Nice👍 bro.
@Android Solve thank you 😊
You brings always new inovative projects. :)
@@ankurchauhan1966 haha thanks again 😁
@@Creativecreator some people like me already know this project and how this works
If anyone is curious, he is using the capacitor to maitain a voltage level on the gate to put the mosfet into semi conductance mode. The biggest problem with this is it will dissipate a huge amount of heat depending on the load and will probably burn out with larger loads. The charge level will also drain away and will not be "constant", so this is just a basic hack using the near infinite resistance of a mosfet gate.
Thanks for the info . How about a bigger capacitor ??
@@UserUser-ww2nj ,,?
@@UserUser-ww2nj Larger electrolytic caps usually lose charge over time by themselves. And using them won't change linear mode of operation of the mosfet. Meaning it will keep overheating. Note that with the last LED on the video you can't see a transistor. Probably because it is a different one and/or with a big radiator.
You're right, when you say that *...the charge level will also drain away and will not be "constant"* !... But the charge level will be kept longer if you use (instead of a 1 μF / 250 V polyester capacitor) a 4.7 μF / 25 V eletrolytic capacitor. But be careful with its polarity (don't forget it's a polarity-sensitive capacitor) !...
Gracia 👍
Pressing both switches simultaneously creates a short circuit between Vcc to Ground. An alternative is to put an additional limiting resistor (at least 1K) in one of the switches although this would slightly slow down either the capacitor charge or the discharge (depending on which switch is chosen High or Low).
A symmetric response protected circuit could be made with two 1M resistors, each connected to the respective switch and then both to the capacitor.
ua-cam.com/video/RAA42bzYnGk/v-deo.html
ua-cam.com/video/xXmgRCfeMro/v-deo.html
The problem is when both keys are pressed.
A short circuit occurs, the keys burn out.
Be sure to add 100 ohms to the row of keys.
First resistor from + to first button.
Second resistor from - to second key.
And there is an other solution for the problem of burning out the keys: instead of using one single 1MΩ (one mega ohm) resistor for both microswitches, you'd better use two 1MΩ (one mega ohm) resistors (one for each switch), both connected to the MOSFET's gate.
A little tip... When bending the wires on a component, hold the wire with the pliers, and to bend the wire, hold the wire, not the component. This way, you don't put any pressure on the wire entering the component. If you bend the component against the pliers then you risk breaking the connection between the wire and the component.
Hope this helps.
Thank you 😊
I always try to hear from you guy and try to improve.
Good night friend. congratulations for your work. The circuit does not allow to activate the two switches simultaneously as it would short the source.
As a suggestion it would be better to connect a 1M resistor after each switch and connect them to the MOSFET gate.
Yes 😊
You are right ☺️
Just discovered your channel with this video, As a retired twelve year high school electronics teacher just love your techniques. I could have used this video to teach my students a ton of techniques in assembly and electronics in a few minutes. I started out life in professional video production. Your production values and timing are awesome. This is some of the best tutorial video I have ever seen. Thank you
ua-cam.com/video/RAA42bzYnGk/v-deo.html
I didn't really care what you were making because it's miles above my head. I was just fascinated with HOW you were making it. It gives me hope that, maybe, one day I'll be able to solder two wires together without needing to call the fire department. :) Thank you for the inspiration.
You will buddy.
Just Learn Create and repeat 🙂
Those wire strippers are Top 10 buys over the pandemic. Sometimes I just cut the ends of wires for fun.. I am not ashamed.
i love these videos, simple and practical way to understand basic electronics
I tried this it is working great. I used old SMPS components. Thank you so much for sharing this trick as well as the Schematics.
Glad it helped
ua-cam.com/video/RAA42bzYnGk/v-deo.html
If you build this, DON'T PUSH BOTH BUTTTONS AT THE SAME TIME. I think you'll short circuit your unprotected Li-Ion cells, and maybe cause a fire.
Better use 2 seperate resistors, one for charging and one for discharging the capacitor, then if both buttons are pressed instead current will run harmlessly through 2 resistors... and you'll even add another feature to "set 50% brightness" when both buttons are held. (Because in this case the capacitor will discharge/charge towards half of the supply voltage.)
I like the thought "what the hell is this guy building", followed aaaaaahs and oooooohs 😁
Very interesting, thank you!
Welcome 😁

A 1megaohm resistor and a 250pf telephone socket capacitor button switches LEDs and crocodile clips. And maybe two 9v batteries in series.
At last a tutorial video with soldering that doesn't drive me insane. Great work
Haha thanks 🙂
Powering a higher power load and using the fet in the linear region, the fet is going to get hot, possibly very hot, you need to add a heatsink to the fet. One other thing, show us what happens when you press both buttons at the same time,,,,,,,,battery, switch, wiring check, one of the three will fail and maybe smoke. Thanks for the schematic.

