Introduction: Simple Ammeter and Voltmeter Box

Picture of Simple Ammeter and Voltmeter Box

When I test devices with for example 12V supply I want to know voltage and current. Also I hate to disconnect plugs, so in this box is switch to easy on/off power.

Step 1: Materials:

Picture of Materials:

- one switch

- one panel ammeter and voltmeter module from ebay/aliexpress

- one box/case (I use z73)

- one power socket

- one power plug

Step 2: Customize Case:

Glue it to case.

Drill holes for elements on top, and for input and output.

Put everything in :)

Step 3: Soldering:

I will advise builders to not run inductive loads like motors with these meters inline, you will fry the board and please, don't ask me how I know this. ☺
