Original Gameboy Null with 3D printed case

Post by schlagt » Thu Jun 20, 2019 12:57 pm

Hello everyone,

I just wanted to share/show off my first build. It's an original GB Null from Ampersand with a 3D printed case an custom PWM audio.

Unfortunately I forgot to take the final pre-case-closeup pictures, therefore the audio is not yet wired to the Pi on the respective picture.

I've been using stereo audio with a PAM8403, a 1000uF decoupling capacitor and some smartphone ringers/buzzers. The stereo filter is the one described by SP33 in his fabulous (PWM audio guide post [1]) implemented with a custom minimum-size layout including a ground strip.

I also decided to include one of the cheopo battery status indicators one can find on eBay/AliExpress [2].

The screen lens/cover was made from 2mm acrylic glad.

The case [3] was wet-sanded with 120 to 400 grid sandpaper, then primed with 2 coats of spray filler [4] and finished with 4 thin coats of nitrocellulose lacquer spray.

It was a really fun and easy build thanks to Ampersand and all the great resource on this forum.

Which photos? Do you mean the lens/screen cover?
