Flip Disc Clock and Controller

[Shaun Merrigan]

Folks,

Just received an email from Marcin Saj about his new project involving Flip Disc displays.  He has everything from bare displays to prototyping boards to complete clock kits available on Kickstarter:

Looks interesting and cool!

Thanks for that Shaun, Marcin's projects are always fun and interesting.

Cheers,

Nick

Oh no, more money to Poland! He's already taken me for plenty.

How's the Euro this week? My timing was good the last time around.

Great job on the mechanical section, Marcin. These look like production-quality items, not something that was 3D-printed in a rush.

Why stop on a seven segment display ???  with 1/3 more dots, you can have a 5x7 dots matrix, that can display almost all characters...

Pretty cool.  Reminds me of the old flip displays used in airport boards or currently in products like the Vestaboard ($$$$$!).  The TWA Hotel at JFK airport built in the old TWA terminal building still has their two original boards which are really cool.

Just one observation from when I built a one-off flip clock years ago using some salvaged vane displays.

  Just be aware of the mechanical noise associated with these things.

   The sound from the flips can be pretty mesmerizing (like falling dominoes) and part of their appeal,  unless you are trying to sleep.

    Had to add in a timer function to turn itself off during the night.

Many years ago I got to know a service technician who worked on these displays wherever they were used, he told me that apart from making sure that all vanes ended up in the same reset position many systems used a flowing setting routine that passed from one side to the other not just to minimize the electronics used but it also made a "sweeter" noise when all vanes rippled like a wave ,rather than being set individually letter by letter, which people liked more. This was more common on train/bus stations for larger displays but single row displays used it too.
