You may argue that the mission to add a round screen to a Raspberry Pi from [YamS1] isn’t strictly mandatory. In spite of everything, you might use a sq. show with a masks round it, giving up some display screen actual property for aesthetics. Nevertheless, you’d nonetheless have a sq. form across the display screen and there’s one thing eye-catching a couple of small spherical display screen for a watch, an indicator, or — as on this mission — a speaking head.
The inspiration for the mission was a quote from a Google quote about teaching a monkey to recite Shakespeare. A 3D printed monkey with a video head can be onerous to do effectively with an oblong display screen, you need to admit. Potential with somewhat artistry, we're positive, however the spherical head impact is tough to beat. Truthfully, it seems extra like an ape to us, however we aren’t primate specialists and we predict most individuals would get the concept.
The IPS display screen is tiny at only one.28 inches and has a 240×240 decision. Interfacing is straightforward with an SPI interface. You’d assume video playback is perhaps powerful, however the flexfb library is aware of the right way to drive these. The one downside is the library isn’t suitable on Linux kernel 5.4 and past.
To unravel that downside, [YamS1] used a Raspberry Pi 3 with a selected software program load. For a devoted gadget like this, that shouldn’t be an issue and provides you a superb excuse to recycle these older Pi boards you've gotten sitting round.
We’ll be sincere. You in all probability don’t need a speaking monkey sculpture in your desk. However should you do, that is your fortunate day. Nevertheless, the probabilities for a spherical display screen are quite a few and one that may play video has much more usefulness. Possibly the factor to your subsequent robotic or cosplay masks eyes or why not 3D print a tiny reproduction of a classic oscilloscope and use this show for the CRT? In fact, a smartwatch is simply too simple however would work, too. You may additionally make some very cool replacements for magic eye tubes.
