Electronics Scout Badge post 2002

The Scout Activity badges from post 2002 are circular with the Activity image on a blue background with a red border. The Badge is worn on the left sleeve starting from the shoulder and going down in order of achievement.

To earn the Electronics Activity Scout badge they must achieve the following

1.       Show an understanding of components by completing the following three tasks:

a.       Be able to recognise common electronic components that are shown to you. Explain, in simple terms, the functions they perform in electronic circuits.

b.       Understand the systems used for marking components with their values and be able to identify the values of resistors and capacitors so marked. Understand the importance of the rating of a component.

c.        Know the symbols that are used to represent common components in circuit diagrams. Show how to identify the polarity of a diode and a specific pin number on an integrated circuit.

2.       Demonstrate knowledge of safe working practices to be followed when handling electronic components, and circuit boards and when undertaking soldering.

3.       Use a multimeter to measure voltage, current and resistance in a simple circuit. Discuss the relationship between these values.

4.       Discuss the main differences in operation of digital and analogue circuits.

5.       Construct three simple circuits, one of which should be based mainly on digital electronics. These may be from a book or magazine, or circuits that you have designed yourself. 

At least one of the circuits should be soldered using either strip-board or a custom made printed circuit board. Explain the principles behind the operation of each circuit and the typical values of voltage and current found in each.
