Default Kit Multi Meter Builders

This hand built tester is part of my arsenal now. I like the analog meter.

Did any of you ever build something like this?
It has (high ohms, injector, low ohms, 10,000 ohm voltage divider, etc.) switches and dials.

I've only figured out how to measure a 1.5 volt battery so far. It would be nice if I could do a little more than simple volt measurements.
I'd really like to be able to use the milliamps test feature.

Any help will be appreciated.

Well, your picture is not working, so it must be a video, which my computer won't display. I like analog meters for fast moving signals, a DMM averages over 5 seconds and will miss a low repetition pulse every time. DMM's, however don't load the circuit like analog. Here's a longevity tip. Every time you use the meter, put it back immediately to the highest AC voltage setting. That way when you plug it in the wall without thinking, you won't blow up the ohms or amps scale.
To use your meter, buy something broken at the charity resale shop, and fix it. I got a useful book for newbies at the resale shop, an obsolete trade school text. $2. Electronic Devices, electron flow version, 2 ed. Thomas L. Floyd. Shows you really how to use your meter to fix a DC power supply or simple amp. Nice diagrams. Good luck learning. Before doing any high voltage like tubes or amps above 10W read the "working on high voltage" sticky thread of the DIY audio tube forum about not killing yourself electrically. Anything above 24V can kill you, and below that will burn your fingers off if you wear rings etc. Knowing how do work safely with electricity is cooler than all the Harry Potter magic spells put together, I think.
