With all our modern devices using surface mount technology , it’s still worth pointing out that vacuum tubes did more than just the tasks of amplification and switching.
Dieter Wächter shows us this with his extensive write-up on his Beam Deflection Decade Counter Tube Clock build. He gives us a great explanation on how this display tube works, pin-outs and detailed design photos.
Something magical about a display tubes green glow. 😀
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.
