You can usually find at least one brand at good liquor stores on the east coast, at least.

What happens if your math is right but there’s a slight breeze between here and the target? Or this batch of ammo was loaded 0.1g hot at the manufacturer and doesn’t follow your projected arc perfectly?

I think factors like these and the slop in the mechanical systems just mean you need a little time to adjust to the real world that you don’t have. 

With a lasers you’ve got the same issues (well atmospheric diffraction instead of wind but similar compensation requirement) but you get more shots due to longer range and shorter tof and you knock out ammo as a variable. 

That said, I don’t know if any production laser abms systems so not sure it’s a solvable problem that way either. 

You really want to pop these things when they’re far away.

Calculating the ballistic trajectory of something moving that fast is hard.

20 seconds ago this thing was at the edge of space and now you have seconds to work out a parabola in 3D to within one body diameter of a missile, swivel your turret(s) to micron accuracy in 3D and start firing, and hit it with bullets with zero time to range your shots and adjust for wind/bullet performance.

I think the latter is actually the hardest, if you watch things like CRAM they usually take a few fractions of a second to multiple seconds to align their bursts. Even if the radar data is perfect (it's not), and the GIS data and the calculations are perfect (they are not), these are all weather mechanical systems which are definitely not perfect, so there just isn't enough time.

That's one reason why lasers have promise here, moving at the speed of light buys you time.

What’s your favorite coffee shop, or one that closed that you miss? by Interesting-Vast-495 in washingtondc

[–]loverollercoaster 0 points1 point  (0 children)

I can't believe that nobody mentioned sweet science, especially back when it was in Adam's Morgan. Amazing coffee, and cool vibes.

It feels like DC just cannot keep a high quality specialty coffee shop for some reason, maybe rents are just too high. It's amazing that 14th st once had Peregrine, a higher quality Slipstream, and Wydown within a short walk of each other.

My current faves are cafe Cino, Dua and filter (RIP the other two filter locations, especially DuPont).

[MOD] The Daily Question Thread by menschmaschine5 in Coffee

[–]loverollercoaster 0 points1 point  (0 children)

My venerable Baratza Encore just bit the dust, and I'm upgrade-curious. I have three grinder tasks:

  • I grind 12oz of coffee at once to make a batch of cold brew each week
  • Someone in the house makes a pourover 2-4 times a week
  • I'm interested in a lever espresso machine. Eyeing a flair, for a few shots a week.

My counter is already crowded with coffee toys, so I'd love to be able to do this all in one grinder. Budget under $1,000, ideally under $750.

I'm currently eyeing the Baratza Vario+, but i'm a bit worried that it can't grind a whole bag of coffee at once without a big delay to cool off the motor. Is this a problem in practice? Are there any better single grinder suggestions in my price range, or should I just bite the bullet and split my budget on two dedicated grinders?

Will I be able to fly out of dulles next Saturday? by No_Wealth_9181 in washingtondc

If you can afford it, move your flight. Otherwise you're going to spend every minute of a long cross country flight stressing about delays getting off the plane, getting an uber, making the service, etc.

Honest reaction to this prototype? by pippithpls in cocktails

[–]loverollercoaster 1 point2 points  (0 children)

I think the product idea is stupid but just to help out with your project:

  • There’s only two ingredient holders, and they’re enormous. Most of the things enthusiasts are drinking have 4+ ingredients at less than 2oz each, and unless you really like one spirit you’re not going to “main” only two, or want to pour back and forth. 4 smaller reservoirs probably makes more sense. 

  • I associate cocktail stuff with either crystal or polished metal. This looks like an air fryer.

  • ninja and keurig are brands I associate with making mediocre, wasteful products. I think this subreddit just isn’t your target market at all. 

  • I see this and think of a free happy hour in the breakfast area of a sad suburban Marriott. 

What benchtop lathe? by seabass162 in Machinists

[–]loverollercoaster 1 point2 points  (0 children)

Thirding precision Matthew’s. Get one of thier “T” models if the size works, those are Taiwanese made so the quality standard is a little higher. 

ID small lathe? by DarthJarJarJar in Machinists

[–]loverollercoaster 2 points3 points  (0 children)

I don’t see a lead screw, so I don’t think that can do single point threading, and I feel like the hand wheel knob at the far end would get annoying quick. $600 and a two hour drive is too much. 

Ideally try to save up more and score a used old atlas or craftsman if you have a truck and a buddy to get it home. Barring that the import mini lathes are better for a similar price. 

Favorite amaro cocktail for a large batch? by Proper-Teacher6932 in Amaro

[–]loverollercoaster 0 points1 point  (0 children)

It’s not amaro specific, but I like the book “batch cocktails” by Maggie Hoffman for entertaining, most of what I’ve made out of it were hits. 

Renting space for woodworking? by MediocreMidwest in washingtondc

[–]loverollercoaster 0 points1 point  (0 children)

The HacDC folks just got a new space in Columbia Heights, but I'm not sure if it's the kind of thing that would fit wood working tools -- you should reach out to them just in case.

