Obviously he is as good if not better a family man as as you are engineer

I agree fully. I have respect for him being an engineer, father and husband and willing to show us his human side as well.

Team?

Super dad

Hello, My organisation in kenya needs to test the industrial robitic arm concept how can we reach out to you?

I figured I might see you in here. Great content, both you and Jeremy

i would be happy to have on of them motors to make a simulator racing wheel,, they really cost much, and when see is burning ohh :(

Absolutely seconded.

also, analyzing the *decision making* that went into causing the mistake, means he learns from it, and we learn from it. sometimes its hard to admit being dumb, but the upside it to learn why you where dumb, and how to do it differently next time. Better labeling, or better yet, key the plug so they cannot be swapped accidentally. Sometimes this is as easy as removing/adding pins, sometimes, it requires selecting mechanically incompatible connectors (like he hinted at).

I Really liked what you said, Lotek Nomad. My Son has this saying, "Only you Mom". lol He refers to my teaching him what Not to do. : }

Humans learn from mistakes. We can either learn the hard way from our own mistakes, or the easier way from other's mistakes. While it is good to strive to not serve as a lesson to others, it is noble to step up and share one's errors to help others avoid them.

Couldn't agree more Lotek!

Immediately Subscribed!

I was wondering how many English speaking people in the world today are adept enough to comprehend his treasure trove of material. That’s not a slight on English speaking folks. I just assume folks speaking other languages would be quickly lost without hearing his knack for teaching as he guides us through his journey. Jeremy’s in my top 5 for sure!

he is actually doing pretty good for not intentionally destroy or blowing things up. haha

@@dmbworks8094 The whole scene needs more exposure. It’s a category I don’t get recommended enough on my home page.

@@JohnDuthie just saying compared to others doing this on youtube sci/tech he has a big following. without saying sci/tech needs more exposure as well as he. but just not sure how big it is of interest to the average youtube watcher if it doesnt explode. there are some really talented youtubers that dont get near the following as the ones going by the seat of their pants. im a new sub here, i like what he is doing and offered to help with the equipment i have if i can.

The question of funding goes unanswered...

If you havent done it atleast once you probably only just started. Theres a reason I prototype my projects on knockoff arduino boards and save the real ones for the final iteration :)

I think I have a box of IC's that have suffered my late night "oh hey, lets just get one more thing wired up, I can do this!!"... zzpfffft.... shit, well I guess I have the make a wish the genie is out...

@@prozacgod I hate when I accidentally let the magic smoke out of devices v.v

@@didiwin78 Smart!

I remember those days...

To think everything is hand made is mind blowing.

@@benniedonald Goals. We can all do this.

@@dungc6479 Looking at his shop, a lot of money was spent as well, appears to be a full time gig... this is how that works.

My favorite will always be the washing machine break-down. I now have a giant square shaped planter out of an old washing machine, lovingly rescued from the side of the road. (gardener here)

He still isn't talking to me despite many apologies but we are working through it LOL .

Buddy, what's wrong with getting fried? lol

@@JeremyFieldingSr Soooooooooooooooo very frustrating when it happens, my friend, and so easily done. The number of times I've saved a file under the wrong name (prior to when OS's warned you you were about to overwrite something) or have done exactly what you just did plugging the wrong plug in and letting the smoke out... It's not so bad if (like my plasma speaker) things just blow up for seemingly no reason at all, but so much worse when a moment's inattention which usually results in us questioning ourselves if we should triple check before power up.... "nah! I already checked twice" we tell ourselves. We humans are lucky our legs don't twist in certain directions. we can't actually kick our own asses with any great force. ;) Still a banger video though!

@@jimmyb1451 Learn from aviation: Good pilots adhere to a variety of written procedures that they learn by heart but anyway read. The exception happens only when something much out of the ordinary seems inexplicable and demands team work to decide what to do, given the circumstances. So there are procedures for this, for that, and for that other... a long list of drills. Some are performed in sequential order (and their completion is announced out loud for all the team to hear): normal operation procedures. Some other are called for in specific but abnormal circumstances (I remember, for example, Operation in cold weather) or in emergency situations. So: prepare and write your drills, each with a name (what phase you are, or what main thing is done in the procedure) and a list of points to first perform, then re-read and check that the settings are as the list demands, even if such a list is very short (and it should include whatever security and safety issues could occur during that phase, i.e., checking out fire extinguisher is nearby and full, gloves, masks, apron, and boots are worn, no unneeded flammable material nearby, etc., in the Before Welding checklist). When the next procedure requires such prior checks and actions to have been done, you know you've done because you just declared that procedure completed. So, you start this next procedure and go on safely. After-this or -that procedures may also be useful (generally brief drills). Drills may also contain some piece of advice on what to do or avoid if certain things are this or that way. This procedural method saves lives and wealth, and sometimes it even saves overall time spent!

