good for educational purpose but for use you can put led in that aluminium end it may work as reflector and a switch with supercap to store for some time and use after
TechnoWizard - Great point! Why not make the whole rectifier bridge out of LEDs? That way all of the power gets converted to light and no passive components are required to protect the capacitor. I'd still want a switch though.
@@rolliebca WOW! Excellent comment! 👍 That is a brilliant yet simple idea to make the 4-diode full-wave bridge rectifier out of LEDS. That way, you kill two birds with one stone, and you save $$$$ on parts count!
using a super capacitor and a single diode you could simplify it hugely and you would reduce your voltage drop over the diodes. also adding a longer tube and springs at the end you conserve more energy and the system becomes more efficient. there is a formula for working out the ultimate speed and length of travel. helps to know the strength of the magnet and making a magnetometer would be another great project, there is a great instructable for building one with a nano and hall effect sensor. by tuning the system you can get peak performance where a few shakes will last a long time. full bridge is wasted with a single led load. work out the output and up the diode to the right wattage and get the best bang for buck. its a simple project that would be a fun series of videos.
I'd rather use a crank and look like I'm fishing rather than using one of these and be looking like I'm jerkin the turkey. (Just a joke. Good video like always)
Help with this please.... I have this set up with PVC but it is not working. I am using non insulated braided copper wire instead of insulated copper wire. Is that why it is not working? Or is there something else? Thx in advance!
If you put a magnet with counter poles on each end, the magnet inside will remain in a dampening magnetic field and won't bump against each end of the tube. This also makes it more quiet :) Saves you schok cushions or springs on each end.
Hello LS, Very cool, I had store bought version, it worked good. Nice build on the light. You always have something of interest. Have you done any sound to light projects, the LED reacts to music, a clap, etc.. Google a schematic on images. Happy Year End, all the best from Oregon, USA, C.
The LED flashes in both directions because: when the magnet goes left to right, the magnets field is directly responsible for inducing a current in the correct polarity for the LED; when the magnet goes right to left, the magnets field imparts energy to the coil which is in reverse polarity to the LED, but as the magnet exits the field collapses in the coil which causes a reverse direction voltage spike, it is this that lights up the LED
Can you use any capacitor or does that affect how strong your magnets need to be and/or turns for voltage? It's a positive voltage all thats needed? Would 1 volt fill it all eventually?
it can be done 10 times better with less parts. one end of the coil goes to a pair of diodes opposite to eachother. the other end goes to 2 capacitors in series. you connect the diodes to the capacitors and you get a voltage doubler. this way you loose far less energy on diode voltage drop

COIL MAKE Back EMP ..... this why led flash in both direction.
When the magnet travels through the coil, it creates one full period of AC. That's the reason why the LED lights up in both directions.
thanks!

The LED is itself a diode, so it's possible the rectifier diodes may not be needed - except a diode to protect the electrolytic capacitor
I think he (Mr Ludic) was taking a risk of zapping the LED. He should play it safe and use diodes with the LED.

Also you can add joulethief to use more energy from the suppercap down to around 0.5volts, not only the 2 or 3 volts the led required.
I love your, Science Project videos buddy 👍🏻. You really make even the Community located Science projects look, Easy to make 🙌🧡👍🏻.

Sounds like you’re cranky
An elastic band you wind and it unwinds to make power as the magnet spins. Because it bounces inside as you walk it keeps it charged.
Mr Ludic, why didn't you use supercaps in the video so that the LEDs light up longer?
FULL BRIDGE RECTIFIER
Nice work bro!
Seems reliable!
Seems we had the same strange discovery at about ~ the same time , thanks for sharing

Well done. I had made syringe generator like the same way. Now I am able to make dc torch using bridge rectifier. Thank you Ludic sir.
Thank you, very useful might use this for my project 😁

I think you're right. Not sure, but I think the direction of the induced current reverses at the mid point of travel
Bro this is the best explanation so far.
Can u please do the experiment with super capacitor
Look for greatscott version of this video
The LED illuminates in both directions due to the collapsing field voltage of the coil.
Just use a Super Caps ! So you can stores more Power
Shake it like a Polaroid picture
Can you use any capacitor or does that affect how strong your magnets need to be and/or turns for voltage? It's a positive voltage all thats needed? Would 1 volt fill it all eventually?
what will happen if i use ferrite magnet?can someone answer plss...
Good it works
Lasts forever, well a lifetime 😂
Put two spring for the great oscillation
it can be done 10 times better with less parts.
one end of the coil goes to a pair of diodes opposite to eachother. the other end goes to 2 capacitors in series. you connect the diodes to the capacitors and you get a voltage doubler. this way you loose far less energy on diode voltage drop

What if we add a joul thief in this‽
That's what I thought (Joule Thief) + a Supercapacitor as well. Then we can have long-lasting light with a few shakes.
Watch the greatscott version of this flashlight he did the same
Germanium diodes with their lower voltage drop would be useful here.
Use a resistor to the led...then the capacitor will discharge slowly...
And then the led will glow longer...
#NewCrazyExperiment
I want to see with super caper capacitor as well
That’s super duper buddy
Genius
Always unbelievable
Nice Flash light Following the, Faraday's Law of Magnetic Induction 👍🙂.
did you upgrade the canon ?
not yet
Trimakasih karna membuat senter tenaga magnet tapi bisa tidak pakai elko tapi menggunakan batrai 3,7voll
Awesome
Nice one.
Requesting you to make some levitation circuit project
😂😂😂😂👍👍👍
👍👍👍👍
I had made this yrs ago
Who cares, show-off? Come here just to tell your achievements as if you were better? How arrogant you are.
