Question: #electronics #toroidal
What if I accidentally double the input voltage for a 160VA toroidal transformer being used to charge a battery via a bridge rectifier? Dual primaries can be wired parallel for 115V input, or series for 230V.

(it's only a backup for when the more sophisticated charger isn't available, and I'm the only user.)

I mean obviously it's going to overload and get very hot very quickly, but is there a rule of thumb for the effects of saturation? Fry in seconds? :-)

I mean, couldn’t the #orgchart be hierarchic, or matrix, or star-shaped? (I realize this is pretty low on the list of issues in this news release, but still, I’ve been thinking about the “ring” issue since my MBA over a decade ago.) https://www.npr.org/2024/01/03/1222130537/jeffrey-epstein-court-records-reveal-men-clinton-prince-andrew

I've been hoping to see these toroidal propellers on PC fans! I can't wait to try this for myself.

Spy Drone Propeller Makes For A Quiet PC

MIT recently announced its research on toroidal propellers to create quieter drones. That got [Major Hardware] thinking about noisy PC fans. The obvious solution was to adapt the toroidal shape for…
