Here is the project deployed in our yard. It’s running on a 6v battery via a 7805 regulator and has so far lasted about 14 hours. Click on the image to see a video.

Eyes Mounted on Frame

Looks like I’m steering away from installing the eyes in furry animals and am mounting it on a wire frame instead. Here are the 14 sets tied to the frame while the Sugru hardens.

Programmer board and first assembly

Here is the development board repurposed as a programmer, and the first assembly. Once I have a few of them I’ll encase them in epoxy and/or Sugru.

Your Furry Friends

Tuesday, October 19th, 2010

Here is this year’s Halloween project. The picture is of an ATTiny45 driving a couple of LEDs via PWM to make them periodically fade up, blink at you for a while and then shut off. It’s running on a 2016 coin cell which gets me about 18 hours of use (not bad). I’m going to make 10 or so of these and put them in some my daughter’s old stuffed animals. Then I’m going to put them all together and have them collectively stare and blink at you. There are two obstacles;
1. Time
2. My wife, who isn’t keen on me mutilating perfectly good stuffed animals. I may have to skulk around the foggy streets and playgrounds of our town in a cape, looking for victims.
