Open Source Hardware is Evolving
มุมมอง 365หลายเดือนก่อน
Regular companies are "open-sourcing" without even knowing it! Our present view of "open source" comes from software, but every type of design can benefit when they become modular and intercompatible. This discussion covers changes that are ALREADY happening (2024) and will continue rapidly. That is, mechanical and mechatronics products are evolving into modules, which experts can easily build ...
THINK SIMPLE! (mobile robot = mobile sensor)
มุมมอง 111หลายเดือนก่อน
What if we treat mobile robots SIMPLY as mobile sensors? You can think of Easier design projects, better targets, and abundant applications by realizing that mobile phones paved the way of mobile sensors, and solving millions of problems! as of 2024 I see design teams overloading themselves by reinventing ALL ASPECTS of a robotic machine and becoming buried in quantity over quality. Instead, ma...

How to remove the terminals of Molex KK connector, replace the pins, and rebuild. I filmed this with a close-up view in 4k, with lighting as good as i could get. This morning i searched for instructions and could not find a clear video for this. Hopefully it can serve as a quick reference. Key terms: the pins, modify, hack, replace, assemble, crimp, build computer fans, plug, connectors. #engin...

How to crimp Dupont Terminals, and why you SHOULDNT
Me: "Is that a DIN rail mount? Looks like it- YOOOO IT IS A DIN RAIL MOUNT!" I don't know why but I'm happy now. DIN 4 LIFE.
This is also how bro borrows money from friends
Junior year of high school for our pinewood derby in my auto l cad class I designed ball bearing wheels and 3D printed them on our form 3. I won the race by a lot and since then everyone has to use derby wheels provided by the teacher
When do you have to return the tolerance?
Gridfinity and Zack Freedman, anyone? That aside, if pattern recognition means anything to me, it appears like you're presenting what very easily could be part of a paradigm shift for the average person in society as 3d printers become ever more accessible. Assume that the next generation grows up with 3d printers just as previous ones did with the cellphone and the internet, having a catalog of individually purposed designs doesn't cut it when we could instead have access to the customizable and modular design components of our own individual everyday needs. So a catalog of such would be a boon if not a necessity for that. Like its own wiki for 3d printable parts that takes what Thingiverse and printables does to a whole new step.
Some people hear 3dprinter and think they can go and print a car, we're not at that stage yet, printers need to come a long way before they can single pass print in multiple materials, even then some materials aren't printer friendly.
also borrow laminated wood with templates when you want big flat surfaces, it's cheaper and faster.
borrow the weight and inflexibility of concrete, I've seen one guy on youtube do it and I've been doing it myself. also another thing I've not seen a lot is in place carbon fiber casts. (use 2 3d prints bolted together as a press for carbon fiber/kevlar/glass mat, but they stay in place instead of being removed like with a traditional mold), if you print with a 95% infill or so for the top layers, you can get the epoxy to flow into the print and bond very well mechanically. you might want a 3 part mold using flexible filament as a gasket if you do that also use resin that's not viscous so like 24 hour epoxy heated to 30-40C unless you're pressed for time and don't wanna wait the 7 day full strength time.
Look up a term before you say it. Someone just failed materials and processes 101 and it shows. Come make videos once you pass the class
Immediate like just by having Money For Nothing (Dire Straits) in the background!
borrow these nutZ
Bro got the backwards thumb
Putting material with correct property (for use case) in correct location. Thats amazing.
Interesting Personal paper printing is locked in the same thing tho, do you think that will ever change?
Ah wtf do you mean by "borrowing"?
3d isn’t food safe
It’s so cool seeing someone understand that materials can work together, to make up for the others’ flaws/weaknesses. A while ago someone replied to a comment of mine about damascus steel, saying softer steel will make a knife weaker. When in reality, at the right layer count, around 400-600 layers, it gains micro razors on the edge, turning the knife into an easy to sharpen micro-saw blade edge. It’s the difference in steels after being etched in acid that makes it perform at a higher standard. So again, seeing materials come together from otherwise weak 3D printed parts, to make something strong, useful, easy AND cheap to make… is epic.
3D printing was designed to reduce waste in manufacturing. But all these kids making stupid toys and little boats and just all this garbage that will just disintegrate is really reversing what we had planned. If you need a bearing for something just get a real bearing a plastic part on a bearing will just wear away. So stupid
lol man you should teach 8th grade shop, this is literally what they teach.
Mixed media in printing
I wouldn’t necessarily say “borrowing tolerances” actually I wouldn’t that gave me a stroke tbh I had to go to the comments to figure out what you mean
Can I borrow tolerance for lactose?
Tolerance for nothin and my thous for free
This dude making engineers cringe with that tolerance comment
I have no tolerance for 3d printing beyond trinkets.
That's not what tolerance means in material science but I support the action
I'm not going to argue like some others as to what this is called lol... All im gonna say is awesome video dude. Made me look at my 3d prints in another way, I for one, would watch a full video
"Borrow the technology from electronics"
You borrowed nothing from spring steel, the black body of the paperclip is made of spring steel. But the arms you are using on the print are unfortunately only made of steel wire
Fun fact: many caps also have a lip on the inside Jars don't do it but most other watertight things without a seal do
Cool very useful topic
This isnt borrowing, buddy. You cant print every single part. Its material and process selection.
Bro, can you BORROW ME SOME MONEY? 😅
You can do the same as a right hander if you start doing repetitive low impact choirs with your non dominant hand. (For example, start brushing your teeth with your left hand)
fucking thank you bro! Sick of all "3d print only" creators... Seen creators make shit that clearly won't make any kind of tolerance. They simply made it because they could make said thing!.. Not because it could actually accomplish the task they needed to accomplish.. No no no, they just do it because 3d printer..
Can I borrow a feelin? Can you lend me a jar of love?
Just make your outlet a switch
French drain it. Use the tree method. Or make a hydroponic green house with a pump to it. I mean you have the electrical knowledge to do it. You could make it solar but i understand how funds are when making.
Nice plug machine for aerating the lawn, also seeding. Thats not how terraforming works but you are on the right path. It would be done in a much more “unethical scientifically” way. The earth is completely sucked dry of every mineral and compund needed for plant growth in that area. Last i checked you cant even make concrete with their sand. So far they are making little crescent shaped mounds to hold water and not let wind destroy the seedling. They need char, compost, & manure. Also a bacterial micro biome needs to be introduced and sustained. In my eyes africa was either dust bowled or salted.
Sales really are just about marketing and how to decide what audiance would latch onto something so it can spread verbally and sale more.
So borrow a steel barrel and not 3d print one?

