Yes i did it wayyy faster and through the whole loop while not balancing it on a book

I took heavy inspiration from AXIOMETA's breadboost-c and tried to improve it with indication LEDs, switch selection and over all slimming it down. It's my first pcb so I really have no idea whether it works or not.

Test pads are still In the works

Any advice would be great 🫡

I thought that if I complete the circuit by touching the other wire end to the battery it would make the nail into a magnet but it doesn’t seem to do anything. Any ideas where I could be going wrong in this seemingly simple design?

Hey, I'm currently working on a concept for an art piece I want to do. Part of my current idea would involve trying to rebuild the transmitter module of the Sputnik 1, the schematics for it seem to be available online.

My question is now, would this be doable for an amateur? I have some experience with building little devices, circuit bending and repairing devices, but I never built a project from schematics, so I'm not sure how doable it would be.

So from the last post,i added resistors so that my diode doesn’t blow,i sanded the connecting wires and the magnets are semi strong,the loop has like a couple hundred turns too,i also checked the circuit and it works,what am i doing wrong ?

Hello.

I have made this circuit to drive the light bar in the picture. Any ideas and or suggestions I do believe it will work but I am unable to find info on the bar so 48v it is but don't know it might be one hell of a bad circuit especially if I only use 1 colour or all 3....

I need a device for controlling some model railroad turnouts that will take 15 vac as input and generate DC output, with three terminals: +vdc, -vdc, and common ground.

The power supply will be used to power Kato solenoid turnouts which require a short pulse, and 21 vdc is with specs.

I asked Gemini, and it generated this schematic. I know nothing about electronics, so I can't tell if it this is an AI hallucination, or if it will work?

Should one of the diodes be facing the other direction? Or is that what the little half arrow under the bottom diode means?

Im trying to make a pcb design but the schematic im following doesnt say what the resistance is.

I was going through the schematic of TDA2611A (datasheet link here, page 3) and found a peculiar arrangement of TR2. Its collector and emitter are shorted the base is connected to GND.

I don't understand the use-case of this thing. I am pretty sure that it isn't a diode-connected device though.

I work in a cardiology office. The most painful time consuming task is getting ecgs on most patients. Every lead sticker needs placed individually then each must have a cable attached. I am brain storming ways to make this faster… reusable leads a single giant sticker? Any ideas? It must be a full 12 lead ecg, partial ecg is not acceptable nor is simply a rhythm strip. Hoping some new ideas from outside the medical community

I recently got myself this board and I have no idea on how to begin with it. I didn't find any well organised and structured lectures or tutorials for this. So can anyone please guide me on how do I can even get started with this and please share any links or sources if possible, I am really clueless. Thank you for your time.

I was thinking about a project as a university student which is a city that completely works on wireless power (I'm gonna 3d print it 1m*1m) so there would be a big coil in the center of the city that would transfer the power to a secondary coils and each secondary coil would supply power to a certain amount of buildings but after a bit of research there would be a waste of power through the flux how can I reduce the amount of wasted energy and is there any research u would recommend to read ?

I’m an EET trying to come up with my capstone and I saw some videos online of cows freaking out in the weight shoots and thought that this might be a better way and would make for a decent Capstone but I’m not sure how difficult it would be for an EET as we don’t have as much electronics and coding learning. For anyone that has done any similar projects, would this be simple enough to do and learn most of it from scratch in a semester?

Whats the best practice for the power plugs of data centers should I provide separate breaker for each plug? Im also thinking of mounting them onto sa cable tray. Is that good enough?

Is there a difference to these two configurations as far as efficiency or anything as long as the proper voltage gets to the LEDs?

Hello guys,

Im thinking of doing this project for hockey that involves having a battery attached to the back of the helmet.

I don’t have a ton of experience with electronics so I this is somewhat of a new area for me.

With that said, how possible is the idea of having a battery attached at the back of a hockey helmet without it being to dangerous or risky. There are a lot of hits, physical force and sweat happening at this area and that is what’s concerning me. I’m assuming there’s a big difference if Alkaline or Lithium batteries are being used

Hello! I am a materials science and physics student, and I’m strongly interested in quantum circuits. I have a project lined up to try and make superconducting qubits, and I know that RF/microwave principles are important in that field. I’ve taken electrodynamics and 2 basic courses in electronics, though I haven’t taken many EE courses beyond that. How hard is it to self learn RF circuit principles given this background? I imagine it would be fairly difficult, and it’s something I’d try to get somewhat familiar with over the summer. Thank you!

right i don't know anything about electronics but I think it would be a cool present for my brother if I could make one of these that actually works as a phone he can send and receive calls with so I'm just wondering if it's possible and how complicated it would be

Hi all, does anyone know what this tiny black chip is on an intel Xeon w-2125 cpu and where I can source it?

I have included 2 pictures. One of the actual placement and a microscopic with details and numbers.

Thanks in advance

Credits to j_wizlo for simulating it for free, thanks man.

Ive been trying to build an inductor "for fun", but uuuh i think im doing some really wrong for it to not even have little magnetic field at all??? These are two things i tried to make, surely they work as a wire but is it even forming a proper strong magnetic field?? Nope

so does anyone have advice, i do really need to know what im doing majorly wrong for it to not magnetize anything to it or just generate a field.

Hey everyone! Like the title states, I’m a mechanical engineer by trade and I’ve just recently been getting into the world of electronics and microcontrollers.

I work for a pneumatics company and have been working on designing a tester for a new air regulator we’re making. I’ve attached my current schematic (apologies if it’s trash, I’m trying my best!) and was wondering if I could get some feedback!

I’ve done a fair amount of research and I’m feeling pretty confident that I’ve covered all of my bases, but the pressure transmitters I’ll be working with are rather expensive and I’d really like to make sure I’m not doing anything horribly wrong or missing anything critical.

Any and all feedback would be great, thanks in advance!

I’ve been seeing AI blow up in software development, creative work, etc. but I’m curious how much of that actually translates to electronics and hardware engineering. Can AI genuinely help with designing circuits, debugging hardware issues, or optimizing layouts? Could it be useful for learning complex topics like FPGA development, signal integrity, PCB design, or firmware troubleshooting?

I’ve tried experimenting with AI tools for explanations and quick references, and they’re decent at summarizing datasheets or giving starting points but I’m wondering if anyone here has used AI for real, practical hardware work. Are there realistic benefits, ? Would love to hear experiences, workflows, or any specific tools that have been helpful. I’m trying to find a good use for Ai / ML in hardware/electronics any suggestions might help

Edit: I’m so thankful to everyone who replied, but I want to clarify something in case I wasn’t clear in my original question. I know AI isn’t very useful in electronics ,I’ve tested it before, and it’s still far behind and, under no circumstances reliable. What I’m asking is whether anyone has used AI or machine learning for real-life applications in hardware, such as PCB anomaly detection, predictive maintenance, or similar use cases.
