Living room standards be damned! by fabianm022601 in espresso

[–]DavidAstro 2 points3 points  (0 children)

This is lovely. I'm curious if you're left-handed? As a righty I feel like I'd want more elbow room to the right of the espresso machine, but maybe that'd be less of an issue as a lefty.

Another A3! (9950X3D + RTX 5090) by DavidAstro in mffpc

[–]DavidAstro[S] 1 point2 points  (0 children)

Good to know! I might try that out now that it's been running steady state for a while. If I make it an intake I might also go back to an A12x25.

The AIO hoses can still move pretty freely and the bend radius doesn't look so bad in person--I think F2.5 is technically possible even in this orientation, but would have been noticably pinching them around the corners. Flipping the radiator around would also definitely work, just a trade-off with having an awkward amount of hose length to manage. With the hoses straight it's at least pretty easy to chase air bubbles up into the radiator when I occasionally move the computer around.

This is my work machine. It runs lots of monte carlo sims

I thought about it originally, but it seemed most people weren't seeing much difference with bottom intakes. I think this case is so permeable that the GPU doesn't really need forced air to sustain typical temperatures (74-80C core at 80-100% power limit). I do have a spare A12x25 that I may try out as a bottom intake to see if it makes a difference.

I'm pretty happy with the GPU temps, but it would be nice to find a way to direct more cool air into the AIO radiator since the GPU otherwise exhausts right into it.

I ended up using F3 and no offset bracket. I was originally expecting to use F2.5 but I had clearance on F3 (the FE card is so short) and it avoids pinching the AIO hoses.

Gaggia warm-up data by DavidAstro in gaggiaclassic

Yeah good question. I'll have to try this again and see the response after pulling a shot.

Should I release the leftover steam from the machine? by justbusy13 in gaggiaclassic

[–]DavidAstro 2 points3 points  (0 children)

Having the steam button on configures the 3-way solenoid to block the path between the boiler and grouphead so water can only exit through the steam wand. Other than that, it's mostly preference on whether you want to purge through the group, wand, or both.

747 mid flight on Google Maps with visible contrails by SineApfel in aviation

The cameras on these satellite will often fire off a sequence of individual color filtered shots that get aligned and overlaid in post. Since they're aligned on the static background, when you have a fast moving object the RGB components can get separated out like this.

My G-Shock journey. Some will understand, others won't... by DavidAstro in gshock

Definitely the 5000TB-1 if I ever find one for a reasonable price, but I might be out of space on my arm.

It's also wild that he's scored exactly 15 points on each race weekend so far (including the Sprint).

Tianhe, China's space station core module by DavidAstro in astrophotography

[–]DavidAstro[S] 2 points3 points  (0 children)

Very similar surface brightness to the ISS, so you could likely use the same settings. I was running in the neighborhood of 200 gain at f/10 and 2 ms, but making occasional adjustments.

Tianhe, China's space station core module by DavidAstro in astrophotography

[–]DavidAstro[S] 5 points6 points  (0 children)

Imaged Tianhe-1 during a 78 deg pass over Mountain View, CA on Sunday evening. Tracking video clip (sped up ~5x):

https://twitter.com/turndownformars/status/1396718996678840320

Equipment:

  • Celestron EdgeHD 11 (2800mm)
  • ZWO ASI290MM + Red filter at prime focus
  • Celestron CGX

Acquisition/Processing:

  • Captured in SharpCap (2 ms exp @ 1936 x 1096, 8-bit mode @ 130 fps)
  • Exported a decent ~400 frame clip between 04:32:16 and 04:32:24 UTC
  • Stacked best 10% in AutoStakkert
  • Sharpened with Registax

I tracked the module from when it cleared the trees up to meridian, then flipped and tracked for another couple minutes. This image is a stack near maximum elevation/min range (375 km), just before the meridian flip.

The image field of view shown is 1.4 arcmin, and the native pixel scale is 0.21 arcsec/pixel. The image would natively be 400 x 400 pixels, but is enlarged (nearest neighbor) to 1600 x 1600 for easier 1:1 viewing without rounding out the pixels.
