Wanna hear a REAL security siren built from scratch?
In today’s video, I’m building a powerful alarm circuit that hits louder than most cheap car alarms — all using just TIP42, BC547, a few capacitors, and a tiny speaker.

This isn’t just a DIY circuit…
It’s the kind of thing you can actually use on a car, motorbike, garage door, or even your own custom anti-theft project.
Small project — big sound.


🔥 What’s inside?

• Loud sweeping alarm tone
• Powerful TIP42 output stage
• Simple 2-transistor siren oscillator
• Clean wiring + easy parts

🔧 Parts:

TIP42
BC547
220µF
22nF
22k, 47k, 1k resistors
Button
8Ω speaker 5w
3.7V supply


If you like loud builds, real-world electronics, and circuits that actually *do something*, you’re gonna love this.
