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 ..
Dear sir ,
It is better to provide cirkitdiagram
Will help us to try taking screen picture to built cirkit easly.
Thank you dear.!
❤️
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.
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
Make a switching circuit...IT geht's hot...
Many happy homes! Question was, Does work for doggie? Many toys stumble but doggie works great! Happy Christmas you and all doggies!
That's the best way to look simple circuit so complicated... ;)
Thank u very much 💖
thank you for that sharing
U welcome ❤️
Nice👍
A heat sink would make this able to handle much more!
You can use heatsink
Good idea, usable
Thanks 👍
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.
DC 3-30v 1-5 ampere input voltage you can use
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!
how is it possible the potmeter doesn't burn up when turning it to less than 100 Ohm or so,it is directly connected to dc and to base.
such potmeter burns up very fast is my experience
It will not burnt while using TIP

Hello RJ
Can you make this....
mini digital metere displaying consumption in UNITS (Not KWH) as charged by electrical company.
this will be used in home main panel to give consumer idea about his consumption of electricity.
It Pakistan normally electric supply company speed up their energy charge meters by 30-40%

What's with it what's with these silent electronics porn videos? I can't see the appeal of makers videos that don't explain what's actually happening.
Clear details in the video
@@RJEDITALL Just saying it is hard to follow. You do put brief text boxes saying what some of the things are. Maybe at least leave them up long enough that it's possible to find them without rewatching every piece of a silent video? My point is it is very hard to make something from a video like this as compared to when people discuss the details of what is going on, and why they are doing things. A parts list in the description is also helpful.
На видео красиво, в реале так не работает если выставить на таком примитивном зарядном определенное напряжение то после зарядки будет напряжение выше на аккумуляторе чем изначальное. Ловкость рук.
