    Component symbol... CRT's PCB

    I found this info: "Viewsonic 1769gs-2 monitor FCC gss17005 has no hi-voltage.  Fbt, hot, etc seem ok.  Replaced lm-2931 & 74hc00 on the aux. board.  All ps voltages ok" "If the HV builds and collapses, and everything else is ok, then you may have a shorted transistor on the CRT socket...

    Component symbol... CRT's PCB

    If you tell us the make and model maybe someone got a schematic or a manual for your monitor! Also a picture of the PCB with the remains might help!

    0-30 Vdc Stabilized Power Supply

    Hi subumann, That looks just great! I have to ask; do you plan the layout for the board on paper or do you have some software to do the work? Good work!  ;)

    Pump protection circuit

    Hi Steve, Yes, I believe you should use an amplifier and a lower value for the resistor. You might also get away with using a smaller input voltage for the A/D (fewer bits) and still be able to sense the current with enough accuracy.

    Advice on AC motor speed reduction?

    Hi Guys, From what I have seen; a single phase motor with a starting cap on the side is actually a 3-phase motor able to run on a single phase by means of this cap!? In that case it should be possible to run the motor from a three-phase frequency converter if the cap is removed and the jumpers...
