I have an interest in electronics from the 1960’s and 1970’s. One rather unique product of that time is a hands-on “building block” approach to putting circuits together, somewhat like the much more recent Legos RCX controller and associated attachments. This article describes the introduction of the Raytheon Lectron series of electronic block kits.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I actually remember having one of those sets. I suppose it would be valuable today; but in true hacker fashion, once I graduated to breadboards and PCBs I cannibalized the electronic parts for other projects…
