PCB a Week 14: Hello-ot

in project logs by DP | 4 comments


Mats continues his challenge of designing one PCB every week.  In week 14 he came up with Hello-ot:

Being able to change between, black (off), red, green and yellow (quickly alternating red/green) my plan was to make an Reversi/Othello game with them and have it all fit on a 10×10 cm pcb.
For selecting which tile to add I added one horizontal and one vertical row of tactile buttons so the player could press the buttons corresponding to the row and column that he wanted to play.

    Why not just use two pots to control X & Y locations?

    Wow Mats your a machine! Impressed with your speed.

  3. Two pots is a nice idea, might use it in a future version of this…

    This design was flawed, so although I’m speedy I don’t have a 100% track record for good designs :-) The board can’t handle bi-color leds as I had planned, but a new revision of the pcb is ordered.

    It is still a nice design though!
