This is something which is usually not covered by the functionality of common EDA-Tools like EAGLE. Here's why: This is done by milling after processing all other production steps of the PCB. It can't be done by just omitting something in the prepregs used, as they can contain only drills for vias. And the latter is only done when buried vias are needed. ...

I have drawn many footprints/landpatterns i different ECAD tools. How the recommended footprint dimensions are specified differs a lot between manufactures. Some have dimensions that can be used right away, others you have to calculate the dimensions you need to draw the footprint. My guess would be, that some of the guys putting on the dimensions in the ...

Back branches create loops. And any module that contains a loop becomes subject to the Halting Problem — to wit, you cannot write a program that can in all cases determine whether the module will exit the loop. When you're writing software for real-time systems that have hard deadlines, you want to be able to prove that the deadlines are always met. ...

Develop your requirements. This will be everything from the end functionality to how it's powered, to how every single component should function within the system. This gives you a set of parameters for your design as well as a rough idea of the needed modules. This is because you will be breaking down your idea into modules with which each can be designed ...

Designing something like this will take a while, and it's too much to really do through a site like this, but I can at least tell you how I would set about it: Break the task into chunks, and do each in turn, and Start with the important bits - in this case, it's going to be all about the interface. There's a whole lot of mechanical stuff to sort out too, ...

I think that what you are saying is to "add gain" but not "invert" the signal. Your added amplifier is an "inverting" amplifier. You are "going into" the - input. So just use a "non-inverting" amplifier, "going into" the + input. Not sure of your experience level .... do you know how to do that? You can search for "non-inverting op amp amplifier" on ...

That all looks fine at a basic level but you must bear in mind that a short on any one of the loads will pull a current only limited by the supply and the cable resistance. Figure 1. A selection of PTC fuses from LittleFuse. You should probably protect each socket with a resettable fuse. See LittleFuse PolyFuse Selection Guide for a well written ...
