Red Plating Vacuum Tubes to Destruction!

In this episode we have a bit of a laugh and try to destroy some vacuum tubes. Red plating is when there’s a problem in the circuit and too much current is trying to force its way through the tube. The electrons start to smash into the plate and it gets hot, ultimately glowing red. This ca

C. De Lellis - Center manifolds and regularity of area-minimizing currents (Part 1)

A celebrated theorem of Almgren shows that every integer rectifiable current which minimizes (locally) the area is a smooth submanifold except for a singular set of codimension at most 2. Almgren’s theorem is sharp in codimension higher than 1, because holomorphic subvarieties of Cn are ar

HP Switching Power Supply Repair Part 1: How it works

Here is another full debug of a not-so-vintage switching power supply from hell. Highly frustrating, yet highly instructive. It comes from a valuable HP 85645A tracker, well worth trying hard to repair it. In this first episode, we reverse engineer it, explain how a switcher works, and s
