Project Weav3r: A LEGO Jacquard Loom
ฝัง
- เผยแพร่เมื่อ 9 ก.ย. 2024
- This is my LEGO Jacquard, i.e. programmable, loom. This video shows it weaving a simple zig-zag pattern, showing how the heddles are set differently for each row.
This is still a work in progress, hence the loom not being fully threaded.
I'll be posting more information on it on my blog in the near future: r.jander.me.uk
A very good educational demonstration for young kids learning engineering 👍
Wow. Love it. More up-close video, please. This is really impressive!
Yeah - I'm well overdue doing some more video of it. I've got some work to do on it over the next few weeks so when that's done I'll try to get some better video shots.
woahhhh... you see me in my profile pic? i am weaving on a 4 shaft floor loom. this is mindblowing, dude :D
Hey, very nice! Now I know how the thread arm works so it does not get stuck in between the other threads.. Thanks for the knowledge!
I'm not sure what you mean by the "thread arm"?
I love it !!! Great job.
Absolutely aw3some Jerry! Just brilliant :)
Amazing~!!
So incredibly fascinating,
Holy smokes! That thing is doing patterns.
Yes, it's a fully programmable Jacquard loom. It weaves 32 warp threads so, allowing for a sensible selvage, has 24 of the middle threads that it can do patterns on.
@@JerryNicholls cool!
@@JerryNicholls Wait, are you the dude with the owl? LOL from linkedin?😂 this thing popped up on my feed prior to LEGOS post..I can't even right now🤣
I think I have talked to you twice on two different sites in the same week, on accident. 😂😂
@@carriekayak8530 yes, I am the one on LinkedIn who commented about the owl.
This is seriously some impressive shit.
Stupendo!!🤩
I need to get one of these so i can make my factory instead of dealing with using the store bought and make better lasting homemade stuff
It's not exactly fast enough for a factory :-) A 2.7m scarf takes about 5-6 hours to make. The recent upgrades to the tension system do at least mean it only takes about 20 minutes to thread and load, rather than the 45+ it used to take.
Amazing
Sensacional!!!!!
Great, look so fun
Very cool!
Where can I buy this machine? How much does it cost?
This isn't an official model - it's all my design. I plan on trying to make build instructions for it someday, but I'm currently working on some upgrades to how this model works. Once I'm happy with it, then I might sit down to make the BIs.
How much would it cost for one to be built for me?
have it run on sheets with holes and the holes program it rather than having it go across and program it look at the jacquard loom and how it works
Thanks, but I already know how a Jacquard loom works 😁 I've done it my way.
If you look at some of my other loom videos, you'll see that it does use cards for the patterns - I use 32x16 baseboards with white 1x1 round plates for the "holes".
Nice but Jacquard did the same without computer 200 years ago and it was like 100x faster :D Jokes aside - this is very impressive work, well done!
:-) Yeah, his did run rather faster than that one does. His was a parallel-Jacquard, mine's a serial version ;-)
@@JerryNicholls Good to know, thanks for the extra info :]
Wow! Just wow!
How many Ev3 bricks were used for the weav3r (not the scanning part)? How many motors and sensors did you use?
That that build there were two EV3s and eight motors:
* EV3 brain
+ X/Y scanner motors, cloth roller motor
* EV3 slave
+ 2 motors for pattern setting, 1 for reed, 1 for heddle lifter, and 1 for shuttle.
The build I have now has three EV3s and 10 motors:
* EV3 brain
+ X/Y scanner motors
* EV3 Slave #1
+ 2 motors for pattern setting, 1 for reed, 1 for heddle lifter
* EV3 Slave 2#2
+ 1 motor for measuring cloth diameter, 1 for cloth roller, 1 for shuttle, 1 for warp thread tensioner.
My current loom is shown in one of my other videos.
excellent
0:49 how to change pattern, what do you device ?
Have a look at one of my later loom videos. There's a pattern scanner that uses 16x32 base board with white 1x1 round plates to define the pattern.
Next they're going to be making a Lego printer. They're practically there already😂😳
Look at some of my other videos - there's a LEGO 3D printer.
@@JerryNicholls wha??!!!!
so everything except the motor is legos?
Michelle Collie everything except the wool is LEGO. The motors are from the LEGO MINDSTORMS EV3 system.
Congratulations, well done, but it is S-L-O-O-O-W!!!
It's perfect for LEGO shows as people can see what it's doing. At the end of the day, it's LEGO, it can't really go any faster 😁
@@JerryNicholls Have you seen Stanley Coates' Meccano loom from 1938?
@@bertspeggly4428 I hadn't but I have now. That is a speedy thing! His works just like a normal Dobby loom, whereas mine's a different take on the Jacquard loom. It's the Jacquard part of my loom that takes the time as each heddle is individually set for each row of the pattern.
@@JerryNicholls People say Stanley's is a Jacquard, but I've always wondered.
@@bertspeggly4428 if you look at the video of his loom in operation, you can see that it appears to have 4 different "shafts" which lift up the heddles in different configurations. That controls the patterns. They're pre-set when laying up the loom.
A Jacquard loom can control each heddle individually on each pass of the bobbin. That's what's happening on the quiet sections of my loom. I have other videos that show that in more detail.
... how many passes before the batteries run out?
It uses the LEGO LiPo batteries and is plugged in all the time to the chargers, so it can run non-stop all day. It only needs to be paused to change the weft bobbin.
