DIYer Steve Hoefer has been hard at work making every 6 year old's dream come true: A device that unlocks your door whenever someone seeking entrance taps out the secret knock.
His device, which fits easily over the inside of your doorknob and lock, counts the time between successive knocks and can be reprogrammed to whatever knock-pattern you see fit. If the wrong series of knocks is tapped out, the device simply ignores it and waits for the appropriate pattern to allow entrance.



In the late 19th and early 20th century, enigmatic photographer T. Enami (1859-1929) captured a number of 3D stereoviews depicting life in Meiji-period Japan.
Gizmodo:Impressive DIY flame thrower... I recommend the other hand spit out ice... or at least be rigged up to a fire extinguisher. Heheh.
Pyro was never my favorite of the X-Men, but that doesn't mean I'm not excited about this DIY project allowing me to mimic his powers. It's called Prometheus, and it's by far one of the best wrist-mounted flamethrowers I've seen.
