Brian Lough | Cheap & Quick Inline Volt & Amp Meter! @BrianLough | Uploaded August 2018 | Updated October 2024, 5 days ago.
Build yourself a super cheap and easy inline volt and amp meter using only $3 worth of stuff.

The video is longer than how long it will take you to make this!

It has a standard 2.1 DC input and 2.1 DC ouput so you can place it inline with a tonne of different projects and devices. Supported voltage 4 - 30V, max amp is 10A.

This was just a proof of concept, I will make a more permanent one later down the line, but really happy with how it came out.
