Multitouch Table by GreenerBusiness

  Seems like these multitouch tables are showing up everywhere. This one is done with a cute video that brightens up the build process. Best of all these old projectors are being thrown out in favor of the smaller, higher resolution and more portable versions. Thanks Ravi "The image processing software analyzes inferred light from the web camera and treats any light detected as a separate input source. Then this

Mechanical Digital Clock

  Mike Saunby got his hands on one of the most interesting old clocks I have ever seen. It does time and date which isn’t any great feat by todays standards but have a look at the complex electro-mechanical goodness that makes it tick. The big question here is who made the thing, there are no markings on the clock to give us any clues. Anyone know? There are some

Lightspeed Passive Attenuator using Silonex NSL-32SR2 Optocouplers

  I remember when taking electronics in college it was mentioned that you could order standard transistors, or you could order matched transistor pairs for high end audio use. A pair of transistors that were matched would work in perfect unison since even devices out of the same batch will have some slight variations. Have a look at the image below for an example of testing a ton of devices

Pole Climbing Robot

  The RiSE Version 3  robot looks freaky, it appears to be some type of small animal scampering up the pole. The University of Pennsylvania has some cool tech coming out of its Kod*lab. "Unlike RiSE V1 and RiSE V2, this newer version adopted a quadrupedal configuration, and was designed by Boston Dynamics, with input from the RiSE Project consortium. RiSE V3 uses brushless DC motors that increase power density.

Snoop on Pager Data Project Completion

  On Monday we featured the first part of Pager Data Snooping experiment. The video above demonstrates the completion of the experiment where the data is successfully retrieved from the device, conditioned and fed into a serial port, some special software allows a Windows computer to display all the messages that are being transmitted to pager clients.

Cell Phone USB Ultrasound

  The power of a modern cell phone is changing how many things are done today. For example I recently heard that the once CPU taxing program Myst was now available for the iPhone. I think I had to upgrade my video card to play that game years ago. Thanks to a Microsoft grant some software was developed to display data from a USB Ultrasound device. This technology allows for
