This project has been in progress for some time. In this final episode we will add the Volts, Current and Watts meters and test it out. This project is available on PCBWay, it consists of two PCBs, the electronic load and the monitor/display PCB. The monitor/display is optional, the load works well without it and you can use an external USB analyser or multimeter to monitor the current drawn by the load. As well as loading USB and PD supplies, there are 4mm banana sockets so you can use this to load any power supply up to 30V. Mulitload now available as a shared project on pcbway.com

I do the same with my Headers Det. I use coloured nail-varnish to mark them.
My wife loved going to the shop for the nail-varnish and letting the staff know she was getting it for her husband.
She would let them ponder for a while, then tell them what I use it for. haha.
Hi Tim - I have a bunch of these paint filled pencils on the bench in all possible colors. Better than your usual sharpie, b'c the color is visible on black surfaces. But I guess nail varnish will work, too :)
Nice Diy Tool 👍👍
Great project and a fantastic idea for a testing unit. Cheers
Heya, that looks like a nice project
Can you add an accumulated power meter to determine battery capacity?
Hi Dan - for us, this project is finished. Of course there are about a thousand different things that could be addded - we actually talked about something similar as you are proposing. But there's a time limit i want to spend on a project.
But - Source code and stuff is available on my channel! Grab the DL and modify away!
That's not enough voltage to use it for amplifiers, unfortunatelly.
