Are there any downloadable elect. courses available?

I have long commutes, & it would be really beneficial for me to be able to download podcasts/lessons of electronics courses to listen to while on the road. I'm not quite a beginner in electronics, but close to it.

I have done a bit of searching & haven't been able to find any of these types of courses out there.

Does anyone know of any resources for this?

Thanks, kat

The problem is electronics isn't something that can't be easilly taught using an audio CD or MP3 because you require schematics of different circuits to teach it properly so a book is normally the best choice.
