You may have seen this on MakeZine already, but if not (and you’re interested in learning more about electronic circuit design), check out these enlightening “Web Lectures” by CompSci prof Bob Brown. The very clearly written short articles cover simple electronic circuit design, logic gates, and digital logic basics. The coolest thing about these is Prof Brown’s use of JavaScript to create interactive figures that you can switch on/off to see how the circuit or logic gate functions. This is a very easy and visual way of understanding how logic functions in circuit designs and how Boolean logic works.
