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...

How does anyone even think of this stuff? This video demonstrating how to turn your
smartphone into a holographic projector was posted by
Mrwhosetheboss on August 1, 2015 and has over 10 million views
already - and it's no wonder. He doesn't mention on the video what inspired the idea. A clear plastic CD jewel case cover it used to make
the projection surface and specially created videos that project onto the four faces are used to create the holographic effect.
The concept reminds of a little multi-faceted mirrored device that used to be sold which sat in the middle of a record player and turned
flip-book type still images printed on the album into a simple video. My cousin had one. A little research just now turned up the Red Raven Magic Mirror(videos on website) from Morgan Development
Laboratories. The records ran at 78 rpm, which was probably necessary in order to avoid the flicker that would likely be noticeable
at 45 rpm or 33-1/3 rpm. As with most things these days, you can buy a Red Rave Magic Wheel and records on
