Jim Timely, Jameco's ace inventory specialist, wants a highly secure method for the escort vehicle to send information to Jameco's cargo truck. The truck is following behind the escort as the two vehicles roll along the highway. The communication method must be ultra-secure and not employ visible antennas or other clues of the technology. Cell phones, CB radios, WiFi and other traditional radio methods are unacceptable due to their security vulnerability.
How can they safely communicate without a radio?
We hear about temperature everyday: Twenty below in Fargo. Bake at 375 degrees. You have a slight fever, honey, so you better stay home from school. How do we actually know the temperature? There are conventional thermometers that use mercury. And there are modern thermometers that measure change in resistance within a circuit.

Power lines run straight through the Kenyan village of Elburgon, but only the wealthy can afford the electricity. Everyone else uses firewood and kerosene lanterns at night. Led by a Rice University student bringing little more than a process and some encouragement, the Kenyan locals created their own design and today the wind turbine powers a light and a few computers at the local school every night. The Rice University team has quickly expanded and needs a little bit of help from us to help teach self sufficiency to those who are hungriest for the knowledge.

As soon as the box was opened, everyone wanted it to perform instantly. "Make a bunny!" cried one. "The Statue of David" cried another. "Make a gun," said yet another. The pressure was on to print the first object and bypass the instructions. If only we had it to do over again.

Club Jameco Hot New KitsAnimated LED Eyes They're creepy! They're funny! The luminous green eyes blink and scan the room in random patterns. If the optional PIR sensor is installed, they pierce ahead when someone enters the room. Add additional sets to see an entire "wall of eyes" move in unison.

Mounted on a door, this device senses a knocking sound and knocks back the same way. It's a great prank or a spooky effect. The simple circuit uses Arduino, an electret microphone module and a servo motor.
