Things I've thought about. Things I've looked into, ideas from making, technical notes, discoveries, and things worth leaving behind.

Things I'm trying. Experiments, tests, prototypes, and unfinished ideas. This is where I keep whatever I'm working on right now.

Things I've made. Websites, software, hardware, electronics, and small things built for no particular reason.

Things from the past. Finished, abandoned, discontinued, old projects, and old ideas. Not everything needs to disappear just because it is no longer active.
