Hot Plate Reflow Board / Process
มุมมอง 1134 หลายเดือนก่อน
Using the MHP30 and as well looking at its capabilities for what we want to use to reflow our boards. The board is a sensor "playground" board where we have multiple sensors with pin outs making it easy to debug, write firmware and essentially play around with it. The MHP30 was kindly gifted from PCBWay but as well helped in the manufacturing of the PCBs, I am more than happy to say that the qu...

Making Modifications To A Design
มุมมอง 964 หลายเดือนก่อน
Reviving an old project that had to be finsihed and completed. A simple modification to make though could have been easily avoided. A lot of time, besides design we will need to have practical skills as most of our life we are faced looking down at our boards in either debugging, reworking or simply admiring. This time we solder a micro usb and make a simple wire change.

I've been a little intimidated about figuring out this part of my circuit, and your video helped a ton. Even just your tip about the free tools to design my antenna and impedance matching circuitry. Thanks soooo much!
'Promo SM' 😘
lets go i am ur 1000th sub
Thank you for your video!
Sir, i need current sensor which operate at 300v and 60A . And it should give alarm if its decrease than 10 A.
Very nice
Great tip about moving them as close to the driving pin as possible!
Eto na ange pinapanood ko na
Might be a good video, if anyone could hear it...
Awesome! Thank you very much!
Your sound volume is not possible
could you have a walkthrough for interfacing sht3x with STM32?
Yes I can do
I have one question, when you declare the buffer, how do you decide the size?
Well, each type has a set size, so for example if you know for example you will receive two bytes of data, then youd declare the buffer size of two bytes. If I am unsure perhaps ill decide something arbitary and see how that goes.
Please help me, if I have a circuit that has an output of 50-200 mA, what sensors can I use to monitor this current?
If you need accuracy, as well simplicity I would suggest to use a shunt method current sensor, something such as the INA219, very simple to set up and reliable.
Hi, Very informative tutorial. Could you please make a video on this chip, PN532, and how to design its antenna?
Hi I will definetely take a look at it!
Underrated channel. The mastermind appreciates your contribution.🧠
You look to know a lot so can you explain to me why am I getting 3.5 volt on the output of the op amp alway and if I add 1 millivolt to the no invertering I don’t get any gain from the ua471 and it data sheet said it’s gain is 1000 time and I don’t get any gain till I add 1 voltage the gain gos full the supply voltage why is this and I need it to sense current to control my load
Can you tell me how use Zmct103c sensor to know if there is a possibility of a short circuit
"promo sm"
You left out the most important category, cost!
Of course! I always say cost is the most important factor! Think it influences most of our designs!

