…most common method of tattooing in modern times is the electric tattoo machine, which inserts ink into the skin via a group of needles that are soldered onto a bar, which is attached to an oscillating unit. The unit rapidly and repeatedly drives the needles in and out of the skin, usually 80 to 150 times a second
Tight, now doctors can give patients a recording of their heartbeating sounds saved to an ipod!
Capturing heart and lung sounds is the most critical aspect of stethoscope design. Acquire the sound accurately, and anything is possible. The patented Electromagnetic Diaphragm (EmD) is unique to a Thinklabs stethoscope, and is the key to audio quality.
Having captured an accurate signal, electronic signal transmission right to the eartips ensure

So we made the MP3 player and it works freakin’ great! The sound quality was as good as an off-the-shelf MP3s. We plan to hack it using a CuTOUCH CT1720 and make some cool touchscreen menus for it.
Here’s some pictures of how it will fit in the touchscreen enclosure: (It fit perfectly!)
The only hurdle we face now is changing the

Whoa, check this video out. It’s crazy what ice and cold can do…
On the fateful snowy day in our video, things worked a little differently. When these people pressed the brakes, the heat generated by the tire-on-ice friction created a thin film of water over the frozen surface. The coefficient of friction for tires on ice with a thin film of water between them is pretty much zip, resulting in—you guessed it—auto Ice Capades. It took almost no braking force for the cars to skid and, once skidding, they continued in a
Here’s a cool DIY on how to make an invisible book shelf that floats in the air.
Here’s a tight little project that can cost very little to make if you need to make your own GPS data logging system for your next hiking or outdoor adventure!
This project focused on creating a simple serial data logger for the Delorme Tripmate (also known as the GPSTripmate). The Tripmate is an older GPS receiver that can be purchased on eBay for < $20. I happen to hav
