    I am trying to use existing spare c

    I am trying to use existing spare circuitry on a board to supply the controlling inputs to an SSR. It seems what I have most readily available are a comparator circuit and some optoisolators. The relay is the Crydom CMX60D10. Anyone have any suggestions? Thanks!

    Current Sensing circuit issue

    I have recently designed a servo loop circuit in which current is sensed across a 0.1 ohm resistor and fed back into the input. The difference across the resistor is fed into an opamp with a gain of 10. The output of this opamp with the current artwork is approximately 30% higher than expected...

    Voltage Level Shifting

    I am trying to figure out the best way, with the least number of components to translate a voltage from -12V-5V to 0V-5V. I am using a comparator to compare negative voltages and the only negative voltage I have available to me on my board is -12V, so I have to use this voltage to supply the...

    Power Distribution Job

    I am thinking of applying for a job at a local power distribution plant. Can anyone who has been in the field for a while give me some pointers on things that I should be knowledgeable about in the interview? It would be a great help!

    Transistorised Relay

    Can anyone tell me if there is something more up-to-date to replace transistorised relays, or if not, a company that manufactures them?

    windows apps on windows CE

    I wrote some software in vb.net and vb6 and was wondering if there was anyway to get this software onto a windows CE machine without recoding. Does any emulator or other method exist that you know about that will allow me to do this? Thank you for any help that you can give me.

    Phase Rotation Detector

    Can anyone fill me in on how a phase rotation detector works? I need to alter an existing design, but I'd like to understand how they works before attempting to do that. Any help would be great!

    Overspeeding baldor motor drive

    I am wondering if anyone knows how to overspeed a baldor motor using a baldor inverter control. It is currently running at max 1700rpm and i need it to run at 2400rpm. I am sure it can be done because I have contacted baldor and they said it is possible. Now I just need to figure out how...
