Not sure what a show and tell is, I guess my laptop with tons of stickers, and boot up something that looks hackery. Besides that, my guitar perhaps?

Climbing gear or 3d printers.

My favorite rock. Its just neat.

My Teenage Engineering Pocket Operators.

I fuckin love these things. I used to feel left out when my friends would try to play music together, but then I found a way to be involved with a few mini-electronic-drumkits.

You can sequence a bunch of them together and sync them, easily, as well.

Teenage Engineering makes a bunch of other cool shit, too. I'm not much of a musician, though, so most of it is way beyond me.

I built one of those Ben Eater 8 bit breadboard computers, which I'm pretty proud of.

Probably my wheelchair. It's a pretty nifty little chair that has quite a few unique features. Also I would need it to get there anyway. Otherwise maybe one of my drawings.

My radial arm saw.

If the timing is right, I would bring a mushroom grow bag with mushrooms sprouting.

If not... probably my radiacode gamma spectrometer and some of my radioactive items. Maybe a clock with radium painted dials and a piece of trinitite. I think that there are many different points of discussion that can be of interest to a broad audience (radioactivity, spectroscopy, electronics, US labor law story of the radium girls, nuclear explosions, background radiation.... etc). As a bonus I can bring a UV flash light and show the radium fluorescence. Adults love UV flash lights.

Somethings ESP32 related. Meshtastic radios, a controller I am building to add some features to my car.
