LED Headgear Is Marvel Of Free-formed Circuitry

July 17, 2011 by 6 Comments

Hackaday contributor [Nick Schulze] popped out an impressive set of LED headgear for a hat-themed party.

[Nick] is no stranger to working with LEDs. Previously he built a blue 8x8x8 cube something like this other 512 node full color version. He had a bunch of LEDs left over from that project and decided to put them to good use.

The first part of the build is the frame itself, made from thick fencing wire. He just started bending it around his head and got an uncomfortable head-shaped hoop to which he could solder. From there, enameled copper wire wraps its way through the system, supplying logic levels to all of the LEDs. Everything is done without a circuit board of any kind. The LED drivers themselves are attached by first using a zip tie to affix a resistor to the frame, then by soldering the TLC5916 chip to that resistor. Even the ATmega8 is included dead-bug style by soldering it to the frame which we think servers as ground. Program it with the free-floating female pin header and you’ll get the fantastic animations seen in the video after the break.

Headpiece Jabbing For Smiles

Happiness_Hat

[Lauren] has created a facial conditioning device dubbed the Happiness Hat. The hat measures a sensor at the wearer’s cheek to determine if the wearer is smiling. When the hat does detects the wearer is not smiling, it activates a servo that prods the wearer. This project is fairly unique in that it provides haptic bio-feedback of what the body is doing, a similar project to the Happillow. While the Happiness Hat seems to work for treating the outward symptoms of unhappiness, this is but an early step towards the droud.

Mini-POV Hat

Viddy yourself this Halloween standing out amongst your droogs with this Mini-POV bowler. We’ll quit with the nadsat so as to avoid a kick to the yarbles, you have our sincerest appy polly loggy for starting in the first place. [cheeto4493] modified a Mini-POV to sit atop the bowler with an extension hanging out toward the brim that houses the lights. A motor, mounted inside the hat spins the entire device. Some counterweight was necessary to keep the whole thing from wobbling too much.

It is worth noting that, in person, the message scrolls slowly by. The refresh rate on the camera causes it to seem to jump around in the video.
