As an add on to this activity I have developed a through hole PCB. You can see below the PCB file produced on a program called Proteous and images of the completed PCB. Please see Diamond+ Electronics - Printed Circuit Boards (google.com) for more information on PCB's.
If you wish to solder up your own Astable PCB please have a chat with me as I will probably have some spares for you to have a go with.
If you are a regular to our lab sessions in Sheffield you will probably be able to spot that this is the circuit used in our Workstation lab - you can see how it was developed here from the prototype board to the completed PCB.
