Description

Due to several requests, I finally have fully assembled and tested Flip Clock PCB’s in stock!

For all you retro display enthusiasts and electronic hobbyists – a Flip Clock PCB is the core component you need to make your very own Retro Flip Clock! Simply grab one PCB here and four “7 segment 1″ Ferranti-Packard electromechanical display” units off eBay and you’re well on the way to owning an extremely unique retro clock. I’ve done all the leg work to make using these difficult to drive displays click away perfectly whether on your shelf at home or as a desk piece at work.

Please check out my full build-log and walk-through of this clock here

Features:

• Fully open source and user re-programmable (based on Arduino Pro Mini 3.3V 8MHz)
• Capable of driving 4 Ferranti-Packard Displays at their native 19V operating voltage using a discrete transistor topology
• Genuine DS3231 RTC chip with TCXO and rechargeable battery for extremely accurate and reliable time keeping
• White LED back-lighting
• Easy time setting with two tactile buttons
• Reverse polarity power supply protection
