Militarizing your Backyard with Python: Computer Vision and the Squirrel Hordes

Has your garden been ravaged by the marauding squirrel hordes? Has your bird feeder been pillaged? Tired of shaking your fist at the neighbor children? Learn how to use Python to tap into computer vision libraries and build an automated sentry water cannon capable of soaking intruders.

Tech: Pentagon demonstrates “Pain Ray”

Pentagon demonstrates “Pain Ray”

Officially called the ‘Active Denial System’ (ADS), the system uses millimetre wave radio frequency to create a burning sensation in the top 1/64th inch of your skin.

The system could be used to move away crowds or advancing enemies, without doing any permanent damage. After 11,000 field tests, the Air Force Research Laboratory says only two people needed medical attention, one of whom was accidentally exposed to the system operating at 100%.
Last December I outlined this similar system from Ratheon, able to disrupt breathing using a low-frequency speaker system - that device was only at the patent stage at the time.

The ADS demonstrated was mounted on a humvee, and needs 16 hours to warm up before use. In the real world, it is likely to stay switched on all the time to be ready immediately, although that will chew through a lot of gas.

Check out a video of the machine in action here (skip to 1:30 for the action).

Video Distraction: Giant Slingshot Destroys Car

Joerg Sprave has built a new sligshot cannon which he describes as the best rubber-based weapon he’s ever made. The device propels steel balls using 6 full Thera Band Gold stripes per side, which are 72 times stronger than “hunterbands” for conventional slingshots. Check out the video after the break to watch the sligshot pelt beer cans, windows and a car.
