Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I made a "laser-beam-break" camera trigger for my Nikon D750, which I use to capture images of hummingbirds at my feeder.

Instead of paying $125 for this ... (https://www.bhphotovideo.com/c/product/1337050-REG/pluto_tri...)

I decided to build one using an Arduino. I probably spent more than $125 on the project, but I ended up buying a lot of hobbyist electronics parts, soldering gun, etc.

I learned a bit about what Arduino can do, learned some baby electronics.

And I have some nice pics of hummingbirds.
