I love being able to hear the difference when the motors are powering the light
Yeah why is that?
@@I_killed_that_beard_guy because there is a load (the bulb), so it's more difficult to generate the same voltage as before, and the motor slows down
@@I_killed_that_beard_guy When the light draws current, the motor creates opposing forces (eddy currents)
@@waldolemmer thanks
It's one of my favorite way to visualize the concept of "borrowing" energy, and not "generation" of energy. And also to negate all those "free energy" stuff
As Lego combat robot builders, the chain test has got to be one of the most important discoveries made in a long time. Thanks for doing that!
A logo combat robot... that sounds sooo cool
@@rivahoukes1554 Can confirm. It is just as awesome as it sounds.
@@rivahoukes1554 just check his channel
Huh. I'd always put chains on gears with slots facing inward without giving it much thought, assuming for some reason it'd be more structurally sound. Today I learned outward is technically better. Thanks!

I've never thought of generating electricity with Legos but now that I think about it, it's really cool
Time to build a Lego car now that he has electricity
Well electric motors are just generators if you spin it manually.
You can make a mechanical wind mill that lifts the weight, then drop it to power a light.
But wait there's more
If you get the 7142 motors and connect them to each other, they turn at almost 1:1 under no load, its amazing how well it works even slowly turning it. Newer motors work no where nearly as well.
It makes sense that the chain links facing outward would perform better with increased torque loading. When the gear pitch angle pushes the chain outward, the outward facing links will not pull apart
I think exactly that point may have been overlooked by many people - if done right, the chain links may be considered a reliable power transmission. Another great tip for long distances of chains running free: They will vibrate in form of a sinus ware, therefore adding a part at the inner side for countering the wave out also helps a lot - because if one imagines the chain links in a still show when they are forming a form of sinus, some of them also get in the bad angeld position of the pin opening allowing the pins to slip out more easily.
I loved the close up shot that showed exactly why the inward-faxing chain was weaker
You're thinking of pressure angle, not pitch angle.
@@SuperAWaC quite right!
Inward will be better if u looking for a way to NOT break any chain link. At given too much force it will pop up more likely than break. I think. Corect me if im wrong.
Try to squeeze as much time out of that "Gravity Light" system as you can, maybe adding weight and using pulleys? It just feels like that concept has quite some potential. 👍
it that a pun
@@demiurge67321 I didn't even realize that lol... I mean, yeah, it was totally intentional :)
Increase the gear ratio and the weight. Then strengthen whatever breaks. Use the usual techniques to reduce the friction in the gear train. Refer to older videos on this channel to see examples of gear train optimization. Keep increasing the run time until it is time to edit and publish a video. I suggest reporting the run times in terms of seconds per meter of drop. [Edit: I originally wrote minutes per meter, but that adds an extra conversion for a high school physics student putting data into standard units.]
@@hamjudo nice, exactly what I meant 👌
That feels like to old mousetrap cars
It's amazing to me how attaching the light audibly slows down the RPM.
it increases the resistance on the generator 😁
I agree. It's so cool to see how these physical things actually interact with each other and know why it happens.
v5 GG 👁️😠👄👁️🍳😋
@@fayemedina4921 The garbage you just wrote gave me cancer
True, it’s super cool! And on the voltage meter you could see the voltage reading decrease a lot too
Depending on which side you point the chain, it can either be a very strong link or a failure point. I think this might be intended, considering there's other methods to link up plastic chains that are stronger (old Xerox printers, the big ones, had plastic chains, they were quite strong, but if you exceeded the breaking point, they'd snap).
0:41 You can really hear the power pull on the generator Slows it down a bit

That falling weight light thing is actually so cool. I can see something like that being great for children as an alternative to night lights, so instead of having a light on constantly, the parent just clips the weight to the top and it goes down. 5 minutes may not be enough, but with a better similar system you could quite easily draw it out to 15 minutes, which should be enough to fall asleep in, or if not then just do it again. It would also work well for night time toilet trips as a temporary light source that goes off by itself.
you can just buy LEDs that are on custom timers, and it would be a lot cheaper. You can also buy light switches that are timers; I have one for my bathroom fan
Based off pfp
Yoy can also get like a led light with a timer. Wouldnt make any plastic whiring noises either
@@QuintonMakaio point is that those use power, this is making its own.