@@wafikiri_ What you're describing reminds me of "pointing and calling" a safety protocol used by Japanese railway workers and others where you point and say/call each step of procedure. en.wikipedia.org/wiki/Pointing_and_calling

*an intelligent* / *You're definitely*

Yeah, that's why he mentioned you should avoid welding after milling if possible.

specifically due to the thermal expansion of the metal you are welding. The molten metal, in it's molten state, is notably less dense than the cold metal on the other side of the part, and as it cools it contracts until it reaches the same density. Because the metal hardens before it is entirely cooled, it still has contraction to do after it becomes hard, and thus it creates a good deal of tension on that side of the part which tends to bend the whole part in that direction. Thus, welding perfect right angles into parts too large to clamp to a table is a very challenging task indeed.

@@reaganharder1480 and then no worky?

@@vennic well, your precision machined stuff may no worky. If you're working on a project with relatively loose tolerances, it probably still worky.

@@reaganharder1480 so the heat from the welding is distorting the shape, but what about the strength of the metal? weaker now that its temp spiked ?

Yep just like a 6 can be a 9 or an 8 can be either or a 3 if there is a smudge.

Its the same reason S and O and I arent used in auto VIN numbers.. Tooneasily confused so we just dont use em. But in the home shop... These things are bound to happen as one point or another. It's all about how you handle it. And Jeremy takes defeat like a champ. I can really appreciate that.

@@kjfuson92 the letter S is used in some VINs (European IIRC) but your point is solid. I wished manufacturers would avoid using similar letters in part numbers, although I get that there are technical reasons why that probably isn't possible. In practice, a label maker and a clean font will help in the future.

considering the motors are new and not pulled from old equipment i'm sure the encoders could be purchased and replaced for a pretty minimal cost. Automation direct has their name on them but I think they are sourced from either Delta or Yaskawa. Parts should be cheap and plentiful.

Yeah, I was thinking that too. If its just the encoder thats blown, that might be a replaceable part. Tho I'd probably do the same as he did and just order new and then look to repair when in a better frame of mind.

I really like this way of thinking, and hope we get some videos on him fixing the encoders using Louis Rossman style repairs XD

@@robosilo Where's a good place to buy industrial motors ? Alibaba ? I'd like to do a direct drive sim wheel eventually

@@frenchonion4595 I've had good luck with Leadshine brand products. There is a US distributor called AMT that sells their servo/stepper products. If you're looking for single/3 phase induction motors, its hard to beat the selection of automation direct.

yeah but where is the STL for it?

@@charlieroney1008 Fair point, but given all the hand-made steps, would you want to support people in a project like this? Lot of liability, and lots of room for error that our guy doesn't have control over. I wouldn't want to support such a complex project.

@@The-KP yeah but I am on my quest to actually acomplish all of this like I actually want to do one of these giant robot arm builds but theres no info on what drives the ones maybe bigger than jarvis as for liability he has none if I deicide to be a dumbass with stuff i decide to make myself its not like you cant go build an AR4 robot arm that can do most of the same things I just want to move like 10+pounds with my arm. in a larger size

@Charlie Roney Right on. His KZfaq About page has ways to get in touch with him. He has a website, maybe more info there

Also I think the order of operation matters simply due to warping caused by the rapid heating and cooling when you weld. This could distort the part and the accuracy of it after machining.

This one took me a while lol.

Vera, vera funny

always let them do theirs first.

Me too, I'm hooked on scrappy!

I've seen the same done on a professional project. Always worth double checking power polarity as-wired before you connect - designing for testing is difficult though.

Don't think that'd work. The fuse blows on current, not voltage. And thanks to mr Ohm's law, a lot of damage could be done by 24V before a fuse that is suitable protection for 5v blows. I could be wrong tho. You could build over voltage protection into the circuit, but easier to just label things better.

@@DarrenPoulson That's true too. I'm by no means an expert.

@@hardwire666tooNaaa, He knew the solution and stated it... different voltage, different connector... Kinda why it's even more painful to him I think

A fuse followed by a MOV (Metal Oxide Varistor) would work, commonly used on AC mains, but you can get ones suitable for 5V circuits (5.5V MOV).

@@DarrenPoulson But it would be a fun video to see how to build overvoltage protection into the circuit. I certainly don't know how to do it yet.

I can confirm... you are indeed first LOL! And thank you :)

Congratulations

I like the way you took a break when things go wrong. I go get tea. Great channel.

Professor google says that type of belt is called "Helical offset tooth" and it reduces vibration and makes the drive quieter. Another possibly solution for the connectors might be pin keying. If he has extra pins in each one, he could remove different pins from each, and plug the corresponding sockets, preventing the wrong pins from going in. Of course that way you could bend the pins by forcing it, so it's a trade off.

Another reason, to add to what Nick said above, is that when the belt has chevrons like that, the pulleys don't need flanges (lips) on the sides to keep the belt from rolling off the pulley; the arrows keep the belt centered automatically. Not needing flanges would make the pulleys slightly narrower, which would be good for this application.

Always known it as HAZ heat affected zone.

