12V, 24V or 30VDC ....What input voltage were you using?
Maximum 24v
Why Usefull, and very usefull tell in advance the name of the product that is usefull
Many happy homes! Question was, Does work for doggie? Many toys stumble but doggie works great! Happy Christmas you and all doggies!
Hello Brother
Thanks for compact unit. Though I am a beginner I will definitely try this.
1) It would be worth if provided circuit diagram.
2) Will the circuit be automatically cut after full charging(4.1v or 4.2v)18650 ?
Hoping and waiting for such useful compact projects .
Thanks
Ok, u welcome
Wow. Simplicity at It's finest. Yet another project to build and use. ❤
❤️
WOW!! That’s soooo simple. Thank you. Two questions if I may.
Will this work as a dimmer for a few LED’s & is the display a simple 3 digit 7 segment display?
Thank you 🙏
You can try with led
Thank you 🙏
I think this display has a built-in voltmeter circuit, that's why it has three leads: power, ground and the voltage to measure
As far as I know, LED dimmers provide a constant voltage (12 / 24V) and variate the current (for ex 0-30 A) . As far as I can see, this circuit only controls the voltage output and has no impact on the current . So if you want to power a LED, you set it to 5V to limit the voltage (for a white LED - voltage differs for other LED colors), but unless your power supply provides max 20mA (ideally 10mA if you want your LED to last), it will exceed the max current supported by the LED and it will burn it. So you will need a current limiting element as well, in thia case, a simple resistor to protect the LED. I hope this helps
If the input is 12v, will the output be 0~12v?
Should the input be greater than 13v if the output is 12.6v?
All details in the video
Dear sir ,
It is better to provide cirkitdiagram
Will help us to try taking screen picture to built cirkit easly.

What for the device is being made?
For battery charge
Thats a BAD idea for charging batteries. A dedicated USB charger is FAR cheaper than the parts needed to make this.
Not if you can scavange from youre local trash and recycler places .its like a wonderful beautiful place with broken items with motors and switches and wires .one of my favorite places to go is the metal recyclers.such good sfuff ..just sn idea if ya havent thought aboit it it moght help knock down the price of things for ya .and invent we do . good luck mate .
It has multi voltage output
@@nafyadgetachew7322 But NO current limiting. As a DC lamp dimmer or motor controller, it's ideal. As a battery charger, it's terrible. Put that on an unprotected 18650 and see what happens...
@@mustangandfrankenstein If you think that's a better use of your time than spending 99p then fair play. I'm all for reusing old bits but my complaint is that this is NOT a good battery charger. Irrespective of the cost.
@@Cornz38 cost?there is no cost if gou do whst i do .and that is to see if i can mske it cheaper or by doing exactly what i said to do..recycle and depopulate nobody said that he was going out and buying brand new state of txxxxx art electronics or maybe i missed it ..free or close ...recycle yards .check one out ..
what input power?
127v or 220?
DC supply input with transformer
A mess of wires and solder spots, that won't last long...
Use of a prototyping board would be a better solution...
Another issue is use of a regulator without a dissipator: if the load draws too much current, it will heat up, and even if the output current limitation comes into play, this condition will undermine the circuit reliability. When a current limit condition develops, the regulator output will drop to a level that guarantees that its overall power dissipation is within limits., but since output voltage is lower than expected, it will be no use!
The large tab of the regulator must be connected to a dissipator to ensure a regular operation.
Another issue is the order of connection of supply and output terminals: the "cold" Terminal ( black) must be connected first and the "hot " Terminal ( red) afterwards!
Driving an inductive load like a DC motor, might result in the driver destruction , if no protection device is used, like a diode or a zener: check the application note for proper operation...
this man basically says: it has no protections, it will burn.
@@computerkiller1494 it won't burn in any conditions 'cause over current or thermal protections will prevent from destroying the regulator but the device won't work as expected.
It depends on the current value which is dictated by the load current!
I had prepared the same 20 years ago at my lab and it is still working. But I used normal NPN transistor 2N3055 in place of TIP

hey dear,
can you share me one thing how many volt given to supply voltage into circuit.
because you only made to circuit and you set dc voltage to charging battery.
so please share it how many supply power need.

