This iteration of Electronic Design: Now and Then was inspired when I was reading "Using Magnetic Cores in Computers" from our archives. This article was originally published in Electronic Design ...

Many Hackaday readers will be familiar with the term “core memory”, likely thanks to its close association with the Apollo Guidance Computer. But knowing that the technology existed at one point and ...

Do you know core memory? Our prehistoric predecessors would store data in the magnetic fields of ferrite rings, reading out the ones and zeroes by setting the magnetic field and detecting if a small ...

Inductors are deceptively simple. However, a closer look reveals underlying complexity. How else can you explain the many types of core materials, types of windings, sizes, geometries and wide range ...
