Or random application availability and/or ease of use.

Two cases in point:

  • Photo Mechanic. It makes it really easy/fast to sort through tons of photos. There are some Linux compatible alternatives, but they're just not as good
  • Fusion 360. There are a couple of things you can do to make it work, but since Linux isn't officially supported the install process can be a bit fiddily and there's no guarantee that an update won't break things.

Things are certainly better now than they have been in the past, but if you're somewhat time limited (eg your computer is more of a tool than a thing to spend time tweaking) Linux can still be a bit offputting - especially if some of the core applications you use aren't officially supported.

First, nice photo! Even "old" gear can take great photos. Throw motion and/or low light (with a fast lens) into the mix and you'll beat a modern smartphone.

The quick lead into the exposure triangle is:

  • ISO is basically "gain" applied to the photons that hit the sensor. Some gain = fine. More gain = you start to run into signal to noise ratio challenges
  • shutter speed helps you freeze the action, or can also let the action blur on purpose. Examples of intentional blur include panning photos (think auto racing) and long exposures (at night or during the day with the aid of a ND filter)
  • aperture. This is the ratio of focal length to lens aperture. Keep in mind it's 1/x, so as x grows the actual aperture is getting "stopped down" (aka closed/smaller). Wider aperture (aka small denominator) = less depth of field and more light will hit the sensor. Stopping down = more depth of field and generally more sharpness/less vignetting, but if you take this too far you'll hit diffraction and lose sharpness

You wind up trading values against each other in various scenarios, which is why it's called the exposure triangle. It's very much a "you pick two and deal with the third" situation. Which two you prioritize really comes down to what you're trying to accomplish.

For your barn photo's exposures, let's talk tradeoffs. It sounds like you know that your ISO value was too high, especially for a static subject and good light. So how to get it to go down? You could do a mix of:

  • using a slower shutter speed. Unless you have a tremor, the rule of thumb is minimum shutter speed should be more than 1/focal length. You could have easily shot this at 1/100, if not lower. That would cut ISO down to around 1600
  • open your aperture. f/14 is very closed and likely isn't needed unless you really want to see something deep in the background/foreground. You're also likely losing some sharpness due to diffraction

Happy shooting! Feel free to ask follow ups.

Looks nice! Details on that green house? I would really like to jump start my season here if I can...

[-] IMALlama@lemmy.world 4 points 4 days ago

Very cool. Was this a test piece or do you intend to do CNC carving like this in the future? What finish do you think you'll use? Any surface prep ahead of time like sanding? Details on the CNC?

So many questions!

You're four forks deep now Slic3r to Prusa Slicer to Bamboo's slicer to Orca. It also borrowed a lot of ideas from Super Slicer. Since it's open source, and has been gaining some momentum, it seems to have a decent amount of contributors

Why Orca?

  • all the features you know and love from things up the tree
  • a revamped UI
  • built in tuning tests (temp tower, extrusion multiplier, volumetric flow, pressure advance, etc)
  • great Klipper integration if that's your jam

I hope you're back to your normal physical self soon.

As far as the 3D printer goes, there are three main types of categories of people with printers at home:

  • Tinkering with the printer is the hobby. This can be a mix of tuning for better quality, faster prints, etc as well as physical modifications to the printer. One of the extremes of this is the speedboat race where people go all out for the fastest print of a common model
  • Modeling things and then printing them. I fall largely into this camp. I've made many a replacement part for a kids toy, jigs/fixtures, brackets, printer mods, speakers, wagon wheels, a thing to keep cats out of potted plants, even a tiny toolbox for the minimal amount of tools I used to carry at work
  • The printer is largely an ends to printing free/paid designs from the Internet. There are tons of designs out there that are a mix of cute (but probably throw away), functional/practical, things you could sell, etc

If you're modeling it will be mouse and keyboard, but a SpaceMouse will improve ergonomics. All you're really using the keyboard for is number input.

If you find yourself in the functional print crew, don't be surprised if you wind up printing things to help in your garden. Some of the PVC fittings holding together my arch are now printed parts (less effort to model and print a replacement than drive to the store) and the hooks the "gates" to my fence hang on are also printed. Once you get in the habit of finding things you can print you'll be finding them everywhere.

It's all tradeoffs. I've been too busy with mulching to cover my squash vines and it's vine boarer season here :( it's on the list for this weekend.

