Re: SMD or through hole
It sounds like you have more sophisticated toys than I do.  I was able to generate a provisional patent with wire ties and wire recently.  It can still be done low budget with objects that are just laying around but alas, some of the stuff was bored from my son's RC car parts bin.  It could justify hoarding but then again, how much is too much?

Re: Printed PCB
Interesting stuff.  I'll have to try it out.

Printed PCB
A new alternative is the conductive ink printer like the Voltera. I acknowledge that it is pricey for a home/hobby set up, but not so bad if you can treat it as a business acquisition. Watch for my blog the Voltera V-One on embedded.com in May.

SMD or through hole
Nice post, Scott,

In my case the selection between SMD or TH for prototyping is driven by several things. For slow circuits with just a few components I often used the breadboard, when noise was a concern or for circuits destined to last more than a few minutes I then used a fragment from a protoboard. In some cases a breakout board comes very handy for small SMD packages.

But in most my current prototypes I go directly to building the PCB in our workshop. The whole process takes in many cases just a couple of hours, including the PCD design. I use one CNC controlled mill (modified BF20L Vario + Mach3). For generating the G-Code from the gerbers I use flatCAM and auto-leveller. It is not difficult to make double sided PCBs this way with track widths down to 0.2mm and isolation of 0.25mm using LPKF 0.2-to-0.5mm bits.

I modifed flatCAM (it is open-source, written in Python) for optimizing the generated output G-Code. With the original code you often want to modify the ouput g-code to make it safer and faster.

With all of the mergers, acquisitions, and spinoffs going on in the world, I’ve been thinking about writing an article on this subject for several years.
I have NDA’s to protect my client’s interests however at times they can be limiting to a point where they require adjustment. That’s why I read every NDA in full several times.
Recently Radio Shack closed many of its store fronts. This is a major blow for those of us who need quick solutions when building circuits.
