Happy making 😇😇😇 And do share the video on Instagram (@techiesms) once you make this project

I am using ac dimmer for Controling fan speed and it working perfectly, no humming sound. I made the circuit from one of your tutorials and order it from jlc PCB. Thank you for all the simple and smart ideas.

[@techiesms]

Humming sound comes when your fan is running at slow speed

Great work in reverse engineering a fan dimmer, but it would be simpler to use a Triac for Dimming application and the circuit would be smaller and cost efficient aswell..

Nice one 👍 My alternate idea is to attach a cheap servo (sg90)on top of the regulator. There by you don't disturb the existing connection.

Thanks for shared. Kindly confirm with capacitor type ok with fan speed regulator. Polyester capacitor or Polypropylene capacitor?

[@trego9584]

Great Job-like always I love all the work you do. There is one thing that you need to add that is a box to install the relays in and some type of shielded cable for all the mains voltage. None of the higher voltage terminals or wires can be exposed

For a 4 speed control fan regulator, we need 3 switching circuits. Hence 3 relays,

Such a ginormous fan regulator. This looks like overkill. But it can be a nice Juggad thing for learners and hobbyists. There are many other ways to get hum reduced out of these fan regulator circuit using proper methods. Anyways your explanation presentation is good! keep it up.👍👍👍

[@Crestpak1]

I need some clarification, as you say that point 3 is connected to point 1 and point 2 it means all 3 points are shorted, in that case either we select point 1, 2 or 3 path of electricity will remain same as the electricity will flow from a common node to all paths

Awesome idea. This video was also very informative like your other videos. One drawback is this is bulky. My sugestions, the same thing can be achieved using 2 relays also. Fix it on a custom made PCB to make it smaller.

You should have used "STEP WIDGET" instead of slider. That would have made sense as the regular fan regulator has steps to control the speed.

Bro what if we want two way control, so we can use potentiometer as input for esp at three different pins in order to give it the desired level of speed . But how to give it preference over the blink controlled...? Any help...

@@techiesms thank you bro, but I was asking about the preference as you made the light switch , so consider this that i want the physical potentiometer to be the master switch and its values to be reflected in the app and the app to be the secondary switch . I understand the working and all but i just can't realize how to make physical switch a preference . So it will be very good of you if you explain the code as well. Thank you 😊

You need to find a way to put software speed control in this order, OFF>>High(4)>>Mid(3)>>MidLow(2)>>Low(1) or there's gonna be fan coil damage or something like that.. the regulator u tore apart should also be in this order.. Or Make sure Fan is at highest speed while turning on

I want to use button -1 as Fan start and stop By using button When the power is off, after coming the power the last function should be stored in eeprom

Hey Sachin, this is great explanation and very well presented. I have been running similar setup for more than a year except with D1 mini board and ESPHome firmware - it has been a rock solid. Like you presented, I did use the existing regulator board by removing the rotary switch and soldering wires which go to relay board. I'm facing hard time finding these capacitors. Do you know from where can we buy the capacitors separately? On a side note, I also tried to design custom PCB with two big capacitors and 3 relays to make it compact but didn't order as unable to find the capacitors. I shared PCB renders to you via email last week which includes this board. Do you happen to see that?
