Education and Training, “E.A.T.” meetings are the fourth Tuesday of each month, at 6:30pm, at the GroundWorks space (on the west side of the first floor) inside Herrick District Library, 300 S. River Ave., in Holland MI. All registrants under the age of 18 must be accompanied by a parent or guardian. Registration opens one month before the event.
Below are the topics of the video lectures, “Understanding Modern Electronics” by Professor Richard Wolfson of Middlebury College. The course consists of 24 lectures that provide a conceptual explanation of the principles of how electrical circuits work and are used to control everyday devices in our modern world. Components and topics that are covered include transformers, transistors, resistors, capacitors, diodes, semiconductors, Ohm’s Law, and analog and digital levels.
Lecture Topics
March 25 – Analog to Digital
Observe how circuit designers have formulated a wide array of schemes for converting analog signals to digitally encoded information. See how flash converters, integrating converters, and feedback converters use very different methods to accomplish the same goal, and weigh the situational costs and benefits of each.
April 22 – Your Future in Electronics
With some final tips, an introduction to the microcontroller, and a demonstration of an amazing circuit aimed at improving the efficiency of photovoltaic panels, Professor Wolfson leaves you with an enhanced appreciation for the complexity of essential modern electronics. You are now well equipped to embark on your own journey through the fascinating world of electronics!
Also keep an eye on the Herrick District Library website for upcoming events such as:
Tech Help Open Hours – weekly, 2P-4P see web page for dates.
Got a tech question you just can’t figure out? Need help with email on your phone? Drop in and ask us your questions. We can help you find out the answers.
Basic Circuit Board Design – Saturday, March 22, 10A-2P
One of the key concepts in electronics is the printed circuit board or PCB. It’s so fundamental that people often forget to explain what a PCB is. This workshop will breakdown what makes up a PCB, some of the common terms used in the PCB world, and show attendees how to design their own circuit board using the Fritzing PCB designing platform (FREE).
Quilted Dinosaur Cat Toys – Monday, March 31, 6:30P-8P.
(Just seeing if you’re paying attention, but this is for real. The library has something for everyone!)
Holland Repair Cafe – Saturday, April 26, 10A-2P Throw it away? No way! Help keep items out of the landfill by learning skills to make your own repairs. You’ll also find tools and materials to help make repairs and connect with local community volunteers who have experience repairing clothes, textiles, and other household items.
If you have questions about amateur radio equipment, operating practices, licensing, test and measurement, or anything remotely related to amateur radio, this is the place to be. And, for more information regarding anything connected to the E.A.T. meetings, please contact Jeff Nonhof, KD8THX, the program’s originator, leader, and just general guru of all things radio, computer, and electronics related. (His email is on his QRZ webpage.)
HARC education and training sessions are open to the public and you do not need to be a HARC member or have an amateur radio license to attend.
