i love this guy's stuff as well as his sense of humor. haha
All cool youtubers have cats! 🐱 Thank you for your creations, sources of good ideas
Thanks for posting Sorin, your video's give me great inspiration to make things and the info helps me do that !
Keep them coming please
Cheers from Australia
Thank you! I've been gathering details for building this exact project for the last few days and just stumbled upon your video!
I like before even watch the video.
6:30 to save some current/heat/power in a relay coil - you may run into problems using lower voltage because the contacts will arc more using a lower voltage- with less force the contacts move slower and arc more. Also, an old relay may fail to work as well at lower voltage.
The cure is to use the full relay coil voltage rail, but fit a few forward bias diodes bewteen the negative side of coil and ground. This reduces the voltage to the coil normally in steady-state conditions - but here is a trick - bridge the diodes with a large electrolytic capacitor (+ve side to lower side of relay coil, negative side to gnd) - the inrush current to the capacitor will create a pulse of higher current to activate the relay with more force. It will still arc when it disconnects but half the problem is solved. This was known as a "relay saver" in years gone by, though I've just searched for a diagram and all Google shows is ones with transistors instead. More diodes = lower voltage in steady state.
Remember to include a reverse-polarity protection diode across the coil for EMF protection.
Also works for fans - use lower voltage to run but higher pulse to start - often a 12V fan will run at 4 or 5 volts but needs 7 or so to start reliably to overcome friction. If you don't get much effect add more capacitance. Cheap large-value capacitors will do - no need for very low ESR ones. You can also tap into the diode string at different points to give different running voltages. I use up to 10x 1N4001 diodes for PC fans - this gives me 12 volts minus (10*0.6V) so this is 11.4, 10.8, 10.2, 9,6, 9.0, 8.4, 7.8, 7.2. 6.6, 6.0 volts depending on where I connect the fan. The capacitor must go from the fan bottom side to the gnd and the selected diodes, not across ALL diodes.
10 diodes is 10cents (assumes 1N4007) , so biggest cost is capactor.
love your videos Sorin, carry on the nice work!!!!
instead of all this hassle get a PD powerbank 20000mAh and PD trigger boards with 19v and 12v value then connect the dc output from the boards directly to the router
nice project bro thanks i will make one
Excellent project Sorin !!
Dude the original build was so useful. I made one for my modem& my router
i am waiting for 2nd part. This was awsome
Show. Depois volto pra terminar de assistir 👍
Well done, I like so much your channel, keep enjoying. Best regards from Colombia!
Great job there Sorin 👍👍👍
Great video and very entertaining!
that so many details that will DAGE YOUR BRAIN
Big Love from Bulgaria
IMO, it's better to make it 5S config and only use the 19V adapter from ASUS.
Not only it reduces complexity a lot, by not needing any charging module and relay, it also make you possible to double the capacity by placing 5S2P in there.
The downside is you can only charge the battery to around 70%, BUT that's also a benefit that it will boost the longevity of your cell, and also you can 2P your cell to counter this.
Nice project!
Salutare, fain proiect, aștept partea a2-a. Glumitele la locul lor :))) si explicatii cat cuprinde. Keep going. Spor.
Hardly waiting the 2nd part and the completion of this useful project. Thumbs up if you also!
Great presentation style and very useful and interesting content. Subbed here!
I watched all your vids because of the cats. I see that you have a paid promotion. That's good. Keep it up!
cant wait for the next episode
If you build it, they will come. Well it's true. It's my first comment. It worked 👍😉
After a loooooong time Dude! 🤪
Awesome work.
Foarte interesant si educativ, bravo!
Love you man..superb❤️
Using the diodes is a good idea, but you can go lower in voltage and still get reliable switching if you add a capacitor in parallel to your diode string. about 100uf at 25v etc. the cap charging current will bypass your diode string giving the coil a good pulse. this method also works for a resistor instead of a string of diodes. this is how I stopped door lock solenoids from heating up.
The best dad jokes of all the electronics-related channels... Yes, that's a compliment.
Nice video !!! I like your t-shirt !!! Greetings from Greece
Nice project
Awesome, thanks!
Awesome video👏👏🙌
There are only 2 Best electronics channel on youtube,
(1) Sorin
(2) Great Scott
Best Videos,
Sir. Sorin your project is very useful
I like your explanation nice.👍💥🤣
I like your t-shirt!!! "Creta for ever "
I like you sir..you are the best electricians
SORIN IS BACK, si la fel de comic ca de obicei :)
A new subscriber has comed !
Good job brother....
0:03 hahaha very interesting sorin
0:33 Sorin goes full Bezos.
Amazing
You could place the fan in a way that the blowing part should be towards inside and the air in part outside it will cool better
Love from Bangladesh
you should make a transformer with two outputs and add simple voltage regulators and few capacitors :)
If the UPS is fully charged and turned on by itself, then you should get a perpetual motion machine?
