    How Do You Confirm a Suspected Short on a PCB?

    I would briefly check the voltage regulators, diodes, capacitors and output transistors for a short. Then I would remove the suspect component and check it again out of circuit. Also check the PCB to see if the short has gone. Sometimes a higher current will blow the short open circuit. A...

    speed controller

    27.145 MHz is channel 4 or YELLOW for RC cars, boats etc. It’s now old technology. But to answer your question, it’s definitely possible and reasonably cheap to do so. You will have to disassemble the train. This will most likely involve replacing all the electronics in the train for a digital...

    Recommended ways to program Uno board

    You don’t generate its code, you write it. C or C++. But there are 10s of thousands already written on sites like Arduino or github. YouTube is a great source for Arduino programming. Even chatgpt will attempt writing your code. Obviously, someone else’s code will need to be changed to exactly...

    Will an over‑discharged "dead" battery be woken up by NFC wireless charging?

    I think the battery chemistry would be damaged if depleted below a certain threshold. Reviving a fully depleted/discharged cell may work for a limited time but the damage is done.

    1. Have you tried cleaning the lens?. 2. It’s a risk that might pay off.

    Burned traces repair help needed

    You can use bare wire. The traces and connections are not insulated. Be mindful of bending the wire where the original track was. Enamelled copper wire is better though. Some techs would do a nice job of repairing the board using eyelets in the holes. These get pressed in and make great connections.

    Burned traces repair help needed

    That depends. If it’s a half hour strip down, half hour repair and half hour reassembly, that’s probably not bad. But for a few jumper wires and a SIL preamp and just the board in front of the tech, that’s a lot. Ask if you can do all the donkey work and he does the soldering.

    Burned traces repair help needed

    Such a shame as it would have been an easy fix providing nothing else was fried. Look at the component side and reference designators for each component. Then look at the component layout in the service manual that @danadak linked to. It will be easy to see which connections are required.

    How good is Spain for Embedded System Engineers?

    I think your question is straightforward. If your español esta muy bien, join a Spanish forum that deals with your enquiry and ask them directly.
