I have an Arduino, and I want to make it do things. I gather that what I really want is a Raspberry Pi in addition to my Arduino. The trouble is, I don't know Python and my C and circuitry skills are severely rusty. So do you know of any online courses or physical books that will teach me all of this as a general subject of "making devices" rather than individual Python, C, and electrical engineering courses of study?

How can we make music play when a door is closed? [more inside]
I like songs that evoke images of circuitry, complexity, and digital processes. What are some songs and artists that convey this feeling? [more inside]
I would like to learn more about electronics and circuitry by making a LED light panel. I have questions about how to calculate the number of LEDs I need, soldering, and how to diffuse the light. [more inside]
I want to create a digital timer to run a motor and activate three solenoids in a particular sequence and for particular durations. [more inside]

Timer and Control Circuit. I need to measure the rotation of a spindle and the time during which a circuit is thrown open during that rotation. I think I need a clock, a counter and a software interface. Where do I start? [more inside]
In tube ciruitry, what is a "starving plate" design?
Just a stupid question that's puzzled me for years: Why is it that, on electric fans, the order of the settings on the switch is OFF - HI - MED - LO? I'm sure there's an electrical reason for this, but I don't know what it is, since I know nothing about circuitry. One would think that OFF - LO - MED - HI would make more sense. Can someone explain this to me?
Where can my sister (in London) find or buy dead printed circuit boards for an art project? The larger the better, the cheaper the better, what they used to be doesn't matter.
I want to learn how to make simple electronics, like LED controllers that I can hook up to a serial port. Can anyone recommend a book to get started with? [more inside] [more inside]
