    Best example of overbudgeted jobs

    Figure that, worldwide, on the order of 10^8 or 10^9 persons, businesses, or households, pay for Internet connections, an ISP, or both, at an average of approximately $20-40 each, per month. That makes that a total of between $10^10 and $10^12 per year. How much was the original budget for...

    Assembly of ferrite Chokes (to reduce RF)

    IRstuff: I tried, but all the ones I found with enough impedance where either bigger on the outside, smaller on the inside, or both. We have very limited space in the assembly. biff44: We only sent the product for EMC compliance testing twice; it passed the second time. The problem is now...

    Assembly of ferrite Chokes (to reduce RF)

    Multiple persons tried to locate the source and fix the problem and the source. None were able to do so. You may be right about using a capacitor to slow the edges, but I am only on this project until the end of this week, and it would take longer than that to evalaute your idea. Also, I have...

    Assembly of ferrite Chokes (to reduce RF)

    1. The board manufacturer wants too much money to include the chokes in the production units. Also, not all the boards we buy from the manufacturer need the chokes, and for reasons that are not important to this discussion, we are not going to get some boards from the manufacturer with them and...

    Long Lasting Adhesive/Sealant

    About 5000 years ago, the ancient Egyptians sealed a pyramid so well that the air inside was studied by modern scientists to see what air was like at that time. This chamber and a bubble trapped under the polar ice cap were the oldest two known samples of air isolated from the rest of the...

    Analyzing Parking Garage for large crowd of people

    Your "first thought was that vehicles weigh more than people" is seriously flawed. The persons that can fit in a given space weigh more than the vehicles that can fit in that space, even if each person individually weighs less than a car. A car is as wide as approximately four persons...

    Assembly of ferrite Chokes (to reduce RF)

    You have some good ideas, but I am only on this project until the end of this week, and most of them would take longer than that to implement. Also, I have no authorization to pay for more emissions tests, so the solution needs to be an implementation of something that we have already tested...

    Assembly of ferrite Chokes (to reduce RF)

    Two are right-angle blade connectors which (because of the right angle) are more difficult to fit through an opening than straight blade connectors. We considered changing the board but decided against it. I've seen the test results, including graphs of dB versus frequency, not just the...

    What does "Venditori de oleum-vipera non vigere excordis populi" mean?

    I meant my post about Leno's chin, not the post by Gunnar Englund.

    What does "Venditori de oleum-vipera non vigere excordis populi" mean?

    In case anyone could not tell, that was a joke.

    What does "Venditori de oleum-vipera non vigere excordis populi" mean?

    Maybe Leno's famous chin is really a device that emits heavy metals to give everyone near him brain damage.

    deciding wether one or two pump is needed

    Regarding 2 x 100% pumps versus 3 x 50%: With 3 x 50%, you are more likely to have two simulatenously out of service and therefore fail to achieve a total of 100% from what is in service. With 2 x 50%, you are more likely to have everything simulataneously out of service and therefore have 0%...

    Patterns

    Even if mirroring features does not work, mirroring the entire part may work. Depending on which release you have, this is either Feature > Mirror Geom (which is the entire part; to mirror individual features was part of Feature > Copy) or "Select the Part name in the Model Tree > Edit > Mirror".

    2-part adhesive systems - meter/mix applications

    The cordless tool that I was describing mixes at a specific ratio and delivers a shot of adjustable size, but it dispenses from cartridges or sausages, not directly from bulk containers. To make it work with bulk containers, you would need to pump the components from the bulk containers to the...

    Assembly of ferrite Chokes (to reduce RF)

    We are trying to reduce RF emissions to comply with a legal requirement. I think this originate in the board and are radiated by the wires going to the motor and the wires going to the battery. The interference is not affecting the board to our knowledge. To unsolder and resolder, we would...

    What does "Venditori de oleum-vipera non vigere excordis populi" mean?

    I think the the majority of persons who Leno questions are of normal or above normal intellect, but he only puts the ones who seem ignorant on the show, and that many persons pretend to be stupid in order to get on TV.

    Canadian Electrical Code

    1. Why not just replace the wires? 2. Make sure you have adequately dealt with the issue of different voltages and frequencies (transformers can correct the voltage but not the frequency). 3. The EU has been 25 countries, not 15, since before the post that lists 15 countries.

    Getting CE marking on new motor

    To CE mark something with a motor, you usually also have to demonstrate compliance with the EMC Directive, usually by testing to (other) standards, not the safety standards that you use for the Machinery and Low Voltage Directives.
