In this project I will be showing you how to create a simple driver circuit for a 113kHz ultrasonic piezoelectric disc. The circuit basically consists of a 555 timer circuit, a MOSFET and a couple of complementary components. Along the way I will also show you how the commercial product works. Let's get started!

@MayorOfTexas 3 года назад

The capacitor missing from the schematic seems to be a 100nF ceramic capacitor that should go from pin 8 on the NE555 to ground. Without that, the square wave the NE555 produces has a high voltage peak at the start of the wave.

@TheDradge 3 года назад

I looked on ebay for some piezo resonators to experiment with them and I saw the 113KHz item in your video but also noticed resonators marked as having a frequency of 108KHz. Perhaps the commercial unit is deliberately marked incorrectly and the output of the microcontroller with the lower frequency you measured is correct. Perhaps you can devise an experiment to find what frequency gives the highest output rather than having a preconceived notion of what the frequency should be. This would be a better way anyway as you'd expect some tolerance between different resonators and you can fine tune them somehow. Maybe a circuit with a PLL could be self correcting so it produces the highest output by tweaking the VCO on the fly? I'm sure that alone would make a great video with your talents!

@paulhamacher773 5 лет назад

So you may not submerge this new piezo disc under water in order to function? That would mean it needs a very precise waterlevel, which continuously decreases as the piezo creates mist from it. How do commercial mistmakers deal with that problem?

@raykent3211 5 лет назад

This might be a possibility. Float the disc on the surface, maybe at angle if that helps. You'd need a "raft" and very flexible wire.

this apparently raises a new problem: you have to ensure, that the piezo is alway correct positioned to the water level. it can only run for a short amount of time, because the water gets consumed and we have no way to adjust its position... interesting problem...

Any suggestions? My other try with a readymade ne555 circuit hooked up to an irfz44n just seems to catch fire (/the mosfet gets so hot surrounding wires melt), but it works....^^'

@GRBtutorials 5 лет назад

@@greatscottlab Yeah, Dave has recently made three videos about that 3 cent MCU. Impressive!

@goosenp 5 лет назад

@GreatScott! @northshorepx The cheap microcontrollers need less support components, so if it means one capacitor or resistor less it might work out cheaper at high volume. Given less support components outside, such as a capacitor which might have a big tolerance such as 10 or even 20% error (maybe even more if you go cheap), you are also less likely to have defects on the production line, since if they went with cheap passive components and the 555 route the timings might vary greatly between them. While the video did show it not being exactly the resonant frequency (though it might have been an intentional design choice), the internal RC oscillator in modern microcontrollers have become quite good and I would trust it a bit more than an analog solution when cheaping out on passive components.

It is not efficient. 4- Did you think that the Frequency setting you made without load would change when loaded?
