RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Lego Robot for Solving a 3x3x3 Rubik's Cube Videos for Engineers
Watch a Nokia N95 smartphone drive this LEGO Speedcubing robot (big sport in the robotics nerd world). Constructed
entirely from LEGO parts, it includes a vision system for ascertaining the cube's state while solving a 3x3x3
Rubik's cube from any start position in under 20 seconds, including the initial image capture. Thanks to a
passionate, dedicated user base, LEGO has come a long way since introducing the blocks in 1949. They now carry a
complete line of robotics devices, including processors, motors, and vision devices.
Here is a nifty bit
of trivia for you:
LEGO is an combining of the
two Danish words leg and godt, meaning play well.
OK, so who can't solve a 3x3x3 Rubik's Cube? Watch Brain Guy solve a 7x7x7 in 6 minutes
and 19 second!
