What happens when a kid starts soldering?
Within just a few days, parents see the difference. Kids spend less time in front of screens, solder and build on their own, and learn how electronics really work. No shortcuts. Just real learning, focus and pride in a device they built themselves.
Why Parents Choose Lutovo
This is where learning gets real
Every kid wants to know how the things around them work — they just need a chance to find out. Lutovo turns play into learning: your kid solders, puts the circuit together and watches the model they built with their own hands actually come to life.
More skills with every kit
Lutovo kits grow with your kid — from the first simple solder joint to more and more advanced projects. Every new kit means a new skill and more confidence with a soldering iron. Because real learning can't be bought ready-made — you have to build it yourself.
🔍 Find hidden treasure!
Build it, head outside and start searching. When it detects metal, the LEDs light up and the alarm sounds! 🪙

What does it actually do?
It detects metal hidden underground — coins, keys, jewelry. When it finds metal, the red LEDs flash and the buzzer sounds!
What Our Customers Say
Why do kids love it?
Most toys get boring after an hour. Metal Detector DIY turns every walk into a real mission. Your kid isn't tapping a screen — they're searching, discovering and celebrating every find! 🪙
Why does it work?
An evening spent on one project, not on two separate screens.
Sparks Creativity
Kids don't just tap for an instant result — they decide for themselves how something should look and work.
Quality Time Together
A project that brings parent and child closer — instead of two separate screens in the same room.
Teaches Focus and Patience
Step-by-step assembly teaches kids to finish what they start — without closing one app and opening the next.
🔍 How does it work?
Your kid moves the sensor just above the ground — when there's metal nearby, the LEDs light up and the alarm goes off. It's a short-range detector, so it works best near the surface rather than for finding things buried deep down.
30 Days to Return — No Questions Asked
If the product doesn't meet your expectations, you have 30 days to return it. And if the detector doesn't work after it's built — we'll send you a new one or refund your money. Having trouble during assembly? Write to us and we'll help you by email.

How does the detector work once it's built?
How does the detector work once it's built?
You move the board close to the ground — when it detects metal, the 4 red LEDs start flashing and the buzzer alarm sounds. The closer the metal, the faster the signal!
Is it hard to build?
Is it hard to build?
For someone who has soldered before — about an hour. A bit longer for beginners.
How long does it take to build?
How long does it take to build?
Someone with experience can build it in about an hour. You can also split the assembly into a few sessions — no need to do it all in one go.
Does the kit include a soldering iron?
Does the kit include a soldering iron?
No, a soldering iron isn't part of the kit. But you can add one to your order — we offer a professional soldering kit and a protective mat.
