Looking for a project volt and amp meter on LCD

[Kakashi]

If anyone came across an volt and amp meter on 16x2/1 lcd project please share it. I need something that measures up to 100V and 50A for electronic(dummy) load.

The only project I found is this one, but it seems its buy only available:

Or I'm too blind to find the hex file...
