My stuff
Bernice, funny you mention collecting vintage scientific equipment. One of my hobbies is an offshoot of my day job. I've collected and refurbished vintage laser systems over the years. Recently, the laser celebrated its 50th anniversary. One piece in my collection is one of the original prototype CO2 lasers from Hughes (Bell Labs actually got first light on a proof of concept model). Today, the CO2 is the industrial workhorse of welding and cutting in many industries.
I'm also an amateur astronomer of sorts. About once a year, I hold a telescope building class for local homeschooling groups. We build 4" reflectors from scratch. They turn out quite nice and rival the junk you see in department stores at $100 or so. Many of the students still use the scopes. It's nice to see I ignited a scientific spark. A few also helped me assemble my 8" beast. I can resolve Jupiter quite well, and even count many of its moons.
My volunteer teaching also extends to teaching holography principles (having the lasers helps). It's been awhile since it involves a little math and chemical use and is better suited for older students. But the students are able to shoot and develop their own 3D holograms of everyday objects.
I've also held classes in electronic design. Last year, using solar cells purchased on Ebay, we constructed several 80 watt panels for home experimental use. I wonder where those ended up?
On a more personal level, I assistant coach my son's soccer team. This is as close as I get to a field these days. An ankle injury has kept me off the field, but I intend on playing again.
My children and I also enjoy model rocketry, camping, skiing, hiking and a variety of other things that just don't come to mind right now
And yes, I've got the X1/9 and my 124 Coupe to keep me busy on the car front. I try to get out at least once a year and autocross one of those cars.
