Did you know resisters come in concrete? I Didn’t until now. Working on a circuit that will allow me to measure the power output of my Sterling Engine.

My first attempt sucked pretty hard. I feel like I significantly improved by the forth wire. But now I’m left wondering, how the hell do I connect all four of these wires to a single pin?

Ignore that it’s a snake nest right now.

All the modules are finally talking to each other! debounce, logic, display, pulse, everything’s alive and working!

Next step: figure out how to wire it together on a perfboard.

When you sketch a circuit with solder and tinned wire, you are already building it !

A scan of the underside of a cheap perforated prototyping circuit board - "protoboard" or "perfboard" - showing its pattern of pads and holes, along with the brand/model name "Radio Shaek 2". :wink: This is a typical crappy generic Chinese board, made from laminated paper. The copper pads are very thin and the glue holding them to the board isn't great, so they lift off the board very easily when soldering, or especially desoldering. The holes aren't very well centered in the pads. There's no soldermask, so it's easy to get accidental solder bridges. The board is browish tan, and has an 18 x 24 grid of holes, so 432 holes total. There are 2 continuous busses running up the middle of the board. On either side are rows consisting of (from outside to in) a 2-hole pad, three single-hole pads, and a 3-hole pad.

When building electronics project for permanent use - i.e. after testing on a solderless breadboard - you normally go to a #soldered perforated board of some type as a #prototype, or even for very-low-volume production.

There are different types of boards. I […]
