Staver Electromechanical 7 Segment Vane Display

I found these electromechanical vane displays on eBay and accidentally won them. So, here they are!

These are seven segment displays. Each segment is painted a bright yellow and fluoresces under UV light. The segments do not actually draw any power except when they are moved. Behind each segment is a solenoid that flips the segment on or off. Several units are then daisy chained together to form larger numbers. Watch the video below to see it in action and be sure to check out the image gallery.

(P.S. Sorry for the heavy Minnesota accent in the video.)

From Wikipedia:

A vane display is a type of 7-segment display. Unlike LED and VFD  segmented displays, vane displays are composed of seven physical surfaces, typically painted white, but occasionally other colors, such as yellow or fluorescent green. If a segment is to be displayed as “off”, it will be rotated so that its edge faces forward, with the painted surface pointing away and not visible. A segment that is to be displayed as “on” will be rotated so that the painted surface is shown.

Vane displays operate in a similar manner to flip-disc displays, in that the segments are quickly moved using electromagnets. Some variants used where the display need not necessarily be changed quickly use electric motors to rotate the displays in and out of place.

  3. I too would love to get some of these… could you share the seller/company you got these from?

    • Hello-
      I purchased these on eBay but I cant seem to find the seller name. There are currently a few smaller ones for auction – try searching for “flip display” or “vane display”

      Hope that helps!

    I recent was at a Ham Fest in Huntsville, AL and found someone selling the vane displays. Tiny ones. Bare units about 2″ tall. It was new old stock. I have a set of six of them and looking to make a clock. I wanted to mention this to you that I am trying to buy the rest of them from him. I never seen them up close and at this size.

    :)

    Very cool. I actually just 3D rendered one of these things. Needs a little work but it was fun to work on. I’d rather have real ones though. http://www.cantplaypiano.com/media/flipdigit.mov

    Thats exactly what i am locking for to build a clock for my garage. Is there any manufacturer who still produce these 7 segment displays? I found some on Ebay, but in germany.

    That’s much more interesting than a 7 segment display that just lights (or doesn’t light) segments. Very retro.
