I like dead-bug prototyping, and do plenty of it. But I don't like how difficult it can sometimes be to replace components, and I HATE slicing copper clad by hand. So to make my life easier, and considering how little a 10x10cm board from China costs, I made this dead-bug breadboard. Figured I'd share it in case someone else finds it useful.
http://imgur.com/a/sXVlx The board measures 99.7 mm x 99.7 mm. The top layer has two independent power rails and ample grounding. The prototyping areas are sliced into .250" x .175" pads with 25 mil spacing. The bottom layer is a mostly-solid ground plane.
There main prototyping area is composed of four ground-encircled quadrants of 20 pads each. Four smaller auxiliary areas near the edges can be used for off-board connections, voltage regulation, and constructing inexpensive wirewound scope probe jacks.
For RF work, there are two dedicated footprints that accept standard vertical or right-angle BNC connectors, although most right-angle connector bodies will overhang past the board edge by about 1/3rd.
If you want one, the attached zip file can be submitted directly to a board house. Add your own fab notes if required.
