I like to build a lot of circuitry, but the voltage regulators that most IC’s require get annoying when you have to keep on buying them and putting them into each board you want to power. This is a very simple little device that will take the voltage coming from a power outlet in your […]
Although it sounds like some kind of euphemism from Brave New World, a “pneumatic trough” is actually a very handy piece of classic chemistry lab kit.
