Things you can make from an old DVD drive #1 - Crawlerbot Inchworm

I had to replace the DVD drive in my old PC today and that gave me the idea for anotherof projects. I will see how many projects I can generate from the components in the old DVD drive. This is the first project and I make one of my old favourites, a crawler bot or inchworm which uses the tray mechanism to reach forward and pull itself along\r
If you find this video has a high pitched whine that makes it unpleasant to view I have a second version with a low pass filter here \r
\r
If you have a question it is probably worth reading this video description first because the answer may already be here. To help you find my videos I made two search guides or or checkout my playlists page \r
