I have been creating circuits for mumble years, using wirewrap, IDC and standard PCB technology with plate-thru hole (PTH) components. I’ve recently been “forced” to use surface mount devices (SMD), and was concerned that it would be too difficult for an amateur using only equipment available at home.
I was wrong; it was easy.
On the off-chance it inspires others, here’s what I’ve used, what worked and what didn’t. The tl;dr version is DesignSparkPCB, DirtyPCBs, OSH Stencils, 179C SnPb paste, magnifying visor, *8 lenses, reflow sand in skillet, soldering iron.

Summary: it does work and isn’t too painful. Naturally I’m evolving methods and techniques as my skill improves.
This outlines how I placed solder paste, placed components, saw small components, soldered and reworked small PCBs. I didn’t want to be constrained by the time it takes to apply solder paste, position components, and reflow in the HackSpace oven, so I looked for ways I could do the whole process at home.

See this new page for details of the theory, the performance and manufacturing.
All too often signal integrity aberrations are visible in digital signals displayed on an oscilloscope. Fortunately signal fidelity can be significantly improved by a simple homebrew 3D-printed accessory that can be retrofitted to any standard scope probe.
