    How many of you have experienced this? (link to video)

    As an engineer, I have found myself in this kind of situation in many meetings. http://www.youtube.com/watch?v=BKorP55Aqvg Most of you have experienced similar situations because you too are an 'Expert'. However, if you don't understand this video, or cannot fathom the humor, then, maybe you...

    Just How Smarter Engineers Are Than Everyone Else

    Someone just sent me this link and I thought I would share it here. Engineers as a whole are very modest; we focus on our jobs of designing things and solving problems, and never give much thought as to how we might compare with others on mental ability...

    Need help with relay data

    The company I work for has older products they support on a repair basis - products inherited from other businesses. I need a datasheet for a dip relay - Sigma 191TE1C1-24L. Sigma has been out-of-business for years. Under most circumstances, I would get another 24 volt dip relay from another...

    Thermal Image Camera - What features to look for?

    I am looking into getting a hand-held thermal imaging camera for use in design verification and prototype evaluation of circuit board power assemblies. There are so many of these cameras types out there for maintenance use in checking circuit breakers/wiring, building insulation checking, and...

    Electrical Engineering being hit hard by the economic downturn

    Every engineering discipline is being affected by the present economic conditions. But I was somewhat surprised by the following article posted, of all things, on a website that more centric on scientific articles and issues. http://www.physorg.com/news166208581.html The information originates...

    Help with Common Mode Noise Calculations

    Common mode noise arises in switching supplies from the capacitance of the power devices to the heatsink (surface area, insulator thickness and dielectric constant) and the switching speed and waveform of the power devices. An engineer I work with has seen a book or article that works one...

    Intrinsically Safe Radios and Phones

    Some of the discussion in thread248-169911 is making me ask a question I've always wondered about. I design low power circuits that are tested to intrinsic safety standards. This is not a problem when the circuit requires only a few milliamps at 5 Volts or less. However, I see advertisements...

    Reversing collector and emitter on a PNP

    I am working with a product problem. This industrial product was designed around 1970, and consist of a mixture of discrete transistors, and LM741/LM308 opamps. In other words, the engineers who designed it are long gone, and the circuit approach is not-at-all what would be done today. But I...

    How do you measure the impedance of a balanced transmission line?

    The regular RF measurement equipment allows for easy measurement of the impedance of 50 or 75 Ohm unbalanced transmission line. But if you have a symmetrical 2-conductor structure, how do you determine the impedance (without a formula)? I have a "probe" structure of two parallel flat...