Sounds more like "use the correct materials for the task" or Engineering 101
This was super informative and cool definitely following
What is the best way to recycle things like that for 3d printing
This is a great way to describe ways to incorporate materials into prints. We have been doing this in the printed pew community for a while. Some people act like something printed is only good or impressive if it’s 100% printed while ignoring how much you can really do if you incorporate other materials.
It's a terrible way to describe it. That's not what tolerances are and "borrowing tolerances" doesn't mean anything. He's talking about multimaterial parts and would make a good point if it was better articulated. That said, I think it's more about how impressive or convenient fully printed/single material parts are. A gun with mostly printed parts but a few stainless parts like the barrel is obviously the best way to do it, but a fully 3d printed gun that only uses PETG and PLA that can handle hundreds of rounds is impressive. For simple parts it's just convenient to have everything printed, rather than buying parts and doing more post processing. People should do more multi material parts in general, even just with 3d printable materials. You don't need to buy or make silicon parts to make something watertight, you can use tpu to get whatever dimensions you need and it'll be perfectly watertight.
What was that clip at the start from?
Well, you can see TED in big red letters on the stage so try searching TH-cam for "ted linus torvalds interview"
3d printing is the most over used hammer in a makers shop!
i think it’s because we didn’t teach how to use it, together with other tools.
Why do your thumbs do that 😂😂
What is that silicone piece at the end called? I have a piece of equipment that does not include the name of the pieces for replacements
start with gasket or square profile o-ring
