- I got a flip dot display from the viewer and the chat let me build an oscilloscope out of that within a livestream. We were successful and I continued to design a driver board to make it nice...

Wow! I just love what you made out of this!
Ladies and gentleman. This is the generous donor of the display.
Thankyou for feeding the Bitluni !....cheers.
@Jakob Landerbrecht our startup here in Tokyo is very interested in your display. Do you make them yourself?
I NEED ONE!!👍
Diy or buy 😆
@@jeffberhow I know of only one place to buy, and based on the effort that may be a bit pricey
Send me one of Ur lab equipment
Agree
wtf u are here too😂
It's interesting that even flip-dots are not immune to "screen burn-in". At 10:57 you can see the ghost of something like "857" on the display when all the dots are yellow. I guess these were the most exposed dots during the life of operation. Great project, and one that's been on my list for quite some time too!
Maybe they got bleached by the sun
This suggests it was used on a bus
The snapshot function is simply to yank out the power. Genius!
It may be the worst oscilloscope but it is by far such a fun looking project. 10/10 mate.
You can make a oversized DLP projector out of this :D
You'll just have to make the dots reflective using aluminium tape or something.
I just need to glue on 400/800 mirrors... sounds like something I'd actually do
@@bitluni you are really great, man! thank you for this wonderful contents :D
@@bitluni use a modded pnp machine
I was just searching for DLP chips and this thought hit me. I thought I'd add it as a comment. Amazing to see it's only the third comment down.
@@bitluni You're awesome!
This reminds me of all of those people who used multiple accounts, biluni working for over 13 hours (LEGEND!), And the amount of people requesting a 'pink LED'. An awesome stream!
Wow, your "production" quality vent up quite a bit, really nice! Now both production and projects are extremely high level.
Love that Aisler sponsors this! They need to be used by more people, especially in Europe!
Yes I've just registered, finally sponsor worth supporting!
I have used aisler once. I got 5 boards. They told me there was a short on one board during flying probe test. Then they proceeded to send all boards to me in one stack without further info on which board was faulty... It was also worse quality and more expensive than JLCPCP
@@hansdietrich83 I haven't had any problems with them until now, however I agree that they are expensive, but the advantage is that those are locally produced PCBs (at least for me) and I trust them more with my design than I would trust any chinese manufacturer.
@@hansdietrich83 I suppose that's the price you pay if you want manufacturing to be returned back to Europe. They are a bit expensive unfortunately.
I had good success with aisler. Nice matt finish, good quality boards. Since I live in Germany, shipping is very cheap and fast. For small one off prototypes, prices are competitive.
Wow. Incredible. What a fantastic idea / project / video. I love it!
Nothing better than hearing your triumphant excitement when something works. :) Love this project.
It's great and I'm sure there's many things you could do with it. Thanks for all the hard work and time, it's very inspiring.
I am hugely excited about this video!! I have 4 of exactly the same displays and never got them to work. Now I got new hope to eventually reach enough knowledge out of your video + documentation to finally get them to flip again! Thank you! P.S.: Mine came with daughter-boards that look a bit like yours (whole lot of DIP ICs) but I don't have enough skill to reverse-engineer them...
I just dumped the files on github but would need to add some documentation. The BOM cost is quite low
It's still very cool as a display project! Flip sound is great, when multiple relays clicks at a same time.. 👍
Add to it feature to show RUclips subscribers count between logo and scope slides.. 😉
Aisler is fantastic, I really love their service!!! Very recommended.
Bitluni, cool idea. Liked the video
The sound is so cool and funny
Absolutely brilliant idea!
It's nice to see some know names amongst your Patreon. Applied science in example
This is a really cool project!
Well this is really cool! I love it!
Super project 👍😁👍
Flipping awesome, dude!
Makes me want to finish my flippy projects! I have about 5 flip dot displays waiting now.
Slick video and a great stream.....cheers.