Nice circuit! It’s nice to see a simple analog design that doesn’t use a microcontroller or Raspberry Pi...
Very nice "freestyle" soldering skills. It's one thing to solder a board together where the parts are more or less captive, it's another thing to align parts in space and get good results.
Very true
Wish you explained a little more what you are doing each step so I could learn. The visual part is perfect just needs a little narration.
Check this: getvid.cc/12v-led-dimmer-with-irf3205-mosfet-and-1uf-ac-capacitor/
exactly
I think it’s more fun just watching and then researching what’s going on afterwards.
he just made a changing light from low to high probably one of the easiest things to do. imo
@@xWarPlays everything is easy when you know what you're doing...
In future projects with these small 4-pin push button switches, you might consider leaving TWO connections attached on the rigid wire supports for additional strength. That would provide two separate solder connections instead of just the one on a physical button that gets repeatedly mechanically stressed. It would reduce potential for failure of the switch electrically and mechanically.
These 4-pin push buttons usually allow you to connect two pins together for a single connection#1 and the other 2 pins together for connection#2, which increases button sensing reliability (assuming proper debouncing circutry used for mechanical switch). In this particular case you probably also could connect the switch's 4th pin to the flexible wire, if desired. Again, it adds a bit of physical strength and reliability to an electrical connection that is exposed to mechanical forces.
I doubt homeboy is going to be using this in any appreciable sense.
Friend your work is unbelievable. Congratulations!
A hug from Rio de Janeiro (January River) - Brazil
Thank you so much 😀
This is a great project, I just implemented a similar circuit when my wife's cigarette roller stopped working (some machine oil dropped onto the circuit board and fried it). It was being driven with a simple 5v DC motor, but they chose to use a 9v power supply supply (there were no resistors or MOSFETs on the original circuit board, it was just a barrel jack, a push button, and the motor). By implementing this kind of circuit and an LED indicator, it allows her to control how much current is flowing to the motor, and will hopefully help the motor last longer.
Everything from your soldering to your end product triggered me on so many levels.
Actually it's not all that bad. It's called "dead bug" construction... And with the exception of the nippy clip joints (yes that is cringe lol), the rest are fine for the construct method.
You can be triggered as you wish, but this guys soldering skills are actually quite good.
@@upravytdi thank you so much 🙂
@@upravytdi i cant imagine how bad your soldering skills are.
Soldering temp is too high. Maybe for removing the component but you shouldn't need 400C for lead-based solder. Even lead-free should be around 200C.
This is also a poor design for dimming as it can cause early failures in LEDs due to inaccuracies between the LEDs as you can see from the LED array (the 30W LED) their forward voltage varies so much that just dimming using current isn't sufficient. The correct way to dim LEDs is via PWM. That said, this circuit would be better suited to an incandescent bulb.
The reason the soldering looks bad is because the initial board for the voltage regulator was dirty, the connections look clean and I don't see any cold solder joints so I see no issue with the later soldering.
Thank you for showing the soldering techniques from start to finish . Many people forget that beginners don’t have this skill set and I know from experience that this can be very frustrating if you don’t know the little tricks that make things stick 😉. Great video

Great projects for school level children entry level, and to inculcate interest in electronics.
My suggestion as a senior in the field (senior citizen also), instead of digchik, digchik music explain the characteristic function of each component. This would help the child build an analytic thinking and design some thing on his own, rather than spoon feeding.
Схема требует доработки.Если случайно нажать обе кнопки будет короткое замыкание.Между минусовой шиной и кнопкой добавить резистор.
Ok

