Bro for pcb design use easyeda or attach gerber file or something i cant access altium bcs its expensive
to download my projects, you don't need to buy a license. just register on the website using the link in the video description/article. I upload the projects files in the Altium-365 cloud space
Bro do using easy eda... Its much expense😢

Finally got I2C decoding working in my new SDS1202X-E. Turned out trigger settings was wrong. Your trigger settings work like charm. Thanks!
The first try takes time, after that it's a piece of cake
Thank you! C with Pi Pico disenchanted ;-)
This is a great tutorial man. Thank you sooooooo much!!!!
Glad you liked it!
Thanks for the tutorial. I have some questions to ask: how does it work as LM358 in the stimulation part because we only create the block diagram and footprint?
simulation is something else, this is for schematic and PCB layout
Thanks
Thank you very much. I hope others also follow you
Hi my friend; all your products is the best Good luck
Thanks so much
Can i use this for my audio amplifier (STK4221 II)?
Yes, why not. this is a very low noise supply
@@MyVanitar thanks, sound quality more better since i use this power supply
@@hemamadni2117 glad to hear that
thank for sharing! I have a pulse transformer with parameter: ***N1 [4-5] 0.15 / 160T, N2 [6-10] /0.35/11T,N3 [1-2] 0.15 / 14T cross*** It has 2 secondary winding, how can I use it in this circuit?
how much is the inductance of the primary in your transformer?
how much is the inductance of the primary in your transformer?
@@MyVanitar Sir, inductance as: Lp = (4-5) 2.50mH / ± 5% and it is PC40 Core
@@thanhcong9278 compare this with my calculations. if the primary value is close enough, the secondary winding affects the output voltage and current. I suggest you wind it yourself if you want to learn
@@MyVanitar Yes. Thank you for your help!
What happens when you short the output?
These chips are all protected against short circuit
@@MyVanitar Not true. Look at the schematic. When output voltage is lower than input (short circuit condition) there is direct current path through inductor and diode. It should have at least a fuse on input power line to avoid major disaster.
it depends on your input supply. also when the input drops below 5V, the chip turns off. Maybe the EN pin can also help, but for my case and purpose of this circuit, disaster never gonna happen
Hello! I simulated the circuit you made (by using a square wave instead of the UC3843) to check the components choice. I noticed a big inrush current on startup, approximately 50A (you have very big caps) when the demand of current is high. How did you manage to reduce the inrush so it does not destroy the components? Secondly, can you upload the calculus you used for every components? On the TI datasheet components calculus are for a flyback SMPS, and whan i tried using general formulas (from Phil's labs) i had really bad results with a lot of ripples. I wouldlike to do the calculus by myself. Thank you!
usually, a boost converter is more noisy than a buck. check my latest video. although the current is low, it shows a square wave ripple. a 470uF input capacitor does not cause such an inrush
@@MyVanitar Well i guess that the inrush current depend on the ESR of the cap. What formula did you ude to calculate each components values like input and output cap, and inductance?
with usb type c why don't you also try to make pd trigger board with let say dip switch to select output voltage then will have a wide range of selectable output voltage.
if you want other output voltages, simply change the feedback resistors. also, be careful about the voltage rating of the output capacitors
@@MyVanitar yes I understood.
When I graduated from school some years before the dawn of the Internet, I thought that I could do anything. Give me an electrical engineering problem, and I could solve it. Hardware, software, everything. How naive I was. Back then I knew the fundamentals; nothing else. Every time I watch this man’s videos, I see a real expert. I hope that everyone watching appreciates the quality of these works.
Thank you Neil 🙂
another good project.
Thank you! Cheers!
sir good job.
Most welcome
To answer your question, I think the shield of the USB should not be connected to the ground
I am agree
I have a power bank which can be used with this circuit 😊
go ahead and build it

Where is the link to the Altium-365 cloud where you shared this project ?
for this project, the link is inside the article which I'll put the link to the article later on, however, from now on (whatever is published after this), the link to the Altium-365 project will be provided directly in the video description.
Схема неудачная. Для измерений неудобная, так как Канал 1 показывает всегда напряжение на генераторе, а должен показывать кривую напряжения на исследуемой детали.

you've made a mistake somewhere, I'm sure. check again (both video and the article).
@@MyVanitar ok thnx for the reply