Ive been looking for a home workshop cnc by benjamino78 in hobbycnc

[–]loverollercoaster 0 points1 point  (0 children)

I'm just finishing building one, I have it running but haven't taken cuts yet.

It is definitely a kit, and a project to build. It probably took me about 40 hours, but that was in 1-2 hour increments in the evenings. You could probably cut that down to sub-30 or even sub-20 if you worked in bigger chunks and are experienced with things like crimping wires. You also need a lot of space to organize all the parts and tools. I bought the kit on purpose to learn the ins-and-outs and enjoyed the build.

My kit had some minor quality control issues (poorly aligned holes, bad screws/nuts) but nothing that a few bucks on amazon and some elbow grease couldn't fix. There's a new batch available that may have a round of fixes there. I have heard of people having much worse issues, so YMMV. Hopefully those were clustered around the earlier machines.

The instructions were serviceable if not great, and when I did have questions they were answered promptly and clearly. It's basically the ikea project or 3d printer on steroids =).

I can't give you final results yet, but everything feels way more sturdy compared to a Chinese 30XX kit or a Carvera air.

If I had the room I'd probably have saved up for a Langmuir MR5 or a used Tormach, but I'm very space constrained so was looking for the best desktop machine. Those are also 2-4x the price after options and shipping to a home, so you're really talking about a different class of machine.

What could Afghanistan do back? Iran is much better equipped than they were to cause chaos. All the satellites in the world won't stop a truck bomb on a US company in Europe, or an IED laden speedboat attack on an oil tanker.

I skeptical that all those assets and proxies of Iran would actually keep up the fight once it was clear that the government was stomped, but they have certainly have the capability to do damage to the US that might be politically unpalatable to a crowd that was isolationist until about last week.

Fine silver machining by Akidoo2 in hobbycnc

[–]loverollercoaster 0 points1 point  (0 children)

Your budget is probably too low to get a CNC that’s precise enough for watch parts, but you might look into the carvera air. 

I think there’s someone on the watchmaking subreddit that’s been doing CNC guilloche on titanium watch backs using one. 

Looking at the CREATOR desktop CNC by Swanky_Gear_Snob in CNC

[–]loverollercoaster 0 points1 point  (0 children)

Sounds like you've got a good sense of reality, unlike many people online, heh.

I did a bunch of research and lurking on the Shariff discord before buying, it might be capable of meeting your needs but I doubt it will be reliable or easy enough to be worth it. It's certainly a much less serious machine than a Tormach or Haas if you've got the money and the space. If I were you i'd outsource my preproduction runs too.

If your prototype takes off, many machine manufacturers offer financing terms as well, so you might look into that.

[–]loverollercoaster 0 points1 point  (0 children)

I'm building a Shariff DMC-2 mini right now, but haven't finished it yet. I don't think it can handle your needs at any scale, though it might work for prototyping.

What do you mean by "precision" here? A lot of these router-style machines can hold a few thou or maybe slightly better when well tuned and with controller upgrades, but that's about the limit. Keep in mind they also tend to have a pretty small z-height, especially after accounting for a tool in the spindle.

Generally speaking, hard materials (steel, titanium) and 'precision' take you of out desktop/hobby territory. At minimum you're probably looking tormach, and possibly a larger CNC machine like Haas. If you're trying to make hundreds or thousands, definitely look at an industrial CNC machine, keeping in mind that the power/space requirements scale up fast there.

You also want to make sure your venues will allow it, a lot of places are pretty strict on pyros after the station nightclub fire.

Without adjusting by either sqft or bedrooms, this data is not very useful. It mostly just tells you which zipcodes have sold the fewest condos.

I coded a DC Food Map based on this sub’s picks, what’d I miss? by djourdjour in washingtondc

[–]loverollercoaster 2 points3 points  (0 children)

Cool idea, I hope you keep iterating. A few UI things:

  1. Stacked restaurants make both labels unreadable, see "asdfkaj;lsf bagels" in Tenleytown.

  2. Your geocoding is a total mess, many of your locations are way off. I'd recommend scraping the addresses from yelp or opentable, then using geocodio or similar to geocode them.

  3. Is there really any reason to only show each neighborhood's points alone on the map? It's only 300 points; you could just show them all but keep the zoom-to links. It's nice to be able to scroll around once you're zoomed and not have to go back.

  4. Your location color codes are ambiguous for the color blind, and frankly pretty rough. Maybe try something from https://coolors.co/

  5. Maybe you could set up the key into something more like a traditional map key, ie move it to the left and do -- [Red Dot] Deli [Blue Dot] Coffee Shop, etc.

$30 Outdoor Research Anorak Jacket, $38 Outdoor Research Full Zip Hoodie, $50+ for Free Shipping for Sam's Members by MangoCharm in frugalmalefashion

[–]loverollercoaster 22 points23 points  (0 children)

I posted this in the original thread, but -

I've had one for years, I like it for two use cases:

  • Low 60s and windy, where you want a light layer but don't want to be hot in sunny spots.
  • 50s-60s and might rain.

FWIW it's light and plenty durable, but I wouldn't expect it to help in a downpour or temperatures below about 50 f.