Interesting choice of battery pack. Never seen that type of battery before - at least not on its own, although I imagine it may be used inside of a rechargeable battery pack (at least in the USA, it's not one you'd buy at a typical store).
Just realized how mosfet working with simple video, thank you
I spent a whole semester trying to understand this lmao
@@walkerspier7751 lmaoooooo
I really like your soldering technique it looks really good
Thank you so much!!
Don't push both button switches at once! You shortcircuit the battery.
I mentioned that to the given link in the description 😁
Two resistors could be used in order not to short circuit.
@@WISELORD Don't even need 2, just one.
sooo, buttons are for charging and discharging that capacitor that feed the gate, more power to gate more power to drain and brighter leds, if you let it longer without press button for more power leds will go off. correct me if i am wrong :D
When you soldered the first leg of the capacitor I thought, that isn't a very good joint but then you soldered the other leg and came back to the first to make a good joint. Nice technique!
Thank you. 😄😄
Ok, this is legit garbage from components to the way you soldered it, but I'm gonna sub. This thing is hilarious and I've never seen something this wrong, but actually working.

That's a nice & simple voltage controller. I like your construction methods Thanks for sharing.
... Could be used to make a variable power supply, Motor speed controller, LED driver, etc.
.... so what amount of current (maximum) can it handle? Can it handle a couple of amps?
Yes it can but I suggest you to use a heatsink for higher amps. As it is a linear circuit.
nice video! I don’t think I’ve ever heard of that kind of terminal classification: Middle regulator leg is “drain” LOL

Very slick dimmer circuit, nice job. Never realized it was that simple!
Hello there! I like all your videos. If you press two buttons at once, will there be a short circuit?
Yes bro
This is the only issue of the circuit.
Later I will share a Schematics where I will show how to solve this issue with one more 10k resistor connecting with the vcc and the + switch
@@Creativecreator Just uses a single ON/OFF/ON toggle switch instead of push buttons. Then you will never be able to short circuit it. Your design is quite dangerous as you can short circuit the 3 li-ion cells directly by pressing both buttons simultaneously and risk the cells exploding and causing a fire or damaging your eyes.
Thanks for sharing. Please show us how to learn about electronic? how it all works. How to know what voltage is right for what ampearage

Thank you so much 🙂
What happens if you press both buttons at once? (walks away whistling quietly). I'd put a 10k or so resistor between them to mitigate the result of that.
I really want to know
@@thengspjo4716 Press both at once, you short the battery.
@@ian12262 ok thanks, I was actually going to build it just to push both buttons at the same time
I love the way that piece of wire just shot out of there like a rail gun lol. :... this is great it is alot like what I have been wanting to do , so can we add a volt meter and measure the voltage as it is ramped up with each click of the momentary so that we can determine the safe voltage input of random led's ( this meaning we do not know how much voltage certain led's were designed to operate at ) or field effect transformers so that we do not destroy the led in order to apply the correct resistance while we measure lumens for optimum performance ?
Isn't it a bad idea to make a virtual ground for the LEDs?
The way you were soldering was really good. I felt like i had been doing it the wrong way. Lol
I like the way he "tinned" everything before soldering - I think I learned something !

Where is the schematic diagram of that lighting control?
Push-button increase and decrease of LED intensity with only one MOSFET? That is interesting
EDIT: how long does this circuit hold the last dimming position?
And I suppose the MOSFET acts as a resistor when it lowers the power to the load.
And if you want to have nice smoke, press both buttons at the same time. ;) (Just jokeing, don't do this, this shorts out the 12 V)
@Arghadip I would rather add a second 1M Resistor. A Resistor after each switch. The star point then to the Capacitor.
Plus the fet will get hot in its linear region and will need a heatsink for the bigger led
Thank you good clear and simplified applications. I want to participate in the 2 push button connection correction. When two are working at the same time, a short circuit will occur in the power supply unit, which may cause burns and losses to batteries with relatively high current, in addition to losing part of the circuit, not all novice amateurs in particular, have sufficient knowledge of this science and the risks of errors , They only apply what is seen and this can be avoided, for example, by adding a two-way plastic slide that passes each time over the SW to make it independent of one another. Sorry - cool, keep going
Nice idea i will be adding a next version of the circuit where you can press both switches and there will not be any short circuit.