@@metformin3154 sure, but an led such as this could be powered by a single AA battery and last for weeks
The biggest difference for chain link orientation is if they are used as treads, for a small powered tank for example. If the inwards method is used, obstacles will very often cause the chain to split, while if the slots are oriented outwards, the chain will hold.
2:54 *YEET*
2:30 This sounds like the cars did in the Lego racer games :)
2:40 cool beat!
Can I just say that I love the sound that the 71427 makes when you spin it like you did at the 1-minute mark? It's very unique if you ask me.
That test with chain was genuinely surprising.
Комментарий в поддержку канала и ролика, а также труда лего-мастера.
At 0:14 it sounded like that creepy noise from Minecraft
You mean the hidden Creeper noise?
I didnt even think of the differences between inward facing and outward facing ones would have. Now that I see it, of course the inward facing links do poorly against higher torque! Love your videos man, keep em going!
That's cool. Can you set up that gravity light with a ratcheted lego chain. I can even imagine opening a closet door that pulls the chain, charges the mechanism and give you enough light for a couple of minutes. Always loving your video, thanks for making them!
Nice, like it that you can hear the motor work harder when you put on the light. shows that used energy needs more power
If you had two high speed spinners going opposite of each other connected with a lego, could the lego tear in half?
he tested that with an aluminum rod a few years ago and snapped it clean in two, so a lego brick is probably just as screwed
@@youmukonpaku3168 Oh cool, I only recently found this channel so I haven't watched all the videos yet
this is awesome. I love this. More power generation idea's would be cool. Like a bunch of generators in series. Also maybe hook them up to a windmill turbine?
I've watched every one of your videos and I don't know if I'm the only one who is highly addicted to the building sounds from your older videos? The clicking crackling and snapping is so enjoyable! Make more building videos of the older style 😎
This series is starting to remind me of the old mythbusters!
Would be cool to see different variations of the gravity light

These videos are perfect for when you're on a lunch break.
The end of this video is crazy!!!.. love having the answer for the chain inside or out!!!
1:22 lowering 0.9kg for 1m over 300 seconds (assuming g=9.8m/s^2) ideally generates 29mW, so with the voltage of 4.4V it would generate (maximum) 6.6mA.
NERD
What I would love to see is a thermic engine, like in RC cars, used with legos, with the requiered precautions regarding thermals of course. I've never seen that anywhere despite searching for it, and I'm surprised that people are not even trying.
Fascinating! Learning some cool principles here.
Love these experiments, keep em coming
Do a Rube Goldberg please!
Thank you very much for doing this extensive testing regarding my question / observation of the chain links. ❤ For all who are interested in seeing more of my RC Superbike project (a fully functional RC motorcycle made out of bricks) may visit the projects' playlist: kzhead.info/channel/PLzvdTW1ku_J92taKmm1HXZ6wYnRwD1j8y.html
Very interesting test results. Since the chain-tracks are always assembled slot inwards, this suggest to make supplementary chain drive by a slot outwards standard chain, if utilized as heavy load conveyor belt.
Love this series!
It would be great to demonstrate concepts like energy, power, current and voltage using LEGO motors. Thanks for another fun and interesting video.
Only thing wrong with this channel is the low amount of uploads :P Keep up the good work!
One thing thats fun is to connect two motors electrically AND mechanically in a way where they are opposed, resulting in them acting like brakes
These weekly Lego experiment upload schedule is getting more better
I loved the Lego grav light, I wonder if there was a way to make that more efficient to power something bigger?
gravity battery
At its core, it's what pumped storage hydroelectricity is. Gravity pulls water, it turns a gear, and produce electricity.
Reminded me of one of those old clocks.
