    Still in business!

    I didn’t realize that they were located in El Segundo; that is very close to LA airport (LAX). It only proves that not all California electronics companies are located in Silicon Valley.

    I have a solar powered calculator that even runs off my desk lamp at night. No need to buy or charge batteries!

    Yep – still in business; they make some great products (mainly power MOSFETs)…

    I got one of those electronic boards for Christmas once. Still consider the most fun gift I every got and really wore it out. Mine was from the 1970s and had more circuits.

    It cracks me up that the term “Space Age” is still being use to promote today’s products.

    Yes, and some of the electronics in those days still used tubes! By the mid 1970′s I was putting together Heathkit radios.

    Seems like the “original” 100-in-1 electronics experiment kits that were peddled by Radio Shack for a long time (and now are sold by other companies); I wonder if there is a lineage from the RS lineup to the IR lineup, or if they’re simply similar?

    Oh wow-What memories!

    I didn’t have the IR Solar Cell kit as pictured, but I did have the same exact little solar-cell shown in the lower-right corner.

    My childhood coincided with the most exciting days of the American space program. Dad worked at Grumman (designer and builder of the Lunar Excursion Module- which I actually got to see under construction in an enormous clean room at the main plant in Bethpage, NY).

    These were the years of the Kennedy Challenge, and believe it or not, science, technology and educational excellence were very much in fashion in those days. (funny how that went down the tubes once the cold-war was over, and we no longer had anything to prove to the “Russkies,” but that is another topic for another time.)

    Absolutely everything in those days had a “space” theme- the drawing in the advert was very typical (funny- I never remember seeing any girls in those ads!).

    But anyway- the IR solar cell… I remember it well- The case was a little larger than 1 inch square, made of orange plastic, with a fly-eye clear plastic compound lens. I mail-ordered it from Edmund Scientific in 1971 (before they became Edmund Optics) and how I was totally on pins and needles waiting for the package to arrive! (I was 10 after all).

    It was an important component in several experiments/projects, almost always used as a sensor. For several months, it was hanging in a south-facing bedroom window, and a small transistor circuit I designed would switch on a small transistor radio and wake me up at first-light.

    My favorite project, however, was a photophone I designed and built for my 6th grade science fair. I built a little class-A transistor amplifier that modulated a little #49 pilot lamp bulb (The S-2 filament design had a faster response than the coiled types). It used a carbon button microphone salvaged from an old telephone.

    The detector, of course, was the famous IR photocell, wired directly to the volume control wiper of my transistor radio, so that it could be used as an audio amplifier. I would also use this to “listen” to fluorescent lamps as they started- made a very cool sound.

    Thanks for the great memories!
