Simple and beautiful project, thanks for sharing it with us. As a request I would like to ask you that if you can leave us a small diagram, drawing or photo of how you made the connections of each component in the copper layer? … many of us can not read and understand the circuits well and ended with committing errors when I connect and weld the components.
could i use a 1Mohm potentiometer?
220mf in description and 103 mf in diagram ? Which one tell me sir
bro..! En el esquema no viene el capacitor electrolitico, donde va conectado y de que valor es..?
Can you make an video over mechanical pedal washing machine.. on principal of Niel kerns washing machine
update your schematic man its wrong to the video or components you've mentioned
This circuit is using MJE3055T a Bipolar Power Transistor, NPN, 10 A, 60 V, 75 Watt.
Just if anyone wondering.
Bro can you send me this circuit PCB layout
Eine gute Sache
Can I use 12 volt led strip , with 12 v input ?
I love the 555 for pwm dimming of a constant current regulation chip. I built, hoping to incorporate into a single 18650 small tube light. The cost for parts from DigiKey was $29. I built one on breadboard and not on board. I concluded that I could make it to the 1cm cubed specification needed to fit a practical space. Come on, I thought, it is 2016, and no out of the box 1 cm3 chip yet? Plus, electronic parts are now impossible to get locally. So, I can't get a single cell light with acceptable regulation that meets the needs. The LT8500 chip looks like it might work for $6, but only a EE graduate with 5 years of experience in the field of Texas instruments could understand the wiring and pdf. A bit of overkill too, but only chip I could dig up outside of the 555…..may be someday I will attempt again to build it, and next time, shrink the size to a 1cm by 1 cm square, cube. Plus dimming probably use led supply pot for size. I am trying to control 2 or 3x amc7135, no more. Probably, 700 ma max, since the extra AMC adds only %20 to perception, but steals a huge amount of runtime, and generates, like, double the heat. . At about 560 ma and under, the heat from a 202 lpw led, is minimal. But go from 560 ma to 700 ma, and you get little gain, but a huge increase in the heat.
Sound is.??
Can i used in coil heat
Hi, do you know how high is the frequency?
please send solution
i want to make 100 watt led flood light dimmet haw can it made
i want to use this circuit to dim 10 high power 3w led's with forward voltage of 3.4v~3.6v each and forward current 600mA-650mA what modifications should i do
Wonderful Electronic channel I have ever seen !!!, Bhai ek Facecam video bhi bana de !
Bro what is the minimum input voltage?
SUPER GREAT NICE
Hi sir. M n is circuit ka bldc fan ka dimmer bana kar use kiya to ic burn ho gyi. Lekin brush motor ko oprate kar raha hai. Why. Plz reply
show the connections
