Hubble from Space and Integral-field Spectroscopy

*Hubble from Space and Integral-field Spectroscopy from the Ground: Seeing Both the Forests and the Trees

This is the Space Telescope Science Institute Lecture from March 2022.

A detailed, but also beginner friendly, in parts, introduction to spectroscopy also looking how this is applied and used in Astronomy.

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

ball shooter

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.

Propeller

This is a propeller test rig. Built By Harding Jenkins, uses 3 phase power supply along, which also allows rapid change of direction.

Transistor Amp

Talk from Harding on building a simple transistor Amplifier circuit.

Transistor Amplifier

I have finished building a transistor Amplifier. This is in preparation for the next STEM group meeting, on April 9th.

trans amp

As this contains a voltage divider, I have also built a few more resistor boards, with the view of presenting an activity around this.

How to Write a Scientific Journal Article Using Overleaf – Academic Writing Tutorial

This is an excellent short video on the advantages of using Overleaf for Academic writing.

There are several abrupt stops for adverts, but the video is well worth watching.

Resistor boards

This is a repost and update for a previous post. I am posting this here too.

As the next Paignton Library Stem Group meeting is

Date : Saturday 9th April 2022 Times : 11am –> 15:00

In preparation for the next event, I have been working on creating some electronics resources to demonstrate at the event.

These are quite simple to make, solder on headers and which ever component is needed for that particular board

Electronics 1

Various resistors 270ohm 330ohm 1k ohm 10k ohm

As of 23/3/2022 I have made up the following:-

  • 20K
  • 1 M
  • 2,2K
  • 15K
  • 80k

Which I hope to use for demonstrating voltage dividers.

A few pictures of some previous boards, that I have built up.

Electronics 1

Power supply, we need to get power from a battery to the circuit.

Electronics 1

Reed switch (not soldered), 1uF capacitors (soldered) and a switch block, not soldered as I want to figure out which switch block to use (I have a few)

Electronics 1

I have added a 3 way header as this allows for:

  • Components to be attached together
  • Branches in circuits
  • Connection of meters, scopes and other equipment

It should be possible to build a circuit that, internally will flash, for example an LED then use a scope to examine the frequencies at different points in the circuit.

I plan to solder up other component boards. Hopefully I will have something to demonstrate, but other visitors should be able to have a go.
