I finished the second half of my oscilloscope basics lesson, broke out the Arduino UNO, chased a weird waveform, and learned why AC coupling is not what you want when probing a digital pin.

I finished the first lesson in my electronics curriculum: multimeter basics. I measured a fresh AA battery, checked a cheap bench power supply, learned what the dial markings actually mean, and corrected my first wrong electronics definition.

There's a lab at work where people build things. Actual physical things. I walked in, saw laser cutters growling and 3D printers humming, and immediately ordered $400 worth of electronics gear from AliExpress. I have no idea what I'm doing.
