I felt like that when I learned about magamps last year... they were hiding in plain sight for my entire life

- evilspacemonkey 6y agoDude, I am probably as hardcore as electrical engineers come (define your metric, I will (probably) beat it :-) )... I learnt about magamps from your post today. Thanks
- mikewarot 6y agoI repaired a lot of Westinghouse Industrial Control Modules that were built in 1964 with early transistor technology as a rule, The most interesting was a magnetic amplifier module, it had 4 windings as inputs, each thus DC isolated from all of the others, AND it worked all the way down to DC... which I didn't expect. The drive frequency was about 10 Khz. --- In the 1950s, transistors weren't yet reliable enough for computing, so they invented a solid state computer in the 1950s that ran at 1Mhz, had few transistors, and a few big tubes driving the clocking, it used magnetic amplifiers for logic gates. https://en.wikipedia.org/wiki/UNIVAC_Solid_State https://en.wikipedia.org/wiki/UNIVAC_Solid_State
- ggeorgovassilis 6y agoThat is seriously awesome. Touched by history.
