If you have read the HowStuffWorks article on Boolean logic, then you know that digital devices depend on Boolean gates. You also know from that article that one way to implement gates involves relays. However, no modern computer uses relays -- it uses "chips."
What if you want to experiment with Boolean gates and chips? What if you would like to build your own digital devices? It turns out that it is not that difficult. In this article, you will see how you can experiment with all of the gates discussed in the Boolean logic article. We will talk about where you can get parts, how you can wire them together, and how you can see what they are doing. In the process, you will open the door to a whole new universe of technology.
