Halloween Props: Spooky eyes light up the bushes

This is just one example of several pairs of spooky eyes which light up [Vato Supreme's] bushes this Halloween. The quick and inexpensive build process make it a perfect diy decoration.

Each eye is made up of a ping-pong ball and an LED. But that alone won’t be very spook as the entire ball will glow rather brightly. So he spiced things up a bit by masking off the shape of a pupil and spraying the balls black. The vertical slit seen in white above will glow red like a demon in the night.

The LEDs are driven by an ATtiny85 running the Arduino bootloader. [Vato] found there was plenty of space two write code which fades the eyes in and out using PWM. This happens at random intervals for each of the four pairs he is driving.

We’ve seen a similar project that used oversized LEDs as the eyes. But we really like the idea of using a diffuser like this one. See it in action after the break.

[Vigo's] stare follows you wherever you go

To decorate the office for Halloween [Eric] decided to make [Vigo the Carpathian] stare at passersby. We hope that readers recognize this image, but for those younger hackers who don’t, this painting of [Vigo] played an important part in the classic film Ghostbusters II.

In the movie, his eyes appeared to be following anyone looking at the painting. [Eric] grabbed a Kinect and used Processing to recreate the effect in real life. The image is displayed on an LCD screen. A bit of work with Photoshop allowed him to cut out the eyes from the image, then create sprites which are moved by the Processing sketch. It’s reading data from the Kinect (so it knows where to ‘look’) which you can see perched on the top of the cubicle wall. The illusion is delightful, see for yourself in the clip after the break. We’ve already watched it a half-dozen times, and it looks like it was a real hit with the guests at the open house.

Can you believe they threw this together in just one day?

Animated LED eyes for Halloween

[Matt Daughtrey] sent us this sweet little project he’s doing for Halloween. He’s building some animated LED eyes. He says that the whole thing is 3 individual LMDriver platforms, another project he’s working on. There isn’t any info available about that, but he does expand a little. He states that each display module uses an Atmega169 with some heavy multiplexing.  The eyes really don’t look that impressive sitting on the bench, but watch the video to see how cool they really are.

We noticed that the back of the boards appear to have http://www.embeddedether.net on them.  Unfortunately that site seems to have been grabbed by a domain squatter.
