  The Libelium Team have created a Geiger Counter (radiation sensor), and shipped the first batch to Japan's Tokyo Hackergroup and other people helping in the relief effort. The Arduino sensor board can sense radiation all the way up to cancer inducing levels. In the video Vaseline Glass (Uranium glass) was charged with ultraviolet light, which allows for a few minutes of weak radioactivity. Complete schematics and source code can be downloaded from their site, or you can buy one of the kit ...
  E. Lelic has given out a battery tester circuit, controlled by a PIC 16F88, that can charge, discharge, measure internal resistance, and capacity of Li ON, Li Po, Ni Cd, Ni Mh, and regular cell batteries.   Capacity is measures through the logging of how much mAhs the battery has accepted. Charging can be started at stopped at will, and switched to discharging if need be. Over-charging protection is built in. Lelic states that we should not trust what the batteries are rated at, and ...
No one needs a 4G mobile phone, but it seems as if everybody wants one, if for no other reason than to receive such bandwidth-intensive services as streaming video on demand. So, with consumers clamoring for multimedia-on-the-go and other mobile data traffic on the rise, network operators are looking towards 4G as a more efficient means by which to meet customer expectations. That, in turn, translates into a sharp rise in network complexity and a greater emphasis on innovative test solutions to ...