I would try to turn this into a streaming video player. An oscilloscope is just too useful.
Those clickety clacks are just EPIC!
Definitely need to turn this into a Pong game.
Nice work
Really good .... not the least part the 3D printed housing!!!!
Extremely accurate oscilloscope 😀👍
I love it.
It's really not fair to the rest of us how awesome you are. :P
You need to play pong on this 😂
Great build, want one of this 🙂👍
hmmm BT Controllers should work
Great :-) -- next video ?
Also, tetris would be a nice game for that dot display ;-)
I can easily imagine one of these on bigclive’s shelf 🤣
Amazing!
An serious oscilloscope needs buttons! And an easter egg function like ... say ... Tetris! ;)
Plz make some videos about making Oscilloscope using esp32
Great risetime
Better than anything I've ever made 👌😁😁
Make flip dot displays great again!
8:59 **FLIPS THE FLYPPY THING**
I love it
Great project! I notice the display has some burn-in, presumably from UV light getting to the pixels most used for its former life in a train-station display perhaps?
I remember making an oscilloscope using led panels. The project was in 'everyday and practical electronics' magazine in the eighties, I think. I was so proud, but it was quite useless.
Watching that oscilloscope feels like IRL lagg 😂
Next, make a bigger one and play doom with it!
lol... the snippet where someone suggested running doom during the stream, didn't make it in the final cut. The audio was too bad :-C
Moar flippin dots please. This is wonderful.
Awesome random project. Did anyone else read "Bitlunis Flippy Flip" in Ozzy man reviews voice?
Hi just wanted to say I enjoy watching your videos.
A couple of weeks ago I sent an email asking about you LED Wall.
Was trying to get information on the large black boards you used.
Was wondering if there is any way of purchasing the boards as assembled (as seen in your video when you received them).
Being a novice, thought it would be a quicker learning with the electronic side completed with the boards you designed working with my design use.
Thank you in advance any information regarding this.
I think we should officially call it a FlippyScope 😄
Native QR code display!
It is useless, and so, becomes essential!
Make a WiFi Clock out of it, that would be so annoying! 😂👍🏻
Yeah with milliseconds display
🤣🤣🤣 you have a good delirium!😜🤣🤣
You have a lot of patience.
Mantap Mang. Bagi 1 dong.
Can you please add a command to clean display in your esp32 VGA out library. As it will be very useful for displaying moving data on screen.
nice!
Huzzar! You've been to a barber!
18 seconds in, already hit like.
Would do twice if I could.
Unfortunately premature likes aren't counted by the algo 😅
@@bitluni lol awwww nuts!
Hopefully the comment will help with the engagement algo ;)
Great project man! Just the perfect amount of "stupid" XD Love it!
one of the best projects ever, beside the almighty fail thingy ... enjoyed those streams very much. #PinkLedRules
Wish-list Video : The cheapest CNC Milling Machine that could mill a human Head....
This is no ordinary dispaly this have another dimension plus.sound dimension.just imagine wall clock with date and name overflipping.,🥰.I call this :must have thing.!
You forgot to mention that your oscilloscope has a builtin memory function and that cosmic rays wont flip your pixels :D
yeah.. it's persistent and the regarding the cosmic rays it depends on the particle size
I though about a massive corona emission from the Sun , that should be enough to magnetize any wire , the those tiny wires in the coils
Can you make a digital clock with that?
I wonder what a glass tray with some ferro-fluid would do on top of one of those without the "flippy" bits?
ruclips.net/video/5PFgVtzsXHM/видео.html
super
you could use microsoft witheboard instead of paint for collaborative drawing
Yo you should totally hook that up to an old NES and try to play Mario on it! 😂
You'd have to write some code to interface the video objects to the flip dots, but that could be fun too! Probably be easier to use an emulator, and somehow separate the background and foreground objects in the game and then only display the foreground objects (like Mario, pipes, blocks, enemies, but not the scrolling background sky images).
