Thank you for posting informative videos for the DIYer People can learn and expand their knowledge.
Fantastic work, dude! Really nice! 😃
Happy holidays!!!
Interesting video series and presentation.
Nice voice and I also like the video. Thanks!
You can also use some power supplies as electronic loads. I have some older HP power supplies and they can be used as electronic loads, up to 20-25% of rated power I think.
You cant use it as load for audio amplifier bcs of short circuit protection it is considered as 0 ohm during starting or when passing at 0 volt output
You crack me up. Cool video.
Interesting video thanks for sharing.
Nice video, thanks for the clear circuit description. I will probably buy a cheap Chinese digital electronic load only because they are, well, cheap. Just sourcing a heatsink of that size would cost me more than the pre-made circuits from China. However, if you're like the person in this video who apparently has access to piles of broken and discarded devices that can be scrounged for parts, then this circuit is for you.
I think I will try this. I managed to get a lot of heatsinks from burnt inverter AC boards. As for myself I will re cycle a couple of old cpu heatsinks from old computers. They happen to be compact and with high dissipation and surface area.
i love your voice !
Very useful 👍👍👍👍
Thank you!
No mention about max. voltage and current LED. I think it would be useful to know
Hello Kasyan TV. Can I replace the mosfets with power NPN BJT transistors such as TIP3055? Anyway I've been following your channel for quite long time ago and have learned a lot from it. Keep up the good work!
you should not, especially for higher power applications, and for this application, where we want a voltage to control our load output, as BJTs require base current to control.
Useful video
Love this vid kasyan i always watch your vid and make it can you make a tutorial withcalculation and design a astable milti vibrator for boost convertr please beging you..
nice information
Great job Kasyan. My question is how to connect the ampermeter that you showed here.
same way you connect an ammeter to anything, put it in series with your load...... If you aren't sure how to measure current or voltage, please don't try to build anything like this without doing this research first.......
ฉันได้ติดตามช่องของคุณ รัสเซีย มีประโยชน์มาก!!ขอบคุณ เซอร์!
What is the purpose of R6, can't the shunt voltage be directly connected to vin- of op1?
Can you plz make video on resonant wireless charging
hello kasyan what kind of flux did you use before tinning the whole board
U r Genius !
Can you do more videos like this
Cool, you should build a real Tesla coil, either based on class E or PLL.
sorry to be offtopic but does anyone know a way to log back into an instagram account..?
I was stupid forgot my password. I would love any assistance you can offer me.
@Malakai Jad instablaster =)
@Miguel Bo Thanks for your reply. I found the site through google and im waiting for the hacking stuff atm.
Takes a while so I will get back to you later with my results.
@Miguel Bo It did the trick and I finally got access to my account again. I am so happy!
Thank you so much you really help me out :D
@Malakai Jad You are welcome =)
Impressive
Awesome
thanks
This is not doing like resistor. Not linear
How to increase the voltage
Can you supply a the pcb in gerber form? for some reason im unable to open the file provided so cannot make this. i have the parts on hand but without the pcb the project is kinda at a standstill.
BEST
👍
Hi,
What does this circuit do?
good!
Please,where I live there is unstable power supply, I want to make request for simple AC power stabiliser circuits from 110-270 to 220 volts thank you.
I'd say to go out and buy one mate, it is simply not worth doing as it will cost you a lot unless you can salvage a lot of parts and even then you are putting expensive electronics at the end, risking their death if something happens to your device.
i want to make 2500W load with 250V max and 20A max. will it be build
I mean AC stabiliser circuit
HI, IS THERE A SIMPLE WAY TO BUY EXACTLY THE SAME PCB'S AS YOU USE HERE (OR IN YR OTHER DESIGNS.) I CAN BUY 10 AT THE TIME AND GIVE SOME AWAY I DO NOT NEED MYSELF TX
im 4x FGA25N120 Watt?
Pls upload the circuit &pcb details again, that link is corrupted
Dont use feedback to opam but i 'm not shure that mosfet conduct the same courant
That was my first and last order from them. Verry disapointed! I ordered a plumbing elbows that came in totally different shape and meterial, also the thread is not deep enough and can't be used. Anyway evebody can decide for themselves, but aliexpress lost me as a customer.
the archives are not any more?
Can you give the gerber files please?
11:05 I see that is how you increase it, thank you
I m Fga25N120 ????
Where is the Stealing?
hi can you please share gerber file?
If you're so concerned about potential thermal issues, why isn't there any thermal grease on your transistors to improve heat transfer ? Also, why is there only 3 transistors/fets on your board while you're showing 4 on the schematic ? Did you overheat one or simply decided to shot the video even if the board wasn't fully populated ? It would have been nice to have a link to the schematics and some decent documentation instead of countless links to buy all sort of material. If JLCPCB is having such great deals on PCB's, why aren't you showing one made by them instead of one you thinned ? Oh well !
just ln2 the tranzistors
Schematic?! 2:37 ....YW
Grab video
Please tell me how can we make a non stop vibration with magnets. Many fake video are on youtube. I believe you will show the proper way.
Stealing from China 😁😁 what a laugh
You're channel is supported by JLPCB which offers EasyEDA software to design boards and schematics, yet you provide files for another software that is not supported by EasyEDA.... this makes me sad... I guess I'll design my own board in EasyEDA.
sprint layout application
Well.....crude design at best.... those 4 channels should be better 'matched' to share currents equally....you're using 5% resistors... and those 'sense' resistors are crude wire wound type...might be 5 to 20% tolerance.... should be .1% 'low inductance' type.... probably a better approach instead of 'tinning' entire board with thick solder, would be to 'direct wire' the 'source / drain' with heavy gauge wire.... and the 'professional' load units give some sort of digital control of the load, that's why they are expensive, and much more accurate.... nice try though, might work if you're a hobbiest.....
Think the general idea was for hobby electronist . But the basics is there... A small controller and a DAC is needed ... I would prefer to use Bipolar transistors since is Linear and all ... Just a couple of medium power transistors are needed on the out of the Op amp