Hello Mr my name is kassahun Tamiru from Ethiopia Africa as you explain digital energy meter measure Active energy reactive energy ,apparent energy , active ,reactive ,and Apparent power and also digital energy meter measure instant current , instant voltage ,power factor and display any tamper event on meter LCD like Battery status , reverse connection ,ground , terminal open and Etc , my county single phase system voltage standard is 220 V and we use digital energy meter but our meter canceled the previous stored cumulative energy when our voltage decrement to 170V and below what will be the Reason for meter canceled registered kwh
I don't know, but a voltage glitch (on/off) probably caused this, because they calculate until their power is connected. to avoid this, you have to store the latest data on an EEPROM or something, every 1-2 minutes for example
Thanks for sharing very interesting topic as the above board shows the energy meter design for 220 nominal voltage what will happen if the voltage level below 220 V or 100V
nothing. it calculates based on the input voltage and current, however, I'm thinking about the capacitor-based supply for the chip (not the chip itself), that might cause issues if the voltage drops too low
I have another design as well, V2. check my videos you will find it
@@MyVanitar yes most of our meter lost stored energy on voltage drop areas , due to what reason happen or which electronic component causes
This is not the problem of the meter, it can be easily solved to handle even as low as 85V-AC
Great video thanks for posting
Bingo
Best explanation I found to make this setup, congratulation!
Glad to hear that!
Nice video. Thanks bro...❤ Are u from Iran?
how can i get 12vout / 4 amps from this design?
12V-4A means 48W. The maximum power of this Flyback chip is 24W. if you have a project request contact me via Email
@@MyVanitar i'm a college student and i wanted it for my for my project this semester, just having a trouble adjusting output voltage and current and controlling them separately . sadly i can't afford a project but i would really appreciate any tip you can provide .
I have a 12V-7A version on my channel. check the details for your info. The output of these supplies is not that much adjustable except you use a buck converter at the output
@@MyVanitar thanks .
Nearly fell asleep.
the same as a technical class in the university?

Traces for voltage drop sensing on shunt resistors network is far from best practices. You included a noticeable part of copper traces as path for current. It will cause less stable real current when the device is heating. It's not an issue for a hobby project, but you learn here people to do things properly, right? So, that's why I'm pointing this here for you.
I did not get what you meant, what's the problem with this layout?! when the copper is enough, it won't heat noticeably. open a channel and show your professional projects and do things properly!
@@MyVanitar I was talking about PCB traces layout. Traces where you sense voltage drop on shunt resistors. I'll be happy to continue discussion after you have a look on some doc. Please search for AD's document optimize-high-current-sensing-accuracy.pdf and have a look. That's much more close look how to properly do tracing, while on your PCB it's far from proper approach. Do not get me wrong, I'm watching your channel not to make critics. I've just spot this and want to pay attention. Will be happy to continue discussion.
@@MyVanitar I have to repeat a lost comment. I was talking about PCB traces layout. Traces where you sense voltage drop on shunt resistors.

The "maximum" power dissipation on the shunt is around 1.25W. the shunt is rated at 6W. can be increased to 8W. Resistors on the source pin of the Mosfet are rated at 12W and can be increased to 16W. maximum power dissipation on those 4 resistors 6W but they won't affect the current reading. This can be even improved if the value is decreased but the user would miss low current adjustments. Load ground and input ground are also common. current sensing is the high side method. if you mean the traces from the shunt to the chip, they are short and identical
@@MyVanitar I'm sorry, but you are still wrong and/or do not understand what I mean. Did you found the pdf I mentioned? Read it please! Your math about shunts wattage does not eliminate the fact that traces for main current sensing shunt (R9 || R10) are placed in a way that violate well known, proper tracing. Those sensing traces literally should go under shunts and have to be connected to internal side of pads where they soldered. Not like you have right now on one side which we see, it's even on some distance from soldering pads!
Nice my friend
Thank you 👍

Raspberry foundation has released a standalone Windows installer which does all of this in one single click. I would recommend using that as it really eases the SDK setup process.
please do not comment without watching the video!
@@MyVanitarDon’t be a jerk. I watched the video and that’s why I gave advice based on my experience. All the manual work of installing everything individually has been replaced by one click installer. What was wrong with my comment?
man, the first step of this tutorial is about installing that package, but that package is out of date, that's why we should update some parts. Please watch the video completely and be polite, I don't owe anyone!

Hello and thanks for the video!Can I only switch the Mosfets for having a power supply of 120V?
you should change some capacitors and the MOSFETs because your input voltage is higher than the voltage of these components
@@MyVanitar Thanks for the reply.The capacitors I have to change are C5,C6,C7 am I right?
@@upbgenoob5488 honestly the PCB should be modified to follow the higher voltage standards, but what I told you was the minimum action, otherwise those components will explode
