Dekatron as Internet speed indicator


https://www.electronics-lab.com/dekatron-as-internet-speed-indicator/

spritesmods.com has build a interner speed indicator based on a Dekatron tube, the result is great. As most electronic engineers and hobbyists do, I have a great respect for the earlier ways of controlling electrons, before it was found out that silicon could be used to miniaturize everything a thousandfold. It is amazing that things […]
