    I want know multicomp Website

    No. Or not that I'm aware of. Element14.com would be the closest.

    I want know multicomp Website

    Farnell aka Element14 own the name. They apparently use it to brand cheap stuff from whatever source they can find. So there's no single manufacturer and no distributor other than Element14

    Need Help to find suitable magnetic sensor

    Hall effect is sensitive to the strength as well as the direction of the magnetic field. It is thus not surprising that linear detectors are bipolar. A precision rectifier could possibly solve your problem, but you need an OP-AMP and several other assorted components. Maybe you could use 2...

    Microcontroller ClockCycle speed thing question

    No there are 1 million clock cycles per MHz. 1 Hz is literally 1 cycle per second, so 1MHz is a million per second. Hopefully my previous post answers some of the other confusing details.

    Microcontroller ClockCycle speed thing question

    If the frequency is f, and the number of clock cycles required is c, then you might imagine that the number of instructions or second is f/c. However, instructions frequently require several processing steps, let's say the are 4 steps each taking at least 1 clock cycle. Whilst each instruction...

    You're right. You may need to contact them and ask.

    Noob Soldering Problem - Which Wire To Use?

    I had to admit it, but for quick one-off things, it where I need something a little better than a breadboard, I use matrix board and wire wrap wire. Making a 1cm link with two stripped ends can be really fiddly. I think I spend more time stripping wire than anything else. I'd love to find a...

    Solar panel , grid tie inverter mismatch ...

    You need the specs for the inverter. Some will simply limit the power they draw, others will melt.

    Decoupling capacitors

    In theory, theory is no different to practice. In practice it is. KVL assumes that connections to nodes have zero resistance or inductance. In practice there are stray resistances, inductance and capacitances which have a real effect. If the IC in question demands a sudden high current, the...

    how to fix LCD problem

    Debugging? Which is all I can suggest in the absence of any real information. What's the LCD? Interface? How have you tested it? What has changed between your testing and now? Etc...

    SPST tact switch and rotary encoder with push switch

    But you have a part number. Try mouser, RS, etc. and see if they have it (or one similar) with a smaller order qty.

    LED project, heat dissipation

    You might also consider using aluminum cored circuit board.

    Testing capacitors

    See page 4-14 of this for the conceptual diagram. It doesn't include the switch that is required for practical purposes, and if you follow the instructions for discharge, it is clear that the diode is between the switch and the electrometer (unless you use a low voltage zener diode). In any...

    Yeah I noticed that after I read beyond the first part. :-(

    does 8051 support for RTOS ?

    You realise that RTOS is a class of thing, not a thing, right? Did you check the link I have you?

    does 8051 support for RTOS ?

    The main feature it should have is a version of an RTOS ported to it. Which real-time OS do you have in mind? And WHY do you need a RTOS? edit: and have you looked at http://www.freertos.org/
