Open Source Hardware is Evolving
มุมมอง 355หลายเดือนก่อน
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 105หลายเดือนก่อน
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...
Disassemble Molex KK (close-up) Connector
มุมมอง 2623 หลายเดือนก่อน
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
What was that clip at the start from?
3d printing is the most over used hammer in a makers shop!
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
Only one of those was tolerancing, tolerances how much room you have for error this is combining material properties, I guess the tolerance comes from the fact you have to account for the material and its properties and whatever form it's delivered in?
You’d make a good professor
Now show this with 3d printed guns!
Yeah adding metal pins would be good for 3d printing or nails screws etc
This idiocy is why i dont click on shorts ever. Learn what “tolerance” means.
I find it easier to hold the pin lightly in the jaws (usually one click) and then pull it through until it limits on the shelf. This saves you dropping the pin. To strip the right length of insulation I have mounted a spare pin on a piece of wood and use that to to check the length of the stripped wire. I use silicon insulated 24 AWG wire, you can strip this with your finger nails, no chance of nicking any of the strands of wire! My crimpers don't crimp the insulation properly either, a right PITA.
A mini tubing (pipe) cutter is cheap & no power or PPE is required
Can i borrow 1million dollars?
yeah print in place and snap together crap is nice. but you gotta use hardware to make a solid design
Well explained short. Hardware selection is everything
At work, we're borrowing tolerances from CNC machines. We combine them with cast steel parts. 😅
That's not what tolerance means. But combining material properties in your assembly is always a good idea.
yeah, the accuracy is still limited to how accurate the printer is and most of the things he talks about arent even related to tolerances
maybe the Rack Robotics Betta Wire V1 is something for you.
This is an interesting framing of the problem.
Your fans are made for two different purposes, look at the hub and blade size differences. One of the fans is blowing air into a wall and then that's being deflected 90 degrees up to your measuring device while the other has zero restrictions and is measured in a straight line. PSU on the extraction fan is designed to have the load of the filter, so it's unlikely it's efficient when that load is removed.
I was too distracted by the background music to understand what "borrowing tolerance" means.
Sounds less like borrowing tolerances and more like combining material properties
Sounds like hes just trying to brand his own technique something that is not a single unique phenomenon. That's like telling people your food is going to borrow spiciness from spice and saltiness from salt. It really distracts from the message which is essentially saying 3d printers are great tools, but recognize where they fall short and don't feel like you have to 3d print every component such as screws, gaskets, and bearings.
yes and the tolerances are still dependent on the printer, all other parts around a 3d printed part have to rely on the accuracy of the printer
Ball bearings, bushings, metal reinforcement that gives straightness ect. The "borrowing tolerance" comes from parts like that.
@@FPVtrix bro does not know what tolerance is
@@niil047 kid you probably haven't made anything more functional than a benchie 😂 start with a trade school or something before you pretend you're an engineer.
You should try parametric design and configurations in Fusion 360
Solidworks is the industry standard engineers use.
Yes! 3D printing has so much use even if it has supplemental aspects. People obsess over making 100% printed stuff, which is fine and a good challenge. But you can open up far more opportunities if you just use 3d printing as another option for making whatever it is you're trying to make.
WOW so what your saying is the things we already use everyday combined with your shitty 3d prints make them slightly better? WOAAAAH! careful it sounds like you might be close to inventing the wheel.
More like borrowing material properties in most of those cases. Ball bearings fit the bill though.
Can I borrow some tolerance please? it's for my GF. she's grown extremely intolerant. When I told her there may be a way to fix her she just got worse. I don't understand.
i have a severe tolerance deficiency, can i get some too?
I have no idea what this means but i need to know more now
Smart
Great idea brother
what is? Not using metal as a tire? Oh wait what? we don't use the same material for everything? NOWAY

One thing I found was that the tube into which the wire is inserted has a split on one side. I always try to make sure the 'lump' in the anvil is opposite that split, to prevent the 'lump' from widening the split and ruining the crimp... Good video, I enjoyed that.. Thanks..
If the wings aren't crimped properly, just crimp them again in a smaller cavity. I usually crimp them twice by default and it works like a charm every time. Much easier then trying to fix them with regular pliers.
Good comparison
You forgot a check mark under robots.
Tbh, I'm so tired of applications, software being paid version, as a thesis student I needed few software but I couldn't get educational license, all say yes we have edu license but you have to pay few hundreds of dollar, if only studnet was able to pay such amout. Bentley and other slope stability software , I can't believe we live in a world of Linus Trevold. Such restrictions surely will create more tpb website one day
You mean, you can't believe Linus Torvalds paved a way for exchange of free software, but important software is still locked behind paywalls? What is a TPB website?
@@davidmalawey yes, you got exactly what I meant. Website the one n only, 🏴☠️ 🏖️
Excellent video!
Thank you so much!!!
Glad it helped!
You need some way to control flow rate better, also the pressure must be consistent, those small variations get heavily amplified. You could try those water storage bladders/accumulators they sell at the hardware store, followed by a simple valve. Then you can ramp up the velocity to find best speed to maintain laminar flow.
Great Video Sir! Hope to see more educational content like these in future.
Barge cement, period!
Still helping :)
Straight to the point and well laid out. Thank you klsir!
Would it be difficult for you to speak loudly enough for someone to hear you? Just a question...
noted.
i like your style mate.
Interesting keep it up
I could talk for hours about this, maybe weeks - and I have no idea where to begin. This space probably deserves its own podcast, but I don't know which parts people need to hear. I'm always open to comments, that can feed into a topic.
thats just hp now
It would have been nice to also add mineral oil to the test.
28 AWG? I use 22 AWG stranded wire and it works fine. It seems evident that smaller sizes will also fit.
Thank you!!
Thanks man, you explained it really well.
