[Davide] sent us this fun LED matrix mask he built using an ATMega8 and 74LS595N shift registers. Each of the eyes is an 8×8 LED matrix, and the mouth is made from two 8x8s. [Davide] used a ULN2803A Darlington transistor array to drive the matrices.
When the user steps behind the mask, an IR sensor detects that a face is within range and activates the facial features. The code randomly runs the eye and mouth patterns. If the user starts speaking, a microphone element detects his voice and a separate speaking mouth pattern is executed.
The mask body and stand are découpaged with pages from Dylan Dog comics. [Davide] says he built the mask years ago, but decided to submit it to the 2013 Inverart Art Fair in Milan. As you can probably imagine, the mask has been a big hit with the kids so far. Stick around to see [Davide]’s Santa-fied demonstration after the jump. [Davide] didn’t give us any details on that sweet hat, unfortunately.
If you require a better degree of protection or more LEDs, check out this LED helmet.
WTF is it Halloween? I thought it was Christmas? I need to lay off the holiday spirits over here.
It’s really Halloween. It’s just that all this early Christmas marketing crap’s got us all thinking it’s Christmas already.
Does not Dec 25 = Oct 31?
Happy October 31st!
25 DEC == 31 OCT
Neat idea. Now I want all of my projects to have little faces that respond to user input.
