Ugh. Looking for one particular component. I cleaned and sorted my stock of parts 18 months ago, and it looks like it's time to do it again 🤷♂️

(Not shown: soldering iron and tools, scope/meter, various hand tools, coffee)

Staying in a delightful B&B in far, far northern Wisconsin, on the Lake Superior shore.
It's lovely, great service and staff, and wonderful food (catering to my Celiac disease).
However.... I just noticed this window in the room and my eye is starting to twitch.
