Next stop, SMT

The little hardware project, mentioned previously, continues to chug along. A prototype is now happily blinking LEDs on a veroboard:

Now it's time to use a real technology, so the thing could be used onboard a car or airplane. Since the heart of the design is a chip in LGA-14 package, we are looking at soldering a surface-mounted element with 0.35 mm pitch.

I reached to members of a local hackerspace for advice, and they suggested to forget what people post to the Internet about wave-soldering in a oven. Instead, buy a cheap 10x microscope, fine tip for my iron, and some flux-solder paste, then do it all by hand. As Yoda said, there is only do and do not, there is no try.
