Hi there! I believe naming “automatic chessboard” is not so appealing so I decided to name it: Phantom. Even less appealing is to keep Phantom just to myself, so I decided to launch a Kickstarter campaign.<figure><img src=https://projects.arduinocontent.cc/73ebd192-d4cd-4701-8720-09d2ed5725aa.jpg /><figcaption> </figcaption></figure>During the last months, I have been sharing the development process and improvements made to the board week by week and got to the conclusion to close the first version to decide the following steps to improve it (Check out the whole process it the <a href="https://hackaday.io/project/179268-automatic-chessboard">Hackaday project)</a>.The next step is to be sure all systems are working perfectly fine together before starting important changes. The hardware of the first prototype is conformed by the Scara mechanism, hall effect sensors array, mecha-magnet and 3 microcontrollers running all the features.I’ll share with you all the files up to this version so you can build your own Phantom Chess, in the files section you will find everything you need: the assembly and 3D model files for each system<figure><img src=https://projects.arduinocontent.cc/bafe52be-6594-4526-8c28-5502a45fe905.jpg /><figcaption> </figcaption></figure><figure><img src=https://projects.arduinocontent.cc/eeceb06f-31ef-4b65-8cd8-8701800d1751.jpg /><figcaption> </figcaption></figure>Tavo developed a three stage software that controls all the features:<ul ><li >The main program is embedded into an ESP32 microcontroller. This software controls the motors and runs the calibration system to spatially the mecha-magnet.</li></ul><ul ><li >The second program read each hall-effect sensor to detect the pieces positions. I’m leaving you the code that controls the mecha-magnet here. Through an encoder, it detects the up and down positions and uses this data to control the motors that elevate the magnet with PID control. All this software is embedded into an Arduino Nano</li></ul><ul ><li >The third program focuses on connectivity. Through an Arduino Nano 33 IoT we communicate with the Lichess server to send commands as: start game, select adversary, game info and piece movements.</li></ul><figure><img src=https://projects.arduinocontent.cc/20665425-f9ec-4313-abd4-484d3f31068e.gif /><figcaption> </figcaption></figure>Files, schematics and further instructions are in our Github repository. Take a look at them and let me know your comments for improvements or questions to start building your own e-board!<figure><img src=https://projects.arduinocontent.cc/abf57810-a512-42c4-a3cf-db7d835e95e5.gif /><figcaption> </figcaption></figure><figure><img src=https://projects.arduinocontent.cc/b0e2b0f7-344b-432a-8d1c-ec809680dba7.gif /><figcaption> </figcaption></figure>I’ll leave our discord server if you need further information from me and to chat about chess: <a href="https://bit.ly/3emyBWy">https://bit.ly/3emyBWy</a>And my YouTube channel in which I upload progress and test videos: <a href="https://bit.ly/3w32wcf">https://bit.ly/3w32wcf </a>Now I’m also on instagram! <a href="https://www.instagram.com/phantom_chess/">https://www.instagram.com/phantom_chess/</a>

Phantom - Making My Own Automatic Chessboard

Developing an automatic chessboard. Our main goal is to recover the experience and unmatched feeling of playing OTB.
