Circular displays are here! Round screens aren’t exactly useful for productivity, but are too cool to pass buy. Today I’m breaking down a few common varieties to show you how easy it is to get them running with an Arduino, Raspberry Pi, and a regular PC running Windows. All of the displays I've found are linked below.

4d systems - OEM units from Oz, integrated controller with a proprietary, but easy to use language that allows for external control by another host (Arduino libraries available), several flavors available at different price points. Most documented round display I’m aware of.

Pimoroni - Raspberry Pi ready! The st7789 chip is well documented and can also be used with microcontrollers. The Hyperpixel version is easy to use.

I had trouble getting it to run with my setup:(Pi 4 B+ running 32-bit PiOS Oct-30 release), but it was a quick fix

In “/boot/config.txt
“dtoverlay=vc4-kms-v3d” had to be updated to “dtoverlay=vc4-fkms-v3d” to work. See here:

Aliexpress - Larger OEM displays with HDMI input. You can find even more bizarre displays at these stores too, so they're worth a browse:

    I would love to build one in with an ADS-B virtual radar display. So a little handheld device that shows you aircraft within your immediate vicinity based on their ADS-B data.
  • @AtomicShrimp
    Now we a GUI layer for an OS that natively doesn't have corners - Microsoft Circles (except not Microsoft please)
  • @ciromangione424
    the larger versions would be perfect as a speedometer for my '89 Fiat Panda
  • @owiela
    For some reason, the first thing I thought of was replacing the standard car dashboard dials with these! You can position the screens in whatever layout you want, not to mention having customizable speedometer or fuel/battery gauge. You will be able to have a way to add almost any sensor to you dashboard as well.
  • @Lwyte17
    "Call us for a quote!" Breaks my heart every time...
  • @GERMENyOTROS
    A fake telescope, when you move it around you change the view on the display, like that sky app. Excellent ice breaker for visitors. Another more useful idea could be a door viewer, like those little lenses in hotel rooms, but you put a fish-eye cam in your front door and the display in any door of the house.
  • @LisaMiza
    Waow I love the idea of a round themed clamshell phone, that'd be sick nostalgia with a twist! It would require quite a bit of bodywork for it to look and feel like an old phone tho
  • @wyattclove5524
    I think it would be a fun project to find a way to make one of the small ones into basically a wearable pin that you can have a moving picture or even just change what you're showing on a whim, I would wear that all the time lol
  • @TheWretchedOwl
    I keep thinking about how being round makes it seem so… portal like. Like imagine decorating the outside with stones or making it look like a star gate. Then program the pi to randomly connect to twitch streamers or webcam feeds, so it’s like you’ve got a little portal into another world just hanging on your wall. Heck, if you just had it run a game of Minecraft that would look cool.
  • @davidflorey
    These would make a sick upgrade to smart meters for the likes of flight sims, and other equipment where a traditional needle gauge is used, but you want to be able to change the display / meter for different applications!! Also, for really nice looking dash UI's in cars where the speedomoter goes - changing colours to suit the car, the mood, day vs night, etc... Possibilities are endless! I always wanted to do something like this for a car...
  • @sparkyprojects
    You could use the large display as a face of a character in a 'hoodie', the face can be good or evil or trasition from good to evil Though it would be cool if the character could move around by remote control too.
  • @CYDeviant
    They're honestly very pretty. just super eye catching having such a thin bezel and a truly round display.
  • This channel is a true gem. I really look forward to you blowing up. you and your content are engaging and fun. Glad i subbed
  • @572089
    the 3.4" one would be ideal for an instrument cluster. could be a cool dash overhaul if someones swapping in an aftermarket ECU on an older car.
  • @Rouverius
    Hey, these might be great application for playing around with "Anamorphosis" You know, those distorted images that can only be seen properly with a special cylindrical or conical mirror.
  • @StormBurnX
    Oh, as a project idea: absolutely overkill, but you could pop two of the watch screen sized ones onto some glasses, and then mount some kind of HMD on the other side - like, slap these on a vuzix headset or something to give you 'eyes' or something like what Rezz wears! :P
  • @angryhob0z
    Great informative showcase of components!😀 Would love to see more videos like these in the future if you have the need/opportunity in future projects (components, tools, development kits, etc.)! It's stretching the boundaries a bit, but using one of the smaller 1" displays with one of the 5" displays to create a DHD and Stargate that communicate and animate with each other would be pretty friggin epic! (bonus points if you can use a capacitive touch display for the DHD and make it functional as a DHD to dial an actual address on the larger display stargate!)
  • @AntiAntagonist
    I could see these being used for Mechanicus costumes. Rounded shapes also work with art deco designs as well
