I'm mostly interested in writing a series of programming and hardware design tutorials for my kid (and anyone else who might find them useful). I don't think I need anything fancy for this. Images, code with syntax highlighting and a few things. Not even sure if I want comments. He's been learning Python, so I'll use it as a way to expand his application of the language.

The rough curriculum I have in mind at the moment is:

    - Basic electronics concepts
    - Digital logic
    - Design a simple 8-bit microprocessor
    - Program it using the custom instruction set
    - Implement basic mass storage in Flash (perhaps via USB)
    - Implement a Threaded Interpretive Language (Forth)
    - Write a text editor using Forth
    - Design a number of I/O peripherals
        - 7-segment display
        - A/D and D/A
        - Dot matrix LED display
        - Various sensors
    - Build something useful, like a clock driving the n x m 
      LED display

This curriculum sounds really cool!
