[Tim Higgins] picked up an old pachinko game at a garage sale for his wife, but it ended up sitting unused in the garage for a few years. When he finally dusted it off, he decided that he wanted to restore and build a nice cabinet for it, though he thought the idea was a bit lame.
He says he likes to use some sort of CPU in his projects, and even though it was overkill, he made it his goal to add some sort of microprocessor to the game. He didn’t want to ruin the original aesthetics of the machine, so he decided that he could use an Arduino to drive a rewards system for skilled pachinko players.
Using some PVC pipe, he built a treat hopper which is controlled by the Arduino. When the player wins, the microcontroller triggers a small hobby servo, which dispenses gumballs/candy/etc.
[Tim] says that his wife loved the gift, and he was quite pleased with how it came out as well. Hit up his blog for additional build details and be sure to check out the photo slideshow of the restoration that we have embedded below.

Instructables user [knife141] enjoys restoring vintage electronics in his spare time, especially old radios. AM radios tend to pique his curiosity the most, and in this tutorial, he discusses the restoration of an old radio from the early 1940s.
While people would likely assume that the vacuum tubes in a radio this old are the source of poor performance, he has found that most units he repairs suffer from bad capacitors. He says that the old electrolytic, paper, and wax caps used in these radios were never meant to last more than a few decades, let alone 70 years.
He always starts the process off by discharging the caps and replacing the power cord, both as a safety measure. He was pretty sure the capacitors were bad in this radio, so he swapped all of them out, regardless of condition. All of the internal wiring was then checked over, and any damaged cables were replaced or covered with heat shrink tubing.
With that done, he powered on the radio and was happy to find that the distortion he previously experienced was completely eliminated. With the electronics taken care of, he tackled the radio’s asbestos insulation by encapsulating it with varnish. Attention was then turned to the exterior, where he cleaned and buffed the leather, refinished the face plate, and polished the dial’s cloudy glass.
While it’s not exactly a hack, we always like seeing vintage electronics given new life, and we’re always cool with saving these sorts of things from rotting in a landfill.
[Richard Cabrera’s] iPhone was scratched from years of use. A big part of the appeal of Apple products is the dose of sexy that comes with them, so he set out to remedy this abomination. His iPhone case rehabilitation guide walks you through the miraculous transformation. One of the tools he uses is a headlight lens restoration kit from 3M because its polishing pads include graduated levels of grit for the transition from rough sanding to buffing. As you can see, the logo and text have been buffed off but that’s a small price to pay for what looks like a shiny new device.
Many of our cherished computers and consoles from the past have not stood up well over time. It’s not the hardware as much as the color. From Commodores, Apples, to Super Nintendos, the machines have slowly drifted towards a sickly yellow and even brown. The culprit appears to be the fire retardant chemicals used in the plastics. Amiga enthusiasts have spent the last year perfecting a technique that restores the plastic of these machines to its original splendor. Dubbed ‘Retr0brite‘ it’s a gel made from hydrogen peroxide, xanthan gum, glycerine, and ‘Oxy’ style laundry booster. The results are really impressive. If you do start restoring your own machines, caution should be used since it requires strong concentrations of hydrogen peroxide typically employed in bleaching hair.
