Even so, travel is stressful. My carry on is full of backup pods/sensors. But now that my insurance is being annoying and only filling a month at a time, I don't always have an extra...

Just fyi, the GitHub links to some of the docs (like self-hosting) give 404, as do some of the internal links in the docs.

I’ve wanted to make a ribbon mic but haven’t gotten around to it. I’ve seen where people use Mylar emergency blankets as the membrane for condenser mics. The closest I’ve gotten is accidentally having a capacitor in a radio act as a microphone where it shouldn’t :)

Now, as for "did I proceed with more serious learning" - I alternate though a ton of hobbies. So I moved on after that, though still go back to it from time to time. But I also have other musical interests and it was helpful to those as well.

Also did a lot of music on the commute on my iPhone with Korg Gadget (and Caustic before that). Sometimes with a keyboard, sometimes without.

Because I loved the Fluorescent theme.

I've wanted to make this the Openflexure Microscope (https://openflexure.org/projects/microscope/) but it is behind the backlog of all sorts of other things.
