    And now something weird

    "This is an exciting moment for neutral-atom quantum computing," says Manuel Endres, professor of physics at Caltech. "We can now see a pathway to large error-corrected quantum computers. https://www.pma.caltech.edu/news/caltech-team-sets-record-with-6100-qubit-array

    PCB Component Removal

    You must be patient that is a very large copper pour used for a ground plane so the surrounding area is expected to get hot that is normal.

    PCB Component Removal

    These could be snap in aluminum electrolytic capacitors. these capacitors must be properly discharged to prevent damage to other components on the board. By the way D3 looks smoked. D3 is the component designator for the Diode occupying that footprint written in white on the silk screen. For the...

    Why no more than 4 batteries in any particular string?

    Forgive me, I was addressing the thread starter; given his region in Arizona and his previous questions which I responded to concerning powering electronics off grid. I am not a physics master, but I am hoping to make a contribution by continuing my education at this fine institution where I...

    Diagnosing short to ground issue

    I see solder balls, solder, splatter, short circuit components thank you for the high deaf photo I can no longer help you.

    Diagnosing short to ground issue

    Thank you for the information; if it is a TVS diode it is likely used for electrostatic discharge protection, from high reverse voltage pulses. This is all speculation on my part. I’ll see what I can dig up for you. I need a schematic.

    Diagnosing short to ground issue

    Hello, welcome to electronics lab. I see coax connector gigahertz .What part of your E scooter is the circuit from? If it is a diode the PN Junction can fail, open or short circuit. You measured voltage conduction in forward & reverse bias. If it was a reverse voltage or current protection...
