    Computer Network Linking Problem

    Hi. I live in a complex with about fory individual houses and about six people per house. We put up a network in the complex. In each house, we placed a 100 Mb switch and connected each computer within the house to the switch. The switches are then connected together to form a large star...

    How can I access Windows files while in linux

    This is something small, so I probably shouldn't reply. I just am for anyone that reads these posts and is left wondering... On my system, I'm able to put the "-t vfat" at the end of the line. In fact I can also type in mount /dev/hda1 -t vfat /mnt/win and this also seems to work well. I...

    which type circuit can get a constant current output

    I think that what you are looking for is a current source or a current mirror. These are active circuits that convey current to a circuit. I would advise looking at any book on transistors. You can build a current mirror BJT's or FETs. These are really low cost circuits. You pretty much...

    Heartbeat Monitor -Help reqd!

    I don't know if you are allowed to, but I think the heart beat corresponds directly with the pulse you detect in the wrist or finger. There may be a slight delay, but at least for a normal person with no arrythmias, I would think this would be the case. If you are struggling to find...

    How can I access Windows files while in linux

    I'm using Slackware 10 and I thought the command should be mount /dev/hda1 /mnt/win -t vfat I tried -o just to see if it works. It doesn't seem to on my system. Another thing: please don't mount an ntfs windows partition with write permission unless you are SURE that your linux supports...

    Why DC shock is more harmful than AC shock?

    Re: DC shock Vs AC shock I don't know if this is fully correct, but I've always thought that current is the thing to be afraid of rather than voltage. Don't get me wrong, high voltage is dangerous, but (at least in South Africa) the earth leakage system is set to 18 mA because 30 mA is thought...

    How to convert the voltage to the resistance with OpAmp?

    I think a quick way would be to use the characteristics of a FET. In the linear region they act like voltage-controlled resistors. In the saturation region they are voltage controlled current sources. The voltage-controlled resistor characteristic of a FET is usually exploited in building...

    Help me realize a divider with AD633

    how ad633 works Hi. I was working on a project the other day and I needed to build a circuit that finds the reciprocal of the input voltage. I tried many designs, but had only limited success. Then I noticed that the AD633 could also divide one voltage by another which was perfect. I built...
