Circuitry for the brain

Are you socially handicapped by your lack of electronics knowledge? Wishing you could remember more from school physics/IT lessons? Ever wondered what these strange transistor things are and why they were so important?

I’ve just come across a very nice site called JeeLabs by Jean-Claude Wippler – thanks, Aideen – and in particular a set of posts called Easy Electrons, which introduce resistors, capacitors, diodes, transistors, and some of the things you can do with them.

It’s not a series for complete beginners – you need to have some grasp of voltage and current and the relationship between them – but if you’ve ever wondered “Do I need a resistor with this LED, and if so, why, and how big should it be?”, or “Why is my transistor getting hot?”, then this could be useful reading.

I liked the ones about diodes and the set of posts about transistors….

To create not a block, but an inline code span, use backticks:

Here is some inline `code`.
