Make a Soda Bottle Bike Exhaust

Make a Soda Bottle Bike Exhaust

My son has this totally awesome “exhaust” pipe on his bike that I covet. It’s really a resonator for the classic baseball-card-in-the-spokes trick. It makes a terrific racket, and gets people to move out of the way without necessitating a honk on your horn. I decided to build my own, using a recycled beverage bottle. Armed with a Dremel Rotary Tool, a bottle of energy drink, and a depleted gift card, I set out to make my own soda bottle bike exhaust.

How-To: Make a buckle from nails

I found this cool light blacksmithing video from YouTuber SgtViktor at How to History, an online clearinghouse of traditional handwork tutorials. To be fair, the bucklemaker in question uses all kind of modern power tools and abrasives, but the site is nonetheless a great resource. Other personal faves include How to Build a Coracle, How to Set a Copper Rivet, and How to Make Handmade Nails. [Thanks, Matt Fedorko!]

How-To: Quick ropecraft laptop shoulder sling

It’s probably not much good against the rain, but this handy bit of urban fieldcraft from YouTuber sumitsumit would be hard to beat for showing off your DIY-fu at the local hackerspace, coffeeshop, or school. Pretty much guaranteed to impress that attractive gentleman or lady in your engineering class. It takes about 20′ of rope, includes an adjustable shoulder-strap, and–I suspect–could probably be tied or untied in ten seconds or less with practice. I don’t want to spoil sumitsumit’s reveal, so I didn’t include a screen-cap, but you can scan forward to 4:20 to see the finished product. [via Boing Boing]
