This is a "poor man's magnetostrictive transducer" we used 35 years ago, when ferrite rods were available. The magnetic bias ideally must be tuned to get the most of striction, and the ferrite may be hanged/glued in the center where the motion is zero. Then tune it to the resonant frequency... Note that too much energy will result in overheating and cracking the rod. And of course, nickel laminate (if available) will work better.
To increase the vibration, you need to: 1. put a driver for the transistor gate (special microcircuits) on the gates of the transistors. 2. Reduce the number of coil turns. 3. Try to install the ferrite not so hard in the coil frame
Hi Artem. I will manage to get a mosfet gate driver circuit soon. I will try to reduce the number of coil too .. Can I use higher voltage to increase the vibration? I was planning to increase the coil voltage and use a higher voltage rating MOSFET.
Nope.. don't increase the voltage to much. The ferrite instantly crack on supply voltage around 20 volt. Increasing voltage is a bad idea Already tried the idea this morning..
I hadn't thought of using a ferrite rod that way. I made a speaker out of one of those cans that dry asian noodles come in. After a bit I noticed a warm feeling and found a puddle of plastic in my lap where the lid had melted. (I was using the lid to retain the coil against the steel bottom of the can. Lucky for me no burns and the speaker actually worked pretty well if I didn't leave it on for long.
Very good job Please tray to brake water molecules in HHO with resonated frequency . may be after when mist make Posible after mist it pass through hole of another coil with different frequency that brake stream molecules.
Saya ingin bertanya, jika jenis tranducer piezo sperti pada ultrasound therapy, signal apa yg dibutuhkan pada gate mosfet? Apakah signal kotak atau signal sinus? Saya sudah mencoba dengan signal kotak tetapi tidak membuahkan hasil.
I need some references about this build. I tried to make a larger versions of this to create a liquid homogenizer (ultrasonic mixing equipment) Any clue, books, research articles would be appreciated. Thanks. Andrian.
O finalmente qualcuno che fa qualcosa di nuovo ed interessante per gli obbisti. Per caso hai anche un circuito per generare i segnali che servono. Grazie.....
Ciao Antonio, secondo me con un 555 si potrebbe fare, poi sarebbe raccomandabile anche una rete RC in parallelo al mosfet per non farlo soffrire troppo a causa dei picchi di tensione che derivano dall'induttanza
Would it work if I applied 5 volt amplitude from the signal generator to the IRL3103 gate? My function generator is not capable to deliver 10.5 Volt amplitude. Any helps would be greatly appreciated. Thanks
The output of the generator must be powerful enough to charge-discharge the gate of the transistor.If it doesn't work well with the irl3103 transistor, try another logic-level transistor, especially the one with the smallest gate capacitance.Perhaps such a transistor will work well with 5 volts of signal
@artem : thanks for replying my question 🙂 well, I was planning to use cheap eBay XR2206 signal generator. Currently, i have no idea about the generator performance to charge and discharge the mosfet gates.. Btw, would it work if I use a mosfet driver to drive the gates? How about the TC4420 mosfet driver?
Hi again. It's me again 🙂 hopefully you will reply me again this time 🙂 I managed to buy a signal generator FY3200 which could give amplitude in 10.50 volt. I tried to replicate your experiment, with same parameters such as: 1. Using same transistor (irl3103) 2. Using same ferrite length (8 cm) and diameter (8 mm) 3. Using exactly same wiring arrangement 4. Using same wire diameter (8mm) to make coil (90 turn) on the ferrite 5. Using frequency around 35 kHz and amplitude 10.50 volt to drive transistor 6. And using 16 volt to the coil After much trials, I can't see any vibration on my ferrite. I also tried to changing the frequency values, and the height of ferrite to the magnet, but nothing is happen 😔 can you help me solve this? Thanks,
Btw.. how you can find the best match frequency value for the device... I was so tired after trying to tune the frequency by rotating the signal generator knob Do you have any special or specific method to do it? Can I use sweep frequency feature on the signal generator to figure out the best match value? Oh .. One more.. My MOSFET is instantly fried on values around 10KhZ.. I heard hissing sound, and then the mosfet is extremely hot (already used aluminium heatsink). The current rise to about 1.5 ampere. After that, I realize that my MOSFET already died 😂
@@alexa.davronov1537 thanks Alex for your reply.. i really appreciate it. I was spend my saving to buy the signal generator. But unfortunately it wasn't working as expected.. I will try your suggestions Alex. Thanks.
@@alexa.davronov1537 The ferrite were vibrating now 🙂 the problem is: 1. The coil winding direction are very important. the ferrite start to vibrating when I swap the direction of current. if the direction are wrong, nothing happens. 2. To find the correct frequency, you can use sweep mode on your signal generator. Because resonance frequency is really f**cking specific value. my ferrite is vibrating only on about 31700 Hz - 31800 Hz. I also found that the frequency only influenced by the dimensions of ferrite. 3. the single irl3103 mosfet is really hot. I managed to use set of 2 power MOSFET 70n06. After using multiple MOSFET, the overheating problem SOLVED 🙂. Be aware to use 47 ohm resistor on each gate of the mosfet if you using multiple MOSFET. But the vibration is not strong enough for me.. is anything I could do to improve the vibration..
We have all this technology spoken word goes a long way I really wish that people could make these videos and speak while making them and verbally tell us what you're doing you'll get more clicks more people will watch your video and it's way more informative Charlie Chaplin died a long time ago and so did silent movies nevertheless thank you it is appreciated

