Bob writes: Back when I was deverloping the PSU burner, I wanted to have the Analog Discovery isolated from the common ground, to avoid noise and other issues. Since I did not have a way to do this, I ended up using a laptop on battery for measurements. But...Tags: analog, Analog Discovery, isolator

tanishqjain340 wrote this instructable detailing the build of his analog calculator project: Do simple calculations with your math box. The next time you need to crunch a couple of numbers, resist the urge to grab a digital calculator. Instead, round up some variable resistors, also known as potentiometers, and wire them into an...Tags: analog, calculator, instructable

DIY Audio function generator is a low-distortion function generator which operates in the Audio frequency range. Conventional function generators use a square wave signal to generate the other waveforms like triangle, or sine wave. This approach adds noise to the sine wave output, which is the one waveform Eric wants...Tags: analog, Function generator, Project Log

Oscar has written an article describing a technique he's used for reading multiple analog sensors with one MCU ADC pin. He was designing a line-following robot and wanted to read several infrared sensors without having to dedicate an analog read pin for each. His solution uses "a Schmitt trigger inverter...Tags: analog, Schmitt trigger

This amplifier with an analog voltage multiplier could be useful in a bench power supply: Combining a high-side current-sense amplifier with an analog voltage multiplier, the MAX4211 can easily measure the power dissipated in a load. One multiplier input connects to the load voltage, and the other to an internal...Tags: amplifier, analog, power supply
