Here's a blimp with its own ideas of flight. Nick Wagner and
his fellow classmates at Colorado
designed their infraLED Zeppelin to maneuver in two modes. The first is remote
control mode where a transmitter sends directional commands (forward, back,
left and right) to the blimp and the blimp responds accordingly. The second
mode lets the blimp chart its own course to a predetermined destination. In the
autonomous mode, the blimp flies to an infrared (IR) beacon. IR transmitters on
the blimp receive a signal from the beacon, and the transmitter facing the beacon
receives the most pulses. The blimp then goes in that direction.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
