Why in the world would a TV have a blue only mode?

I haven’t seen this pattern in a long time! Reminds me of that opener from Neuromancer https://scifi.stackexchange.com/questions/163304/what-color-was-the-sky-above-the-port-in-neuromancer#163310

So I’m currently traveling and I made a little blog for my friends and family complete with a little map libre gl globe and icon of me that moves around. I’ve got it behind caddy/authelia so to access it you have to have credentials. However I would quite like it […]

Here’s a schematic view of the human eye called the Gullstrand schematic human eye. Fun fact: I have intraocular lense implants so my own eyes actually have two extra surfaces compared to this diagram.

This graph is great, in the text they point out that the range of intensity levels where human eyes work is about 10 orders of magnitude. However photoreceptors themselves only cover about 5 orders of magnitude. To make up the difference we have our iris that […]

TIL: Box jellyfish larvae have eyes but no brain to connect them to so instead the eyes also swim a bit. Source: Animal Eyes, Land & Nilsson, second edition, chapter 1

I really like how capacitors and inductors are mathematically kinda mirror images of other another. One smooths out voltages and one smooths out currents. One has equation V=LdI/dt and the other I = C dV/dt.

Here's that summed up in a little table where I've also […]

Cycling in to work today I picked up this completely broken phone holder that had obviously fallen off of a motorcycle. Turns out it has a little wireless charging module in it! Googling the IC numbers it it accepts up to 36v input (only tested it to 24v, just in […]

Teeheee 😆 pygame is quite fun for just blasting something simple to a frame buffer.

Got a second hand kobo e-reader, it’s my first proper experience with e-paper and it is _really lovely_. I downloaded calibre and loaded some blogs onto it, the html -> epub conversion seems subject the to the vagaries of how each site is formatted but of course […]

TIL that you can just connect many displays directly up to an RPI, twiddle some device overlays, and it will show up as a framebuffer in the system.

Might use this to make a slightly ridiculous viewfinder for the microscope, or slightly more useful, to see when […]

Ok I used astropy to convert a bunch of locations on earth into a cartesian version of the Geocentric Celestial Reference System. Locations on earth spin around this system over time but at least the axis of rotation seems to be the Z axis and the north and south […]

That's the diagram for geodetic coordinates from Wikipedia. The fact that the point C isn't the centre feels so deeply cursed to me. I really think we should do something about the earth not being spherical, it's just not ok.

Hackney seems to be approximately on the surface of the WGS84 earth, which is encouraging.
July 19, 2025 at 12:51 PM
Ok so I can get a location on earth in astropy and I can convert it to lat,lon,height (presumably this is WGS84 but the neither the docs for to_geodetic nor the object) I can also get it as a (x,y,z) coord using `to_geocentric`. There's no time here so this second […]

And finally a bed visualiser to see when it's time to fiddle with the screws again instead of just relying on the autoleveling.

Next up is slicer thumbnails. If you set your slicer up to embed thumbnails into the gcode then you get nice little thumbnails in your file viewer. Since I never give good names to my gcode files, they're always called something like "part_1_2h13m....gcode" the […]
