I have a little envelope of cores that I’ve been meaning to do something with for years, but they are just so tiny I haven’t wanted to mess with them. (Not sure when they were made, but I’m assuming fairly late based on the size.)

I’m not saying that wouldn’t happen, just that there isn’t a law allowing it :)

In what country? I'm only familiar with rules in the US, and it isn't the case here.

It was a huge advancement. Previously they were computing numberwang on slide rules.

Oh, fascinating. The latest one was definitely monohydrate - maybe I was using HCL years ago and just don't remember. I'll look into that. Thanks!

I feel like for me it would be thwarted by the fact creatine seems to completely mess up my sleep. I don't remember that from when I was younger, but recently tried adding it to my diet and had to bail.

Omnipod for the win. But, yeah, I have a bunch of disposable needles in my kit as a backup.

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...

Or just bring a bunch of disposable needles with you and draw from your vials that you already have for filling your pump.

Very cool.

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 hope I don’t miss it when you post!

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 :)

I don’t know how niche they are, but a few I’ve done in the past

- 3D printed musical instruments. Print other designs or contribute your own

- lock picking. When you really get into it, you modify locks to make them more of a challenge and mail them to people

- Ham radio is hundreds of sub-hobbies in a trench coat. I’m currently mainly interested in linearizing switch-mode amplifiers, but was doing fox hunting for a bit (radio direction finding), and periodically do POTA (transmitting from parks)

Ooh! What kind of capsules?

I don’t know what the regulations are in your country (looks like you are maybe in Canada?), but in many countries it is straightforward to get an amateur radio license, and then you can have all sorts of fun (under the rules).

Amateur radio is pretty approachable and has lots of opportunity to go down those rabbit holes.