When I planned these beds I spaced them far enough apart to get my lawn tractor in-between them, but getting between them and the fence involved my weed whacker. As anyone with a fence has found out, maintaining the grass at the base of a fence is a pain.

I'm 3/4 of the way done with the edging. It's 10" tall with something like 6" or 7" of it buried. It does a good job of keeping grass out of our other beds, so I'm sure it will do a good job here. The downside is the most effective way of installing it is to trench first, put the edging in, and then refill the trench. If you try to use one of those big pizza peel looking things to make a narrow slide the will usually get wavy due to variation in trench depth.

I mowed to basically ground height between the beds, weed whacked around the beds, and put in a layer of that thick paper builders will use to protect flooring below the mulch. Some areas for cardboard instead, but we just didn't have enough cardboard to cover it all. Hopefully it will be enough to kill the grass and hopefully that results in less grass appearing in my raised beds.

We too have lilies (lemmy.world)

Topped by deer and it looks like Lily beetles are a thing here now :(

I got tired of remaking my sisal trellice every season, and didn't like using nylon netting, so I went with something more long term. The downside? Vine removal in the fall will likely be a slog.

No banana for scale, but let's say that it's not too big and not too small. The dimensions are 295mm tall, 270mm wide, and 240mm deep. If I had to do it again, I would be tempted to go a bit wider and touch less deep. It's probably better to be large in one of these dimensions as opposed to both of them.

Here's the top. It has a jack for charging, a connector to program the DSP, a switch to turn it on and off, and a battery gauge.

The speaker also has a built in handle that's way chunkier than it appears, but is still particle.

The big BOM pieces are a Dayton Audio LBB-5Sv2 for the BMS (battery management system), a Dayton Audio KABD-250 2 x 50W for DPS, amplification, and Bluetooth, a Peerless by Tymphany BC25SC08 tweeter, and an Italian-but-made-in-India woofer (a Coral PRF 165).

The print itself is three pieces: the bottom bit (black), the middle bit (white, blue, and white again thanks to not having enough white left to do it all in white), and the black top. Here's a CAD view that more clearly shows the three pieces:

the three pieces are held together with heat-sets and m3 bolts. There's also a tong and groove like joint to help the enclosure leak less air. I haven't noticed any evidence of air leaks while listening.

The amplifier and battery board mount to the bottom like so:

The middle was printed with some supports for the driver overhangs, but the ports and everything else were designed to print in place without supports.

This is certainly not meant to be audiophile build, but it's surprisingly decent. This isn't my first blue-tooth speaker, or even my first printed loudspeaker enclosure, but it is the first that was somewhat intentionally designed to have OK bass response while also being reasonably compact.

It measures fairly well. Frequency response, along with harmonic distortion, is pretty good. There's zero windowing or smoothing on this plot. I suspect the distortion spikes at 1 kHz, 2 kHz, etc are induced by the Bluetooth stack the board is running since they've shown up in multiple different enclosures and with multiple different drivers.

There's no nasty ringing, caused by either the drivers or the enclosure, so life is pretty good:

I'm guessing this is the result of layers of slathering a fresh layer of finish on these tables. To be honest, I kind of like the look. Any idea what type of finish this might be?

Here's a slightly different angle:

Our kids wish we had more. I'm not sure which verity these are, but they put out tons of runners which makes me not want to put them directly in soil.

Tips for a bigger crop are welcome :)

standing desk legs (lemmy.world)
submitted 1 month ago* (last edited 1 month ago) by IMALlama@lemmy.world to c/recommendations@lemmy.world

Title basically. I have a decently large solid wood desktop (guessing around 72"x30"x1") that supports two computer monitors, two studio monitors, a tower computer hanging under it, a laptop on it, and a decent amount of clutter because it's a decently sized space I spend a lot of time sitting in front of. I'm currently using Ikea IDÅSEN legs (they were a lot cheaper in early covid) and they're stable, but man are they slow to go up. They have no problem going down though, lol.

It would be nice to have an equally solid pair of legs stability wise that go up faster with some weight on them. Any suggestions?

Thanks!

At least so far. The first go round had the nozzle crash into the tree support, resulting in a layer shift. The good news is that the print stayed very firmly stuck to the bed.

I've reset, lowered my extrusion multiplier a smidge, switched to a more traditional support pattern, and am going for it again. Wish me luck!

