Humble Bundle has a ton of electronics books right now, and Make electronics is one of the ones you can get for $1. Quite a few more, but you have to pay upwards of $15 for them. It is in .PDF but considering that it goes for $30 on smallbear, its a pretty good deal.

Thanks for posting this it looks excellent.
Damn, nice deal. Thanks for the heads up. So tempting to drop $15 just for the synth book
