Vac shredded some fall leafs and used them to mulch a garden bed.
I just spent 30 ish minutes making a 555 timer circuit to blink an LED to show my kids. The kitchen table is a long way from a university lab bench, I don't even have an auto-ranging multimeter. I had to use the random stuff still in my breadboard box and cannibalize a USB charger for a 5 V supply. But I was able to get an LED blinking at almost a 50% duty cycle on a 0.287 sec period. That really expensive piece of paper on the wall saying I'm an electrical engineer comes in handy I guess.
