Day Five: Under $100 Open-Source Arduino Moving Projection Instructions

Today, we're venturing into the world of open-sourced prototyping. While a lot of what we do at Li Sashay is commercial, a good bit of it is also whimsical and fun. This is one example.
Jeff dropped by one evening asking me what I knew about sewing. One of those down the rabbit hole questions that is always promising. A few days and I had his prototype in my studio. Jeff is busy designing an open-source Arduino driven moving projector screen.
This is a really brilliant design and incredibly simple. I won't speak to the electronics (You can check out his blog for exact details and open source code), but you create a basic projection screen from blackout-fabric ($30) at any Jo-Anns. Use a basic straight curtain rod curtain design. At the top you attach straps at 8-12 inch ($2 for a yard) intervals that wrap around a hollow pole, I've seen plastic hollow tubing used ($10 Lowes). You then attach a controller to the entire curtain and for under $100 depending on where you source your parts. If you scrounge the board and motor, you can do this for closer to $50.
Voila, a moving projection screen that rolls up and down at your command. Now all it needs to do is Tweet.

Well, that's all for today folks. Have a great day. Check in tomorrow for more free ideas.