You could use an RC brushless perm magnet 3 phase motor, they are more powerful and likely to last longer
@@cleyfaye Hadn’t thought of it that way, but totally.

Slots outwards always, thank you for this information
Differential gear drives would be reay neat to see!
What a great demonstration of the physics of power generation. I love these videos; Good science, practical uncluttered demonstration, no nonsense or filler. Great!! I could watch this kind of science all day; with box of lego to hamd. The sprocket chain question is interesting too. Yes, the chain can handle more torque with the quick link hooks facing outward but to answer the question more accurately.... I suspect Lego designed them to come apart at a certain torque to prevent them from breaking. With the hooks outwards they wont be forced open by centrefugal force but they will stretch and produce slippage which will shred the gear teeth. Using a chain tensioning mechanism prevents slippage but allows more strain on the hooks which will snap or at least deform. Like I said, This video and methods are Good science, Good physics with easy to see demonstration of the facts and principles. School would have been much more fun and easier to digest with this type of experiment. Thats why im really happy about the current (2022) influx of S.T.E.M. construction kits available now at low cost and in use in schools.
I never realized that legos had such POTENTIAL for energy. 😉😂🤣
for a minute, the first one looked like free energy, then I remembered that voltage and amperage aren't the same thing and there is still more power being consumed by the drive motor than is being produced by the driven. Powering a light bulb demonstrated that pretty well considering how much of a load the light bulb put on the drive motor.
Gravity light idea was awesome
I was curious about the chain as a kid. I would link them in alternating pattern because I thought one side would be weaker than the other depending on application.
Cant wait to come back in a 10 years and find that you’ve made a particle accelerator out of legos.
dudes been having a nice flow of videos nowadays
Great idea to use the gravity to produce light ! 5 minutes is great you just need to have a way to bring the water up and you have a real light !
the inward vs outward was interesting, and informing.
3:18 Bless you
Thanks for the valuable info👍
Could be cool to build a funicular railway, uphill, turns.. heavy weight ( 1kg ) uphill, kitchen counter / stairway.. ! Or one of them Ski lifts / cabin lift
I was waiting if you could make an air raid siren
This man here is making energy out of legos, and I’m struggling to make a car
The gravity light is a good idea. They should be using the idea with solar during the day to lift weights/spin up a flywheel, wind up a spring/pumped hydro, for use overnight night. How about a lego waterwheel to produce some power?
Another interesting experiment would be to drive legos with miniature petrol engines.
Idea, you could solar power the battery for the generator, and then use the generator for one of your house lights haha
I actually increased voltage like that when I was a child and I was very proud that I invented a way to make the lego lamp much brighter than normal :D
It’s amazing how we went from barely knowing how to use a circle to making fully functional machines out of a children’s toy
Push the gravity light idea to his maximum! Looks like effortless light! Gravity does all the work
Watching this feels like watching redstone experiments
Please make an updated compilation of your breaking moments so far!
You are amazing, love Lego, love the gravity generator idea, I love this!! I’ve been thinking about this exact idea for a project I want to do. Can this be taken further with a heavier weight and more gears to generate for an hour? I would love to see how long you could generate electricity in a future episode. Thanks, and keep building!!
Suggestion: 1. Test and measure how much Lego pneumatic pistons can pull or push on different pressure 2. Build a Lego pneumatic engine (LPE) using pneumatic pistons and power it using real compressor to test how much rpm and pressure it handles
One of the most interesting channel on KZhead
I would like to see your entire Lego collection
this man is prepared to create his own machines on the end of the world, mark my words
I never really thought of light being able to put a load on the gears and cause some resistance. I mean it makes sense, i just never really thought about that. That's insane
i've never thought about creating electricity using gravity, amazing
That's how hydroelectric dams work. Water moves from a high point to a low point and spins a turbine to generate electricity.
Expanding on the generator suggestion, I think you should use it to power the LEDs in a Lego House
This is so funny!
Here's a good video idea: See if you can make power tools using LEGO! Like a drill or something...
