Eclectic junk from the four corners of the ‘Net. And pictures too!
With a small amount of work this pile of parts will turn into a handy air to ground delivery device. As the box is chucked out of the aircraft, a drogue chute pulls open the rotor blades and the entire package auto gyros down at about 40 feet per second (about 28mph). The package can normally hold about 60 lb but can take 100 if you don’t mind an express trip!
I could have used a delivery buy one of these one year at scout camp…
Supplies Away!

This reminds me of my post from a few months ago on a nuclear powered laptop. The BetaBattery would be different as it only creates a small amount of power but can do it for years.
I know that you can buy emergency signs lights that are powered by tritium gas that will last decades. These work by converting the beta radiation into photons via phosphour on the inside of the bulbs.
The Soviets used to use RTGs to power remote radio beacons but those turned out to be quite a problem for some people. As long as the BataBatteries are to be placed in areas that are very hard for someone to work at it with a hammer un-noticed these should pose little risk to the general public. Plus as its power source is a gas, and not a lot of it is in each unit, it would disipate quite quickly in the atmosphere. (like a drop of food colouring in a lake).
The battery’s staying power is tied to the enduring nature of its fuel, tritium, a hydrogen isotope that releases electrons in a process called beta decay. The porous-silicon semiconductors generate electricity by absorbing the electrons, just as a solar cell generates electricity by absorbing energy from incoming photons of light.
New ‘BetaBatteries’ May Provide Power for Decades
Pretty neat, use TV signals to locate an object the same way GPS works, and do it on a $40 chip!
…realized a synchronization feature in digital and analog television signals could be used for other purposes than to lock the vertical hold for older TVs.
The engineers created a radio receiver chip that could zero in on the TV signal and get the synchronization information. Using precision timing, they figure out how far a TV signal travels before it is picked up by a device equipped with Rosum chips. Next, they compare the measurements against other data that they collect with their own listening stations and then finally calculate the device’s position. The Rosum engineers call this process “multilateration,” which is akin to navigational triangulation.
Well, now I have seen a lot of packing styrofoam packing braces before, even used them to built sets but I have never seen an entire monkey temple built out of them.
Hum, thin, cheap, and fast. Look for it when?
Motorola yesterday unveiled a working display prototype using Nano Emissive technology. The technology offers many benefits over existing display types, including quick response times, wide viewing angles and a thickness of just 3.3 millimeters. Even better is news of an estimated cost of just $400 to manufacture a 42-inch NED panel.
