EAT Meetings are the fourth Tuesday of each Month, at 6:30pm, at the GroundWorks space inside Holland District Library, 300S River Ave., in Holland MI.
Below are the topics of the video lectures by professor Richard Wolfson for September, October and November. After viewing the video lecture is a lab based on the lecture contents. The labs focus on providing hands on experience with components, breadboards, power supplies, DMMs, oscilloscopes, function generators and more. Often there is an amateur radio component to the labs.
Lecture topics.
September 24. Flip-Flop Circuits
By combining logic gates and positive feedback, obtain circuits with two stable states. These “flip-flop” circuits “remember” their current states until they are forced into the opposite state. Learn the inner workings of several types of flip-flops as they lay the foundations for memory circuits.
October 22. Shift and Divide-Your USB and Your Watch
Learn how electronic devices “talk” to each other by using flip-flops to send computer “words” one bit at a time, and observe how recipient devices reassemble incoming bits using serial-to-parallel conversions. See how Universal Serial Bus (USB) connections transmit communications between devices, and how the T flip-flop is utilized as a frequency divider in quartz watches.
November 26. Digital Memory
Examine the circuits that enable your devices to “remember” everything from contact information to your browsing history to the keystrokes you type on your computer. Compare random-access memory versus sequential memory as well as volatile and non-volatile memory.
Also keep an eye on the Herrick District Library website for upcoming events such as:
