Welcome to Black Flag: A Coding Club Mission
In Marshall Trent’s Reunited Kingdom every citizen of New Edgehill has a neurochip implanted within them that links directly to the Neuralnet.
The Neuralnet sees and records every thought, movement and microscopic detail of every life in New Edgehill. Absolute control!
Cal Jones believes he is no different from everyone else. That is until he saves the life of Sasha and learns that everything that he thought was true is in fact a lie. He discovers an underground group, the Anarchists, living outside of the Neuralnet and harbouring a secret which will change his life forever.
Read the Book
Matt Langley has written a fantastic, imaginative and exciting novel for the Coding Club series. You can even read the first Chapter now: http://codingclub.co.uk/uploaded_pdfs/BlackFlag_sample.pdf
More info at http://codingclub.co.uk/black_flag.phpJoin Danni as you train as an Anarchist
This is a Coding Club mission. This means that you can get far more involved in this book than any other you have read before – should you wish to. To register for free, all you need to do is enter an activation code and fill in a short form. Unfortunately we cannot just leave activation codes in plain view. You will have to visit the Black Flag website and think like a true hacker – ignore the visuals and dig into the code!
I will guide you throughout your training as an Anarchist agent. You will solve many of the assignments that Cal, Sasha and I face in our struggle. Do not worry if you are still a novice programmer, there is lots of guidance and hints along the way.
All the preparation that is necessary is that you have worked through Coding Club: Python Basics. Alternatively you should be fine if you have learnt a little Python 3 some other way. You simply need to have a grasp of how to write variables and functions, perform simple maths operations and manipulate strings. You should also know how to save and load files in IDLE.
It is not going to be easy, but trying to save the World never is!

Solar panels are a clean and ecological source of electricity.
Obtaining this energy, however, poses a number of challenges for device designers. The amount of energy produced by the panel is strongly dependent on the angle of incidence and the intensity of the light falling on the surface of the cells. This, in turn, leads to unstable power supply parameters at the output, as even shading a small part of the panel may drastically reduce the efficiency.
The optimal solution to the above-mentioned problems is the use of a set consisting of a solar panel, a battery and a charge controller. Such a set allows to ensure constant parameters of power supply to receivers, and also to store energy produced excessively for later use.
The 30A-PWM-LCD solar charge controller allows you to connect panels connected to each other both in series and in parallel - remembering not to exceed the permissible values of current and voltage at the input of the device. Due to the operating characteristics of the PWM controllers, it should be remembered that when the panels are connected in series, the rated voltage at the output for charging the battery is 24V.
PWM stands for Pulse Width Modulation. PWM charge control devices can be explained as an electrical switch between batteries. The switch can be quickly switch on and switch off. Therefore, desired voltage can be obtained to charge the batteries. The charge current will be slowly decreased as the batteries charged.
