Right after an upcoming trip, I will begin building a Skee-ball machine. I know this has been done before, and will be again, but I am throwing my hat in the ring as well. I was born and raised a block from the beach and boardwalk in Atlantic City, so arcades and a keen appreciation for Skee-ball in particular is pretty deeply ingrained. I will use a Raspberry Pi to control everything, and already have library routines writing to a smaller four digit, seven segment display. I have three 4" high seven segment LEDs for the score, and a single 2.5" for "Balls Played". I found and purchased an original Skee-ball marquee on eBay, along with nine real Skee-ball balls, and have just finished making the ball target chutes from a variety of sizes of PVC pipe. I also bought 4" x 1/4" UHMW poly strips for the big hoops, and a roll of 24" wide x 1/4" thick cork roll for the playing surface, and seven IR object detectors to record the balls as they go through the chutes. I even found a place that sell bright yellow 1/8" thick plastic for the trim. The primary structural element will be a 28" x 81" hollow core door. and everything will knock down to allow it to be brought to events. I will begin the large wood pieces in the first week of February. My one question is the angle of the target plate; from drawings that I have seen, this appears to be 38 degrees, but if anyone could confirm or correct this, that would be greatly appreciated.
All the best,
Kevin
