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.
Magnesium Taurate is the form of magnesium I settled on. I take 1500mg of it (300mg elemental Mg) every evening before sleep, but I feel that even half of this dose has a noticeable effect on my sleep.
Magnesium Glycinate was destroying my sleep even when I took it in the afternoon. I'd wake up after 4-5h of sleep and would feel completely alert as if it was midday and then tiredness would slowly ascend on me over the next few hours but I'd still be unable to fall asleep.
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...
I'm fortunate to have the income to support buying backups when I had insurance issues. During the Dexcom G6/G7 switchover and the switch to the Omnipod, I had just filled a bunch of G7s but the Omnipod didn't support it yet, so I ended up having to buy G6s out of pocket. Even with coupons from the manufacturer, it was still costing me $200/month.
When I lived there (or visit family), a Costco Gold card and store pharmacy visit can help a lot - it was around $150/mo for G6 last September. I'll switch over to G7 some time this summer. The Costco plan more than pays for itself using the built-in rewards program and rx discounts if you're paying out-of-pocket.
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)
HAM radio is whole range of things that were not possible when I was getting into it - first of all it's super cheap to start now, and you can probably bounce RF signals off the moon for less than $100 nowadays.
Shortwave radio has always allowed signals to go around the world (by bouncing off the stratosphere). Most likely the new digital + AI capabilities means that a few well positioned relays could make for a very independent, low bandwidth Internet.
Solar powered BTS or APs all kinds of experiments are possible...
Lock picking is great! Many security conferences will have a "lockpick village" where there are just a bunch of locks, lockpicks, and volunteers teaching people how to do it.
I am trying to dial down K67. I am thinking about gold plating myself for the diaphragm in the future, but I am not ready for the expense. It is the hardest part of the project because the sound quality mostly depends on the diaphragm quality, and the rest of the capsule is literally a container.
I started the hobby a while back when I tried to create an ESP32 field recorder, but the sound quality was terrible with the MEMS style micropones. I ordered the Japanese Primo mics (14db for 10mm is crazy), and said if Japanese dudes can do it, I can do it too.
I was trying to create a visualizer tool for my steps in the backyard with ESP32 microphones, which sync perfectly and analyze the sound locations with Time Difference of Arrival (TDOA) methods. I got close, but mic sensitivity, even at 14db is not 100% unless I place the mics 30-40 inches apart. I am still working on that project, but that also got expensive because $28 for ESP32-S3 POE and $25 primo mic per node got very expensive quickly as I wanted to cover more areas. I hope to share it soon with HN.
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 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).
Transmitting on AM broadcast frequencies is generally prohibited unless it meets an extremely low-power exemption , even if you have amateur license(I have a Japanese amateur radio license). A practical way to reduce risk is to put a large resistor before the antenna so the radiated power stays within that exemption. You could start with 100 MΩ; if the receiver cannot pick it up, try 10 MΩ, and so on.
There's still one example of a working offshore radio ship, the Ross Revenge in southern England which you can go and visit. She's one of the former Radio Caroline ships, the studios are still fired up every month for a weekend of broadcasting and they run tours. Radio Caroline themselves are still alive and kicking as a legal station broadcasting 24/7 online and on 648 AM; ironically the latter transmission comes from a former BBC World Service site. She wasn't really a 'pirate radio' ship as she was a Panamanian-flagged vessel in international waters so not subject to the Wireless Telegraphy Act in theory, but British citizens specifically would have committed an offence working on her in her free radio days. What really did Radio Caroline in as an offshore broadcaster was the Anglo-Dutch action against the clandestine organisation which supplied the ship, that and the move from a 3-mile to a 12-mile limit which forced her into more exposed waters.
Other than the RNI ship she was probably the best-equipped radio ship that ever put to sea, and certainly the strongest. She was a long-range trawler built for Arctic conditions, and the engineering which went into the radio station was really impressive; Peter Chicago her engineer by all rights should be up there with the greats in hacker lore. Most radio ships were clapped-out old vessels at the end of their lives, they were essentially slapped with transmitters and sent to sea to die since you can never take a radio ship back into port once it's broadcast. The Ross Revenge on the other hand was a very strong ship who was left purposeless midway through her life due to the Cod Wars. The generating and transmitting facilities were really sophisticated for radio pirates, there were plenty of redundancies and the ship could radiate multiple medium and short wave services.
The broadcast studios and accommodation are still active but most of the machinery spaces and the hull itself aren't in good condition. They've raised half a million pounds for repairs, but that's not actually all that much in the maritime conservation game. Hopefully it will be enough to stabilise the immediate problems with the hull and open a door to lottery funding though. If you're in the area I'd go and see her while you've definitely got the chance!
With Zynthian OS up and running, the full list of plugins shows in its webconf page, it's so long that they have to hide basically most of the plugins from the main on-device UI.
Roughly speaking, if it's open source, most likely it will work. If it's proprietary, assume that only Pianoteq and a small number of u-he plugins will work. Most commercial products with binary-only distribution don't feel like RPi devices are a large enough market for them to build binaries for it. Even if they otherwise offer ARM builds for Apple Silicon and Linux builds for x86.
kxstudio supports rpi, it comes with a few DAWs and a great deal more, it is probably your best bet for this stuff on pi unless you want to compile stuff yourself.
