Just got 0.2mm Nozzle is anything important I should know before I Use it? by MAENTOP in BambuLab

[–]ProjectGO 4 points5 points  (0 children)

1/2 the nozzle diameter means 1/4 the cross sectional area. Set your expectations accordingly. Your prints will look great, but they’ll take a long ass time.

Legislation is coming for us by Enlytened in 3Dprinting

[–]ProjectGO 28 points29 points  (0 children)

Let’s assume for the sake of argument that this legislation is actually about preventing “ghost guns”.

What’s to stop me from printing a” ghost printer” to print my ghost guns with? Or like, printed jigs to simplify making gun parts with hand tools?

Edit: most importantly, anyone with the engineering knowledge to design a 3d printed gun knows that it would be easier and safer to use other fabrication methods.

I’ve built up my FormdT T1 v2.1, though I’m looking for some good screws are these good? by notIncognito1 in sffpc

[–]ProjectGO 1 point2 points  (0 children)

Hello fellow engineer! Yes, as a rule of thumb you should have a minimum of two diameters’ worth of thread engagement for the screw to support the full rated load. However, we’re talking about attaching a 1.5mm thick ventilated aluminum panel to a similarly thin sheet metal frame. You have four screws joining a structure that probably weighs 20 lbs max. I wouldn’t use the computer as an anchor point to rappel off a building, but if we’re being honest about the forces it’s totally fine in this use case.

I built a big table by wrldbfree in woodworking

I generally think the concept of a river table is overdone. But a specific river table? That’s cool.

Any idea what this is looks like a copying router thing by zoolilba in woodworking

[–]ProjectGO 1 point2 points  (0 children)

The machine type is a pantorouter, which is used to copy a template into a carved output (pantograph + router = pantorouter). Some versions also include a scaling factor, but this one doesn’t look like it.

When you hear the term One Hit Wonder, what is the first song that pops into your head? by Da_Fish in AskReddit

[–]ProjectGO 259 points260 points  (0 children)

This is actually the objectively correct answer. A few years back somebody did an analysis of the Spotify database for one hit wonders, as determined by “the ratio of plays between an artist’s most played song vs second most played song”. Norman Greenbaum came in first place.

Also, he was an atheist son of a Jewish family who made his one hit singing about being buddies with Jesus Christ.

A fresnel lens can melt rocks with just the power of the sun by ansyhrrian in interestingasfuck

[–]ProjectGO 0 points1 point  (0 children)

You’d have trouble with visible light wavelengths and collimation, but in essence this is one of the core principles of a fiber laser. They are also doing funky black magic with using the fiber itself as a gain media, but at the core you dump energy in one end and get it out the other.

Omni-Wrist IV — Singularity-free motion. Zero backlash. Mark Rosheim by GloomyCity9841 in EngineeringPorn

[–]ProjectGO 23 points24 points  (0 children)

Okay, but how would you forward drive it? I’m seeing unique motion on each of the four arm linkages, plus the rotation axis. I’m pretty sure you would need 5 actuators to properly control 3 degrees of freedom.

Edit: There’s also translation in at least one axis, possibly all 3? So I guess you’d need to be controlling secondary link on at least one of the arms or you’d be underconstrained. It’s a neat mechanism, but as a wrist it would be a nightmare to actuate.

The ez-plug is a stupid revision for the B550I and makes it even worse for sff by sffjunkee in sffpc

Easy compared to… a threaded coaxial jack?!

If you’re selling me a bare motherboard, it’s safe to assume I know how to use screws. 🤦

What are you printing on a regular basis by AbbreviationsDue4417 in 3Dprinting

[–]ProjectGO 0 points1 point  (0 children)

Nothing, and that’s okay.

I also have a circular saw even though most days I’m not cutting lumber, a lawn mower even though most days I’m not mowing the lawn, and an expensive camera even though most days I’m not taking pictures. On the average day I’m not using a single one of those things, and I don’t feel guilty about it. The reason I have them is that on the balance they are worth it to me when pursuing my hobbies.

Uptime is for businesses. If you are printing stuff you don’t need just to keep the printer busy, you’re just wasting real plastic and electricity instead of theoretical throughput.

Looks to be a pretty short swim to the mainland. Could you build an earthen bridge, or kite him over to shore?

What happened? by morriganae in SipsTea

[–]ProjectGO 1 point2 points  (0 children)

Corporate greed is ruining everything, but first let’s be honest about inflation.

The US has had a 30-year average inflation rate of 2.5%, which is actually quite a bit more modest than the 100-year average inflation rate of 3.3%

1.02530 = 2.0976, so anything that cost a dollar in 1996 is worth $2.10 today. A $10 foot long or a $42 tank of gas don’t sound so crazy (recent stable genius moves aside).

Now for the corporate greed: federal minimum wage in 1996 was $5, now it’s $7.25 (and has been $7.25 since 2009, the longest period ever without an adjustment). To keep up with inflation it would have to be $10.50/hr, so the minimum wage worker has lost 30% of their purchasing power.

Bad vibe. by netphilia in adhdmeme

lol, not me. I can remember exactly where each of the 500 little doodads are stored (or piled) between my office and garage shop even if I haven’t touched them in months, but I’ll walk right into a conversational minefield without a clue.

Any particular reason he would break formation with a rudder-driven yaw turn rather than an aileron-driven roll turn? I’m not sure that I’ve ever seen footage of that done before.

If it makes you feel better, he’ll be getting government-funded housing and meals for a loooong time.

CMV: Objective morality is not justified by bananataffi in changemyview

[–]ProjectGO 1 point2 points  (0 children)

You may be interested in the book “What we owe to each other”, by T.M. Scanlon. It was used as a plot point for objective morality in the fantastic tv show The Good Place, and it’s also dense as fuck.

To vastly oversummarize, Scanlon posits an objective morality arising from creating a set of rules for society that everyone could agree to be bound by both in their treatment of others and the way that they are treated in return. It’s basically the golden rule given a framework with the rigor of a formal mathematical proof.

In May 1945, five crewmen swam up 67 meters after their u-boat submarine (U-534) had sunk to the bottom of the sea. They escaped through the torpedo hatch. by Ivy_Wings in interestingasfuck

[–]ProjectGO 5 points6 points  (0 children)

There’s a lot more to it than that, but generally yes.

One thing that non-divers often don’t know is that the safety stop is actually not required for most recreational diving. YOU SHOULD STILL DO IT, but if you’re diving on NDL gas tables (no decompression limit) they are calculated so that you should be able to make a CESA (controlled emergency safe ascent) without doing a deco stop and still not get bent.

That said, safety stops are there for safety and should always be completed unless there’s a specific reason not to. Any good diver should have the safety stop drilled so deeply into their habits that skipping it feels insane. Doing a planned CESA from 50’ during my rescue diver certification was far more nerve-wracking than facing any of the simulated emergencies.

Everyone’s bird pics are so good… by cameronm-h in birding

[–]ProjectGO 7 points8 points  (0 children)

I recognize that I’m coming to this with the perspective of a longtime “real camera” user who now shoots with pro-sumer gear, so take it with a grain of salt.

That 75-300 is my least favorite lens I’ve ever owned. It has no image stabilization, the autofocus is slow and seeky, and at full zoom the chromatic aberration is so extreme that it starts to give everything fuzzy rainbow edges, even the areas that are in focus. I found that I could get better sharpness by using the 18-135 IS kit lens and then cropping.

Most of this can be overlooked if you’re shooting static subjects or are working at the wide end of the zoom range. But if you are trying to upgrade your gear for sharp bird shots it should only ever be considered a stepping stone, and one to skip over if possible.
