Q: The problem with pcb manufacturers is it only becomes cost effective if you do multiple boards of the same type. Small batches etching at home is more cost effective.
A: By the time you get all the materials, create a good 1:1 negative or positive film, etch the boards, and drill them, let alone deal with through holes, a commercial board service proves more economical and without the problems of safe and legal chemical disposal. I have etched boards with a commercial UV-sensitive film and the results were OK, but not great. Maybe the process has gotten simpler and the photo-sensitive films better, but even for small hobby projects it's a pain.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