Dobry pomysł. Krokodyl w kurczliwym rękawie
Ja mam rtęciowe oświetlenie biurka na moim kanale, elektronikę również uwielbiam;)
Bro... i ran the circut for 2hrs and the full brightness led got dimmed now
It seems like the self discharge rate of this small capacitor is too much
i recommend decreasing the resistor value and increasing capacitor to somthing like 4,700uf
But this is the capacitor which was available to me this time. I tested for 1 hr this circuit this works great.
Check the push buttons buddy even while making the video i have so long head push buttons which I was going to use in this but while testing the circuit. I got the same issue like you.
Thia is because small current was flowing through the push button even after not pressing the switch.
If you know about MOSFETs characteristics then you will find the mosfets gete remains charged after giving voltage to the gate. So, for discharging the gate we have to use a discharge resistor fron gate to gnd.
Now your circuit's led brightness is going low because your switch has some linkage. So it is grounding the gate current.
One major flow of the circuit is that you can not press the 2 buttons same time. Then the circuit will be short-circuited.
This is the main flow.
Hope this helps 🙂
@@Creativecreator Woops... my capacitor was water damaged that was letting ** Very Small ** current to flow and discharge it...
Replaceing the capacitor helped

It's a simple and good circuit.
Does the FET generate heat in the intermediate light?
Yes, it does. Because MOSFET is a simple resistive ballast in this circuit (like a variable resistor with electronic controls).
If you want efficient way to light LEDs, you have to use more complicated LED driver with current and brightness control via two PWM signals (the first is driving inductance from the positive side and conrtols voltage and current, the second is driving MOSFET from the negative side and controls brightness via duty cycle). Simple is not always good (actually, almost never).
@@Sentinel-1 Thank you
A simple circuit is the best
@@すんさと Simple circuits are great for learning electronics. But if you want something efficient - it can't be simple, because you have to handle many aspects of the circuit. If you really interested in this topic, I suggest you to learn Adrduino and the basic of the electronics - that would be enough to light an LED with high efficiency and convinience.

hey that will heat up the mosfet quite a lot when you turn on the bigger led on half of the full brightness.
30w in 12v so 2.5A max i think but the MOSFET is rated for 50A+ no issue at all. Full cool condition buddy. Otherwise I would showed to attach with the heatsink.
BTW if you want to connect 100W led then you will defenately need a heatsink.
😃
@@Creativecreator yeah
@@Creativecreator the MOSFET is rated for 50A+ when fully ON not when it operates in the liner region
@@viermidebutura @viermidebutura I am with you here, the circuit could be quite energy inefficient when the MOSFET is operating in the linear region and heat will be produced as a result. One must be careful when designing with MOSFET. However for a small LED application and the TO220 package with the metal back in this case probably is sufficient enough to dissipate the wasted heat. I wouldn't connect a 30W LED in dim for a long period of time without a heatsink.

PRetty neat video, leave off the music, and by the way, 3, 18650 batteries give you a rated 11.1VDC, not 12.6. Yeah fully charged they are around 4.2/12.6 but that drops off really quick.
I charged them before using lol 😁
Nominal voltage is 3.6V but if you're simply a dumb if you use discharged batteries
@@darkagelo1 Okay, so who are you claiming are using discharged batteries? Especially since Li-ion automatically shut off before they are "discharged"? And nominal is 3.7VDC ie that is their rated voltage, which would give you 11.1 volts, just as I posted.
@@Rem1061 i dont claim that in this video were used discharged batteries but if you use Li-ion at 3.7 volts yeah you use discharged batteries, an remember one thing this is a LED circuit not a vape build, if you put thos batteries at 4.2 in a vape you are drawing 60W, 100W or even up to 300W this circuit use 5w max with the tiny LEDs so the bateries dont drop that easily
@@darkagelo1 How can you claim a battery that is rated for 3.7vdc is "Discharged" when it is at 3.7VDC? that makes no sense at all. A 18650 battery is supposed to put out 3.7V when it is FULLY charged. They do go over, just like the 12v battery in your car gets up to around 12.5
All good, but the part I struggle with (or used to struggle with) is soldering the components together. Never used to get a solid connection ;-)

the last led the one composed of an array of micro leds usually work at 36volt or maybe there are models unknown to me at a lower voltage maybe 12v but it must have a much higher amperage. As long as the 3 LEDs light up in series, even double, ie 3 + 3 in parallel, it goes in accordance with the voltage of the batteries. the last led, on the other hand, which should have 36volts of voltage, I don't see how it can light up.