I think it's "weld distortion". Meaning, the warpage from heat that ruins machining level precision. Think what a can looks like if its been in a camp fire. There are some good videos about it on YT.

@@allananderson5840 MN. I. O o. O. Non pp p. P. K. . P. M... . P.

Probably not HAZ unless these are all on critical material strength locations. Most likely because you will always gets some warpage when welding, and this can easily throw off tolerances.

Now that's something I'd dedicate hours to watching if they ever posted something that long. But we should have a backup plan in case they cause the end of the world...

@@faielgila7375 I’ve thought about it more… Imagine this: This Old Tony, Colin Furze, Smarter Every Day, Stuff Made Here, Integza, Mark Roper, Jermey Fielding, Matt Parker, Make Anything, Styropyro, NileRed, Teaching Tech, Tom Stanton, Veritasium, and 3D Printing Nerd (or more, or less) network and take on a real world problem, and solve it through crowdfunding and engineering solutions. A pyramid scheme, but for ideas and solutions. They could reach out to their specific communities and crowdsource/delegate individual pieces of the overall project. The KZfaq creators would be the project managers for their part of the solution, using each of their communities as resources. In a matter of months, there could be thousands of makers, engineers, programmers, physicists, mathematicians, and chemists working in the same direction to solve a global human problem, instead of each of them doing siloed projects in no particular direction. Baseballs breaking the sound barrier and pool cues that can’t miss are cool (really cool) but not really pushing humanity forward. The beauty of this, is no single person needs to take on a huge amount of responsibility or dedicate huge amounts of time, other than a Google/KZfaq rep that keeps tabs on the project as a whole. A project like this would get global attention from everywhere, and create thousands and thousands of hours of KZfaq content. Sponsors would be all over it. Realistic ideas: *A realistic automated recycling solution- The world’s current solutions for recycling has completely failed. To fix the problem, there needs to be solutions from sorting at home, to industrial sorting, to supply chain. Plastic testing/sorting. Cleaning and processing into raw materials that are actually ready to be used in industry. *Home automation- affordable kits that can monitor use of electric, water, and natural gas/LP and manage each effectively. *Climate change- look at what can be done to improve carbon emissions by individuals. Tiny changes to each of our daily lives can have large impacts. I’m sure there are engineered solutions that can make our lives more convenient, and lessen our carbon footprint. *Affordable water purification- A lot has already been done in this area, but clearly there is still room for improvement. *Affordable and fast housing- 3d printed houses are happening, what else could this group of KZfaqrs come up with? *Home-based product manufacturing- home robots of various sizes that can perform various tasks. Some useful, some fun, some silly. Zero-point production isn’t just the future of energy, consumer products are heading that direction too. *Efficient food/plant production- automated vertical vegetable gardens, grains, mushrooms, root starches, latex (rubber trees/plants). If we all spent 100 hours spread across a couple years, we could solve these problems permanently. We just need some leadership to guide us and manage our efforts. @Jeremy Fielding Please go talk to your KZfaq buddies and KZfaq representatives to see if there’s any interest in this. Sorry for the novel.

don't forget @skyentific and @James Bruton

@@GeorgeDolbier I don’t know those channels. I’ll look them up.

@@nickdarrow4873 Now that's an epic idea! I'll be tackling clean energy with thorium reactors -- you think NileRed would lead that one?

So cheap in the manufacturing and materials or what?

Lol, that’s true.

I've heard this old Tony say that weld joints can pull things together - as the weld cools it contracts with an incredible amount of force, enough to pull things out to true if you don't plan your welds sufficiently I've never done anything precise enough to worry about these forces so idk the full extent, just quoting ToT

Or just color code them, heat shrink comes to mind.

Great idea! Make keyed shrouds so you literally can't plug the wrong ones in.

Correct, he was aware and took the chance.

Smarts are one thing, but the dedication to pull that off in your garage... That's blows me away.

You can learn it too, man. That's the great thing about stuff like this. It takes effort, but if you have the drive, you can accomplish the same thing or even better. I honestly think that's why he's sponsored by that company from the video. Start from somewhere and build on that over time.

He's definitely got me beat too. Depending on how interested you are in the electro-mechanical fields, you might want to look into Arduino as a starting point. It's a lot of fun and a great way to learn about electronics, programming and combining the two.

It's all about passion, find your passion and it is amazing what you will overcome to feed it.

Well that's why he makes these videos, so you can learn to do it to. Knowledge is power. If you've ever built something out of trash, you have the drive to build a manufacturing business. Most businesses are made out of trash, anyways!

Yeah, that was pretty much my answer to 8:29, so…. I’ll leave it at that!

I prefer seeing various angles. And seeing the cranium from the side.

Thanks for the feedback. While I plan to do this slightly differently in the next video, I did not invent this technique. In fact nearly every interview-style TV show uses two camera where in the person doesn't look at one of them. Search for "two camera interview" and you will see lots of examples. It's very common, I am just experimenting with how I want to do it.
