HOW TO make Advanced Spud Guns
As the title says, advanced spud guns. The site includes plans for spud guns from an experienced builder. The highlight of the site, which the link points to, is a huge spud gun based on the revolver design (i.e. old west 6 shooter, magnum, etc), and plans are included. Link. Thanks Eric!

Cute project – Recently many kind of robot contests have being opened and some interesting reports of the challenge are found on the web. The Line Following is a kind of the robot contests to vie running speed on the line. I build a tiny line following robot which can run on the desk, moving the key board aside will do. It is for only a personal toy reduced its size less than one fifth compared to typical line following robots, not in formura.
Nice hack for duping slides- I started this because I have about 2000 35mm slides and nearly that many color negatives I’d like to convert to digital images, and many of them are 30 years old or more and starting to deteriorate. My first attempt involved purchasing a slide scanner from the-store-that-must-not-be-named, but it took like 3 to 4 minutes to prescan and then scan to file, and then it usually botched the exposure or the color balance. I realized that I didn’t want to spend the rest of my life scanning slides in this manner, so I started thinking about other solutions…[

Nice HOW TO, would work for other little creatures too – I know there are many feeding systems available in the pet shop but I don’t want them to have access to the specialised food the whole day. Exposing them to an unlimited supply of grains, corn, … would stop them from eating my kitchen waste (and that’s why we bought them in the first place). [
