Our editors have compiled a list of the “Top 5 Strangest LED Projects” for your enjoyment. Which ones are your favorites?
Honorable Mention – Programmable Spinning LED Fans
Polo Tech takes the idea of a spinning LED fan to a whole new level of customizability — allowing users to program messages and other text via USB. This patented technology consists of “a rotating circuit board with a vertical array of LEDs attached” that “uses persistence of vision to display the graphics”. [Source]
5. Giant MP3 LED Display
To build your own nifty “Giant MP3 LED Display”, you’ll need lots of 128×64 two-colored LEDs, approx. 80×40cm panel, 110A/5V = 550W power input, an Ethernet interface, and a 16-MHz ATmega128 processor. Full instructions here.
Again, this was such a crazy project for me. It began with the mountain of LED modules I bought off eBay. And from this this enormous pile of LEDs came this panel
4. 32 RGB LED Magic Ball
You may have seen these cool — but sometimes annoying — LED devices before, so why not make your own?
This one was made using a Microchip 16F628 microcontroller and serial to parallel converter chips since the 16F628 doesn’t have 32 outputs.
3. LED Touch Sensor
JustDIY proves that LEDs can be used for more than lighting, but also as an input device.
This is a collection of the work I’ve done with using the bi-directional properties of LEDs. I have also included links to information I’ve found on the subject and the project by an NYU research that inspired me
