I have no circuit design experience and have a manufacturing/mechanical background, so this question may sound stupid. Is it common practice(or done at all) to design a board so that two components are shorted(on purpose)? Or is this most definitely a manufacturing error?
The components on the...
I have some rubber in a system where I noticed a yellow color on the rubber inside and also on place surrounding it. I noticed this after a long period of time(it was not there when the system was first made). My research indicates this may be sulfur. The rubber I have will be used in an...

I am machining a tube of acrylic. I am noticing that afterwords when putting the acrylic into contact with solvents(Alcohol in particular), is cracking at a very rapid rate. However when I place the stock material in contact with this same solvent it does not crack. What can I vary within the...
I am looking for an adjusable shaft to measure the perpendicularity of a hole. The problem is that the hole can varry in diameter by quite a bit(.015).
The same concept is used in a bore mic but I do not need to actually measure the hole.
I need plastic tubing 2.375(OD)x2.125(ID), does anyone have anywhere where I can find this?
I need the following materials Polycarbonate, PVC, HDPE. Is this size available or will I need my own extrusion?
I can find this size with acrylic however not with the above.
