There really is something satisfying about seeing some old clearly "obsolete" piece of electronic equipment brought back to life. The next step is to find a way to actually use this in a larger piece of gear. If only you had 4 you could make a clock out of it.

On the topic of the switching order: The main solenoid lifts the character plates, which allows the selector solenoids to freely rotate the selector arms. Depressing the selector switch, then lifting the character plates while holding down the selector will cause the selector arms to rub against the selection teeth on the character plates. I suspect the best order of operations for this device would be to depress the switch that lifts the plates (set pulse), then, while holding that, depressing the switch to set the selector arms (bit/signal pulse). Now with both switches pressed, release the switch holding the character plates up, which lets them settle onto the selector arms. Now that the character plates are effectively holding the selector arms in place, the second switch can be released. This order of operations agrees with the description in the manual. The set pulse must be at least 30ms, the bit pulse must be at least 50ms, the time between bit pulse going high and set pulse going low must be at least 30ms, and the time between the set pulse going low and the bit pulse going low must be at least 20ms.
I was wondering if the switch for the selection signal was even "expected"; that perhaps the bit signal would be sent continuously, and then the set pulse would simply display whatever was being requested at the time it was triggered. But I can see the concern that the selector arms could be pressing against the teeth in unhealthy ways.

It’s 15 minutes to 3am. Just finished the video where Fran says “I’m not gonna try to repair it”. Then the preview card pops up with ‘Part 2: I repair it!’. Now it’s 15 minutes *after* 3am. Thanks Fran. 😅
I'm glad you fixed it. This is a very cool display. When you mentioned that someone said you were using the wrong sequence of operation, I think I can see what they meant. When you connect power to set the bits first, then the reset, you energise the coils for the teeter-totters before they can freely move. So the coil end is trying to flip, while the brass plate is still held stuck by the notches at the bottom of the character plates, which puts some twisting force on the rod linking them. I can see how it could be beneficial in the long run to do the sequence as follow: - Energise the reset to lift the plates - Energise the bit setting coils, hold it on - Release the reset to lower the plates - Then release the bit setting coils That would avoid putting any twisting forces on the teeter-totters and also avoid the brass plate scratching at the little knob between the high and low notch of each bit, at the bottom of the character plates. But those probably wouldn't have any significant effect on the life of the mechanism.
Y'know, with so many unused addresses in there, all you would need to do is find a metal sheet of the right thickness and a laser cutter, and you could design and build additional glyphs for that beauty!
There's only space for maybe 4 or 5 additional plates though. The full 64-character versions (if they even existed, the order sheet doesn't seem to imply anything greater than mid-40s) would have needed a longer "rack" for everything to sit in. But that'd still be enough for the old J, K and L Wingdings... And the resolution is enough that it should be possible to just about construct a readable "Fran [Lab]" logo, with the two words vertically stacked.
Yeea... I knew you could do it. All 40 plates now accounted for. The border was kind on surprise to me. Maybe back then it kind of acted like a cursor location if you had a big array of BV units as a display. Thanks for the great video!!
Exactly what I was thinking ... or at least, what I was thinking when Fran first said "interference display". The truth of it wasn't quite the same as what I expected! The Kinos (and their smaller equivalents used as the alternate history version of a powerpoint projector or computer monitor) were, as I dimly remember, rather more like macro versions of the DMDs in DLP projectors, or really intricate, high rez, high update speed (and almost certainly insanely expensive, complex, and loud) versions of an EM flip-dot signboard. Or Terry Pratchett's (also rather based in reality) binary light-matrix "Clacks" semaphore telegraph, which does the necessary thing of combining the two ideas in a Binaview way to produce an output pattern from a single incoming light source (well, in the daytime anyway... using the sun... at night, a bunch of high intensity oil lamps, thus becoming a weird OLED/Plasma-and-LCD hybrid).
I think the datasheet actually tells you to activate the data and latch at the same time. After 30 ms you release just the latch (causing the selected plate to drop) and after another 20 ms you are free to also release the data. The way you did it (first energizing the data) shouldn't impact the way it works, it just wastes the power you put into the data-coils before you activate the latch.
Another option is to pulse one bit at a time, 30ms each, then release the latch. To interface with tube systems, the 6.3V bulb can be driven by the cathode heating voltage while the 24V solenoids are driven from tube-switching 26V power rails. (Tubes are similar to FET transistors). For electronic interfacing, a 2N7002 chip can control all 7 solenoids from TTL level signals like an UART chip or an Arduino, The Arduino could do the ASCII to bini character mapping and control the timing to display something like a chess move or code ID. But so could a small pack of 74xx chips, with a pair of 74121s providing the master pulses fed to and gates. Perhaps a diode matrix could form the core logic and mapping table, with some 22 pin 4-to-16 decoder chips decoding incoming bytes to ROM columns (3-to-8 decoder chips would be needed in larger quantity, a diode logic column selector would need a bunch of inverter/buffer chips). Diode logic obviously needs germanium transistors to stay within the 0.4V margin between 0.4V low outputs and 0.8V low inputs.
