   I got my laptop to play Taylor Swift on the AM band - https://www.youtube.com/watch?v=KH9yb1qFKDY by twiddling the memory bus (sounds a bit iffy ;) Code: https://github.com/anfractuosity/musicplayer Ba

   Very cool photos, nice to see rocks from a perspective I'd not seen before. I came across this recently - https://en.wikipedia.org/wiki/Thermoluminescence where it sounds like some rocks emit light upon heating.

   Thanks a lot, that's very interesting re. it using linked lists, and nice benchmark!

   Very cool! I'm curious when it says "did you know that accessing a random element in an array takes linear time", why that's the case, with bash?

   Has anyone come across many distributors for HD108 LED strips per chance? I've found only the bare LEDs on Aliexpress currently.

   Out of interest is there anything similar to the Ulanzi TC001 but with a slightly higher resolution.

    There isn't any way to allow certain streaming services via a firewall whitelist, but block all the extraneous connections a TV might make is there? (As the TV manufacturer might use the same CDNs/IP ranges as legitimate services?

    Has anyone used something like the FiiO CP13, I'm looking to play back and digitise some old cassette recordings. I've tried buying some old cassette decks from ebay before, but had problems with it starting to chew the tapes, so

    Cool, that sounds really interesting, what size film are you using that for? Is illuminating the film evenly hard too?

    Heh yeah, I split the area to be imaged into squares, and run autofocus in the middle of the square. Then use a 'snake' like XY pattern across that square to create images. But I need to dramatically increase the speed of this pr

    Thanks, I assume https://en.wikipedia.org/wiki/Coordinate-measuring_machine is what you're referring to, which look interesting, hadn't come across them before.

    I just added an extra image where you can see contours being drawn around the 'pits' of the CD-ROM. I need to improve the speed of the autofocus etc. before I can image a whole CD heh.

    I keep meaning to play with the NFC/RFID API, I got a little eink price tag I'd like to try changing the display of via the flipper zero. I created a very simple attempt at an oscilloscope type program ( https://github.

    By SLA, does it mean resin printing then using some kind of metal coating process? Or could you use something like SLS/SLM to print the whole model in metal?

    "The team is also working on a cheaper version of traditional transducers, which can cost more than $2,000 a piece" - Do these transducers require very high input power out of interest? Also what frequency does an acoustic modem t

    Thanks, that's interesting about the difference being in the aftertaste between Prince and Moutai. Will see if I can find a bar selling the Wuliangye one.

    Interesting re. herbal whisky, do you recall which baijiu you've had? Re. scotch whisky I've heard people referring to laphroaig as smelling of TCP. (I really enjoy peated whisky/smoked beers - I need to try mezcal don't

    I've got some Moutai Prince, it tastes pretty unusual to me I guess it is umami-ish. Anyone got any recommendations for other Baijiu?

    Are new drum scanners still being made out of interest? It appears fairly hard to find used ones. They sound a bit awkward to use from what I've read, as I think you need to use liquid to adhere the film to the drum correctly?

    Interestingly that doesn't appear to mention infrared from a quick scan, which is used to help remove dust as far as I understand. (I've got an old Canon FS4000, which uses IR)

    Well that sounds very interesting! I've got one of these https://github.com/newaetech/chipshouter-picoemp which is fun to play with, need to attach to my CNC machine sometime.

    No, that's true, I was under the impression there is an encrypted version though. Was thinking that could be combined with dead reckoning.

    Could that be done with a high powered laser, rather than wire, I wonder.
