HowTo: Write in Midair with LEDs

Feb 28, 2010 05:30 PM

Hacked Gadgets recently featured Csaba Bleuer's LED wave display, a device that projects LED messages midair. Bleuer had also previously created a similar device that spins on a fan motor.

"Csaba Bleuer sent in some pictures and a video of his new creation. It is a LED Wave Display, you just wave it back and forth and text is displayed in mid air.

You might remember the Fan Motor Spinning LED Display of his that we featured here in the past. If you think this device looks similar you would be right, he took the display from the spinning display and mounted a 4 X AA battery holder to it, mounted a small circuit board onto the new device and made a switch that detected motion to the top. 

If you would like to make your own Csaba has made the code available."

Check out both of Bleuer's LED wave displays below.

The next big software update for iPhone is coming sometime in April and will include a Food section in Apple News+, an easy-to-miss new Ambient Music app, Priority Notifications thanks to Apple Intelligence, and updates to apps like Mail, Photos, Podcasts, and Safari. See what else is coming to your iPhone with the iOS 18.4 update.
