Artwork on the wall is nice and all, but don’t you get bored with it sometimes? What if you could interact with it! That’s just what the [Artless Dodger] decided to do with this old Fidelity Chess Challenger he converted to a wall-playable chess set!
The old Fidelity Chess Challenger is a fun electronic chess set that works by operating on press input. Simply move your piece, press down on its new square and then the computer knows where the piece is. The system is just begging to be hacked into a new form factor.
He’s built the new board from scratch using MDF, and then coated it with faux leather vinyl to give it a more polished look. He’s upgraded all the switches to momentary button switches and then re-soldered all of the connections. This was a bit of a challenge seeing as the original buttons looked like this:
After that headache was done, he also added LED notification lights to help the user see the moves and whose turn it is. A cool feature lets you double-check the computer knows where all the pieces are. Simply hold down the buttons along the bottom to reveal the supposed location of the corresponding chess piece.
He’s got a great write-up on his blog if you’re interested in seeing the rest of the build — if not, at least check out his demonstration video!
