As the second video, I decided to make it more complicated than the last one. This board is a 2×2 button matrix ‘processor-board’.  What I mean by that is that this board is still dependent on the 2×2 button matrix board, from Sparkfun, but the processor and basically the whole product is from this add-on board.
As for the music, I wanted to make it more peaceful. I’m so glad I found this song online.  All my songs are pulled from the artists at Newgrounds audio portal.

This video was sped up to 32x the original speed which was 2:27:48, wow!
This board is being quoted for fabrication right now although if I were to sell it now, the price would be around $65, and that is using the prices for 1 piece at a time instead of bulk purchases. I will be doing a kickstarter for this soon, once my quote comes in. If that is successful, I should be able to bring the price down to about $30. Oh and there is an IC missing in the video because I don’t have the footprint for it already.
