Make your own Super Simple Ultrasonic Mist Maker dalek: Hi i looked at both your videos seeing this works for the lower frequency ultrasonic version here i used the idea of it and changed some parts to do the same thing on the 1. 7mhz version i am yet to test with the device BUT circuit works good. so its pretty much the same idea but i use a LTC1799 as the oscillator as you can use it over a wide range of these devices, i wanted it for the 1, 7 Mhz version and later on for a 3mhz one any way i feed that 1. 7mhz square wave to a Bu2525AF npn power transistor and the inductor is a. 03mH showing 1. 8ohm. the LTC1799 is 5volts and at the moment the transistor has a 12 volt supply and waveform increase's with voltage here i could go up to 1000 v if i wanted. i am also interested in vibrating Quartz Crystals and you need a few hundred volts to do the same thing as the device used here. i used that transistor as it runs very cool and works well. i will post a link here in the future when i start doing tests. but thanks for your work as it sure helped me. BTW the out put at the inductor is a clean sinewave spot on for the device.

GreatScott! On your Instructables page you show 10 components, yet in the parts list and schematic you only use 9 components. One of the 4 caps in the picture of the parts list is not in the schematic but IS shown in all of the pictures as being connected in the circuit. This makes doing the project difficult as the images for it do NOT match the schematic.

I use this same circuit, I generated the required frequency, it was the same after IRFZ44N but after 100nF(1206) capacitor its value increased by 3-5 times. I need 113KHZ but at the end I m getting between 400-500KHZ. Please help if any one can understand the problem. The circuit is same as it is in this video.

i need help, i put the circuit together, input 8, 4 volts a little bit of mist and a hot mosfet, 12 volts lots of smoke from my inductor and for a short time lots of mist.
whats going on!

I needed this to finish a prototype of a product I want to put out in the market! If I ever make any money with this project I promise to become your number one patron! Love ya Scott!

I'd love to see a diy for those 40khz jewelry cleaner transducers you can buy individually from china. The pre-made drivers for them all seem pretty expensive.

Love this and think you are very smart. However I wish there was a way to supersize the result. Do they make larger discs that would result in more fog?

Thanks, This video is very useful. Can you please make a circuit to drive 1. 77MHz frequency piezoelectric element Please.
Thank u very much.

reply

If only a signal with resonant frequency is required. can we use an Arduino and a MOSFET driver to supply the frequency to the piezoelectric disc?

COOL! Next Halloween Challenge: MASSIVE fogging INDUSTRIAL MIST MAKER with multiple piezos.
Have you seen those at Ali? That must be insane! XD
