At age 62 (18 months ago) I took a 1 day “ham cram” and got my technician license, and bought a couple of $25 vhf/uhf walk-in talkies. And played with homemade antennas for a while. A year ago I enrolled in my local community college’s Electronics 101 course, which meant resistors, voltage, current, capacitors, and inductors. And voltmeters and power supplies. Six months ago I took Elec 102, which are transformers, diodes, AC to DC rectification, transformers, and, voila, transistors. Next step: microcontrollers, sensors, and relays. Future: relearn imaginary exponents and Euler. It’s a _big_ field!
