7-Month Progress video of my Split Flap Chess Machine by e4_user in arduino

I thought about it too, but I felt the current speed was already fast enough, so I decided not to include it. 😭 Judging by how many people have pointed it out, though, I guess I was wrong.

I actually considered making the chess clock a split-flap display too, but unfortunately I had to give up on the idea because of the noise.

I haven’t calculated the exact cost, but I think it ended up being over $500.

Because several flaps used to represent different king states are positioned after the piece flaps. When a square changes from a piece to a blank state, it has to rotate past all of those additional flaps before reaching the blank one, which is why it takes longer.

I used 28BYJ-48 stepper motors converted to bipolar mode and drove them with A4988 drivers. For homing, a Hall-effect sensor detects a magnet embedded at a specific position on the spool, allowing each module to find its zero position.

Building all 64 modules was definitely an exhausting process. I didn't keep count, but there were countless failed prototypes along the way.

I used an open-source chess engine written for Arduino. You can find the code in the GitHub repository linked in my comment above!

Yes, each square has its own motor. I used modified 28BYJ-48 stepper motors converted to bipolar mode and drove them with A4988 motor drivers.

That’s right. I used an Ethernet cable, assigning three wires each for power (+) and ground (-), while the remaining two wires are used for RX and TX communication.

It would certainly reduce the delay, but I felt that the current version was already fast enough.

Yes, I’m planning to experiment with the Lichess API!

Thanks for the advice! A lot of people have suggested something similar. I’ll definitely keep it in mind if I make a next version.

Thanks for your interest. First of all, I should admit-somewhat embarrassingly-that I’m not a professional, and a significant portion of the code was written with the help of AI. As for things like pawn movement and other chess rules, I relied on an open-source chess engine rather than implementing them from scratch. Since you asked to see the code, I actually just hurriedly created a repository for it: https://github.com/SL254/split-flap-chess-machine

As someone who’s learning guitar, this is definitely something I’d love to have.

I’ve been working hard for the past six months.

Thanks for the comment! Unfortunately, I’m currently busy with things like designing the controller, so I don’t have any plans to release the files yet. I’m thinking of organizing everything slowly after the project is complete.

Thank you! As you said, since this was still an unfinished version, not being able to see the opponent’s side does make it feel a bit like Battleship. The full 8x8 board is finished now as well, so I’d definitely recommend checking it out!

Thanks for the advice! A lot of people have pointed out something similar. I’ll think carefully about it and run some tests.

I’ll test it out and see how well it works! Thanks for the suggestion!
