, printed last week.
I moved the USB charging circuit to top right (so you can play while charging) and added 2 more screws holding the bottom of the case and 1 on the top of the case.
It works but there is an issue with sound : left and right channel are kind of mixed, so it’s not really stereo.
The project is almost finished. The case is closed, everything is connected, except top left & right buttons.
It is functional and kids are loving it.
However, there’s still room for improvement : battery holder are too thin, and buttons are a little flacky (the way they are hold is not optimal).
Mainly, it’s the case which need some adjustment.
The audio circuit is here to adjust audio from Rasbperry Pi using a B503 potentiometer.
You can find the layout on that amazon comments from driftinge30.
I’m designing the box to be 3d printed.
Work is in progress on github : https://github.com/paulgreg/retropie-portable-gamegear/
and follow Adafruit’s procedure: https://learn.adafruit.com/adafruit-dpi-display-kippah-ttl-tft/installation
Here is the layout for the jack connector :
And here’s the layout from the potentiometer from a review on https://www.amazon.co.uk/16x2mm-Double-Taper-Duplex-Potentiometer/dp/B00O9Y6Z70 : The pin layout (wheel down and pins facing up) far left-ground, (call it pin 1) from the far left pin 1-ground. moving right is 2-right input, 3 left input, 4-left output, 5 right output. 5=far right side pin.
Download and install latest version of retropie on a 8 Gb (at least) micro sdcard.
