    Do any of those programs allow an edit on the files?

    The PREVUE won't open the .gdo files. I have uploaded the files in question.http://files.engineering.com/getfile.aspx?folder=0e1a361d-a687-4a3a-bd40-b99549598288&file=Rev3.2_EB1_update_gerber.zip

    Hello, does anyone know of a (Free) program that can view gerber files or .gdo files? I am looking at project example files from Texas Instruments and they have the extensions .gdo in a folder named gerber. I would really like to modify their board to fit my needs exactly rather than starting...

    FEA of Magnetic fields

    We are trying to visualize the "interference" of 3 parrallel conductors magnetic fields. Could anyone please suggest a free source to model or calculate the field patterns?

    Wireless "wire"

    what is "stack"? I am looking at the TI msp430rf-2500. I just don't know how "good" of a signal I would get from that circuitry. They say it has a 10bit ADC and up to 200kBps data rate. How do you get a "feel" for how accurate the sampling/ADC/DAC would be?

    Wireless "wire"

    Basically, I want a set of ICs that I could provide power and an AC signal to and "replace" a length of wire. They would only "talk" to each other, allowing for multiple sets of ICs in the same area. The semiconductor level is prefered(cost), I have found some "boxed" sets for $150+, but I am...

    Wireless "wire"

    Hi, I was wondering if anyone had a "low cost" solution in creating a system to read a 0-5V AC signal and wirelessly transmit then "reproduce" the signal. I need "high" accuracy, say +- 0.5%

    Metering CT

    The unit would be used on outdoor switchgear to get "load" values. Not for revenue metering.

    Metering CT

    My application is metering.

    Metering CT

    Hi, I am looking for help locating an "off the shelf" outdoor rated CT. I am fairly flexible on the output and ratings. I would like to find "anything" low cost (<$150/unit) that could monitor load current 0-2000A @ 38kV with better than 5% accuracy.
