Using the Smart Phone Scrap Bin

A project video: what can you do with an old smart phone? In this case my old Samsung Galaxy S2. Well, it has a bunch of sensors including "gyroscopes" that are actually accelerometers. So I turned it into a cheap (saw blade) inclinometer. Doing this with the Galaxy was fairly easy because the phone has a flat back; at least, it's flat in all the places that matter (so why the video still takes 12 minutes is a bit of a mystery). I did try using an even older phone - an HTC - but that had a rounded back. However, if yours has a curved back and you're interested in what I tried, leave a comment and I'll do a supplementary on the HTC. SAFETY NOTE: if you have cross-cut (or any other kind of) table saw sled, not only should you paint the blade areas red, and have a blade box or a double trailing fence, but you should also have push handles in a safe place, and consider adding something painful so you can't push on a red area!
