We will demonstrate how to build a miniature keyboard using a Raspberry Pi Pico microcontroller and a few resistors. This costs about the price of a street coffee and muffin.

In this tutorial, we'll show you how to build your own classic PONG mini arcade game using a Raspberry Pi Pico.

We fix our Van with a 3D print, and test a new solar power bank anm

This article explains energy, power, milliamp hours, kilowatt hours, and other units. We will give you the tools to do many calculations on how long devices will last on a power bank, how much electricity a device has stored, how much it would cost to charge an appliance, etc.

A deep insight to demystify voltage dividers & linear/logarithmic potentiometers with plenty of demonstrations and uses.

So many uses for these cheap and versatile break beam sensors. See how to make a light gate worth well over £100 for the price of takeout fish & chips. Plus bonus projects.

A great starting point to learn about Energy, Energy Stores, & Energy Transfers. Short introduction with plenty real life examples.
