Ten Projects Won the Rethink Displays Round of the Hackaday Prize

June 28, 2021 , , , , , , , ,

We asked you to rethink what displays can look like and you didn’t disappoint. From almost 150 entries the judges have winnowed the list down to ten projects which are awarded a $500 prize and will go on to the final round of the 2021 Hackaday Prize in October.

In a world where there’s an HD (or better) display in every pocket, it is the oddball ideas that tend to turn heads. High on that list is a volumentric display that levitates a tiny foam ball on ultrasonic transducers to draw 3D color patterns before your eyes, or the volumetric display shown above that works with a sheet of film and motors. Or how about a take on a laser projected display that uses a phosphorescent screen so that the path of the laser persists, fading in time for the next infrequent update.

Mirrors are a part of everyday life but they’re all limited to the visable spectrum. One of today’s finalists flipped the script and turned the mirror into one the visualizes heat. And we’ll be watching with keen interest as this holographic display project seeks to turn a tube of perspex into a 3D display that can be viewed from any side!

This was the first of five challenges in the 2021 Hackaday Prize and the great news is that these finalists — all of which are listed below — will have until the end of October to refine their designs for the final judging round. Meanwhile the next round has already begun with the Refresh Work-From-Home Life challenge. Show off your solutions to being productive when working (or studying) from home while still preserving your personal life and your health.
