But what happens if the same idea is used to create a low voltage instead of a high one? [D. Creative] has a soldering gun project doing just this, making a low voltage at a very high current.

Low voltage is defined as peak-to-peak QRS amplitude of < 5 mm in the limb leads and/or < 10 mm in the precordial leads. Note: If the gain indicated at the left of the ECG is turned down ...

There are a small handful of old tubes that need an impressively low voltage to work, though, and [J.G.] has put a few of them to work in this battery-powered audio tube amplifier. The key to the ...

Low-voltage deck lighting systems do this well and they’re safe and easy to work with. Unlike with standard household voltage, the transformer that powers them simply plugs into a receptacle.

A subset of linear voltage regulators is a class of circuits known as low dropout (LDO) regulators. This paper explains the fundamentals of LDOs and introduces Vidatronic’s LDO technology which solves ...
