    College, ME, EE, or ?

    College, ME, EE, or ?

    It is not all about the money but it is always nice to make more. I am the kind of person that knows when they don't know something. I know I have some gaps to fill. Because I don't have an engineering degree it's harder to do what I want (not because of knowlege). I guess I am just wondering if...

    College, ME, EE, or ?

    I have decided to revisit my future education plans and I’m looking for opinions on my situation. First let me tell you where I’m at. This may be too much information but you can skip the next paragraph. I’m 30 years old, and a Journeymen and Residential Master Electrician. I started in the...

    SE New technology

    I just spoke with GTAC on another issue but asked about V21 while I was on the line. One of the things he mentioned was that we can chose to model parts the same way we have been (sketches and tree,acts like V20). So no screaming yet.

    Is electric powered transpo the answer?

    A couple of thoughts- What kind of protection do you think would be needed in an accident to protect you from an exploding battery, and what does that protection do to the weight of the car? Eventually the government will want an extra tax tacked onto your power bill for roads and such. Does...

    Contact Resistance Test

    I have to do a contact resistance test on a bus we have installed. The meter I have is a DRM-100 made by Adwel. Does anyone have any advice, tips, tricks, dos or don’ts? Sorry I’m so vague but this is the best I can do with the nature of the customer. Thanks

    So what's this new release all about then?

    I'm not sure if it's v21 but it will soon interface with Siemens PLCs. I believe it's referred to as mechatronics. This comes from my Siemens Automation rep (I used to work with him).

    Produces shortest half-life Nuclear Waste

    There is a vitrification Plant in process at Hanford, Washington. It may have its first Melter finished at the end of summer 08. But the building it goes in will need to be finished before they can even start testing it. The web site is http://www.bechtelvitplant.com/. My hope is that this...

    WinCC

    A friend of mine I used to work with is now the Siemens control rep for our area and he uses a Dell. BUT apparently the Siemens IT guys don't like the way the Automation software plays with others so he has to shutdown and swap hard drives every time he wants to program and then swap back to use...

    480V power wiring: wiring from hot to ground to get 277V - OK?

    By passing your comment “Disregard personnel safety, ground fault protection systems.” Let me make some comments. The fact that your electrician wants to use the ground as a neutral tells me you need a new electrician. Since they are asking you does that mean you get to take responsibility when...

    Centrifuge AC Induction Motor Requireing 30 Starts Per Hour

    I like to use the European style motors for frequent starting and stopping applications. The smaller diameter (compared to the NEMA size) will cut down the motor inertia, a good thing when starting and stopping. SEW-Eurodrive as a reference.

    Vector & Servo Motor

    I just finished working with 3 different manufacturers on two bids for servo applications, and this sound very doable for any of them. Full torque throughout the speed range was a common feature among them all. Also if repeatability in positioning is important you may want to look at putting the...

    Need to make control circuit diagrams for troubleshooting

    I use a software package from eplan, it uses intelligent symbols to keep track of part numbers, wires in cables, cross referance contacts, and will generate reports (parts lists) based of the information you assign the symbols. There are a few programs that are like eplan, and most are set up...
