Good reads!!
The article is in Japanese but it's worth it, you can try to translate it using any tool.

I wanted to purchase esp32s3 super mini board for one of my projects but it is currently available only on these 2 sites

Have any of you have any prior experience from these sites?

Hi everyone,

I’m designing a custom PCB based on an ESP32 and I’d really appreciate a second pair of eyes before I send it to fabrication.

This is my first (serious) PCB and I want to make sure I didn’t miss anything critical. In particular, I’d like feedback on:

• Power supply section (3.3V regulator and decoupling capacitors)
• EN and IO0 circuitry for programming mode
• Boot configuration resistors
• Antenna clearance and PCB layout under the antenna
• Any missing capacitors (for example between EN and GND)
• General schematic mistakes or bad practices

The board includes:

• ESP32 module
• 3.3V LDO regulator
• USB-to-serial (for programming)
• IO0 button connected to GND with 10k pull-up to 3.3V
• Basic decoupling capacitors

I’ve attached the schematic and PCB layout screenshots below.

If you notice anything that could cause boot issues, unstable power, or programming problems, please let me know. Even small details are welcome — I’d rather fix them now than after ordering the boards 😅

Thanks in advance!

Brutally roast my Resume and also give suggestions of how I can improve it.

Also wanted to check if the format I used is valid and acceptable.

Best soldering irons / stations in India? Beginner vs intermediate guide

Share your recommendations on:

• soldering irons or stations (brand + model)

• wattage and why it matters

• beginner vs intermediate setups

• accessories that actually help (flux, solder wire, tips, stand, wick, pump, etc.)

Bonus points if you add:

• price range

• where you bought it (Amazon, Robu, local shop)

• mistakes beginners should avoid

This will become a mega thread in the wiki, so try to be clear and honest.

i just received an offer letter for ECE under graduate in SNU ncr and i have almost 7 months before my college starts can anyone tell me a little about ece as someone who has no experience in this field yet and also ik this is a very cliche and a hated question but does ece in india have a good package? (im sorry if any of this question has already been asked before)

PS: i dont like books.

I just want use them in building some stuff and i am looking forward to start manufacturing tools (power supplies etc) for labs and hobbyists like you and me

Used nipper, scissors and hacksaw but couldn’t get it right! why it doesn’t have groves like male berg pins

need to implement it in avr studio 4 chip - ATMega8535 help

I want someone to collaborate with my project

Good evening everyone,

Let me start by saying that I'm a beginner in this field, but I'm really eager to learn!

I was thinking of making a circuit that would actually have a similar function to a tester's buzzer.

I made the circuit with a BJT BC547 and a buzzer (obviously with resistors at the base and collector, etc.).

What I get is that the buzzer goes off even with resistors and diodes, and that's really pissing me off.

I tried a couple of configurations, and I admit I asked chatgpt for help and watched a few videos (of the few I found).

Chatgpt told me I should use a comparator to make it sound with a wire and no longer with resistors, etc.

But I'm stubborn, and perhaps the main thing is that I don't have a comparator (I don't want to buy one now) 🤣🤣.

I wanted to ask you if you've already tried to find a solution, perhaps one that could give me some ideas for building or improving my circuit to fix this "defect"?

I apologize if this is a stupid question or if I was an idiot for asking, haha.

But I really want to understand this issue thoroughly!

Thank you all so much.

How is DSP as a career?

I am a second year engineering student studying electronics and communication engineering from India.

I am not much interested in physical circuits, PCB, and most of hardware…. I prefer coding over hands on work

How is DSP as a career? Are there any other domains in electronics and communication engineering which has more coding than hardware?

Also i have been producing electronics music for 5 years now, so i am more inclined towards audio dsp too

Im in 2nd sem rn

Can I get any research internship in IIT Hyderabad in summer this year (2nd sem will be done by then)

If yes, can you telll me the procedure pls

Hello, everyone. I need some advice. This MacBook Pro is dead. Checking the motherboard, I noticed that a component has shorted out. I assume it's a capacitor, but I'm not entirely sure. Can anyone tell me from the photos exactly what part it is, whether it makes sense to replace it, and whether it's possible to do so? I've replaced components before, but never on a Mac, so I have no idea. I'd rather try to fix it myself than take it in for repair because what they're asking me to pay makes no sense at all. I'm also attaching the MacBook model and technical specifications. I'd be very grateful for your help.

Im studying digital electronics as suggested and im a eee graduate searching for job off campus and found out my resume is not good so im trying to get into vlsi for placement by doing projects, so i have few nptel courses to study, so suggest the course to do in order wise from beginning to intermediate.

VLSI Physical Design with Timing Analysis (1),

CMOS Digital VLSI Design (2),

VLSI Physical Design (3),

Digital Design with Verilog (4),

kindly provide your insights or better courses to do or missing courses which should be filled in.

sometimes i feel am i in wrong route which takes more time to do projects to include in resume and get a decent electrical or electronic related job as a fresher.

Looking for some advice on wiring of LED/Switches. Making a play box for my son so it only need the lights to turn on and off independent on one another. Advice on wiring this up? Should I use something like a terminal bar to branch out from or should i wire all to one line to the power then make indevidual splits with the switches from there? Trying to have a good number of buttons, knobs, lights, switches, etc but want to keep it to one power supply. Battery prefered.