How much power does it draw? It's such a readable display I don't understand why they stopped being popular outside of airport terminals.
A flip dot is much more expensive than an LED. As for power, it's more complicated than that. If the text was never changed, then the flip dot display would be infinitely more efficient than current displays (excluding electronic ink).
@@userPrehistoricman Yeah E-Ink is cool. I bought 100k displays for a product I sell. But flip-dots are function and art in one. Even the sound they make is very pleasant - like a thousand pixies all flipping a switch inside their tiny capsule homes.
We witnessed a few technological revolutions like that. In that case it was the development of highly efficient LEDs.
I'd compare it to CRT: You love it once it's obsolete
cool
This is nice. 😂😂
HA HA!! great Video and funny :-)
I am trying to get a 14x28 flip dot display to work and with an arduino, I have the arduino wired up to a RS485 converter module. I have 24V going into the flip dot along with the RS485 connection. All my frequencies line up with my program and hardware. Is there something else that I am missing? I cannot get it to work for the life of me.
Can you place a tray overtop and pour a thin layer of ferrofluid liquid into it?
Make a very cool display.
first time since pandemic started. Finally someone noticed ;-P
i watched the live stream of this 😅
This display was evaluated by Moore Reed Ltd in about 1979. They did not proceed,
5:45 I have lost days to this kind of thing.. 😭
Hi @bitlini, can I suggest you something? I'm sure you know propeller clock, right? What about propeller oscilloscope?
F*ck the oscilloscope, I want that flip dot display
Still better than my shitty multimeter!
As a wireless multimeter display was another suggestion by the live chat
@bitluni could you give credits the the creator of the flip-dot display?
My startup would like to purchase a few for a project in Tokyo.
Dumb concept but incredible implementation. Seems like it really works exactly as one would expect. I wonder if there's some value in using this machine as a demonstration of signal 'aliasing'.
Bitluni can i please have some help with you esp8266 altitude logger?
Love it, where can I buy one ?
unfortunately there is no source for these displays and if you get one it is most probably not compatible
espcam?
Utterly useless... I LIKE IT!
Can it process any kind of oscilloscope art?
Tronicfix channel guy looks just like your brother. Are you related?
Make it an X-Y scope!
How well can it handle 1MHz signal?
Stunning 6 Sa/s
Did you try out altium designer?
I try using free tools as much as possible to keep the projects accessible. I wouldn't mind to try if I had to tackle a complicated project.
Hey bitluni,
Wenn du Interesse hast, ich arbeite in einem Verkehrsbetrieb und wird haben noch alte Flipdots, teils mit LED Beleuchtung rumliegen. Würde mich freuen wenn du damit was anfangen kannst und etwas interessantes draus bastelst
JA BITTE! Bitte Kontakt über meinen Discord oder email aus den YT Kontakt infos aufnehmen. vlt kann man eine schöne Kunstinstallation daraus bauen.
This is horrible and I need one!
A mechanical micro mirror
Worst? Nah! Best? Maybe! 😀
***Screen tearing* _INTESIFIES_ **
Flip dots make anything way cooler.
Integrated DC-DC converter was no option? Wasting that much energy is not only lazy but also a very bad practice.
It is an option. I showed a possible substitute. The current scalper cost for this part would double the BOM cost. I will replace it at some point
Has anyone worked out how to make a cheap DIY flip-dot display, because it looks like it's unobtanium.
you can't imagine how long I was thinking about this. You can probably print the dots but the coils is just copper and labor. Even if it ends up costing 1$ per pixel this display would cost 400 bucks
@@bitluni Maybe you could have a single row of coils and then mechanically scan it across the entire display. It would probably end up being much cheaper for larger displays.
@@bitluni I fell of my seat when you said $400, so I looked it up and they are way more than $1 on Ali. I guess a 3D printed base with 400 bolts poking through, then it's hand winding 400 coils - lol -.
No, it's the best.
