    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.

    Arduino Nano built in RGB LEDs won't turn off

    What Nano have you got? The 33BLE is active low, meaning they’re on. High turns the LED off.

    tek 2712 identification of a destroyed component

    Can you see the reference designator for that particular component?. Your photo is not sharp enough to see. But as mentioned above, more than likely a battery or electrolytic capacitor. Edit: you see no markings for it.

    110/120V inline ammeter.

    Thanks for the ideas. I opted for a cheap easy solution. I purchased a meter (photo below) and will house it a plastic box with 110 and 240v plugs along with 16A and 32A outlets. Hopefully it’ll be somewhat accurate:). It’s supposedly 50VAC - 500VAC, 0A - 120A. It will never see anything above 30A.

    110/120V inline ammeter.

    Yes, I did start doing that. But then I needed a 16A to 32A adapter and vice versa. I was hoping for an all in one inline ammeter similar to the photo I found on the WWW.:)

    110/120V inline ammeter.

    Hi forum friends, It’s not always easy or possible to open site tools (110V) to measure current by opening the circuit and putting the meter in series. I am looking for a plug in device inline with the tool and transformer. 240V versions are readily available everywhere. The 110V transformers...

    Changing USB Powered Security Cameras to AC 120

    Yes of course. The easiest solution is to use a 120VAC to 5VDC step down power supply. The cameras should have a label with power specifications or at least in the instruction manual. Get a power supply with more current (A) than actually required to allow for headroom and running cooler.

    Double up on the battery. If it lasted ‘10 times’, it should last 20 times.

    RF booster or repeater

    Example on the theory. Your query seems to have changed somewhat. Now you’re asking about transmitting RF. And not causing interference. This is not advisable. Use the appropriate repeater/booster that’s readily available and doesn’t require a license.
