The first of many videos coming from the massive donation of amazing hardware from viewer Matt Wietlispach - this one is a bucket list display item that I always wanted to get but could never find. Enjoy!

Used to have hundreds of these type Displays on old equipment at work. Unfortunately I was not involved in the decommissioning and scrapping of the equipment or I would have harvested a bunch of them. They were the older style incandescent type. The display panel also had some 7 segment displays but I think that they wanted larger numerals. I don't know how many different sizes of LED 7 segment displays were available in the mid 70s. I believe the tiny bulbs ran on 5Vdc….
Wow how cool are those displays and thanks Matt for the wonderful donations !
Fran might be interested in this research to reverse hearing loss:
"The biotechnology company Frequency Therapeutics is seeking to reverse hearing loss — not with hearing aids or implants, but with a new kind of regenerative therapy. The company uses small molecules to program progenitor cells, a descendant of stem cells in the inner ear, to create the tiny hair cells that allow us to hear"
– Reversing hearing loss with regenerative therapy
MIT spinout Frequency Therapeutics’ drug candidate stimulates the growth of hair cells in the inner ear.

Looking forward to the 8-ball video! I've long been curious about how those things worked.
It would be cool to see those displays with blue LEDs (since they were unavailable in the 1970s although RCA invented one in 1972, the project was scrapped before something marketable was available). I remember, as a kid tinkering with electronics (1975), I had a grand idea to make a flat screen tv with LEDs, but, to my disappointment, I had to be told by an old guy at Radio Shack that they did not exist!
I'd love to see you pass a small light over the front of that display while recording video of the back of it… Or even to just light up one LED at a time and show the front (or whatever other hybrid on the theme.)
Fun! I kinda want to hand-build one of these sometime, just for fun. But yeah, trying to do mass production? Seems like a nightmare!
Try replacing those old LED's with modern high intensity LED.
And I'll have to disagree about your comment about the front being the most expensive, I'd say, as it is military, the associated paperwork would be the costliest part.
Really neat number display. Could you shine a light though the back of each bundle? I'd love to see which segments are bundles of 3-4-and 5 fibers. Can't wait to see what else is in the haul.
Love it!! Blue led would make it awesome!
I was going to school in Raleigh when they made Brainstorm.
Wow, nice, Matt! :O
I'm not sure if would be as hard as you think to make them it's not really all that much different in basic principle as to how dot matrix printheads are made.
