Risposta a @axealarm 🎶🔴 Music doesn't just play... it dances. This laser moves only thanks to the vibration of sound. Watch carefully 👀. #VisualMusic #SoundWaves #LaserArt

🎶🔴 Can you see music? I took an empty bucket, stretched a plastic film tightly like a membrane, glued a small mirror in the center, and aimed a laser at it. When the music starts, the vibrations move the mirror and the laser turns into living shapes projected on the wall, changing with every sound. No computer. No digital effects. Just vibrations, light, and pure physics. #Laser #VisualMusic #SoundWaves #Physics #Experiment

This is a simple audio-responsive circuit. In the video, I show the circuit in action with a single color to keep it simple and easy to understand. To achieve the full RGB effect you see at the end (on the ceiling), each color (R, G, B) requires its own transistor. This is just the first prototype. In the next version, I will improve it using professional 6-layer PCBs from JLCPCB for higher performance and more complex designs. I've used their PCBs in many projects, and they've always proven to be reliable and fast. 👉 Link in bio

Empty spray can? ❌ Don’t throw it away. In this video I show you a simple trick to reuse it and spray almost any type of paint 🎨 ⚠️ Important: always follow the manufacturer’s dilution ratios, and use only paints suitable for spraying. #DIY #SprayPaint #LifeHack #Reuse #Maker

I built a mini welder using just two AA batteries. 😳 No power supply, no complex electronics: just a simple setup and an amazing result. In this video, you can see thin sheets of metal welded together with virtually no tools. ⚠️ This video is for educational and experimental purposes only. #SpotWelder #DIY #Experiment #Electronics

💧⚡ A lamp that turns on using only water and salt. No plug, no visible batteries, no tricks. Just a simple experiment showing how surprising electricity can be. ⚠️ Demonstration / educational experiment 💬 Did you know this?

If this was a trick… it wouldn’t behave like this. Explain it 🤔 #Experiments #Physics #DIY #ScienceTricks #Curious

Is it real… or just an illusion? 🤔🔥 Watch closely before you answer. #Experiments #Science #DIYElectronics #MindBlown #MakerLife

This battery wouldn’t charge anymore 🔋 I fully disassembled it, replaced the damaged cells with new ones, and tested everything step by step with a multimeter. After rebuilding and balancing the cells, the battery is now working again. Upgraded from 4 Ah to 6.8 Ah – fully refurbished. #BatteryRepair #DIYElectronics #ToolBattery #Rebuild #TechDIY

In this video I show you how I built a custom DIY power bank from scratch. It delivers 17,500 mAh of real capacity, not just advertised numbers like many power banks on the market 😉 A practical hands-on project for anyone who loves electronics and wants to know what really makes a reliable power bank. #DIYPowerBank #Electronics #DIYTech #Maker #TechProjects
