Well, it's a community problem as I explained.  Also, where is the "block" button?

You need to wait until a new post... I'm sure artbyrobot will oblige, and then go to your unread topics list to flag it:

This is not a plastic head thumb tack if that's what you are referring to.  These are metal thumb tacks with metal heads welded on.  Are you suggesting these welds are weak or faulty?  Also to directly answer, no, I've never seen that and would assume that only happens with plastic thumbtacks.  I cannot imagine a scenario where a welded steel thumbtack head would come off under any normal use case.

[Analog Kid]

No, I was referring to metal thumbtacks and yes, I've seen them separate.

Live and learn.

Given that the feature allowing that is off by default, buried a couple screens deep in the profile settings, hidden behind a poorly named option, and the thread describing how to set it up is a decade old... I'm not terribly surprised that more people don't use it.

This setup is not the same as a belt drive though.  A belt drive has a fixed circumference of the belt and the pulleys have to be adjusted to create belt tension.  In my setup, it is a variable length string that is wound up on both ends.  Tension will be created throughout the system when the system is placed under load.  Every single string should be pulled taught immediately when under load as every pulley moves freely and is wrapped by segments of string.  The string wraps will cinch tight immediately when load is placed.  So no, these pulleys do not need to be tensioned by a belt tensioner.  This really is not a belt system at all.  Completely diffent concept and completely different set of challenges and factors.

Loose strings will get crossed on the spool and then bind up when put under load once again. If you wind more than one thread depth on the spool, the string on top will tend to slip between the gaps in the lower windings when put back under tension.
Post a link to a 5 minute video of your 4 thumbtack pulley system lifting and lowering a load to the floor/desktop 15 times without binding.(Strings going slack every time it hits the floor/desk) That gives you 20 seconds to raise and lower the load. I want to see it do this 15 times in a row without fail. Should take only 5 minutes to show this. No need to talk, show yourself setting it up, etc... Edit that stuff out. Just show the entire mechanism as it raises and lowers the load to a resting position.

During my rather long life, I didn't meet even one adult person who saw himself wrong in whatever he used to believe.

Then you've lived a very sheltered life. I've changed my opinion on many things, which I won't list because I don't want to start a political debate. Heck, I've just had a 3 hour conversation with my brother and have apologised to him because I what I thought was best for him 3 years ago, I now know believe to be wrong and he made the right decision.

I wish people would stop feeding this troll.  Please stop engaging with it, PLEASE!

If you don't like it go away, block it, or ignore it. That is not our problem it's YOUR problem.

Agree.   Feel bad for the mods/Dave having to deal with those attempting to shut down the thread. 

As to this being a business or not, it's nuanced.  In some sense, it's just a hobby.  However, because I post videos about it to youtube and have monetization of videos switched on, I bring in money. 

It is hard for me to believe this particular business would show any profit.

Would you consider amazon.com to be a business or youtube?  They did not show profit and recorded losses for many years.  Just because something operates in the red does not indicate it is not a business.  If by profit you mean revenue, it does show revenue. 

Amazon is traded on NASDAQ.  While YouTube is not directly traded, Google certainly is.   Yes these are both businesses.  Stupid question.  What I am not sure about is if the three businesses you claim to own are.   Are you registered?   Sole proprietorship?  DBA?  Incorporated?  Just pretending? 

There were some tax benefits to forming a Class S corp but the real reason was to limit my liability.

Yes, Amazon operated at a loss for years, as have many other companies.
The difference betwixt them and you is that they are ongoing businesses that show business activity in an attempt to make a profit. While you have nothing like that to show the IRS or SEC should they come knocking on your door.

Are you thinking it was a defective batch or are they just known for being incredibly poorly constructed?  This is the first I'm hearing of this.  Visually they look solid.

[artbyrobot]

I'll not answer any more tax questions nor take tax advice.  You all are clueless in that field and it's off topic.

We are all clueless in taxes, electronics, coding, mechanics, project planning, thumb tacks, and pretty much everything else. HOORAY!!!

[joeqsmith]

I would not expect you to comment further about your businesses as I just assumed it was all a front.   At least it's not free energy or warp drives  this time around.  As a matter of fact, I think you are tapping into a new market.   Stay with the religious theme.  It seems to be a very common trend and I would assume for good reason.

Yea I know. I'm sitting her wondering how I made it through an entire career in the aerospace industry in electronics and data acquisition without artbyrobot by my side all the while. Pure luck I suppose.

In the real world, shit happens.

yea in useless at tax,somehow i aint paid any for a few years,and the last time i did try and pay some the taxman sent most of it back.

[Analog Kid]

Now my advice for those who die,
Declare the pennies on your eyes,
Cause I'm the Taxman,
Yeah, I'm the Taxman.
And you're working for no-one but me,
Taxman.

   Did I just read,  someone said that the THUMBTACK's head is not on too good ?

....and I was just about to go away,  and leave the troll alone,  (while I study some more productive stuff).

That's a joke from MASH,  that I stole BTW .

[artbyrobot]

I calculated I need to winch in around 30-32 inches of string and the first pulley could not hold that much string with enough plastic disc sticking out around the string on all sides to help prevent the string from coming out of the space between pulleys.  So I had to restart the entire setup using bigger plastic discs on that first pulley.  After that first downgear pulley, the rest can be smaller but that first one has to be bigger for sure.

Oh good grief.

As to using metal gear servos, I am against it.  It's too loud.  Also, the form factor of cramming a dc motor into a box with the gear train and pcb for it and potentiometer all in one box is bulky compared to spreading things out and customizing the form factor in a way that is more sleek and better able to fit in a human form factor where human muscles would be.  Otherwise you could not achieve a human form factor while also having human level strength and speed.  So it actually is not viable to use products like that.

LOL. Are you kidding? You're worried about what? Noise? Get the damn thing working as a prototype and then worry about noise.

Of course, we are all going to be waiting for this. A very, very, very long time I predict.

[Analog Kid]

OK, time to throw down a gauntlet here. (Fat lot of good it'll do, but whatever.)

Challenge to the OP: Get some mechanical part of your goddamned robot working. Anything. Like, say, the fingers in one hand, or the arm. Anything that you can show to us working, picking up a weight. Repeat the action at least 15 times. Show us that your theories and techniques actually work.

In the meantime: stop posting. Nada. Zip. Zilch. Zero. Just STFU.
It'll be good for you, let you focus all your time and energy on getting 'er done.
Good for you, good for us.

How 'bout it?
We'll be waiting ...

[artbyrobot]

yes, if you want the robot to be doing chores in your home, it CANNOT be this loud: 

This would sound like a construction site operating in your bedroom while you are trying to sleep.  Unnacceptable. It must be as silent as possible. 

Then, to make a noisy gear based robot would be counter productive because you would have to do a total redesign to make a silent version.  Better to do it right the first time.  Better to not waste time building something non-viable.

[artbyrobot]

As to the plain bearing formed by the thumb tacks with #2 fishing crimp sleeves rotating around the thumb tacks, acting as the outer race of the bearing, I recall someone earlier said that this was a loose bearing.  They inferred that the slop was unnacceptably large.  I disagree.  I have observed that the slop is very minimal and impressive.  They really fit as though precision machined to specifications by a machine shop.  The fitment is really that good.  It is perfect.
