Schematics are the functional diagram of electronic circuits. With so many designs available on the web, understanding how to read schematics can unlock a world of possibilities for the electronics maker. In fact, if you can read a schematic, you can build a circuit before even understanding how it works!
Fascinating video from Nyle Steiner, who reports on his experiments with simple homemade memristors made from what are, probably, Al-CuS-Cu and Al-PbS-Pb junctions. He describes the observations that led him to experiment with these systems and the results of his experiments, and then wraps up by drawing out a simple memristor demonstration circuit and demonstrating its operation on-camera.

Infrared light may be invisible to the human eye – but it’s usefulness in the world of electronics is easy to see. IR emitters & detectors can be used in a variety of different ways – most of us use them for wireless communication everyday.
More cool original content from Hack a Day, this time by Kevin Dady. He writes: “I was recently commissioned to make a device which uses a pretty large number display, and I went out shopping. The seven segment we liked best was still quite pricey, and would not fit our enclosure correctly anyway…”
This lovely hand-made component, built as part of a crystal radio set Instructables user Jezan assembled for his son, started out as a sheet of 1.5 mm aluminum that looks like it may have come from the side of an old file cabinet. Jezan used minimal tools…
Easily overlooked, but elemental to electronics hardware, the manually operated switch is the simplest of electromechanical devices — and likely the most familiar. While the most basic switch is … well, quite basic — there’s a crazy-huge variety of switch types & sizes available to the electronics maker nowadays. Those new to the soldering & schematics scene will surely benefit from an introduction to some of the terms and formats relevant to various switch species.

When you think – “DIY electronics”, one of the first images that likely comes to mind is a bunch of parts and wire soldered to a standard piece of perforated circuit board – and that makes sense. Perfboard is super-versatile – essentially it’s just a grid of potential solder-point connections. You can trim it down to just the size you need – or leave extra space for future enhancements … or revisions, if need be.
