Flipdot display with drawing, games, etc.

Here's the cleaned-up version of my flipdot display (made by Alfa-Zeta Ltd.). I use my custom Android app to draw to it, show the time, and play some games. The display is driven with an Arduino with a bluetooth serial port, and I send commands to it with my phone.
Some technical details about the build:

Excellent work. That's an impressive display. I love the cyberpunk quality of flip-dot. It would be perfect display for anyone making an electromechanical relay computer. It might be interesting to get some tetrahedral shaped elements and color the sides black, red, green, and blue and see how the dithering effect would look to create a range of colors. I like your version of Life. I wrote one for the IBM PC ages ago. Mine was the only version until that point that allowed saving and loading shapes. All good wishes, bro. I have subscribed.

Help I fall in love with this kind of display

That is cool infact beyond cool! Wish I had a Flipdot sign and was able to do this with it

Thtas amazing :) I love all kinds of displays, those flip dot ones are really cool. It was nice to see you made the Game of Life too, Ive actually been programming the game (well, the algorithms for finding the numbers for the neighbour cells) on arduino for WS2812b strips (I only have 1m 60LEDs) but I'll probably buy more and make a 30x19 display, thats what resolution I programmed the game for. Using bluetooth is a really good way to set the initial conditions, I hadnt thought of that, I was thinking of a joystick type controller. In any case, amazing video! And that cube rendering is very interesting.

Glad you like it! My next project will probably involve LEDs. They're certainly cheaper than flipdots! You can get 32x16 modules for about $35 on eBay. Haven't decided what I'll do with them yet, but I'll think of something.

where can I download your custom app? i don't mind paying.

I have just got one of these displays this is amazing but I have no idea where to go from here?! Can you recommend what I need to do from here? I have a raspberry pi finding it really hard to find real info on the process I’m a amateur but want to learn

love the "NOPE". Nice project

This technology could be useful with laser optic logic gates when the flip dot blocks or mirrors the laser the state will change.

Could you please show how you did this, I can't find anything on these flip dot screens other than some companies that want to sell huge signs at huge cost without any programs or controllers ect

+Mr. Transit Authority I added a link to some technical details in the description. The displays from Alfa-Zeta use a standard RS-485 comm link, and there are any number of ways to connect to that.

That's really fast! What's the refresh rate? I have a 196x16 flip-dot display, but it refreshes at just 1Hz

@spcutler 3 жыл бұрын

It's been a while, but if I recall right the effective refresh rate is about 20 Hz. I remember hoping to get partial grayscale by flipping rapidly, but it didn't work; the rotation of the dots isn't rapid enough. The bus speed is 57600 baud, and at 28x14 pixels I can update at around 120 Hz. But as per above, the dots don't actually move that fast, so only objects that persist for several frames will be visible at that speed. Not sure what the limit is with your panel, but it might just be bus speed. Maybe you're running at 3200 baud or something.

@@spcutler Thanks for the reply Scott. Yup, it runs at a paltry 4800 baud which I'm pretty sure is the max it can handle. In fairness, it was only designed to display the next stop on the bus route :-) You can see it here kzfaq.info/get/bejne/bq94q7ue3N3Vh6M.html

@@iandavidson99 Awesome! Nice work with those lo-fi, retro logos. I agree that it probably wasn't built to play real-time games on :-). Still, I wonder if it might have some kind of high-speed mode, or the ability to access submodules independently. My display is actually two 28x7 displays daisy-chained. If I were baud-limited for some reason, I could have split them into two channels. Maybe yours is similar.
