March STEM Group Write up
The March meeting was again busy. This month we had a demonstration of a model propeller test rig from Harding Jenkins, after which we had a short talk on the basics of building up a simple NPN transistor amplifier.
Next month Harding will be able to build on this and explain a few more concepts, which includes describing waveforms for class A, B and C amplifiers. The latter can lead to pulse formation. This can then lead in to discussions on digital logic.
We still had people coding in Scratch, web coding and
I did a quick demonstration of a tri colour LED connected to 3 switches, which when activated can illustrate colours formed when primary colours are mixed.
Primary : Red Green Blue Secondary : Cyan Magenta Yellow
Demonstration of a ball shooter project, this has two rotating discs, which propel a ping pong ball forward. I think this is designed to teach about momentum, speed, propulsion etc, adding energy to a mass allows it to gain momentum. Please feel free to offer a better explanation, in the meantime it is a fun project.
This is a propeller test rig. Built By Harding Jenkins, uses 3 phase power supply along, which also allows rapid change of direction.
Talk from Harding on building a simple transistor Amplifier circuit.
