Is it just me or are the two sides in this argument not seeing on the
same level? It seems Jonathan is looking at the problem through a
"mass production" viewpoint, which would require a somewhat good
design of all components in the device, i.e., circuit boards, casings,
components, etc. Everyone else seems to be thinking through the
DIY/hobby design viewpoint, i.e., simple-to-build. The former will be
more elegant in terms of circuitry, software, and even the enclosure.
If you're a hobbyist (any level of skills), then it won't really
matter if it's a kludge build, as long as the basic components do
their job and you can get "up n' running" quickly.
