You're welcome! Yeah nowadays everyone just slaps a microcontroller into everything, be it only for the sake of saying it's digital... But I find many times the joy comes from the simplest of things - the more minimalist I can design a circuit with standard components that still does everything it's supposed to do the better!

Sehr schönes Video. Mir gefällt persönlich, dass du genu das mit zeigtst, was beim Basteln, des öfteren passiert. Es funktioniert nicht sofort. Fehlersuche ist angesagt. Gerade wenn man keine Professionelle Leiterplatte verwendet, kommt es einfach vor, dass man irgendwo eine Drahtbrücke vergisst, oder ähnliches. Meisstens ist der Fehler schnell gefunden und behoben, aber manchmal sucht man sich dumm und dämlich. Zum schluss fehlt einfach, irgendwo die Masse an einem Bauteil. So macht jeder seine eigenen Erfahrungen und lernt. 😉
I used a s9014 instead of a 2n222 and p80nf55 in the place of an N-channel mosfet but when i hook up the power (12 volts from a PSU) , it draws so much current the the mosfet heats up and the pwm doesn't work. when I hook up a 9v battery and i put the output wires in my tongue and i crank the potentiometer, I can feel current but when i hook up an led or a motor, it doesnt seem to work. Help
In the video my MOSFET got pretty hot at first as well, there were some connections I should've removed. Nine times out of ten when a breadboard circuit doesn't work, it's just a wiring mistake. Take it apart and put it back together from scratch, then it should work (unless you did the same mistake again). Just recently I tried putting together a high voltage programmer for AVR programming and it didn't work. Turns out I had just forgotten a jumper and after reassembling it everything worked fine. Your component choice should be okay. Also, there is a newer version of this circuit you might want to try: ruclips.net/video/CcMiGZUzITo/видео.html
did you set a Rb resistor for the Darlington? Rb = (Vin - Vbe)/Ib where Ib = Ic/ hFE. It is important since it determines the saturation and so that the transistor acts as a switch
Since it's a MOSFET I didn't calculate anything 🤣 the 100k is just an arbitrary value, should even work without one entirely. Just the ratio between gate resistor & pulldown resistor should stay roughly the same. Worth noting is, that both values shouldn't be too small, or it will stop working, since it is essential to not disrupt the MV's operation, by lopsidedly draining lots of collector current. That's actually the only reason for using a MOSFET at all.
I had tried using a transistor off camera, and it didn't work out. A few weeks ago I tried again for another project, and came to the conclusion that it probably is possible, but only by adding like 5 more transistors to form a schmitt trigger and other stuff to get enough amplification. For some reason the transistors just won't turn on and off properly if I just use a darlington configuration.
The 4.7k resistor connects to the middle pin of the potentiometer (the wiper / output) I also developed a new and improved version of this circuit a while ago which I strongly recommend to build instead of the one shown in this video. It's very similar but gives better results: ruclips.net/video/CcMiGZUzITo/видео.html Schematics for several versions of this circuit are free to download in the description :)
At last someone who knows what he does and shares hes knowledge also to others, and do it for free too! 👌 Because 555 is too ecpencive and too ic to use on that!

Darn, just after finishing the video I realized that I had forgotten to put an LED on the final circuit board!
Hehehe
Genau solche kleinen Fehler passieren und machen einem das Leben (den Erfolg) schwer. 🤣
Honestly dude, this is really really helpful
Thx
That's good, I wanted it to be helpful!
I love the use of t0-92 transistors, many people avoid their use, even in cases they work better!
Thanks for the efforts making this video!

I totally agree, and it's just easier I feel. You've just inspired me to do my pt. 3 video on no coding rotary encoders. Cheers mate!
@@arenotdiy great!

What a lot of help! Other videos I found not as good. Now no need to buy expensive ESC's!!!!😉
I'm actually revisiting this with a better version that uses only transistors :)
@@ChronicMechatronic great!!!

@@ChronicMechatronic Thanks for the feedback. I’ll do as you said
great explanation!
Where I connect a potentiometer if I want to?
how to make inverter with it?
Can you use a 10 k pot instead of 100k ?
The new and improved version uses 10K: ruclips.net/video/CcMiGZUzITo/видео.html
@@ChronicMechatronic thanks it turns out i burned my 100k pot so this was another good circuit
One reason for using the 555 is that it will 'always' work. MVs, apparently, maynot start. A fuse might be a good idea if the motor stalls.
Yeah, a fuse couldn't hurt... Though I've never seen an instance where the MV didn't start.
Sir What all electronics books you referred for the basic knowledge of electronics , pdf do you have
I don't have a book I'd recommend, in fact I collected my knowledge from many different sources, primarily youtube
Hey dude , update , how can i contact you? I tried it didn't work , i chose this as my analog project and now um..
where are your country
I live in France
Hey dude, it's me again, I've completed it and i seem to get the same chronic error you're getting, could you help me out

@@ChronicMechatronic Maybe I got it wrong but I had thought at the end you had tried using a BJT.
@@ChronicMechatronic One caution about MosFets is that they need a relatively high input voltage - it depends on the Vgs[on] parameter
I had tried using a transistor off camera, and it didn't work out. A few weeks ago I tried again for another project, and came to the conclusion that it probably is possible, but only by adding like 5 more transistors to form a schmitt trigger and other stuff to get enough amplification.
For some reason the transistors just won't turn on and off properly if I just use a darlington configuration.
Yeah, that's just what makes it work In that circuit.
I don't trust anyone who doesn't have a hidden container of at least two dozen 555 timers hidden somewhere in their home for unforeseen emergencies.
Well in that case you clearly can't trust me since I only have 3 single 555s in my collection - and I never had an emergency that required a 555 ;p
Wow thank you sir i need that
Can I use IRFZ44N 😀
Yep, as far as I can figure! I think every N-channel MOSFET with a gate threshold voltage below 5V should do 😄👍
I've searched on google it says 49 amp to drain and gate threshold voltage is 4 volt, I'm gonna make this circuit, thanks for this circuit👍😀.
@@avaydon7679 yeah, I looked at the datasheet as well before telling you you could use it. 😄
that is a linear pot, right?
Yep it is.
Salvaged.
Bro. You made a very nice video
But i could not understand how you connected 4.7k to 47k in center
Please make me correct
The 4.7k resistor connects to the middle pin of the potentiometer (the wiper / output)

Who saw the explosion at the end?
Hehe I did😉
given the 640 is a counterfeit part (batch code 77 WS is most used) be no surprise. lol. nicely done sir none the less.
@@commonsenseisdeadin2024 haha 😂
Now you talkin 👍😎😀
😆
This thing was actually the sound generator in my last short 😂
Yeah, this one is awesome😀
Nice👍💖
As i already expected, the old two transistor multivib😁
There's a better version coming soon!
@@ChronicMechatronic oh i did not mean it as criticism. On the contrary, an old and tested and sturdy design
No, no, I didn't take it as criticism 😆 I just wanted to say that there's actually an even better solution, I'm currently working on the video :)
Bro can you make a drone with arduino
Not yet sorry, I'm pretty bad at coding - the video I'm working on right now requires an Arduino, you'll see.
At last someone who knows what he does and shares hes knowledge also to others, and do it for free too! 👌 Because 555 is too ecpencive and too ic to use on that!
a 1N4002 diode should suffice
Probably, I just used what I had lying about.
so funny
