I have one question, when you declare the buffer, how do you decide the size?
@WinterCircuits 8 ай бұрын
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?
@WinterCircuits 8 ай бұрын
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.

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

hey great content! This antenna can be use for wireless charging? thank you in advance!
@WinterCircuits Жыл бұрын
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.

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!

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
@WinterCircuits Жыл бұрын
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!

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
@WinterCircuits Жыл бұрын
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!

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)

@@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 ;)
