Helps a whole lot! I have another question, but I think it isn't as hard as the previous. What would I need to learn before trying this? What are some good projects to learn these skills?
Start with some simple electronics projects like:
Try building one of these - its worth it for practising your soldering, plus it makes groovy chippy noises *Grin* and gets you used to placing components on a 'board' of sorts - in this case stripboard...
Also another thing you might want to try is buying an old radio or personal stereo at a charity store and open it up / remove the guts and explore practising desoldering the components (battery powered devices are safer to practice on)
