55-year-old Peijia Wu, from Shandong province, allegedly took three months to build his DIY wooden bike. It features no metal parts whatsoever – joints are fixed with small wooden bungs and a rod-crank system has replaced where the chain would normally be.

Ingenious! It's like a stair master and a bike rolled into one and it's probably less likely to fall apart than other wooden bike models. [Chine Informations via Shanghaiist]

Because the instructions are in a foreign language, we can't exactly tell you step-by-step how this basic ring flash is made—but looking at the pictures, it seems like with just an old plastic cup, bunt cake tupperware, duct tape and aluminum foil, you'll have your own simple, homemade ring flash in no time.

Heck took apart the kick pedal that came with GH4's drum set and used the piezoelectric switch in it, McGuyvered it into a little chamber with a diaphragm and added a tube that uses air to hit the switch. Voila, instant breath-controlled pedal!

This Do-It-Yourself Safety Alarm Clock will only shut off after you've unlocked it with a key. When you go to bed, simply set your alarm and lock it in by turning the key. In order for it to have the maximum effect, take the key out of the lock after you've turned out the lights and then toss it into the dark abyss that is your room. In the morning when your alarm sounds, you'll be forced to crawl out of bed and hunt for the key before you can unlock your clock and shut it up.

Knowing me, I'd probably end up making duplicates of the key and hide it under my pillow, but hopefully you won't be a remarkably industrious lazy ass and do the same. Head on over to Instructables to see how this Safety Alarm Clock is made. [Instructables via Make Blog Thanks Seung!]

The pumpkin is based around an Arduino board, with a few LED lights and a super loud truck horn, which definitely makes it the most annoying—or loudest, or even most obnoxious—pumpkin ever, but definitely not the scariest. Make sure you're wearing earplugs and a diaper as you head over to MakeZine to see step-by-step instructions on how its made. [MakeZine]

The hack requires a little plumbing know how and some circuitry work, which makes it slightly harder than your normal DIY project. To help you and your pets out, Tsruzik has put together some kits for order. Prices range from $10 to $125.

The end product works a lot like those sinks that automatically turn on when you waive your hands under them—except instead of detecting hands, it detects cats. Tsruzik has even thrown in an optional “people detector” so that the faucet won't run every time a person walks by. Check out the video to see some cute kittie drinking action:

The project, from Instructables user Ricardoaraujo, uses a normal toy lightsaber hilt, some AA batteries, a rubber hose and a couple of LEDs to build a weapon you'd be proud to kick Jedi ass with. Now all you need to do is knock back a couple too many Guinnesses and find some Obi Wan Kenobi-worshipping dork to smack around. Death by pretend lightsaber it shall be!

If you are interested in building one of these yourself, the designer is in the process of developing a simpler, cheaper version complete with detailed information and schematics. Until then, you can hit him up for some info on the project in the following link [N1VG via Hack a Day via Make]