Interesting note, the Nimo tube and the Bina-View were both products of the same company, Industrial Electronic Engineers (I.E.E). And as some else stated it's still in business today making what else ... Displays.
Kind of reminds me of the 'belt sign' we had at the Army Recruiting Center when I was a recruiter. It had a 6 inch belt with holes punched it in to allow the light through, the belt ran in front of a green florescent lamp and said witty things about the Army, like Fun Travel Adventure ARMY and so forth. Not as complicated but it worked back in 1977.
Electrowave I wouldn’t call this “simple.” It’s not complicated compared to, say, a DLP projector-one of the most complex electromechanical devices ever. However, to come up with the concept and figure out the implementation was very clever. Some nice mechanical engineering going on. The electronics are simple.
@@ebkesq72 I probably used the wrong word there. Yes, clever mechanics like this take some designing and I love them because I can see what is going on inside when they operate, unlike the little black blobs that control everything now. By simple I meant I can see everything and every little part I can see is a simple thing, like a solenoid, a lever, etc. As a whole it is a very cleverly made device. I'm not good at explaining myself but hope this explains a bit better :-)
I suppose you could argue that an IC is simple when broken down into transistors but you can't get into them with a screwdriver, take them apart and put them back together in such a way they still work or work better.

@@markpenrice6253 Yet another bit of evidence that "GIF" should be pronounced "jif".
@@markpenrice6253 Also, the internal timer clock unit in UNIX/Linux is a jiffy, and was original HZ=100 .
It’s 15 minutes to 3am. Just finished the video where Fran says “I’m not gonna try to repair it”. Then the preview card pops up with ‘Part 2: I repair it!’.
Now it’s 15 minutes *after* 3am. Thanks Fran. 😅
This display is so freaking cool! I'm glad you got it working, it is an amazing piece of early tech!
This is really a beautiful device. Digital displays from the pre-digital era are really fascinating.
Like I commented in your first video, I saw that last rail not actuating right, glad you found it!
What an incredible display device! I wish their were more like it.
Phenomenal! So glad we got a 'deeper look' into this fascinating display! Thanks Fran, you're amazing!
It's amazing what you spot on camera. I had no clue, but could see that flange was lower than the rest and not engaging 😀
Really cool display. Nice looking font.
@Fran Blanche, You are awesome! Thank you for the video, keep up the great work and have yourself a great rest of the week.
What a Frantastic result! Great job!
So satisfying! thanks for follow up and working through the fix!
Wonderful! Great to see stuff like this. Well done and keep going Fran !
Excellent! What a mind blowingly complicated device. But oh so cool!
I knew you'd get it working. Well done. And like so many others here, I too was yelling at the TV about bit 32 being too low. LOL.
Fran you are a genius
Marvellous stuff, well diagnosed Fran.
I'm glad you fixed it. This is a very cool display.
When you mentioned that someone said you were using the wrong sequence of operation, I think I can see what they meant.
When you connect power to set the bits first, then the reset, you energise the coils for the teeter-totters before they can freely move. So the coil end is trying to flip, while the brass plate is still held stuck by the notches at the bottom of the character plates, which puts some twisting force on the rod linking them.
I can see how it could be beneficial in the long run to do the sequence as follow:
- Energise the reset to lift the plates
- Energise the bit setting coils, hold it on
- Release the reset to lower the plates
- Then release the bit setting coils
That would avoid putting any twisting forces on the teeter-totters and also avoid the brass plate scratching at the little knob between the high and low notch of each bit, at the bottom of the character plates.
But those probably wouldn't have any significant effect on the life of the mechanism.
Excellent - glad you couldn't leave it alone!
Learning letters and numbers feels like sesame street all over again. :-)
Y'know, with so many unused addresses in there, all you would need to do is find a metal sheet of the right thickness and a laser cutter, and you could design and build additional glyphs for that beauty!
Smiley faces? Emoticons? It could be your workshop mood indicator. :D
There's only space for maybe 4 or 5 additional plates though. The full 64-character versions (if they even existed, the order sheet doesn't seem to imply anything greater than mid-40s) would have needed a longer "rack" for everything to sit in. But that'd still be enough for the old J, K and L Wingdings... And the resolution is enough that it should be possible to just about construct a readable "Fran [Lab]" logo, with the two words vertically stacked.
Awesome! Very satisfying to see it working. It would be cool if you could build a project around this, perhaps a countdown timer or something?
I like how they use smaller holes for anti-aliasing to make the character edges look nicer.
They really do look smooth!
@@originalveghead It's really noticeable on the "7".
@@AntonyTCurtis The numbers look very clean, did not expect that
Nice one, I did not realize it is anti-aliasing indeed.
