Raspberry Pi Chessboard

[@CallousCoder]

Hi Dana, I found kinship here :D I love chess computers, I fixed a couple on my channel and dumped the rom of the chess challenger with a homemade rom reader. But I also never ever gotten any good in chess. Up to the point that I don't like to play the game. But my fascination for the game came because my dad is into chess and his brother was even an international arbiter and he had all the new chess computers and he would bring them and they fascinated me (anything with buttons does :D) My dad actually became the arbiter and secretary of the CSVN (Dutch Computer Chess foundation), so there were always some chess computers or chess clocks around to be fixed by my dad. And I guess the are a piece of nostalgia for me. I did start to play Hnetafafl (Viking chess) though and even made a whole set myself and I play my old man during xmas and I can beat him with that game, after 46 years he is still unbeaten in chess by me.

Awesome job Dana! Thank you for sharing

Very nice project

[@ronaldmcdonald575]

Great video! Did you consider using reed switches instead of Hall effect sensors and if so what where the tradeoffs you anticipated? Apart from that, the sensors are connected to a multiplexer, aren’t they?

[@RichDMonte]

Hi, would you share the cad files for the PCB design?

Cool one question how dose the board no which piece is which dose it just remember when a piece is moved

[@danapeters]

The board only knows whether a square is occupied by a piece, but it cannot identify the type of piece. When the board detects that the opening position squares are occupied, it assumes you have placed the appropriate pieces on those squares. It tracks the movement of a pieces when a square becomes unoccupied and another square becomes occupied. This means that captures must be done carefully, by removing the captured piece first before moving the capturing piece.

@danapeters thats what i thought very cool project

Can the Teensy 2.0 Teensy Mini USB Development Board be used?

[@danapeters]

I don't think that the Teensy 2.0 would work, because it uses 5V GPIO, whereas the other Teensy models (including the LC) use 3.3V GPIO. The RPi uses 3.3V GPIO, so level shifters would be needed to connect to the Teensy 2.0. Much easier to get a Teensy LC, it is cheap and available.

where are links?

[@baekbaek-aja]

Can I use stm32f103 instead of teensy ?

[@danapeters]

Using something other than a Teensy would require significant hardware and software changes. Probably best to stick with the Teensy LC, which is inexpensive and readily available.

@@danapeters I interested to make this one, but I got difficulties by expresspcb service, do you have a gerber file for the pcb then i can use local pcb service to print it?

[@danapeters]

@@baekbaek-aja Sorry, I don't have a Gerber file for you. I might manually convert the ExpressPCB project to EasyEDA, and change the design to add the Teensy. If I did this, then a Gerber file could be exported.

@@danapeters thanks Dan, actually I onely have kidcad, but let me try your method 🙏

[@baekbaek-aja]

Hi @danapeters, I read your article regarding this board, but i still cant figuring out which file you put additional python code for serial communication to make picochess work with your board, would u assist me more... 🙏

LOL. ...because I was already subscribed.
