It would be great to see some home made efforts now with so many amazing off the shelf bits of tech and 3D printers.
The site is also a nice compliment to the Technology Connections series on old pinball machines [1].
It's absolutely fascinating how concepts like score are implemented purely in electromechanical circuits (that is, motors not motherboards).
Then my mother found out about me "stealing" all that cardboard and my days of pinball manufacturing where over...
Honestly one of the happiest weeks of my life!
