Construction techniques
"solderless breadboard" is the fastest construction technique ... but it is very fragile.
Dead bug style. Manhattan style. Veroboard. Perfboard and point-to-point. Solderless protoboard.
traditional perfboards with holes on a 0.1" grid (2.54 mm grid) come in 3 styles:
- just holes in insulator
- little donuts of copper around each hole, usually plated-through (See this robot controller for an example)
- solid sheets of copper, usually with a little donut gap around each hole.
The best one to use is ...
With these perfboards, there's 2 ways to connect wires so they don't fall off:
- wire wrap, or
- solder.
