This LED DC voltage indicator circuit is a voltmeter, rather than simply a battery tester. As such it may measure voltages as low as 3V. It utilizes. ... In high school, I knew more than the teacher ...

For the negative rail circuit, when the voltage across the shunt resistor exceeds 10mV ±5mV the output swings high and turns on the LED. There is no signal conditioning or hysteresis so if the signal ...

However, normally ozone is produced using lower voltage, smaller gaps, and large surface areas. Naturally, this led [Hyperspace Pirate] to investigate if a higher voltage method is effective at ...

The datasheet confirms this current, which is less than 0.5 mA but sufficient to light a high-brightness LED to an unacceptable degree. The indication was not “sharp” enough for me.