Do you do freelance projects? Where can one engage you?
Yes I do indeed, please contact me at: wintercircuits@gmail.com
How can we adjust the code to decimal places are printed, not just .0000?
Try %.2f as a format specifier.
great video, just 1 question why in your example E=A*C, as I understand it should be E=B*C?
Great video. Thanx
can i attach an antenna tht i bought online to my 13.56 mhz reader? if so, which antennas would be compatible with which models of 13.56 mhz readers?
You'll be able to use an external antenna as long as its for 13.56mhz
@@WinterCircuits do you know approx how far the 13.56 mhz nfc reader would be able to reach with an antenna?
🙌
Hallo i find it very good .Can you Upload the Code please
Added it in the description.
@@WinterCircuits thank you for the code but it does not work with I use the stm32F411RE and I modified the code but still it does not work. I would like to have your idea on it
@@alkhadizadiallo6362 Do you get an error or is it not communicating? Could you elaborate on the problem please, lets solve this!
The comment on "print your PCB out on paper" is a great one. I take it a step further, and glue that printout to a bit of acrylic the same thickness as my intended PCB . I have one in front of me now :) Really useful, as you can drill holes and fit connectors to see if they *really* fit. The acrylic can be drilled and screwed into an enclosure, enabling demo proof-of-concept products. Which is what I'm doing now
Brilliant idea, never thought about that!
hey great content! This antenna can be use for wireless charging? thank you in advance!
I have seen some cases with the use case of NFC charging, for example I believe ST do a range of chips. I would believe if it was that specific you could use this for wireless charging if its NFC. In case of QI charging, it would require something different. You can get a lot of off the shelf antennas so it might be worth looking into if you need something for your project.
I watched your video it was very informative thank you! However I was wondering if you would be willing to help me on a project, I am building my own welder compressor generator and I'm trying to make an electronic auto throttle I have a good strong solenoid to shuttle the throttle back and forth with a return spring built-in so I only need 12 volts applied to a solenoid triggered by a current sensor my weld output range is between 75-200amps dc and for advice or design would I would be greatfull for, Thanks again for your time and your video!
Hi Alex, thanks for the feedback! I would be more than happy to help you along for your project. Let me know what's the best way to get in contact with you and we can discuss requirements and what we can do.
Help needed..(Question) I have a 12v motor that works off a key fob opening and closing a sunroof..it has 2 buttons..one opens it one way completely..one opens it the other way..but nothing stops the power going to the motor unless you press the button again..even when motor is maxed out..unit keeps powering it until it blows something..i need some sort of current switch that will break the circuit momentarily when it bottoms out as killing the unit will stop the process..if i forget to press the fob to stop the motor opening it will fry motor..so essentially what i think i need is like a self resetting amp adjustable fuse..but not thermal as it will take too long to reset also..hey man..nice video..thanks for all the info..i have a nice little project on at the moment, would love your advice
Thanks glad you enjoyed it! Depending on your design whether you want to go noninvasive or invasive you should be able to get modules for these that have a relay embedded in so you will be able to turn the relay on or off depending on how much current you are drawing through the sensor. This is one solution of many, let me know if you'd like to have a chat to discuss further. Hope this helps!
@@WinterCircuits aw cool man thanks..i will check what amps its drawing in regular use and see what it spikes to when stalled out .thanks for quick response
@@emmettcoen No problem, let me know how you do and if I can help you out in any way.
why not using switches at the ends of the movements
Does this increase the scannable range for NFC Chips?
If you mean will designing the appropriate antenna will you get further range for what NFC allows? Then yes.
Your tutorial is absolutely the best for me 😁
@@rabbitoose1381 Happy to have helped!
Have you ever considered working on projects with multiple people? I've always wanted to form a group of engineers and create stuff together, learn from each other, and make some really cool stuff. If your interested, I can show you some of the stuff I have worked on and maybe we can come up with an PCB to create.
That sounds really interesting, would be really interested in doing this type of thing. Let’s get something organised.
Not sure if my last comment went through but I sent you my email
@@Rtech98 No it hasn't, not on my end at least. I have listed my email on the "about" page of the channel, if you could send me an email there please and we can continue talking. Thanks
@@WinterCircuitschecked the description couldn’t find it
Good stuff man, although I find it a bit hard to understand what your saying sometimes, don’t be afraid to slow down a bit to get your thoughts out clearly. This stuff is complicated, and from experience I’ve learned that rushing, especially with electronics leads to faulty boards and design headaches. Also a lot of your silkscreen had vias on top, stitching vias are great and should be used if the top and bottom layer of your board are ground but they shouldn’t intersect with silkscreen, this will create holes in the text when produced. Definitely a step up from your other designs though good stuff
Thanks man, I’ll take that on board. Yes definitely! I’ve had some cases where, though the vias are tented like you said the silkscreen gets printed but still comes out funny or holes still appear in the text. Though like you said if can move silkscreen off it then always better. Thanks!
Dam bro your videos are getting better, keep it up 👍
Thanks bro, really appreciate it!
You mention Bluetooth...is this technology embedded in smart appliances? m.th-cam.com/video/5hK6GHYZtc8/w-d-xo.html
matching for maximum power transfer and matching for minimum reflection are not the same. had to figure that out the hard way. maximum power transfer requires the load impedance to be the komplex konjugate impedance of the source, minimal reflection requires them to be the same. so only one criterion can be met ( unless you work in dc)
Thanks for sharing that, its much appreciated and can see the confusion it causes, upon reading more I see the error in what I thought. Thanks for pointing it out!
@@WinterCircuits as long as you work in just real resistances, so no reactances, they actually are the same thing, manufacturers will tell you that their products are purely resistive but in reality, most of the time they are not ;)
Why don't you flow the gnd pins fully with copper, the ground return current should have the lowest possible impedance and with such a small via there are no soldering issues?
Hello, thanks for bringing this up. I am not quite sure which gnd pins you are referring to, and you are absolutely right that they should have the lowest possible impedance and providing a return path.
Thank you so mich for this video!
Very welcome!
Came across your channel pure gold
Thank you! Glad it’s useful!
Nice video very informative maybe you could add a test switch circuit to confirm the device is fully functional?
Thanks, glad to hear it! I’ll have to implement more functionality in the next iteration, thanks for the suggestion.
Board came out really nice! SMD soldering can be tricky at first, but a really useful skill to learn, and once you do you'll avoid THT components as much as possible trust me! Also, what do you do when you run out of project ideas? This is something I've struggled with I've seen Phil's lab say to make each project more difficult and stuff that you really need, although there are many times where I can't think of anything I would actually need or use.
I’ll be sure to crack on with it and learn, excited to try! Ah I get what you mean, it is hard to come up with a project that you will need. In that case, I would usually think of something that might be useful for someone else. I assume you are quite an experienced engineer, but what about fiddling around with other topics in electronics RF, analogue, power etc ?
@@WinterCircuits Thats a really good idea, I think one of my biggest struggles in terms of designing is writing firmware, I’ve only delved into C++ and Arduino, so I’m planning on learning STM32s as the next step up.
Definitely agree with you on that one, the amount of more things you’ll be able to do when you do learn it though!
Great stuff man, mic quality’s much better, some solid tips too I used to make a lot of the same mistakes as well. Never used altium before, the price tag put me off so I just stick to Ki CAD 6
Thank you, glad you are enjoying and the feedback has helped a lot! A steep price tag indeed it is, though its a nice package and am grateful to be have the opportunity and chance to use and learn the tool. I do have to say though, there is about a hundred different ways to do an option in Altium, and KiCAD keeps things nice and simple I find.