You are a legend :)
can anyone tell me why you need a ups with 12v and 9v?much thanks.btw,the project is really cool!
Hi another great video congratulations .I'm preparing everything to start build a similar project .I have just a question for you,what is the function of the battery switch?
hi. I wanted a switch to disconnect the battery, in case I want to check something about the battery, while the devices are running. or if I want to temporary power the devices only from the chargers and I don't want to unplug and reconnect all the cables, just turn off the battery switch.
@@Sorin_DIY Clear.Thank you
I have just one question how can I get another 12votl for my ONU from it? Basically I want 3 outputs, 2, 12V and 1, 19V
Hahah. I love you man. I really love your humour 😂
Hi sorin! Great project! Keep up the great work. One question, can i do this for 2 12v outputs?
yes.
no way i have the same idea and project box :D
Salut Sorin, cum putem lua legatura? Vreau sa iti dau ceva pt niste proiecte viitoare
Nice shirt theme. Phaistos Crete Greece...
Good
Ați putea face "surface speaker" ?
Bro.. Thanks but I wonder why no TH-camrs yet posted project of Bluetooth transmitter ( which accepts audio signal via stereo 3mm jack from non-Bluetooth tv, audio system) n transmit to a device like Bluetooth headphone or Bluetooth speaker etc. please can you make this small project video?
I have not found any Bluetooth transmitter video in youtube..
Most Router that work at more that 12v, internally have voltage regulator that can work betwen 10v and 24v, sure that router uses 19v can work with 12v
What if I replace the electrolytic capacitor with a super capacitor? will it work better?
yes. but it may take longer to turn on the UPS and charge the capacitors.
@@Sorin_DIY True but atleast it will give enough time for the relay to switch, thanks you so much tho.
Hi, just asking, if i onlye need 12V output, isi it OKAY to use 3s BMS with 6 battery? Not 8 like yours??
Hi. a 3S battery has a voltage range between 12.6V and 8.1V. if you want a stable 12V output, you will need a CC/CV buck/boost converter. it works, but it will have a lower efficiency, so a part of the battery energy will be wasted. because a buck/boost converter works with a lower efficiency that a simple buck converter.
👌👌👌🍻
Please make a led cube 4×4×4
Salut Sorin! daca ai resurse ma gandeam sa faci un generator electric încărcat cu panouri solare pentru o căsuța la munte sau o autorulota … cred ca ar fii de ajutor pentru mai mulți mai ales ca se apropie sezonul escapadelor! ms
Hi, i bought a 3s bms for my wifi router, which works fine , can i charge it with 12v charger of router or should i use any charging module.
hi. you need a charger with a voltage higher than 12.6V, otherwise the charging process will not be completed and the cells will loose capacity in time, because they are continuously charged and don't reach the overcharge cut-off voltage. you need to check what voltage the BMS need.
@@Sorin_DIY charge voltage?
@@Sorin_DIY how can i measure the voltage required by bms.?
you should find the charging voltage in the BMS specs.
@@Sorin_DIY i do has a modem and router which works on 12v (each). By connecting those in parallel ,both turns on but the modem restarts. How can fix that? I added a relay that turns off the battery supply when the power returns. But while charging the BMS with voltage booster the power from batteries was going to voltage booster .
You should VERY clearly mark the battery polarity on the socket and the battery. It is EXTREMELY exciting putting them in backwards in these kinds of holders because they dont have a spring. If there is a spring it will glow and deform and break circuit or limit current... the better solid ones like you are using will not.
hi. I did mark the position of the batteries, it will be included in the part 2 video.
Salut Sorin. Felicitari pentru ceea ce faci.
Te rog pune in descriere sursele exacte pentru componente... daca vrea cineva sa-ti recreeze priectul sa nu caute componentele prea mult.
salut. am sa adaug in curand si lista de componente.
So what if my brain was already damaged? Lol
Just love the puns! "Little Liers!"
At least you are not in a Corn Field... :-D
Wow great project! That a bummer now I have to wait a week to finish my build... :-(
Great Video Sorin! Thanks!
LLAP
P.S. Thats reminds me, I got my crappy cheap 12v dremel like that from Harbor Freight. Yep, it is crap but a good voltage draw to test stuff which is why I bought it... Lol
Foarte tare ai putea sa încerci sa faci propriul circuit variabil de tensiune
I would like to build a UPS like this but that is charged with a solar panel, can you help me with this?
It will have a few more components, I can help you with a few ideas.
ı wouldn't do that in this way.i would use the battery, BMS and inverter,we have certificated adapters of it and the inverter will give pure sin wave. 100W pure sin inverters have 96% up eff. So it would be much reliable ,cheaper and efficient way of this . Great work anyway have a nice day
Pretty simple setup . Gg
Diy some yt stuff like microphone , preamp , headphones amp . Etc , solar panel project . 5.1 audio system
Can I please have the full schematics?
