Halloween props: Techy Jack-o-lanterns

Halloween is this weekend. If you still have some time and parts available, you might be looking to spice up your Jack-o-lantern.  We’ve found a few projects that we thought might be nice to share. None of them would merit a post on their own, so we thought we would just round them up and share them all at once. They all appear to be powered by the Arduino, which we know will bring some comments. Just to clear up some questions, they don’t pay us to advertise Arduinos. People just do a lot of projects with them.

First, the silly string shooting Jack-o-lantern which you can see above. He’s using a single servo hooked to an Arduino and a motion sensor.  When it detects motion, it lets out a short squirt of silly string. You can download the code from the project page. We might suggest you arrange this in a manner to avoid spraying directly into some kids eyes.

Check out the next two after the break.

[Ben] told us about his POV globe yesterday. We took a look and saw just one photo and the code with no real explanation of his project.

His build is well executed and he found some creative ways around the common problems in these projects. We take a closer look after the break. [Read more...]
