      The Engineering Mindset Hi, i’m a fan of your videos, I’ve been watching them to get through school and they’ve really helped me understand things so thank u, but I was wondering whether u could do an explanation on the differences between conventional current and electron flow? Like are they the same thing cause like u said current is the flow of electrons in a circuit and and they flow from the negative terminal but conventional current flows from the positive terminal then soo??

    Is there a kind of thermal sensor just turning on or off following if we get below a temperature or above a temperature ?
    I struggle to find this kind of components.
    I dont want in my application what is the temperature between A and B. But just to know if the temperature is below A or above B.

    • @caffeinatedinsanity2324

    I have a problem I have tried to solve for years. Controlled from a computer, control at least 32 (off/on) switches, isolated, with a possibility of an acknowledge line back to the computer. What circuit will do it?

      Top of my head I'd say use a raspberry pi to control an IC chip and piggy back more off that to give you 32 on/off points. Can then use relays off those to control larger circuits

    indeed. 3 ways the heat is propagated: conduction like this video. convection and radiation.

    In you graph at 9:29 it looks like a thermocouple has a negative resistance -> Free energy machine coming? :P
