EE for Everyone is dedicated to documenting projects that we build to solve problems, highlighting nuggets of good engineering practice such as defining requirements for a project and using prototypes to verify performance of critical circuits before creating a large project that uses those circuits.
We also take some time to discuss the components, principles, and analysis methods used throughout electronics design. Occasionally, we will even dive into how something like a switch mode power supply controller works! If I'm doing my job right, hopefully you'll take a nugget of information from each episode

I know this is super old, but why not use the microcontroller to detect when the load is 0v, and set the setpoint of the PID system to 0, so it will never fully enhance the linear fet when no source is connected. Id still keep the OCP, but it means you wouldnt be relying on it as much
More important is the tip being grounded? Many switching psu 's are floating and totally safe if isolated from the case .Did you check? Grounding a device intended to be floating is in it self dangerous.
I'm trying to build a SMPS using a 555timer as the high frequency switching IC,but I can't figure out how to power the 555timer from the 220v mains considering the circumstances governing the 555timer's voltage input range... Please need help
As a lighting guy, the one to many setup is probably one of the biggest advantages of DMX. It is so nifty to beable to set an infinite*** number of lights to the same address and run them all as one big pixel
In reality, that china pos egs002 is burning mosfets and igbts all over the world in them solar inverters they sell ; i repair them, and it is a shame that there is not one inverter that you can trust, especially on the transients,the "en route" on and offs.
Thanks for the great video! I have a LED panel that is controlled by RS485 but I want to convert it to DMX signal. Is there a way to do that? thank you!
Thank you for taking the time to do these videos, it was great to learn! Don't be afraid to slow down or pause when stuff is more dense/complicated, as non-native speaker I had to repeat some parts many times to get what you where saying.
8:15-9:40 this explanation was quite rambly and hard for me to follow the point of it (as a battery electrical engineer). Also I'm very confused how the conclusion of this got to a battery output of voltage of 15.5V for the LV input to the DC/DC converter? If the battery is resting at 12-13V, then how does the voltage increase under load? But other than that, very cool video and well explained overall :)
Interesting. So my friend's project of wearable UV large bill counterfeit check lights might have a hiccup because there's either not enough of the right level of voltage for the LED light... or because the LED is both too small and there's no focusing diffuser/lens.
I do not think it is advertised anywhere as a reflow oven. So I'm not supprised you are not able to solder without adding extra heat. But I think it might buy one because it seems to work very well as a preheater. It also looks quite descent for a Chinese made device.
Nice video. I am sure you know this already, but just in case. If a meter is unable to read a low value. Use the meter to read a known value that it can read. Then connect the two capacitors in parallel and test. Then calculate the difference to get the value of the low valued capacitor.
Man I just discovered your channel and I am absolutely loving it. Can’t wait to continue diving in, but I really appreciate the time you’ve taken to share your passion and knowledge of EE with us all. Thanks a ton dude, you’re a very effective communicator.
According to the datasheet "typical aplication" of both components, shouldn't you use 1uH coil and 732k-100k resistors in voltage divider? You'd want the voltage divider to dissipation less power? Also they mention to use 2x 22uF instead 3x10uF capacitor?
