Pong console design based on AY-3-8500 chip. Custom circuit with composite video output. Circuit allows for multiple game selection options and single or multiplayer mode. Designed for 9V battery, but advisable to add linear voltage regulator circuit to use mains.
Paddle controllers and console casing designed in Freecad.
Controller bottoms have one version, there are currently two versions of the controller top half.
controller_top-v2.stl -> raised ring is 10mm high, text box is empty
controller-top_lower-debossed-text.stl -> raised ring is 10mm high, text box has debossed PONG text.
Use printed labels for labelling switch functions.
Schematics and bom available.
High infill for screw posts and other load bearing structures, supports necessary, raft optional to prevent warping.
Walls are 2mm, best to take this into account when setting your wall width.
Controllers are designed to be screwed together, but, depending on tolerances of your printer, I found they click together without any screws. If you use screws, don't over-tighten them to prevent snapping the posts. Use drill bit to enlarge screw holes if necessary.
9V-battery fits in receptacle, secure with rubber band or similar.
Secure cables for controllers in cable stress relieve, use a screw and washer and again: don't over-tighten screws. Alternatively, remove screw post inside stress relieve and tie a knot in the cable: slide the knot in the remaining portion of stress relieve.
