My ender 3 pro printer died Thursday,as it happens I have a major savings program as part of my finances specifically for me so I was able to buy a
ELEGOO Centauri Carbon 3D Printer for $350.72.

as much as I like the old printer it was destroyed I think a fan in the print head died, resulting in a massive meltdown of anything plastic in the print head. As I understand it they have a new head that has nothing but metal parts in it that this should not be a problem in the future, however this new printer is so superior among other things you can do is ABS plastic.

It can also do multi color spools which I decided not to get, also on the advice of my friend.

This printer comes with a built in Wi-Fi interface which I can access directly with a IP address or use my Orca slicer to control directly.

How smooth can you get the walls of say a simple box say 2x4 inches by 1 inch high?

 

This printer has a footprint to 10 inches by 10 inches by 10 inches. It is accurate to a much greater degree than I have ever seen before I have made a sleeve you know for another box that was able to mesh at 0.01”. It is tight but it fit. I hide A hershey's kiss inside for kids and what not.

 

Double Doh! slap. I've completed a new project. I burned up 5 voltage regulators due to I was using the wrong pin out sheet.I also added several weeks to this project due to using PNP transistors that I knew were NPNs, I paint the tops of PNPs red so I knew these had to be NPNs, I finally used my phone camera x2 picture to figure out I was being an ID10T. Life goes much easier with good eyesight.

We did the same thing long ago in production environment. The pinout for a negative regulator was different than for a positive regulator. Blew out several chips before it was discovered.
"Why doesn't this dang thing work, we have all the pins right!" ha ha

INDEED! The pinoutsfor negative regulators are probably so very different BECAUSE when the polarity supplied to a negative regulator is reversed, it tends to go into a "shorted circuit mode", which connects what would be the input pin of a positive regulator fairly directly to what would be the output pin of a positive regulator. THAT could very easily destroy all of the sensitive downstream stuff that was supposed to get 5 volts instead of 22 volts.
AT LEAST, that is my understanding of why it was done WAY BACK at the beginning, many decades ago.
I do not recall the name of the sales rep who explained that to meback in about 1976, I think it was. Nor the name of the electronic sales organization he worked for.

I don't remember much more about this it was way back in the 1980's maybe early 80's. That's a long time ago.
It's funny it passed through several hands before it got to production yet it still got reversed. I have a feeling it was one of those:
"Since it is just lighting up a light bulb it must be so simple we don't have to check it too thoroughly"
moments. It's so simple it is unthinkable it might be wrong so just pass it along

 

I like @MisterBill2’s explanation. I always thought it was sloppy engineering, but I can now see the logic of it being intentional.

 

I think the designers of the 78xx and 79xx series wanted to keep relative functions of the pinouts the same. By which I mean that if you consider Pin 1 is always the most Positive pin, Pin 2 and the Tab is always the most Negative, and Pin 3 is always the Output (somewhere in between), you can't go far wrong!

 

So I went through a major depression jag, mainly because I was unable to reach my daughter, who is actually my youngest niece. She finally called me back and we had a nice talk. She was in a situation where she couldn't call. Now I can reach her on a regular basis, which really, really helps. I'm glad because my printer just died. I've ordered another one, the multicolor Centauri carbon Egeloo.

I publish projects, partly to give me something to do to keep myself sane. Not sure how sane I am, but so far it seems to be working. I'm mostly trying to keep the dark thoughts at bay.

I remain active in a few electrical/electronic forums and a uC forum just to try and keep abreast of things. Going on 14 years since I surrendered my credentials and walked out of the plant and into retirement. Rumor Control says if you don't exercise your brain it turns to oatmeal as we age.

First time I have heard of a daughter also being a niece. We forget that not all family relations are through bloodlines in the usual way.
All we have to do is adopt somebody and they become our son/daughter, even if they were also something else to begin with.
I think there are also special legal interpretations too that can skew the normal relationships.

With that in mind, I think I will adopt myself so I become my own son, and then I can claim another dependent at tax time (ha ha).
Once I become my own son, I can then adopt my father, which gives me still yet another dependent (and then I will also be my own father).
Etc., etc., this can save me a lot of money

 

Yeah, I learned the either day that my nephew’s wife is not my niece, but I am her uncle! Go figure.

Sounds like a country song.

If you adopt you father first, you become your own grandpa -- and that IS a country song!

 

When my brother committed suicide in 1999, I got to finish raising his kids. So yes, I do think of them as mine. It's also the reason I can never commit suicide, because I can not/will not do that to my family again ever.

 

I have a close relationship to a cousin that is like a brother to me, so my kids grew up calling him Uncle Bill and still do. His kids call me Uncle Sam.

That's actually not too unusual. Oddly, the "uncle/aunt" are the only relationships (that I can think of) that are commonly joined with the first name (usually). That seems to lend itself to other people using those same terms even if there is no relationship. When I was young, there was a brother/sister who were both widowed and lived together with their kids to share finances. As a result, both were addressed as "Uncle Bob, and Aunt Ann" by a good fraction of the house (they had lots of kids between them) and everyone that spent much time there, myself included, just fell into calling them by the same names. In Chinese culture (well, Taiwanese, don't know how wide spread it is in other Asian cultures) it is also common for kids to address most adults as "Aunt X" or "Uncle Y". It seems to be a good compromise between being too formal, "Mr. Jones," and too informal, "Jerry" and maintains the generational respect by not being too familiar.

Oh sorry to hear that, but yes, it's the people that get left behind that have to suffer. You are obviously more considerate and that's the way everybody should be.
