About RF Cafe

    Kirt Blattenberger,


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...

These images have been chosen for their uniqueness. Subject matter ranges from historic events, to really cool phenomena in science and engineering, to relevant place, to ingenious contraptions, to interesting products (which now has its own dedicated Featured Product category).

When LEGO blocks were first introduced in their current form in Denmark in the late1940s, founder Godfred Kirk Christiansen could not have imagined how wildly popular his "toy" would become with sculptors. That generations of kids would while away hours at a time building original and predesigned structures per printed instructions were his realized dream, Godfred (may I call him Godfred?) would be in awe over how his creation has been applied from professional and amateur artists. The June 2012 issue of Scientific American has an article titled "Fusion's Missing Pieces" on the current state of nuclear fusion, and with it is a photo of a cut-away view of a tokomak made entirely of LEGOs by Sachiko Akinaga (click thumbnail above for more pics). Do a Google search on "lego art" and be amazed at what is out there. "lego robotics" turns up hundreds of often sophisticated microprocessor-controlled machines. Try it on just about any subject, be it engineering, science, chemistry, mathematics, industry, aerospace, automobiles, architecture, or electronics and be amazed at the skill of people. You might find something that will make a good cover photo for your next PowerPoint presentation (be sure to give attribution to the creator). LEGO is a contraction conceived of by Christiansen from the Danish phrase "leg godt," meaning "play well."
