Hey, I've always been fascinated by how computers work. And I've wanted to build a 'computer' using rudimental technology ever since. I watched Linus's video with Destin and decided it was about time I built my own memory and logic. So I went and bought myself some Ferrite Toroid Magnets. I was wondering if y'all could help me out with all the specifics? How do I measure the threshold voltage required to flip the magnetization of the toroid? Should I trace it's Hysteresis Curve, if so how? Does the gauge of the copper wire matter? What waveform should I input? Does the
