I like to check my Power banks have the capacity that they claim to have. BlitzWolf were confident enough to send me one of theirs to test and in this video I explain my testing method.

It's been a year since I put my 7s4p lithium ion pack into service in the shed so I thought it was time for a bit of a review on how things had gone over the last year.

I enjoyed building this ATMega328 based transistor tester. It identifies and tests a wide range of components and displays lots of information and a useful diagram.
The testers instructions are fairly basic, but the circuit board is well marked to make it easier. There is one basic test to complete before you can use the tester, and one calibration exercise where you have to watch the screen carefully to know when to do what.
It can also be used as a simple function generator and it creates a PWM duty cycle from 1-99% which are handy features.

It's no surprise that shading causes solar panels to produce less power, but what happens when you have one shaded in a pair of panels?

After buying a boat load of 555 timers I needed to find out what they did, and how I could use one or two of them.
In the end I decided they could be used as a basic solar charge controller! It's not smooth sailing though...

Can you charge lithium Ion cells on a standard lead acid solar charge controller? I've read lots and I'm not entirely sure - so in this video I'm going to start testing it!

The diyBMS needs a central controller which is used to monitor and control all the cell modules and therefore the whole lithium pack. In this video I build the it and program the thing.
