Acoustic analysis of the electric grid sounds interesting, is that to detect things like sparks?

Since as far as I understand the UV light also acts as a mutagen, wonder if you could potentially create some interesting new yeast strains for brewing. It might also be interesting to use a dye to highlight dead cells.

Yeah I do remember hearing good things about the Epson scanners, will have another look, thanks.

Hmm, does seem pretty expensive but sounds interesting. I've got an old Canon FS4000 for 35mm, which works ok for me. I'm curious what people recommend for 4x5 film. Is there such a thing as a cheap drum scanner.

Has anyone bought un-cracked geodes before? I've not had much luck with those so far.

Do you have a link to that, sounds cool?

A linear scanning mechanism would be a lot faster still than the XY approach. I'm very curious how expensive sensors are though, that capture this data in a single shot, I've not seen any prices so far.

Yeah definitely, I've not looked at papers relating to microscopy with hyperspectral cameras. That might be especially interesting with samples that fluoresce.

The much faster way is to move a slit in front of a diffraction grating and use a 2D sensor behind that, that way you can obtain multiple spectral patterns simultaneously, see the video I mention at the start - https://www.youtub

Thanks for the link, not come across that before.

The hardware itself doesn't appear to be open though? - "Blueprints are available on case by case basis"

It seems a bit disingenuous to call it holographic doesn't it? I believe https://en.wikipedia.org/wiki/Integral_imaging is the technology. It has similarities with lenticular prints. I found this print that uses

Why wouldn't propagation create further glowing plants, they're genetically modified?

https://light.bio/ looks more interesting than injecting glowing substances Heh, I just came across this though "Our Firefly Petunias are protected under patent, and as such, propagation and breeding are not permitted.

Cool, thanks for the heads up!

Nice article, I came across very cool Python library recently too re. colour science - https://www.colour-science.org/ Just started playing with it with my spectrometer based on one of the examples they have, to convert spe

Interesting thanks, that's faster than I thought it'd be.

Very interesting, curious how long it would take to brute force the 56 bit key, with something like a GPU/FPGA. It looks like hashcat supports DES, which is also 56 bit.

Don't suppose anyone has seen in person one of the clones of the flipper zero that are on Aliexpress?

Heh, very fun :) I've not come across any locks yet thankfully, in it!

Are you sure it's cheaper than a glass hydrometer, you can get one for around £3

I'm working on 3D printing a lens mount and battery holder for Canon EF lenses to a night vision tube I've got ( https://github.com/anfractuosity/darkplace ). As well as been playing with creating plastic keys

I didn't think a single photosite was directly converted to a single pixel, there's quite a number of different demosaicing algorithms. Edit: Upon doing some more reading it sounds like a photosite or sensel, isn't a group of

Yeah, I'd not heard of that either, I recall postcardware though - https://en.wikipedia.org/wiki/Shareware#Postcardware

There's a Gameboy clone made by kongfeng that seems kind of like this, with its own chip. I'd love to know more about how they created it.