Welcome ❤️
Yikes. How many amps did you dump into the poor 18650? Explanation of the components used would benefit the viewer greatly, and avoid much confusion.
Dear Jeff,
The amps a battery takes is dependant on the voltage. High amp chargers do so with high voltage. Therefore, setting the voltage at a low level such as 4 V for a lithium cell can only bring it up to its maximum voltage without high amps. Theoretically, you can keep a lithium battery at 4 volts permanently. The battery was already at a pretty high voltage so it wouldn't have taken much current. It would be better to have an ammeter just in case but I doubt the battery will be ruined at that low voltage because the small potential difference won't allow much current compared to a high voltage high amp bulk charge that later switches to constant voltage. 13.5 volts is a low amp charge for a lead acid battery, and you can keep it there forever too. A constant current charger does so by increasing the voltage and decreasing the voltage.
@@beyondwhatisknown well replied
@@beyondwhatisknown that's not how volts and amps interact. You can have drastic ranges like 100A at 0.1V. I believe OP used the wrong terms in their question, but your reply insinuated that if you have low voltage, then the amperage is guaranteed to be low, which is absolutely untrue and dangerously misleading.
you'll notice nothing melted and he didn't snatch his hand away from the transistor when he touched it so I am assuming the amps dumped weren't impressive.
@@SeanReevesD There is an equation which predicts amperage according to voltage and resistance. Everybody learns this equation in school. Only a short, broad, highly conductive piece of material will carry 100 amps at .1 volt difference. This low volt high amp circuit is used when you want to make something thick get hot, such as making a butter knife hot so it cuts webbing in your back pack factory, other plastic cutting requirements, or a classic soldering iron with a trigger. Tiny rechargable 2032 watch batteries will not pull huge amps at a small voltage difference, nor will a AA or AAA battery, nor will a small lithium ion battery, because small parts have a lot of resistance due to the fact that the electricity need to go through their small chemical electrolytes. A 12 volt car battery requires 16 volts to go into fast charge high amp mode, but once it's 80% full the intelligent charger will drop the voltage and slowly top it up. Then it will drop the voltage to .8 volts above the battery's 12.7 maximum voltage and let it sit there. My charger puts 2.1 volts into 1.2 volt rechargable batteries. I know because I've measured it. No massive amp dump. Battery internal resistance is different for each battery, but the chemical electrolytes do prevent the battery from acting like a thick high voltage copper cable that easily conducts power at low voltage differences. Use an amp meter to figure out the actual amps drawn by a particular 18650 at a particular percentage of charge, at a particular voltage difference,and then you'll know for sure.
What does it do and more info on the components you used would be nice
Thank u very much for visit 💖
If you don't get it, you don't get i guess. This is like "the easiest electronics ever"! Maybe You have to amplify your knowledge a little bit! A little bit is enough to understand this. That's what I love about this channel...!

thks you ...your video nice
U are most welcome ❤️
Okay, good job, but what is it used for? 🤔
Well with a transistor some led's and a relay you can make an auto shut off for charging any type of battery. Maybe he will make a video showing how that circuit is made, its very easy. But if you would like to know how to make that shut off circuit you can find it in loads of other channels here on RUclips. It's a very easy but handy circuit to know. You should check it out. Just look for charger shut off circuit using a relay and transistor. You WILL find it 👍

@@ACWindings if you use a transistor like a 2N3055 that can put out 15 Amps.

Hello, how much can the input voltage be?

What is the maximum volt output this circuit can give and you have not used a diode so it is running on A/c volt. Am I correct
I am using transformer convert dc , You use DC volt input maximum 30v 5 ampere dc voltage
There is no bridge rectifier and he was charging a battery. That would make it running on DC. Maximum voltage and current would depend on the transistor used.
@@RJEDITALL bro correct your wording... Say I'm using transformer 230/30 volts & 5 amps capacity at out put with Rectifer + filter section to attain DC voltage, cause you know transformer can't convert AC to DC/ DC to DC/ DC to AC, it only works for AC to AC transformation
