    How do I make an Equipment ground

    I am building the Elenco AM/FM radio kit. And for a static power test it is telling me to connect my equipment ground to circuit ground test point 15 while the circuit is being powered by a 9volt battery. . I’m just pretty confused on what it means by “equipment ground” and what I can do to...

    Choosing proper grounds for sensitive 5V electronics (vehicle project)

    Noob alert! I'm tinkering on my garage project, standard vehicle stuff - 12V lead acid battery, 3-phase stator, reg/rec. I would like to put few additions to its circuit. Being a rookie, I'm not sure how to approach this correctly in terms of providing safe 5V for these microcontrollers. I've...

    Grounding problem is coming between boost converter and mosfet driver

    I am designing a boost converter which is rated on 100 watts, 12 volts to 24 volts, switching frequency is 20 khz, in open-loop conditions. when I give the input power supply to the circuit as 12 volts, my driver (HCPL 4506 Mosfet Driver) will take VCC as 24 volts due to My microcontroller can...
