My buddy who is a mechanical engineer says that IE's are "Imaginary" Engineers because any engineer can do what they do. He says that he knows Civil and Mechanical Engineers who do Industrial Engineers work but none the other way around because they are not as good. So he gives me crap all the time and tells me not to do it. I want somebody to tell me the reality of it. What jobs are there out there?

I'm told that paint finishes on SS do not last. Anodizing is too expensive for my application and I don't want to get into chromated steels or aluminum.

Need to start search on which materials (metallic alloys, but not necessarily restricted to metallic alloys) combine the property of good electrical but low thermal conductivity. For example, Stainless steel is better than Copper in this respect.

I'm designing a fixture to test a 12vdc & 24vdc motor at different times. The fixture has a dual output (12&24) DC power supply.

The operator of the fixture needs to change the voltage between 12 & 24 vdc. The motor leads are connected to a pair of spring loaded binding post. The voltage at the posts needs to change.

Is a rotary switch the answer? Any recommendations?

Thanks

Mark

I suppose this is a material science question - does anyone know if Q345E-Z25 is equivalent to the ASTM spec S355J2G3-Z25. Alternatively, can anyone suggest where to find an English languange version of the Q345E-Z25 spec so I can compare the two myself?

Thanks!

I have a project with senses whether my garage door is open or close. However, I am having a problem with the sensors. I am using magnetic reed switches which are generally known to be very reliable. Does the fact that I am attaching it to the garage door which is a completely aluminum effect it?
1- I notice that switch works (I can hear the clicking ) once it is of the garage
2- but once I install it- it works for maybe two cycles
3- after I remove it- it doesn't work for some time and then starts working again...

I want to build a light like the one below because I don't want pay $35 for a pre-made one. I know it can be done because I own a night light that is just a blue LED. I figured $35 for what amounts to a cluster LED's, a resister, a compositor, and a base is a bit excessive when you figure they're built in bulk.

When I searched on Google all I could find was plans for battery powered lights.