Hello amazing video ! I want to know if you can generate infrasound with this ? For a sonar i need to produce 1hz to 20 hz to reach a distance of 5 meter maybe more .
@@Hudsonkem Ofcourse we gonna have to use wave generator. wave generator will control the gate of the mosfet. wave generator -> mosfet -> amplified signal wave generator doesnt generate enough power to kick the coil. The generator will control the gate of the mosfet, hence the power will be amplified by the mosfet. The mosfet would switching on and off according to the signal from the wave generator, hence you can get a larger power capacity. you better watch the video carefully 😊
YOU CAN USE A PULSE GENERATOR 1HZ~150KHZ Signal Generator 3.3-30V PWM Pulse Square Wave Frequency Generator would put a bridge(H-Bridge) with push pull which you can adjust to the output of the generator TIP142 and TIP147 are preferred

What you created was a machine to use hysteresis to heat metal. That’s what I’m after. This is in the realm of blacksmiths.
the subs for the circuit really showed me i truly am in the future
Amazing! Does the ferrite rod need to be tuned to a matching frequency or does it work over a wide range? I assume it needs to be quite small
Super! Beatiful! Thank you very much for genial idea!
How cool is that ! Your chanel is so underrated!
One question , why not Electromagnetic transducer used in place of pizo martial in some application like US cleaner etc ?
Very good job
Please tray to brake water molecules in HHO with resonated frequency . may be after when mist make
Posible after mist it pass through hole of another coil with different frequency that brake stream molecules.
Ye black stick kya h
What frequency you are operating at 10k
And what's the voltage ??

Is it safe to put water droplets on any ultrasonic transducer?
Could you please show the exact details of the actual circuit？
So cool!!
Thank you I like you
excelente!!!
What is the maximum limit of electromagnetic Ultrasound frequency ?
There is no limit. But practically around 1 megahertz.
I hate computer chairs 🤣 nice build 👌
Wow water test is amazing
Can it work above 1Mhz frequency ?
I need some references about this build. I tried to make a larger versions of this to create a liquid homogenizer (ultrasonic mixing equipment)

Its core is Ferrit right? And where can I buy it?
yes, not sure.
Hello, can you please tell me how much is the voltage and Amper?
14 b =v
I think the schematic said 500mA and 14V
