Explanation
Explanation: 

This experiment is in the process of being made but hopefully will be useful for a wide range of circuit based experiments. I've bought the following pieces to make up the components.
Opamps, transistors, capacitors, motors, solar panel, resistors, logic gates, timers, leds, diodes, thermistors, photoresitors, nickel wire heating element. I'd also like a dynamo for other power input but haven't got this yet and some links to electromag experiment.
Idea is playing with circuits and building things.
Plus aim could be an adder using logic gates, feedback devices using Opamps, fire alarm using themisotrs, light alarm,.
There'll also be places where you can clip in materials to see how conductive they are, I have some bits of wood, perspex, nickel, and bits we can see how conductive they are.
