General Technical Chat / Re: H5N1 bird flu and how we're risking another global pandemic

There arge instances of immunization not working as intended and causing untoward reactions when the patient gets infected.  Past RSV immunizations are an example.

No one is disputing that a small number of people will have adverse reactions. It does happen. But rather, for the vast majority of the population (i.e.: almost everyone), it has a positive impact overall.

You can't even attribute correctly which person said what in an internet forum and you are going to build a robot?

Well I clicked the quote button and then going off the text it autopopulated into my response I assumed the topmost line of quote code pertained to the topmost quote and the second one pertained to the secondmost quote which is the most intuitive way of reading this.  It is not using brackets which makes it confusing - look at the code it produced:

quote author=xrunner link=topic=426607.msg5483182#msg5483182 date=1714776514

where the hell did all that text come from?  Did an actual person come here and type all that?  LLM?

so anyways, I did not claim to be infallible which it seems you think I must be in order to build a simple robot like this.  This is easy stuff really.  Wait till people create way more advanced robots with nuclear power, living skin, living blood, etc.  This is all childs play still.

Projects, Designs, and Technical Stuff / Re: Connecting old handheld Magellan Explorist GPS to computer via serial

You can look it up online, but I remember it as USB. I also remember probably having to load a serial-USB driver so it's basically serial. I think it could download waypoints, but not sure. I mostly used the computer interface with an obsolete program to average position and improve accuracy. That might have been when GPS was purposely randomized with "selective availability".

Since carrier waves are the key, the transformed energy from the device will be lost at a specific frequency the participants displacing it in the capacitor & transistor fields. It's probably extremely low frequency. So the waves end up clear out in space charges the oxygen and zapping all the gases hardness away as it rises up.

The schematic is a way to circulate negative energy out transform it to positive abd place it heavy as it gets back into the device like titanium with gases that transform it back and forth on a natural 555 timer.

Since I designed how they make capacitors don't expect your average capacitors to work with me unless they feel so caught I would coup their operation and make myself look like a fool to billions of scientists. Which I'm tired of having occur.

Test Equipment / Re: Siglent Bench DMMs SDM3065X, SDM3055 and SDM3045X

This is the ref I was using. I think it did pretty well for what it is. The lower voltages certainly appear more stable; though I've never run the other voltages as long as this test.

I'm trying to be nice (it's pretty hard for me  ), but I'm halfway thinking this is all a joke. Maybe this person really thinks this is the way to build a humanoid-looking robot, but it's ridiculously complicated. For starters, there is no reason - no reason at all - to try to duplicate the bone structure of a biological organism when much more efficient and stronger frames would be the way to go. All you have to do is look at what has been already achieved. All those pulleys and lines would be a mechanical nightmare to get working and maintained. And the software ... there is a very good reason there are teams of very smart people working on these things - because it's very complicated.

Hey - but he can do whatever he likes to pass the time with a hobby I suppose. 

@xrunner: Yes, I wrote all of that.  Took all of 5 minutes.  Fast typing flow of consciousness style.  Not hard.  And no, LLM's can't produce writing of that quality level that is 100% logical and rational.

@smokey "thinking this is all a joke" -- it's not.  This is my passion project.  And saying it's a joke is rude IMO.  You say "it's ridiculously complicated" --- I disagree.  To meet the goal of human level strength, agility, full flexibility, balance, athleticism, speed, etc, one has to match 1:1 every pertanent muscle and bone in the musculoskeletal system.  No robot has come even close so not sure why you suggest copy other robots which don't look human at all which goes against the stated goal of the project.  Also, you claim human-bone structure is not ideal.  I strongly disagree.  It is extremely well engineered and optimized design along with the muscles and how they all interact.  You cannot improve on it. Here is a well spoken CEO that has the same view on biomimicry with skeleton and muscle system copying directly from human body as I do:  https://youtu.be/GnXdsogPwOI


You say "All those pulleys and lines would be a mechanical nightmare to get working and maintained" --- I disagree.  Also, I challenge you to present a alternative that is equally silent as a way to downgear motors.  I dont' think you can.  It is completely necessary.

You say "and the software is complicated" --- so by this you infer it has to be done by a team and an individual cannot do it?  I strongly disagree.  It is very doable solo.  Who cares if it is complicated?  Anything complicated is easily broken down step by step into something not complicated if you know what you are doing like I do.

Repair / Re: Xantrex/Sorensen XHR 40-25 schematic?

« Last post by ifonlyeverything on Today at 02:34:20 am »

C151 and C239 were tantalum, replaced both with ceramics from my eBay TH ceramic kit. The others I replaced were electrolytics.

Connect input o-ring terminal to the shield by short wire. Switch on and check for self oscillation.