@@JerryNicholls oh, neat. It certainly is smaller than the room-size, pedal-powered wooden looms i've seen in my grandparents' village. Jesus those were terrifying when working. 35 years later i can still hear the clanking.
@@GeorgeTsiros it's changed quite a lot since I made this video. Lots of improvements and upgrades.
@@JerryNicholls i like it how you kept it relatively compact. What made you decide on a _loom_ ? Do you plan on improving its speed? "Resolution" ? Do you plan on using it for actual production? I heard mittens are all the rage these days... :>
@@GeorgeTsiros it's a bit bigger now as it's grown at the back - each warp strand is on its own bobbin.
I decided I wanted to build a loom as where I live is the centre of the Industrial Revolution, so weaving is a big thing. Samuel Crompton, the inventor of the Spinning Mule was born less than a km from where I live. I'd seen LEGO looms online but none of them were able to change patterns, so I decided I'd build a Jacquard loom.
As to speed, it's actually got a little slower in an effort to solve some vibration issues - there are floating parts inside the setter mechanism which could jam. It's not really feasible to make it faster. I like it at this speed as it's easy to see what it's up to when I take it to LEGO shows.
The resolution is 32 strands and is limited by the spacing of LEGO studs/holes. Going wider, beyond 32, would make the space required to operate a lot bigger - it takes about 3x the cloth width due to how the shuttle is handled. The pattern occupies the 16 threads down the middle. The 2x8 threads either side are plain stitch used as selvedge.
As to production, it has made about 16 or so scarves so far - one of which I gave to Kjeld Kristiansen :-D It takes a day to make a scarf approx 2.5m long. When LEGO shows start back up, I intend auctioning the scarf/scarves made during the show off and giving the money to the charity the show is for.
how many hooks? what is the design?
I'm not sure what you mean by "how many hooks". As to the design, that's all my own build. I don't have full build instructions for it yet, but have been working on some parts of the model. My blog has more details.
Uhh can you load the instructions and the program up, please ?
I NEED THAT ROBOT
Sorry, I still haven't yet made any build instructions. I've been working on the model again this week, so it's changed a bit more - again! It's a very complex build now, and I'm going to have to dismantle it, to find out how I built it, to make BIs - so I'm a little hesitant to do that at the moment.
I am showing it again in November, so maybe after that I can take some time to attempt at least an LDraw model of it. I have just taken some good pics of it, and will post a link to the blog article in a short while.

Huh thank you so much for the fast replie and thanks also for the time :)
How long does it take to make something
It takes about 20-25 minutes to weave 20cm of scarf. A whole scarf takes all day.
Good job ! Give me instructions please
How long do the batteries last?
I honestly don't know. The model has changed a lot since I took this video. It has a 3rd EV3 running some of the operations, along with new functions. I use the LiPo battery packs, and usually have the charges plugged in whilst running. The main "brain" EV3 doesn't drive motors often, so that one can run for hours on a single pack.
Where is this available for purchase?
It's not. It's my own design. I haven't yet made build instructions.
This is amazing, how do I get one?
That will rely on me finishing the build instructions - I'm about 60% of the way through them. I'm focused on another project at the moment, so I won't have time to carry on with the BIs for a while yet. They're very time consuming and I'll need to dismantle the loom to find out how I made the insides, so I'm not too keen on doing that any time before it's going to be at a show. Also, what you see in this video is a very old version of the loom. A lot has changed since then.
You'll need three EV3s for this model and ten motors, so that's very likely to be a limiting factor on other people building it.
Jerry Nicholls I was just curious, I am in the textile business and grew up with Lego so was very keen
Can I still buy this or do I have to make it?
hunterkono824 it's a custom build. No build instructions yet. One day I'll do them.
have you done it now? @jerry
And another one i've build: th-cam.com/video/82q-jbUNOtg/w-d-xo.html
How to buy this ??
You can't buy this - it's not a kit. It's a model I've made myself.
This is the weavingloom i've build: th-cam.com/video/tvqb4r5aBoQ/w-d-xo.html
It's good, but it's not made from LEGO 😋
It is very slow 🐌
It will never be fast. But that's a good thing. It's great for shows as people can actually see what's happening inside.
It's very creative and cool but you should work on the speed of it. But great job!! I know if I tried this I'd fail miserably😂😂
It can't go faster. The pattern setting system has 32 pins to set etc. It's more to show the process of patterned weaving than producing large quantities of scarves :-) I've actually had to slow it down recently due to vibrations resulting in the mechanism jamming internally - although I'm hoping a change I plan to make in the next few days might solve that.
Jerry Nicholls oh ok well it's still a great design and what ever bugs happen I hope you'll be able to work em out 😀
I'm hopeful that some older Technic parts I have on order will sort it out. The inner workings of the pattern setting system use free floating 5L axles. Whilst the shuttle is passing from side to side, these axles have a habit of vibrating their way back inwards, causing it to jam up when the heddles drop back down. My current solution is to just have the model tipped forward slightly, but that's inelegant. The new parts should provide a little bit of resistance to movement, so it can still be set, but the vibrations will have no effect. That's the idea, let's see what it's like in reality in a few days.
I really need to make another video, or videos, to show how it looks now.
1 month me 1 " fabric making
Lol i rather do it myself... This will take ages
Heh. Well it was never built for speed but, rather, to show how a loom works. I'd still challenge you to set a 32 (individually settable) heddle Jacquard loom by hand faster ;-)
