SMD VIBE is a DIY electronics channel where ideas turn into real, working devices.
Here you’ll find creative, useful, and sometimes unexpected electronic builds made from real components — not theory, not simulations, but hands-on engineering.
This channel is all about:
— practical DIY electronics
— cool and unusual builds
— simple circuits with smart solutions
— experiments, upgrades, and creative hacks
I focus on making electronics understandable, satisfying to watch, and actually useful.
No boring lectures — just clear explanations, clean soldering, and projects you can build yourself.
If you enjoy electronics, tinkering, and seeing how things really work — you’re in the right place.
🧠 An engineering approach and a lively style.
⚡ Build. Test. Improve.

🎃 I Gave a Halloween Pumpkin Real Eyes! 👀
🎥 Watch the full project here:
👉 https://youtu.be/fYw16855Wy8
This Halloween pumpkin is not just a decoration… it has a life of its own! 😈
I built two synchronized animated eyes using ESP32-C3 boards and GC9A01 round displays.
Both eyes move together, blink, and create the illusion that the pumpkin is actually alive! 👀
What do you think? Should I add more expressions or even make it follow people with its eyes? 😁
Happy Halloween! 🎃

⚡ Cheap vs. Expensive Charger — Is There Really a Difference?
Two chargers with the same output specifications — but look at the difference inside! 🔍
I opened them up to compare their internal components, transformers, capacitors, heatsinks, and overall build quality.
But does a higher price really mean better quality and reliability? 🤔
What do you think — is the more expensive charger worth the extra money, or can a cheap one do the same job?

📱 Giving an Old Laptop Webcam a Second Life!
I turned an old Camellia CN0314-0V03 laptop webcam into an external USB camera that works with a smartphone! 📷
With a little DIY wiring, a couple of diodes, and a USB connection, I can now use this tiny camera to inspect hard-to-reach places — just like an endoscope. 😎
Who knew an old laptop camera could get a second life? ♻️

🚨 I built an SOS button using ESP32-C3!
Press the button → ESP32 sends an SOS signal over Wi-Fi → Android phone receives it → the phone automatically calls the predefined SOS number using its SIM card. 📞
The full project is open source: ESP32 code + Android APK + wiring + setup instructions.

🔥 Our 2SC5200 transistor heater just got a major upgrade!
🎥 Watch the full video:
https://youtu.be/gyJ4OJ2Ib7g
The heater now runs on an ESP32-C3 and has a color display that shows the SET temperature, actual temperature, current, UBE and POWER, so you can see what’s happening in real time.
We also added two buttons for easy temperature adjustment from 150°C to 250°C.
And the best part — the whole system is now much more compact! 🔥

I Built a Nixie Clock Without a Nixie Tube! 🔥 IN-14 + ESP32
No high voltage. No real Nixie tube. Just an ESP32-C3 + ST7789 and some custom graphics.
I’ve published the full project on GitHub — including the code, digit graphics, wiring and setup instructions.

What if you could replace an old electronic tube with a display? ⚡
Recently, I made a digital emulation of the classic IN-14 Nixie tube using an ESP32 and a small display.
And it got me thinking — what if we could use the same idea to recreate an entire range of classic electronic devices?
For example, we could build:
🕐 Retro clocks with displays that emulate IN-14 or other vintage tubes;
📻 Internet radios with interfaces inspired by old tube equipment;
📟 Vintage measuring instruments with digitally simulated tube indicators;
🎛️ Control panels and displays designed to look like electronics from decades ago;
🔬 And even completely new DIY devices that combine a classic retro appearance with modern ESP32 technology.
The interesting part is that the ESP32 can handle all the logic, while a modern display can reproduce the visual appearance of the original tube — without the high voltage, complicated tube circuits, or the need to find rare components.
Of course, a display can't reproduce the actual physical properties of a vacuum tube or Nixie tube. But visually, the possibilities are really interesting.
I think this could become a whole new direction for some of my projects. ⚡
What would you like to see built this way — a retro clock, an internet radio, a measuring instrument, or something completely different?

🤔 What if a single transistor could become a smart heating platform?
This temperature-controlled heating platform is built around an Arduino Nano and the powerful 2SC5200 transistor.
The Arduino continuously monitors and controls the temperature, while the 2SC5200 serves as both the heating element and the temperature sensor.
Special thanks to YouTube creator XUBOR007 for designing the original circuit and writing the Arduino sketch that made this project possible. This build is based on his schematic and code.

Summer is in full swing! ☀️ Time for travel, relaxation, and recharging. I hope you're having a blast!
I decided now was the perfect time to take a break from serious planning and give you (and me) a breather. So, I built this scanner just for fun and some unusual experiments. I hope videos like these help you relax a little and bring a smile to your face between tasks. 🔋🤖
How are you spending your summer? Have you gotten out anywhere yet, or are you still busy?

🌡️ Did you know that a regular digital voltmeter can be turned into a thermometer?
Most people use a multimeter only to measure voltage, but with one small LM35 sensor, you can turn it into an accurate temperature meter.
📌 No microcontrollers.
📌 No programming.
📌 Just one sensor and a power supply.
The LM35 outputs 10 mV for every degree Celsius, so temperature is directly displayed as voltage. For example:
• 15°C = 150 mV
• 30°C = 300 mV
• 100°C = 1000 mV
