is this circuit applicable on multiple fans?
Amazing my friend..new friend here watching..giving my full support..
Really i will do this..
Good idea. Very useful
Nice work..
Max volt ?
i want make speed control for 4 12 v fans ..... is it possible ??
How for 60v dc fan?
What about on off indicater. Can you show
which power supply use
Dc
When i give a vcc BD139 start heatup and burned....why.....
Any solution
Me too. Luckily I tried this with 12v battery and didn't leave it running for too long. Lost 10k and 100k Pot to this. Did you turn your pot to far end to check if your fan can slow down to the point of stop spinning? That is what happened to me. If you did the same, we can assume that this is fire hazard. It should be used for experiment only.
Always install heatsink in bd139 and d88x series
3 fan run in one dimer possible ??
without heatshink it can burn 100%
Wait can you make 3 speeds using the potentimeter
probably not like you’re thinking… the pot shown here does not have the “click” stops like a typical 3 speed fan switch.
@@brucerulz5297 Yea that's impossible .
what is the rpm?
Kya hm...Isse controller se 2 fan ke speed control kr skte Hai.....? Main Dono fan ko 24 volt dunga
can't we control the speed if we only use potentiometer ? . why we need other devices
i want to know this too
Depends on the fan and the potentiometer. A 1.0 watt rated potentiometer would work fine on a 0.5 watt fan without the transistor. if the fan power is higher than the potentiometer rating you can get smoke out of the pot.
Con un 100k di control che componenti bisogna mettere? Grazie.
identici.
Ya hice uno con un 317, aguanta más amperaje
Kiya B50K use kr saktay hain 47K ki jaga?
Mein ne ye banaya hai pr fan chal nhi rha aur jb hath se ghumaowo to chalna start ho jata hai pr boht zaiyada hi slow hai
I mostly got all of it but my fan is like so small
Good idea,, Sir,, Thanks
Bro it will increase voltage also?
doesnt work...
I have a different potentiometer than yours it's from a speaker I has a capacitor ,transformer and more
sir , ihave this background music
please link
Please don't solder like this! Cold solder joints like these in this video, are not going to last.
Dc to ac 220 v ???
I didnt understand how does it works?
Nice, very good!
BD138 get heated
Instead you can buy a DC motor speed control

Horrendous
