    Closed: Good cheap DDR4 RAM memory site

    Hi guys,

    I found this site which offers a lot of things from "AliExpress", but they filter the sellers for us and only offer us the high quality. If you need something that they don't have, send...

    Closed: Re: SPI protocol with SD card

    Can you post a circuit? If your module has SPI, you connect it to the MCU and then from the MCU to an mp3 player chip, you might be able to skip the MCU.

    I think you want details about proprietary technology. The site I gave you should have a datasheet. Otherwise you need to contact intel about this information.

  8. Closed: Re: Canoe: Driver - Reception overrun : Messages are lost

    Your system configuration is not the problem. I am using "CANoe" too, this happens when you leave "CANoe" without a filter and it keeps sending/receiving. To fix it just clear the messages and send...

    This is a hard topic, I suggest you test with care!
  10. Closed: Re: Resistors for high soldering temperature

    Another option is a cooling system, use the box of the PCB as a cooling system, make it metal and add an external cooler, or add an internal fan if its enough and does not interfere with the work of...
  11. Closed: Re: Resistors for high soldering temperature

    Your first problem is that you want it to be "SMD". Use through hole it provides better cooling. Get a 2W resistor and check its ratings on "components supplier". If it can not be used, get a "5W"...

    Closed: Re: Measuring Voltages using MCU

    A good question, I like it. Lets start with this, do you know the difference between "AC" and "DC" current? Do you have 2 separate grounds, do you have an optocoupler between the VAC and MCU ADC? Do...

    Closed: Re: audio input to amplifier.

    The 2 wires right before the speaker(1W) need to be connected to an audio jack(stereo or mono) and after that you can connect them to an amplifier or which ever system is powering the big speaker(200...

    This should have been the file on why the voltage increases more without grounding. I will look a bit more if this is not it.

  16. Closed: Re: How often do surges happen on the mains?

    If you want to reduce the spikes, there are a few ways, thats why I asked for your system type. Adding additional grounding poles is the easiest way, it will stabilize your voltage, make sure they...
  17. Closed: Re: How often do surges happen on the mains?

    Even if the voltage is with 20 volts higher, that is enough to damage your devices. They are built for 250VAC maximum. Also you are wrong, the current rises for a short time, but that is more than...
  18. Closed: Re: How often do surges happen on the mains?

    Thats a trick question, it depends on more than 1 thing. To begin with, how close are you to the main transformer for the city?

    2. How...
