Continual Shows with UV Mild

This 12 months’s Prize has “Reconsider Shows” as one of its first theme, and [Tucker Shannon] has given us his perfect shot on that matter with a collection of spectacular shows that “write” on glow-in-the-dark subject matter the use of ultra-violet mild. Those fabrics glow for some time after UV illumination, so transferring a gentle supply like a UV LED over the skin attracts sparkling textual content or easy graphics which will also be readily ate up.

(*3*)(*1*)One of the crucial examples this a clock we had been first smitten with again in 2021. This can be a somewhat horny Three-D-printed affair with the ones servos fastened under the display screen that strikes a UV LED via a couple of linkages. Different choices that play at the similar UV stylus medium come with a laser on an az-el mount managed by way of a Raspberry Pi 0. It’s a neat concept very successfully achieved, and we will see it has numerous attainable.

However essentially the most impressively complicated to this point is the type proven within the symbol on the most sensible of the thing and the demo video on the backside. A loop of phosphorescent subject matter is the show floor itself. This one strikes that loop with two rollers to make up the X axis, and strikes the UV supply up and down for the Y axis. As with any of those designs, no matter is written will quickly fade, leaving the skin in a position for the following bit of data.

on this venture and suppose that you must do a show of your individual? The Prize 2021 is are living, and we’d love to peer you input it!
