Finally! Figured out how to print nicely and cut in a straight line

Not-so-shameless plug (hey, you’ve been asking!): These are freshly posted in my etsy, if you’re interested.

I can’t believe this is the last day! I’ll post one more thing tonight (this post is for yesterday).
Thing-a-day really got me goin! I’m feeling so… useful haha

Seriously though, is there a year round community for this? I want to keep going. I guess I could start my own blog, but having a community to interact with would be way better! Does anyone know? I cant find any info about it on the thing-a-day site.

So, the thing I kept trying to make kept breaking every chance it got. Finally, it somehow turned into this. Basically, I whipped something together using the slide mechanism from inside a printer, an Arduino, a junky photocell controlled H-bridge left behind by one of my least promising students this summer and the relay controlled extension cord I used in the penguin.

In short, as the thing moves back forth, it hits a switch which turns a lamp on or off which in turn changes the direction its moving in. There’s two seperate circuits at work. Yup… that’s pretty much it.
