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.

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:

It was getting later and chillier in the day when I found this busy bee taking a rest.

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 :)

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.
