30-Year-Old Rechargeable Flashlight with Gallium Arsenide LED & Simple Circuit Reverse-Engineered
Pretty novel old design – with some slick-looking nickel-cadmium cells that are still in incredibly good shape given their age.
A bit of electronic treasure from the past. I bought this unique little rechargeable flashlight from a long gone (and much missed) shop in Glasgow called RME. The RME stood for Radio, Mechanical and Electrical, and it was a surplus and salvage store based in Howard Street in Glasgow, Scotland.
What made this little flashlight appealing was that it was rechargeable directly from the 240V mains supply with a standard figure-8 style mains connector. I was very intrigued by how they had managed to fit a charging circuit inside such a small light. keep in mind that this was from the 1980’s so it seemed a remarkable electronic feat.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
