Viewing profile — anfractuosity

Wouldn't line pairs / mm count as resolution.

Isn't the depth of field primarily determined by the aperture of the lens and focal length.

Really like Darktable, was playing printing a few photos at weekend from it, on my large-ish dye-sub printer - DNP DS80, works very nicely under Linux with cups (once I figured out…

Doesn't arch already package it ( https://archlinux.org/packages/extra/x86_64/darktable/ ), I was using darktable on arch, but recently switched distros.

There's a process some brewers use to treat water, to make it similar to a well in England, called burtonisation, using various salts

Maybe astronauts on the ISS could try a similar experiment ;)

Yeah, it's very cool, I found a rather interesting document on the chemistry to create a lippmann plate 'The True Colour of Photography' by 'Hans I. Bjelkhagen, Darran P.M. Green' …

Sounds very interesting. Just started looking at the paper, which seems very complex to me "An alternative approach utilizes light absorption via localized surface plasmon resonanc…

That sounds really cool, how did they do the DNA testing out of interest?

Maybe it was a Czech Mlíko pour ;) The faucets they use are pretty cool ( https://www.lukrfaucets.com/en/ )

I have a magneto optic sensor that can visualise the field lines of a magstripe when using a polarising microscope - https://www.youtube.com/watch?v=c8nM4Z-hkTw I'm going to try a …

Based on a repo I found that twiddled the memory bus, I transmitted audio from a wav file via Pulse Density Modulation - https://github.com/anfractuosity/musicplayer

If you PWM a signal, I presume you could add a filter to convert to amplitude changes?

I skimmed through a couple of youtube videos, would I be right in thinking the tracing is done always manually here. Would be really neat if it could trace automagically too, possi…

Wow that printer is fascinating! Good point re. film, related to that see - https://archiveprogram.github.com/arctic-vault/

Thanks! I came across http://www.pocketwatchrepair.com/how-to/jewels.php recently, hadn't realised the jewels weren't for aesthetics.

You can apparently lock shopping trolleys using the same kind of principle - https://www.tmplab.org/2008/06/18/consumer-b-gone/ And https://www.youtube.com/watch?v=LmSyb0kBvGE

Another 3D printed microscope https://github.com/TadPath/PUMA looks very interesting too.

Thought that podcast was very interesting. I bought the book - 'textbook of sake brewing' a while ago. I've brewed beer before, but rather fancy trying making sake.

I remember speaking to ALPA at a photo show, from what I recall the cameras also have very fine metal shims to align the camera to a digital back. Do they manufacture the optics th…

Great idea! https://www.mirror.co.uk/money/personal-finance/finance-expe... shows how little pubs make per pint, very sad. If anyone's curious about cask beer https://www.youtube.c…
