I bought 5 of those balls, the more you buy the better the discount so it wasn't so bad. Hopefully they match good, if not i'm sure my kids can piss me off by throwing them all over the yard.
Also, the khars switch kit starting giving me a little trouble. The ball count was adding 10 points once in a while. It has lights on the little board that tells whether activating 10 points or ball count and only ball count was lighting. So I emailed Rob and he quickly gave me a really technical response with a handful of ways to solve the problem.
In short, the micro usb cable needs to be Charging Only, not data. I couldn't find one that was only data at my house, so the quickest easiest solution was to slit the usb wire open and cut the white. Which appears to work.
I was impatient (the website says 2 day delay for kit) so i figured i would just use my own because i wanted the display kit by last Friday. But maybe if you are going to purchase, buy the kit, it's not so simple on amazon to figure out which cable doesn't do data.
Before i did the switches, i sanded and painted the bar that holds them, i used Gloss gray from walmart (my wife has walmart plus). Came out pretty good. I was tempted to armoral the rubber, it's cleaner in person than in pics, but i figured the balls would pick it up and make a mess.
Next up is adding permanent power, wiring for a switch up front on the machine and organizing the rest of the wiring. Since i'm an electrical contractor, should be fairly easy, i will likely use Gray UF wire, since it's quite a bit tougher to damage.
