I just used a hammer & nails to build a circuit – and I liked it!
Yes, I could rattle off a list of reasons to use more popular prototyping solutions, but none of them are as satisfyingly straightforward as nailing components to a board. Unfortunately, incorporating ICs into the build would likely be, well, tedious. Using the so-called “dead bug” approach would require soldering an individual breakout lead to each pin, do-able but less than desirable.
In any case, this highly visible ‘classic breadboarding’ technique seems a great way to introduce newcomers to schematics and circuit construction – just be sure to keep any mechanical components free of crumbs.
