Hello Picochess friends
After a break of several months I have finished my Raspberry-Elfacun-Mephisto-Picochess project (PEMP).
As you can see from the pictures, the left slot of the Exclusiv board contains the Raspberry 4B with sound card and loudspeaker. The middle slot is empty. On the right is the Elfacun module.
The Raspberry is powered by the original Raspberry power pack. A USB-A plug is plugged into the Raspberry, which supplies the Elfacun module with energy. The two wires for this are soldered to the underside of the Elfacun module board. Thus, the drawer can also be closed during the game.
As is often the case, I would do some things differently today.
At first I thought it would be a good idea to be able to pull the Raspberry tray out the front of the drawer. The height within the slot is not sufficient for this. So I made a design change to the Raspberry. (See picture) I wouldn't do that anymore today.
This PEMP project is also not suitable as an experimental station where the SD card has to be changed frequently. This project is for play only.
If you do without the possibility of being able to pull out the Raspberry slot to the front, you have more installation height available. The board can be opened from below with the 4 screws and you can easily access the contents of the 3 slots.
Then maybe you can do something to cool the Pi4.
In my project, a game with 4 cores is probably out of the question because of the heat development. With my skill level, however, 1 core is completely sufficient.
Otherwise there are no restrictions. All the functions of Picochess V3 can be used and in addition with the LED display of the fields. (Online, Engine, Emus)
The video gives an impression of the build-up of the position, play and taking back moves.

Of course, the Pi can be reached via WLAN.

Hi Wilhelm,
Very nice …
I’m hoping to get a v2 version of the Elfacun soon which should support most, if not all, Mephisto cartridges. I’ll be testing it for Pablo …
