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...

RF Cafe Video for Engineers - World's First Cellphone Spotted in Charlie Chaplain Movie?For the last few months, a clip from the Charlie Chaplain movie "'The Circus," filmed in 1928, has been somewhat viral within the techie world because it includes a short segment where there appears to be a strolling woman talking on a cellphone. Of course, that cannot be what she is doing, can it? It sure does appear like she's talking on a phone. Only a very few explanations are possible. 1: She is a space alien amongst the human population. 2: She is merely an early adopter of oblivion-like behavior. 3: (and this is the most likely) She is part of a vast government conspiracy that has had advanced technology for decades and unintentionally walked into a movie shoot, thereby exposing the devious scheme. I will be filing a Freedom of Information Act request later today.

 

The scene is 20 seconds into the film.
