“Hey look, I just built a radio in 2 minutes!” (Nov, 1968)

“Hey look, I just built a radio in 2 minutes!”

With new Lectron transistorized magnetic blocks, it’s easy to put a solid-state radio together Then take apart and build an electronic organ in minutes, or a burglar alarm, automatic night light, rain indicator, Morse code transmitter, intercom and many more that really work. Simply match symbols on Lectron see-thru blocks with circuit diagrams in 68-page manual No wiring. No tools. No experience needed to have hours of fun while you learn electronics. Completely safe. Lectron sets begin under twelve dollars wherever fine toys are sold.

Lectron makes electronics child’s play

    Magnetic connections are a cute idea. I’ve never seen these; “Snap Circuits” are similar:

    I had these in the late 60s early 70s! They were very cool and worked surprisingly well. Time to visit my mom’s basement where all my cool toys ended up after I left for college.

    eBay to the rescue…

    Well, that certainly didn’t keep kids busy for long.

    I’m still waiting for the “Mr. Fusion” kit.

    Lectron are still being made, and the number of blocks have been expanded quite a bit (solar panels, etc.). The trick is, their website is in German. Not inexpensive, either — the starter set is priced at EUR175. No internally moving parts, though, and I remember them from the 1970s as being fairly well built, so they should last a long time.
