One of my favorite features in Design News has a new “Gadget Freak”, fun read –
Why putt golf balls into a paper cup when you can have your own variable-terrain putting green? This course designed by Mark Giannasi, Aaron Gaylord, Brody Collins, Thomas Boileau and Maiki Vlahinos offers players three cups and three skill levels. The most advanced level raises two platforms that change the terrain of the course – and the challenge that golfers face. But even with only three “cups,” you can still shout “Fore!”
Schematic and PIC code included.
