advice

So I am currently in my second year of college in a physics major. I took my electromagnetism course in my second semester and I got a liking to it. However, the course was completely on a theoretical physics level and in the circuits chapter I didn't perform the best. Sadly I also flunked the...

Hi ! I'd like to build a 150W stabilized variable power supply (0-30V 5A) like the ones you can find on the market. But surprisingly I haven't really found a ready-made schematic, as if there was no consensus. I've understood that there are 2 types of power supply, linear with a large...

Good evening everyone, I wanted to buy a digital oscilloscope (50-100MHz/ 1Gs) in the low budget range(~200 USD) from the US but I don't know where to get them. I am not a US citizen so my relative will get it for me and he doesn't have a background in electronics so he can't test it. I don't...

With the start of the new academic year just around the corner, I was wondering if the EEs on this forum would provide their top nuggets of wisdom to help the next generation of engineers make the most use of their time in school. So what is your advice? What do you wish someone had told you...

Hey everyone, I recently enrolled in a computer science major, and one of the subjects has to do with circuits, memory, the cpu, logic gates etc. The problem is, I have absolutely 0 experience on such things, and now with covid and learning from home I haven't really grasped much of my...

With a hobby build I have an issue and was wondering if anyone has any ideas? Basically I have a 12v plasma tube light with two female spade connectors, the circuit board I am attaching it to has a two pin JST slot. The circuit board has timed light and sound functions. So was curious if...

Good morning all Iv had a bit of an idea and just wondering if there is anything out there or something similar as I'm not any good with coding. Iv build my son a basic gaming pc and he would like rgb but the mother board doesn't have a argb header, and I was wondering if a controller could...

I recently made a 8 bit adder and I'm wanting to convert the 8 bit out put to bcd, what is the easiest way I could do this?

Hello! I am coming out of college and am about to purchase my first oscilloscope! I am currently torn between the features of the Rigol MSO5074, and the Keysight DSOX1204G. I was initially leaning towards the Rigol, however after doing some research, I've found a lot of people having issues...

Hi, I'm a high school student who is doing a physics research project on the Mpemba Effect and various circumstances that may permit it to occur. My current concern is with the apparatus that I will have to use in the experimental part of the project. In view of that, I would like you to give...
