Salvaging ferrite cores with Hot Air

| 2020/02/06

Method: Salvaging ferrite cores Why The world is full of electronics being unceremoniously discarded. Said electronics contains power supplies. Said power supplies contain a number of magnetics, namely transformers and chokes with ferrite cores, of all sorts of sizes and shapes (well, usually E or EI, but anyway). A computer power supply will have several.…
