I haven’t been to a gym in a long time… From what I recall, there was more ‘roid rage.

It looks like my mom has perfected her apple pie. The crust was pretty delicious.

Paperkit.net lets you print out different types of grids. I only wish is that they had a 12/16/24 column grid as well as a grid for the iphone/ipad. Hmm, might be an opportunity for someone to create this. ^_^

Okay, this is another must-see movie coming soon. Need to talk to our team to see who can go.

These are two gigantic solid state musical Tesla Coils. A Tesla Coil is a special type of transformer invented by Nikola Tesla that is able to generating extremely large voltages using a phenomenon known as electrical resonance. Each coil in this video is capable of generating a 13 foot spark. This equates to about 500,000 volts of electricity.

The primary drive system for the coils consists of high power semiconductors arranged into an H-Bridge switching configuration. During a spark event, the coil is pulsed on for a few hundred millionths of a second. During this short time, thousands of amps circulate within the primary tank circuit and the energy is coupled into the secondary resonator through magnetism.

So what appears to be a continuous burst of sparks is actually a specific number of sparks generated per second. By modulating the number of sparks that emit from the coil each second, different tones can be produced by the coils.