The link in the description isn't working :(
I checked the link and it's working: i.imgur.com/aRKuvr5.png
@@Sorin_DIY Yea I had to use VPN! Thanks!
Very nice and informative video.......... ;* Could u please help me to build a mini USP with out put 19.5v/ 3.5A to use with my uncharging (damaged power IC) sony Vaio laptop. Thank you in advanced !!
hi. I want to make a laptop powerbank soon, I think it will be useful to you.
@@Sorin_DIY yes of course. I think it need to be portable as same as normal charger of the laptop. Looking forward to your video. Thx 🧡👍🏽
What is middle blue preset in cc cv module ?
I think you can use it to adjust the full charge indicator LED (middle), so it will light up when the battery is charged to the desired voltage. but I'm not 100% sure, I've never used it.
@@Sorin_DIY thanks you 🤜❤️❤️
What rotary tool do you have?

Wow..more an excellent project.
Can you publish the scheme?
hi. the schematic it's not finished yet. I will publish it with the part 2 video.
Thanks a lot but I like the red color, lol.
De unde cumperi componentele folosite in acest project?
Sunt firme in romania care au componente electronice?
salut. majoritatea componentelor le cumpar de pe aliexpress.com. mai cumpar si de la magazine locale Adelaida, Quintrix si optimusdigital.ro.
@@Sorin_DIY Salut! Pentru acumulatoare îți recomand nkon.nl,nu-s ieftine ca pe Ali, dar sunt originale și cu capacitate reală, nu fake-uri chinezești.
Apropo, te urmăresc cu mare interes, proiectele sunt interesante și prezentarea lor este un adevărat "entertainment" :)
How about a component list with links? Thank you
I will add the components list soon.
Yuhuuuuu
Sorin, would have not been easier to stack the batteries on top one another in a 4 cell top 4 cell bottom configuration and use a plug with either a strap, a clip or screws to hold them in so they can be removed at any time?
It would give a bit more space and still have enough air flow for the batteries.
Love the channel friend, can't wait for next video.
While that is true and correct. Sorin stated his friend wanted to be able to change the batteries easily. Doing what you suggested would make it a bit hard. IMOP :-)
LLAP
@@BrucesWorldofStuff It's a good point you make, but as an example:
USE an XT60/XT90 connector,
Use a 4x cell connector back to back (insluating between the holdersand wiring for required voltage)
Cut/make a door (either clippable or screw in) and glue to the side of the call holder.
This means means the cells can be removed and replaced easily, not really complicating the initial design.
@@liamburge463 Oh, Ok... I see what you mean. I was just going off what he said in the video. I had a Ham Radio mic that you had to take apart to change the battery. It sucked. I made a square cutout in the bottom as a lid I used the cutout and velcroed the battery and cut out plate in and now it it easy... Lol
Velcro and super glue works wonders... :-D
Thanks for the reply and take care!
LLAP
hi. I wanted to make it simple for anyone to remove the cells. and I just wanted to use battery holders with clamps, not screws or other components. if the UPS was mine, I would have arranged the cells differently.
@@Sorin_DIY I like the battery holders myself. No welding or soldering on the battery's. Just wire up the holder and plug in the batteries... As for the polarity issue I paint the 'positive' end white with paint and then paint a red '+' on it... :-D
Great video BTW!
LLAP
what is the backup time for 12V output only and i sent mail to you please check it
hi. I tested it with both outputs and it has a working time of about 3.5 hours. the router uses a lot of power. but with better lithium cells it will last longer.
hey bro can I charge ups over night
plz rply
yes
RESPECT.
In ROMANIA unde poti printa PCB?
Salut. nu cred ca gasesti in romania. iti recomand tot jlcpcb sau pcbway, ajunge destul de repede pachetul.
Multumesc si RESPECT🙋♂️
Amazing.... where is part 2
soon...
I think the fan was drawing more current because you had it in freespace (i.e., no resistance from forcing the air through the enclosure). Just a guess on my part.
Am intrat doar sa las un comentariu, vizualizez ambele parti odata 👍
Can you please make a laptop power bank
yes, I plan to make one, but it will take some time, I'm already working on other projects.
😍👌
every one is first but when they refresh the page they not first
😆
8:47 SUPPER FAN lol, that must've been foreshadowing for the fake specs of the fan.
Nice intro 😂😂😂😂 i would really appreciate if you teach some basics required info as well I’m zero experienced 😅😅😅😅
The reason why your cells has lower capacity than what they promised is maybe there were sitting more than a year. Did you tried to charge discharge it 5 6 times
hi. I think that's the reason. in the first test the cells had 1500mAh. after 4 cycles ~1650mAh. I don't think they have more to give.
Gauri de racire , cate doua chiar in dreptul acumulatorilor , pe lungimea lor .
