Having been an avid Scrabble players for years (in my geeky youth I memorized all the two-letter words), I know how tricky it can be to replenish one’s tile rack while keeping the game fair. Troubles such as taking too many or too little letters, accidentally letting your opponent see your tiles, or outright cheating can befall a serious Scrabble player.
Taj Singh has attempted to fix this by building a beautifully designed Scrabble tile dispenser. It’s based on a PIC 16F628 microcontroller and a stepper motor. You push the button, a tile slides down the chute, and you take it to make your next play. Let’s take a closer look at how Taj did it.
Taj has done a fine job on this project and has also gone the extra mile in providing extensive documentation. Check out these links if you want to learn more about his PIC code and components, design features, and the motor and PCB window.