There is supposed to be a diffuser at the front, she took it off as the bulb is 28v on a 24v supply and it wasn't bright enough.
Yeea... I knew you could do it. All 40 plates now accounted for. The border was kind on surprise to me. Maybe back then it kind of acted like a cursor location if you had a big array of BV units as a display. Thanks for the great video!!
What are you doing with me? What am I watching here? Fran, you make me a fan. Thank you for your great content.
Congrats on the repair!
This reminds me of the "kino" theater screen in "The Difference Engine" by William Gibson.
Exactly what I was thinking ... or at least, what I was thinking when Fran first said "interference display". The truth of it wasn't quite the same as what I expected!
The Kinos (and their smaller equivalents used as the alternate history version of a powerpoint projector or computer monitor) were, as I dimly remember, rather more like macro versions of the DMDs in DLP projectors, or really intricate, high rez, high update speed (and almost certainly insanely expensive, complex, and loud) versions of an EM flip-dot signboard. Or Terry Pratchett's (also rather based in reality) binary light-matrix "Clacks" semaphore telegraph, which does the necessary thing of combining the two ideas in a Binaview way to produce an output pattern from a single incoming light source (well, in the daytime anyway... using the sun... at night, a bunch of high intensity oil lamps, thus becoming a weird OLED/Plasma-and-LCD hybrid).
Please make a proper driver board so it can display some text. The sound should be great if it switches way faster.
On page 8, it says you can connect up to 4 together!

Well Done Fran, Awesome job !!
Glad you decided to fix it!
Just seeing this tonight. Awesome work!
Great job on the fix !
I think the datasheet actually tells you to activate the data and latch at the same time. After 30 ms you release just the latch (causing the selected plate to drop) and after another 20 ms you are free to also release the data. The way you did it (first energizing the data) shouldn't impact the way it works, it just wastes the power you put into the data-coils before you activate the latch.
Another option is to pulse one bit at a time, 30ms each, then release the latch. To interface with tube systems, the 6.3V bulb can be driven by the cathode heating voltage while the 24V solenoids are driven from tube-switching 26V power rails. (Tubes are similar to FET transistors).
For electronic interfacing, a 2N7002 chip can control all 7 solenoids from TTL level signals like an UART chip or an Arduino, The Arduino could do the ASCII to bini character mapping and control the timing to display something like a chess move or code ID. But so could a small pack of 74xx chips, with a pair of 74121s providing the master pulses fed to and gates. Perhaps a diode matrix could form the core logic and mapping table, with some 22 pin 4-to-16 decoder chips decoding incoming bytes to ROM columns (3-to-8 decoder chips would be needed in larger quantity, a diode logic column selector would need a bunch of inverter/buffer chips). Diode logic obviously needs germanium transistors to stay within the 0.4V margin between 0.4V low outputs and 0.8V low inputs.
Fantastic fix Fran.
Interesting note, the Nimo tube and the Bina-View were both products of the same company, Industrial Electronic Engineers (I.E.E). And as some else stated it's still in business today making what else ... Displays.
very cool, this device is fascinating, something about this is super exciting to see you get into, thanks for going through it
Great job Fran, cheers!
Kind of reminds me of the 'belt sign' we had at the Army Recruiting Center when I was a recruiter. It had a 6 inch belt with holes punched it in to allow the light through, the belt ran in front of a green florescent lamp and said witty things about the Army, like Fun Travel Adventure ARMY and so forth. Not as complicated but it worked back in 1977.
Like one of those scrolling LED signs, but with a physical scroller?
This is very satisfying! Glad you had a stab at it after all.
Thankyou Fran... i am sure curious mark would love to get his hands on that display..
glad you were able to get it fixed.
Hi Fran! congrats!
Simple and functional and repairable. Got to love the older equipment :-)
Electrowave I wouldn’t call this “simple.” It’s not complicated compared to, say, a DLP projector-one of the most complex electromechanical devices ever. However, to come up with the concept and figure out the implementation was very clever. Some nice mechanical engineering going on. The electronics are simple.
@@ebkesq72 I probably used the wrong word there. Yes, clever mechanics like this take some designing and I love them because I can see what is going on inside when they operate, unlike the little black blobs that control everything now. By simple I meant I can see everything and every little part I can see is a simple thing, like a solenoid, a lever, etc. As a whole it is a very cleverly made device. I'm not good at explaining myself but hope this explains a bit better :-)
I suppose you could argue that an IC is simple when broken down into transistors but you can't get into them with a screwdriver, take them apart and put them back together in such a way they still work or work better.
Nice show and music, will patreon soon, enjoy watching your show, stay safe!
This is exciting device! This is real digital electronics. Totally dark electronic waters for me. Thanks for vid.
The mechanical binary "decoder" is the sexiest thing I've ever seen.
