It's thinking....

Ok, I know I've been away for a few weeks, as luck would have it I got some time in the woodshop and put together the first "BrainBox" for my SishFishPi platform.

First, more on the SishFishPi for those just joining us. It's a basic chess computer built using the Raspberry Pi Linux development board, the amazing Stockfish engine, and commodity LCD/electronics. The SFP integrates with a new software build for the "Sish" chess board.

The end result, a small form factor butt kicking chess machine.


Now I'll put together a more detailed post on how it was built and finished, however just a few details to get you started:

The BrainBox itself is made of red oak finished with roughly a dozen coats of "black shellac" which I purchased from shellac.net. The sides each have a "brain" design cut into them with a scroll saw, behind that design I placed cut pieces of translucent plastic to difuse the light. After that I built a small "light board" inside the case that uses the Pi's GPIO PWM pin to slowly pulse light over a sine wave like design. Here's a picture of the inside..


Lastly an LCD has been added (simple Sparkfun or Adafruit HD44780) which outputs the brainbox's moves.

Here's a video to give you an impression of just how cool this ended up.

The end result turned out very cool, and now that the SFP/BrainBox has got a home I'm sure I'll have more time to finish up the code and get something posted up here.

In the meantime enjoy the video!
