    [SOLVED]Closed: Re: trace width to current handling

    I think you implied this in your question, but just to re-iterate there are three things you need to consider when figuring out the current handling capacity of a trace/track.

    1) Obviously, the...

    Closed: FatFs and Windows 10

    The generic FatFs used to be compatible with older versions of Windows. Is there any way to use FatFs with Windows 10? I suspect not, but I would really appreciate it if anyone knows how.

    Thanks...

    Closed: Re: SD Card not showing 4 GB

    Use any partition manager to destroy all the partitions and then format with FAT32. BTW, you need to remember that SD Cards use the K, M, and G conventions, not the IEEE Ki, Mi and Gi. So a 4GB card...
  4. Re: Need advice on what programming language to learn.

    I have been programming for more than 25 years on C, C++, C#, Basic, Visual Basic, Java, Python, FORTRAN, and COBOL. For what it is worth, a few pieces of advice:

    1) IMHO, once you learn any...

    [SOLVED]Closed: Re: ULN2803 as Input Protection

    My bad. I obviously meant ESD protection devices. I am familiar with TVS diodes, but they tend to be expensive, even in bulk. The only ones I know to be remotely affordable are the SMAJ5.0A series....

  7. Closed: Re: Selection of ICs, Transistors, Power Supply for Big 7-Seg (say 6 inch) for MCU

    I did a similar project recently, except I used MOSFETs to both, sink and source, current. Have a look at the AO3400A (N Channel MOSFET, Min Vgs(th) = 1.05V, Max Id = 4.7A) and the AO3401A (P Channel...

    [SOLVED]Closed: ULN2803 as Input Protection

    Hello everyone!

    The ULN2803 is commonly used in MCU projects to drive high-voltage or high-current loads. But I have been thinking about using the ULN2803 as a high voltage input protection device...
  9. [SOLVED]Closed: Disconnected Diode in MC34063A Circuit Heating Up

    Hi,

    I made a step-down power supply using the MC34063A switching regulator. The configuration was straight out of the datasheet (schematic attached). However, I neglected to connect the anode of a...
