***WARNING*** if you attempt any project that uses explosive materials please exercise extreme caution. These videos show you how to make a smoke grenade (second video) and how to make a pull ring that will allow it to be ignited just like a grenade.
Is your desktop quad core computer a bit slow for your liking? If SGI develops this concept into an actual product you may be able to add some horsepower to your computing needs. "Engineers at Silicon Graphics research labs developed the system to show how consumer electronics technologies and emerging marketplace trends might someday be applied to overcome the limits of today’s high-throughput clusters. The Silicon Graphics Molecule concept
Carl Erickson from Phenostream has built a very small yet very smart stepper motor. Many of them can be controlled via a daisy chained serial connection which could make it simple to interface with complex projects. This car project is a cool example of the possibilities. "The OpenStepper Module (OSM) is comprised of a GSM_01 and the OpenStepper circuit board. OSM firmware is based on Mike Thompson’s popular OpenServo
Here is an interesting talk with Mitch Altman who is the creator of the TV B Gone. It is nice to see that he is genuinely interested in sharing his electronic passion with others.

A Gyroscope, Accelerometer and Magnetometer are used to allow a small electronic device that is worn in a boot to keep track of your movements and therefore your actual location.
If you get a sore back from bad posture habits or repetitive stress situations from work this Strain Sensors technology could help you in the near future. The sensors remind me of the glove keyboard sensors we have seen before. If this technology advances as fast as everything else is we will soon have these microscopic sensors woven directly into the fabric of a shirt and the outputs will
