muito legal bem feito e divertido. veio ate rapido. so acho que tinha que vir em uma embalagem mais resistente ou dura para nao deforma o anel de induçao
Awesome
Arrived in good condition.All 10 LED's work perfect.You get 2 LED's of each color,Blue ,green,red,white and yellow.I would recommend this products.
Ottimo prodotto funzionante entro gli otto centimetri indicati. Sono presenti 10 led (2 per ogni colore giallo rosso bianco verde e blu). Funziona anche attraverso il legno alto 2 centimetri.
Very nice and funny module with lots of possibilities using your imagination. 10 LEDs attached to a small inductor are provided in 5 different colors which can lit inside or outside the coil. I want to test it mounting them in a rotary plate to see the effect in movement. I also have added a USB-C connector to it for powering convenience.
These are fun. So many possibilities, I just have to decide where to begin.
Very funny device, only improvement can be USB as power connector. My son spends hours moving shining marbles back and forth.
The product works wonderfully well! It consumes from 70 to 80 mA from a 5V source. Each LED's is powered by a small SMD-inductor, which couples to the magnetic field generated by the coil. It is instructive to use an LED-inductor combination as a sensor to visualize the path and density of magnetic flux lines.
It's good but the wireless range is no too much 2-3cm max...
Nagyon jópofa játékszer.
