Check out HOW TO BUILD A PINBALL MACHINE for material sources, CAD drawings and fabrication instructions...
Retro Spa is a newly-built custom pinball machine,
using a mix of vintage and reproduction playfield machinery (Bally, Williams and Gottlieb) with new microcontroller electronics,
and original artwork inspired by a classic game.
A computer simulation,
with a physics engine and accurate topographical table layout, was used to help develop the game rules, scoring and other functionality.
Like previous custom games, this pinball was designed to look and play like a vintage 70's to 80's machine.
However, the specific challenge for this machine was to show that a wide-body table could be re-designed to standard size while maintaining the features, feel and game play of the original.
As a bonus, the artwork was based on
that were rejected over thirty years ago, making this both an "alternate history" prototype as well as a tribute to one of the all-time-great pinball artists.
, some of the electronic circuits are unique and highly customized, while others are off-the-shelf from PinScore, MultiMorphic or Arduino.
