So, I want to engrave some things. Most of these things are going to be iron, steel, or aluminum tools, but I'd also like to engrave some less durable items, such as plastics. I've done a couple searches, and I'm looking at engravers ranging from about $80 (US$) all the way up to about $180,000. I suppose that if I searched, I could find some cheaper, and almost certainly more expensive.

So, I'm looking - and all that I can really see, is how ignorant I am. I have almost zero idea what it is that will make a long-lasting engraver. Will one of those ultra-cheap engravers from China last for ten years of light-to-moderate use? Probably not - but what do I know? Is it necessary to spend thousands of dollars for the same thing? Newegg has a variety of engravers, for less than $400, but the biggest, most powerful among them has a disclaimer:

Engraving Material Note:
1.can engraving materials:wood,bamboo,plastic,paper,leather,bank card,rubber
2.can not engraving material:metal,stone,ceramic,shell,light-reflecting material,transparent material

Seems pretty obvious that I need something bigger, and more expensive, than a $400 engraver. Can engraving metal, dammit!

Does anyone here have experience with non-industrial laser engravers? (Industrial? Quarter million dollars entry level?) Power ratings, sizes, brands, whatever - any information is welcome!

NASA to Discuss Upcoming Launch of Next Planet Hunter

Join NASA at 1 p.m. EDT Wednesday, March 28, as astrophysics experts discuss the upcoming launch of NASA’s next planet hunter, the Transiting Exoplanet Survey Satellite (TESS). Reporters can attend the event in person at the James Webb Auditorium at NASA Headquarters in Washington or participate by phone.

The briefing will be broadcast live on NASA Television and the agency’s website.

Scheduled to launch April 16, TESS is expected to find thousands of planets outside our solar system, known as exoplanets, orbiting the nearest and brightest stars in our cosmic neighborhood. Powerful telescopes like NASA’s upcoming James Webb Space Telescope can then further study these exoplanets to search for important characteristics, like their atmospheric composition and whether they could support life.

This is a follow-up to your previous request #389648 "Very Loud, Very High-Pitched Tone From L3+"

The loud, high-pitched tone was an over-current alarm from my UPS.

Its voltage/current label rated its power output at 750 Watts. The L3+'s printed instructions report the combination of L3+ and APW++ use 1000 Watts. I had some other devices plugged into it, so the total power consumption was way over the limit.

I rearranged my power cords, and am now blessed with a happy home that has no loud, high-pitched tones driving me totally bananas.

Thank you for your prompt, courteous and helpful support.

You may close this ticket.

PS. I'm going to order another L3+ soon - my second.

================

I really find my UPS' behavior puzzling: I was way over the rated power 24/7 yet my Coinfoundry stats as well as my rig's embedded website both reported that my unit was working just fine.

John Oliver’s Gay-Bunny Book Is Outselling the Mike Pence Book It’s Trolling

Worst Pence bashing since Trump:

“Trump thinks Pence is great,” Bannon told me. But, according to a longtime associate, Trump also likes to “let Pence know who’s boss.” A staff member from Trump’s campaign recalls him mocking Pence’s religiosity. He said that, when people met with Trump after stopping by Pence’s office, Trump would ask them, “Did Mike make you pray?” Two sources also recalled Trump needling Pence about his views on abortion and homosexuality. During a meeting with a legal scholar, Trump belittled Pence’s determination to overturn Roe v. Wade. The legal scholar had said that, if the Supreme Court did so, many states would likely legalize abortion on their own. “You see?” Trump asked Pence. “You’ve wasted all this time and energy on it, and it’s not going to end abortion anyway.” When the conversation turned to gay rights, Trump motioned toward Pence and joked, “Don’t ask that guy—he wants to hang them all!”

The electricity costs too much: $299 for each 15 Amp circuit breaker. So maybe I don't get to quit my job for crypto.

I'll keep looking around, perhaps the juice would be cheaper if I used a whole rack, or if it were in a less-convenient place than Portland.

Some of you Soylentils colocate your servers - have you any suggestions?

I expect to buy a used car when I get paid. But I'll need a colo that's close enough to Vancouver Washington that I can reasonably driver there, and not have to fly.

There are three power socket circuit breakers in my apartment. I'll buy at least one more Antminer L3+ litecoin rig.

That's all, folks.

Isn't that what the government types keep saying?

So why is it that the head of that self-same government doesn't play by those rules? Does he think the law doesn't apply to him?

In my mind, those who are privileged to represent us should be *more* forthcoming and avoid even the hint of any conflicts of interest, illegality or lack of transparency.

Why then does our current administration fear the Mueller investigation? Let's get to the truth and let the chips fall where they may.

Which is why it seems odd that our 'fearless' leader is acting like a frightened animal:

A lawyer for President Trump called on the Justice Department on Saturday to end the special counsel investigation into ties between Russia and the Trump campaign, shifting abruptly to a more adversarial stance as the inquiry appeared to be intensifying.
[...]
Mr. Dowd said at first that he was speaking on behalf of the president but later backed off that assertion. He did not elaborate on why he was calling for the end of the investigation, saying only: “Just end it on the merits in light of recent revelations.”

People close to the president were skeptical that Mr. Dowd was acting on his own. Mr. Trump has a history of using advisers to publicly test a message, giving him some distance from it. And Mr. Dowd’s comments came at a time when members of Mr. Trump’s legal team are jockeying to stay in his favor.

Hours later, the president echoed Mr. Dowd’s accusations of corruption in the theoretical “deep state” that Mr. Trump has long cast as a boogeyman working to undermine him.

”There was tremendous leaking, lying and corruption at the highest levels of the FBI, Justice & State,” he wrote on Twitter.

In the end, the truth will out. Let's hear it. Whether it's that there was no collusion with the Russians or if there was. That's actually less important than making sure we have the facts.

However I have not yet decided on the value of $LARGE. That will be determined by how many LiteCoin mining rigs I can operate without having to hire any help.

Most likely "LARGE=One_Cabinet".

Opus Interactive quoted me $299 per month for 12U in their Portland data center. I think that's big enough for 12 Antminers and 12 power supplied.

However that quote was for just 15 Amps at 110 Volts. With their power supply, one Antminer L3+ mining rig with one APW++ power supply consumes 1000 Watts so I just now requested a quote for lots more power.

I do understand that means they will charge me for lots more cooling. My present living situation limits me to three rigs.

I presently estimate that I would break even with three rigs, but I haven't gotten their power quote yet.

I've been puzzling over whether I should buy a car with my next paycheck. To have a car would make my life quite a lot easier but to spend all that money would mean that I can't go as long without a client.

But were I to colocate anything in Opus' data center it would be a huge Pain In The Ass to take all my gear on the bus.

I'm also wondering whether that would work were I to use taxis.

"What do you see?" asked the psychiatrist.

"There are worms coming out of your face."
