See my latest experiments and behind-the-scenes footage!
Can you power your phone using a generator made of Lego? What about a homemade Lego speaker? Let’s find out!
I’ve made a lot of generators in my time. Many of them have been silly DIY experiments and don’t output much electrical energy. But this time, I wanted to make a simple generator made of Lego that is actually useful - powerful enough to help during a power cut, and compact enough to take anywhere for emergencies.
This Lego gadget is simple enough for anyone to make if you have some magnets and copper wire.

You could add a joule thief circuit to output a steady voltage. this kind of circuit is used in shaking torches and is designed to be used with coils in generator circuits.

@trevorhaddox6884 Год назад

You can probably increase the efficiency by using electromagnets instead of permanent magnets like real generators use. You'd need to make lego brushes and use either use a magnet generator like this one on the same shaft or a feedback circuit to power the coils.

@JamiesBrickJams Год назад

I would absolutely love to try building a self-exciting generator using electromagnets, but still need to do a lot more reading on how to get it to work (and to start and control when it's running). Cool idea, cheers for the suggestion!

With two or more lego rings from the speakers, a good amount of strong big or small magnet blocks and coil arrangement... a well designed shaft or bushing levitating system for decrease friction... A flywheel.... and a good detachable gearbox... Could end up on a really and powerful selfmade lego generator! With a vertical helical cardboard or papper propeller in the end could work as a Vertical axis wind turbines? If it works and isnt expensive, I would try to make one too X)

Definitely going to try making either a vertical or horizontal turbine generator! Already had some promising experiments - I'd definitely encourage you to try your own if you're interested in this stuff. If expense is an issue, other home materials work great!

@JamiesBrickJams Год назад

@ekalyvio 10 месяцев назад

You need 2 cheap things to make it more efficient than that. The first one is a full bridge rectifier that takes the negative part of the AC voltage the reverses it to make it a kind of DC voltage. You can implement such kind of rectifier with 4 simple diodes if you search on internet. Then at the output of the rectifier you need a capacitor in order to smooth the voltage and make it stable. You will see that the leds will stop blinking and it will be producing more stable voltage.

@JamiesBrickJams 10 месяцев назад

Yup, later in the video those are the exact things I used to power the speaker and phone. The small block with pins was the full bridge rectifier and the capacitor bank was used to smooth the output!

@mihaipuscasu7357 9 месяцев назад

Now you only need to create a gravity battery and hook it to the crank, and you're sorted. Will have to figure out the proper gearing and a way to stop the weight from accelerating beyond a certain point, but I'm sure you'll sort it.

@JamiesBrickJams 9 месяцев назад

Love the way you think! I've actually already made one - using an escapement (tick tock) to slow the feed, and a big magnet as the pendulum. Love the idea of gravity batteries - thanks for the suggestion!

@platinum2522 8 месяцев назад

you should hook up a weight and pully system so that you can convert kinetic energy into rotational energy, with a high enough gear ratio that it takes hours for the weight to fall, and keeps spinning the magnets. you can also put in an old timey lathe pedal so you can lift the weight without manually cranking

@JamiesBrickJams 8 месяцев назад

Oooh a foot pedal is a great idea, I'll definitely look into that - thanks! As for a gravity drive, I've actually already got something like that working. It's real tough to get it to run for a significant period of time though as you're limited by the physical robustness of Lego. But several minutes is possible. In fact I have a video coming out in a day or two that borrows a similar principle using a pendulum 😉

@brysgohanfan8387 9 месяцев назад

Add a gearbox to lower the amount of rotations you need on the handle to make the magnets spin even quicker

@JamiesBrickJams 9 месяцев назад

Can do if a device needs higher voltages! Though for lower voltage devices, the losses in efficiency with higher gear ratios tend to make it perform significantly worse

@JamiesBrickJams 9 месяцев назад

I see where you're going with that theory. However that's the common 'perpetual motion machine' proposal, and it breaks the fundamental law of conservation of energy. Essentially what will happen is that energy is lost to its surroundings. So when you crank the handle, although some electricity will be generated, much of the energy will be lost to mechanical friction, sound, heat, etc. And so the amount generated will be smaller than what would be needed to feed the motor to turn it. In fact in this case, my generator is VERY inefficient. Motors generally require massive current to drive them. Mine really doesn't output much

Yep, the gearing causes efficiency loss to friction and heat. That's why I stressed that less gearing is preferable, as this is where your efficiency loss comes from. In an ideal world, you'd have no gearing, and would tailor the number of coil windings to generate the approximate voltage you need at a given speed
