I have no affiliation with Mike and Key, but in my opinion this is the best electronics swap meet in the greater Seattle area. I go every year. (If you know of others, post in the comments!)
The Mike and Key flea market will take place on Saturday, March 10th at the Washington State Fairgrounds in Puyallup. Doors open at 9AM (earlier for sellers). I’m looking forward to meeting other PNW electronics and ham radio folks there. I have a seller table again this year so I should be pretty easy to find. I’ll be selling a few kits along with ham radio gear and miscellaneous electronics.
Mike and Key hosts ham radio exams during the swap meet, so if you’re interested in getting a ham radio license this is one opportunity. More details on the event flyer.
A MightyOhm Geiger Counter samples radioactive decay from a martini glass that contains a small amount of uranium. If the number of clicks in a set period is even, the robot dispenses vermouth into the glass. If the count is odd, it dispenses gin, therefore creating a wet or dry martini based on the random process of radioactive decay.
