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:

- 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:

First we need to measure our elements.

Then draw rectangles on paper with elements dimensions.

Glue it to case.

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

Put everything in :)

Step 3: Soldering:

Now we can solder our wires:

Step 4: Test:

Little movie with test :)
