Stumbled across an article describing the ‘ADALINE’ #perceptron emulator, an analogue circuit, made entirely by a resistor and potentiometer network.
Being from the early 60’s, there’s not much information to be found these days on the device, but I managed to build it pretty much the way it was - at least I think so
It’s quite fun to train and test with different patterns - units like these are the vintage foundation of modern neural networks, AI and language models.
