    im building a little tank thing

    I have two brushed ESCs with their pwm pin connected to a micro controllers output and their 5Vout and GND powering that micro controller, I also have a 3.3v regulator because the micro controller needs both

    the regulators pins accidentally shorted to the USB port

    now the esc doesent output voltage and this little glass cylander gets really hot when I try to turn them on

    is that a fuse that I can replace?
    thats an album of photos I took of the thing

    the thing that gets really hot is labeled "D1" on the circuit board

    No, it's a diode likely being tortured by overcurrent from a shorted component on the board. Not a good sign.
