In this ongoing class, you will learn about what makes computers work from a hardware and software perspective. This class is at an appropriate level for an advanced 11 or 12 year old. Otherwise it is good for a 13 to 16 year old who is interested in the details of how the circuits in a computer work, including transistors, logic gates, the binary numbering system, binary arithmetic, processors, and low level programming. Below is a list of topics that we will study for the first several weeks. The list will continuously be updated so you know what we will be studying and choose classes that most interest you. You are welcome to join any week that interests you or stay for several weeks to gain a broader understanding of how computers work. 
Week of February 12: What is a Computer, The History of Computers, and Transistors and Electricity
Week of February 26: Electricity, Transistors, and Logic Circuits
Week of March 5: The Digital Numbering Systems and Binary Arithmetic and Circuits
Week of March 12: Build a Binary Adder/Subtractor Circuit
This class will be structured as a lecture with students interacting through chat and/or video. Basic math up through multiplication and some knowledge of exponents recommended.
