    Does anyone know the gauss amount of a automotive rotor winding?

    As people know, automotive alternators and gauss meters have been around since before the internet, yet, even though this is true, i can not, i repeat, i cannot find any info on the internet stating the surface gauss of an automotive altetnator rotor. Seems very odd that i cant find that info...

    Guidance Needed: Attempting to Simulate/Generate an Engine Speed Sensor Signal

    Hi everyone! So at work we have several engine simulators and for the ones we currently have engine speed sensors connected to we went about it by using a DC motor spinning a magnetic pulser disc (found here) with the sensor mounted directly in front. Though this works fine, I'd like to start...

    Using 12v brake-light signal as a switch to ground a set of LEDs

    I just want to start by saying I have some knowledge, being an Industrial designer, but I am by no means an expert. I have a set of US taillights, that I have successfully converted to UK regulations (yellow indicators) and I am currently working on a dual function tail/brake light feature. I...
