We’ve got snake (Python) brains! All the solenoids in the prototype playfield can now be controlled by the raspberry pi, and my python library! 😀 That’s really exciting because it means that the entire electronics flow from software to physical motion is past the drawing board. Basically, we now have proof of concept for the […]
Read MoreMore Pinball Circuit Theory
There are several elements to the pinball circuit. First, it should be noted that this circuit doesn’t bother with lights. All it’s concerned with are the main assemblies, and their controls. So, on the top left side of the figure is the logic level converter. It’s not really an IC, just a small board with […]
Read MorePainting the Pinball Cabinet
Let’s get some paint on that cabinet! I used Rust-Scat, a high-gloss, polyurethane enamel paint. There it is with the first coat on. (Lighting is off because it got dark) The second coat is yet to come. There it is dried. The paint definitely needs a second coat, to help with the splotches, and the grains. The feel of […]

There’s been a lot of electronics work that’s gone into this project. And it’s not over yet by any means. But here’s some interesting pictures explaining how I went about some of it. That’s the 50vDC Power Supply. For the flippers and a few other soleniods. It’s really simple. Transformer, Bridge Rectifier, Enormous Capacitor. Here is the […]

Cabinet Construction
Ack!! Run!!! It’s a Pinball Skeleton!! I now have a skinless, gutless, legless pinball machine. This is where my build really starts taking shape. I have yet to mount the backbox on the cabinet, but that’s on it’s way. It’s supposed to either pivot down and fold up, or be dis-connectable and it’ll pop up, […]
Read MorePinball Graphics – Slingshot Plastics
By far, the most challenging part of this project has been the graphics design. It’s not easy mostly because I’m not extensively artsy. I know good art when I see it, and I can appreciate good art, be it music, visual arts, dramatic arts, etc. But time and again, when I go to write a […]
Read MoreInstalled a Bumper
I managed to install a bumper recently! It’s currently driven by a relay, which is really pretty bad pinball practice. I plan to eventually have a Raspberry Pi driven MOSFET circuit. But meanwhile, check out this video! A simple circuit diagram showing how I used the relay to drive the bumper. It works!
Read MoreHome-Brew Pinball
Build a pinball machine. It indeed sounds crazy, and perhaps it is. But alas, the amazing meld of electronics, mechanics, wood working, and graphic design lure me with every thought. You are probably wondering Why build a pinball machine? And the answer(s) comes in two parts, both driven by geek logic: One, because it’s cool, and […]
