Please count me in if these ever gets going -- I'm a relatively recent transplant (moved here 2 years ago) but found it very easy to plug into the local security scene (Black Lodge Research, Harry's on Thursdays, HushCon, etc.) and while they're fun to hang out and meet other folks in the space, I've been looking for a more hands-on tinkering meetup with clearly defined goals (we are going to learn about XYZ today).

P.S. if you're a hardware nerd, you might like https://dma.space/ (just had their grand opening this weekend) over in Capitol Hill.
