Memphis-based Ardent Recording Studios, recording home to ZZ Top, George Thorogood, REM, and countless others was formed by three tenth graders in the 1960s. One of the three dropped out of the recording business and went on to form another company. Who was this person and what was the company he founded?

Fred Smith left Ardent went to college and turned his passion for aviation into a fly-by-night operation named Federal Express.

Student Builds Robotics System for Oregon Zoo Elephants

Robotics System for Oregon Zoo ElephantsRohan Jhunjhunwala, a mechanical engineering leader on the Catlin Gabel School’s robotics team, was approached to build a robotics system for exercising and entertaining elephants at the Oregon Zoo.

The robotics will consist of three parts: an apple launcher, motion sensors and capacitive sensors built into a four-key piano. The system will be used to feed, exercise, and entertain the elephants.

With funding and materials secured, Jhunjhunwala is currently coding and building intensively over the summer and hopes to have things operational in prototype form in the fall. The final product will be completed in time for his school’s science fair in March.

Tech Lowdown
Easily add local or remote I/O to industrial computers

Easily add local or remote I/O to industrial computersAdding local or remote I/O to Relio R1000 industrial computers is easy with SeaI/O data acquisition modules. SeaI/O expansion modules communicate with Relio R1000 computers via RS-485 (Modbus RTU) and allow mixing and matching up to 246 modules to create the most efficient I/O configuration for your application. Expansion modules can be located together with the Relio R1000, or a network of expansion modules can be daisy chained throughout your facility using inexpensive CAT5 cabling connecting the RJ45 pass-through connectors included on each SeaI/O device. SeaI/O expansion modules are available in a variety of configurations providing optically isolated inputs, relay outputs, TTL interfaces to industry-standard solid-state relay racks, A/D, and D/A.
