I am pretty new on this forum, as most of the time on the other side of Atlantic ocean
I am the owner of a 1975 Gottlieb FastDraw pinball that I have almost fully restored. It is now playing like a charm on a clean and neat playfield !
As I am a "electronics geek" I wanted to add something to my pinball but without destroying anything into the original wirings.
Here is what I made : A Bluetooth Low Energy clock synchronized via Wifi with NTP and connected to my Android phone for tuning.
The clock directly moves the score reels to display date/time and rings the bell (chime)
It connects on the backglass side directly on the connectors. The pcb is hidden into the cabinet and protected by a nice wood cover specially designed by "french tech industry" !
Videos are here (sorry in french but easy to follow !) :
