    I never did work it out myself. Sometimes I was fine. Other times I didn’t sleep for 3 days. Was “sort of” independent of stress and so on, although higher average stress levels made it a little worse. Or maybe stress just feels worse combined with sleep deprivation. I tried various changes to my habits over the next few years, none of which made any difference – although some were good for other reasons (e.g. getting into better shape, eating better, and so on).

    Went to go see a doctor. They brushed it off, so I went to go see another doctor. They prescribed a low dose of a sleeping pill.

    Problem solved forever with no noticeable side effects. I think I’m on 1/2 the pediatric dose or something. Amazing how so little of something can make such a big difference in my life. Wish I had gone to see 2 doctors earlier.


  • Well, I had heard of someone that got a little amplification out of them at 3.3V and a weird configuration. It was a different tube, but I figured I’d give it a go at 5V.

    My tube was old and originated from a junk pile in Japan. I figured it wasn’t enough entropy to just use an unknown tube the wrong way, so I added some random scrap parts from the Soviet Union. The tube produced amplified output, but the output impedance was way too high when being used this wrong way (in other words, it couldn’t drive a speaker). So I added some completely unknown Chinese amplifier IC as a buffer.

    It’s approximately pocket-sized. For a large pocket, anyway. The tube heater gets the whole thing warm. It produces hilariously distorted (but sort of cool) sound. I call it a ‘themionic pocket warmer’, arguably not so useful here in Vietnam. The audio function is secondary. I suppose if you are a half-deaf Antarctic explorer with a deep love of stovepipe hats, it would be a good hat-warmer as well. I guess that’s the target market :D

    I threw some photos up at voltage.vn. It was a fun way to spend a couple of hours.






  • I found a neat set of old ink blocks from a famous manufacturer in China. It’s technically worth a fair sum of money, I paid 8$. Also an old vacuum tube for 3$, got it working. Neither of those are useful though, just neat.

    In terms of materially useful things? Well, someone taught me how to use old, no-electronics camera lenses. So I bought a used DSLR for 135$ and bought antique lenses for very cheap (again 8$ for something that was originally nearly 1k after accounting for inflation). Now I can do my own product photography, documentation, etc. and it cost me very little, but looks great! Also my vacation photos have skyrocketed in quality.



  • It’s predatory garbage – I’ve had some VCs as customers and I guarantee that if the IPO was expected to do well, they would not leave a dime on the table for contributors. Generally if you don’t know who the bag-holder in these schemes is… chances are it’s you!

    I still help out people on Reddit, because a lot of foreigners don’t know how to do things in my country (e.g. find medication they need) and that’s where they ask. If it vanishes tomorrow, I don’t really care though, haha.
