Macrofab Engineering Podcast

Stephen and Parker have been testing the main opamp for the OPA541. Stephen wrote a blog post detailing the opamp tests with simulation and real world testing. GitHub link to the repository for the SSPS. Giant 200W 8Ohm resistor. Liquid Cold Plate Heat Sinks for cooling the opamps in the SSPS. Isolators for the opamps made out of Aluminum Oxide. Part no. 4180. They make Beryllium Oxide Ceramic isolators but not in the right size. Antek transformers is the company that makes the Doughnut (Toroidal) Transformers Parker and Stephen are looking at. Really neat Super Capacitor Flashflight. A 30F 3V cap would weigh 5.685x10^-12 kg more fully charged vs discharged. It would take roughly 176 billion of these super caps to have a charge weight gain of 1 kg. Carbon film capacitors sounds almost as cool as carbon nano tubes. If they can replace bypass caps it would make compact board layouts easier.