Both pots were started at the same time from the same batch of strawberry starts. They should have the same soil box. Both grew vigorously last spring/summer and got visited by deer in the fall. Both bounced back pretty well before winter set in. The left pot is very happy, the right... Not so much. I do recall the big pot having quite a bit of wilted leaf cover all winter, but don't think that was the case for the pot on the right. Maybe I didn't notice a late in the season deer visit that set the small pot back? Maybe the smaller pot got just enough colder than the big pot to kill some roots? Any other theories?

I think I'm going to lean into the FF E-mount world, which means giving up my D5300 + Nikon AF-S 70-300mm f/4.5-5.6 VR (115 - 450 FF equivalent). Before kids, I used this lens for motorsports/landscape/travel. Post kids we don't do a ton of that, so I've been getting along well with a pair of 35mm and 50mm primes.

My kids are pretty young and are starting to play outdoor sports like T-ball and soccer. This has brought my D5300 + 70-300 out of retirement. I'm missing the conviences of my A9, so I'm trying to figure out what lens I should get for sports duty. At this point, everything is outdoors during the middle of the day so there's no need for a fast lens. It was pretty drizzly last weekend and my current (slow lens) setup still kept ISO below 1k most of the day with a 1/640 shutter. I figure I can comfortably double ISO and halve my shutter speed on the A9 while still getting a lower noise image than I have today, so I don't think I need fast glass.

Looking through EXIF data from the previous few games on the D5300 + 70-300 it looks like I use the full range of focal lengths, but the vast majority of shots are under 400mm FF EQ and above 150mm FF EQ. I'm a little wary of wanting more reach in a few years when the kids are on bigger fields, but they'll also be bigger so maybe it will wash out. Who knows if they'll still be interested in playing either.

So what do you think?

  • Third part lens that stops at 400? This means no teleconvertor in the future, but this seems like it would work well for today
  • First party 100-400? Adding a 1.4 teleconvertor makes this a 140-560, but it also makes the f-stop at the long end f/8 which might not be great for sports
  • 500mm? Tamron's 150-500 seems decent and doesn't call too much attention to itself, but it is heavier
  • 600mm? These lenses are all fairly bit/shouty visually, but are potentially more future proof....

This is a follow up from my spaghetti post a few days ago.

Good news: I caught the nozzle catching on the infill during travels. The infill must have been curling up ever so slightly. Turning z-hop on solved this. I also bumped my nozzle to 255 based on a temp tower, but I don't think my original issue was flow related.

Bad news: this brought me to the failure above - evidently my chamber temps are too low for this size of ASA part and it warped. Maybe the higher nozzle temp contributed. Maybe this size of ASA part is unrealistic despite not having sharp corners. Maybe it's the fact that it's continuous from side to side. I am still going to attempt to print a hollow cylinder to go between this piece and another similar piece in ASA, so I guess we'll find out!

Good news: the part did not let go of the build plate. I'm pretty happy about this. My first layer is not overly squished, I've never used any adhesion aids (glue stick, hair spray, ASA slurry, etc), etc. Tuning my print_start sequence is resulting in a very consistent first layer.

Bad news: the build plate came up with the print. Holding the build plate down with binder clips or the like would probably just make something else fail.

Good news: I had enough PETG in stock to use that instead. Zero warpage, so great success. I had to go a bit slower because a flow test showed that I'm limited to around 25 mm^3 for PETG before the extrude motor started misstepping, despite bumping temp to 255 °C. I limited flow to 20 mm^3 to be safe. The print's a success so meh.

Yup:

The boy, identified only as Landen, was 5 when Emmanuel Aranda threw him nearly 40 feet to the ground. Aranda, who had been banned from the Bloomington, Minnesota, mall twice in previous years, told investigators that when went there “looking for someone to kill” after women rejected his advances.

The guy sounds like a real winner.

Until your home instance defederates from another instance. Sure, you can always make another account, but your average user wants a lower friction experience.

I'm reasonably active in the fediverse, but I recognize that the more explaining it takes to the average user the less likely they're going to want to join in.

The old old top gear cool wall tried to hit on this concept. You could have a very technically excellent car classified as uncool because if you had to explain why it was cool to a normie you had already lost them.

It will be hard for the fediverse to get over this hump, which is probably why you see so many Linux users here and so few say woodworkers or other (somewhat) more niche communities.
