.Scientific Toys: Including shell stand and 12V power supply, using plug-in components, need to be assembled by yourself. Provides tutorials and techniques. It is an extremely cool technological ornament on your desk and an excellent teaching aid for physics and electromagnetic experiments.
.Principle: The pull-up magnetic levitation is mainly composed of coil, magnet, bracket, Hall sensor and drive circuit. When the magnet is close to the Hall sensor, the Hall sensor senses the change in the magnetic field and outputs an analog quantity to the amplifier circuit for amplification. This value is used for pulse width modulation. When the magnet and suspended objects fall away from the sensor due to gravity, the sensor outputs The value increases the duty cycle of the voltage on the coil, and the magnetic force of the coil increases, thereby pulling the magnet and suspended objects. Conversely, when the sensor is very close, the output value of the sensor reduces the duty cycle of the coil voltage, and the magnetic force of the coil is weak. Magnets and suspended objects rely on their own gravity to move away from the sensor. By continuously adjusting the duty cycle of the coil voltage, the magnet objects are suspended.
.Placed Suspended Objects: First connect the power supply, then hold the magnet and slowly approach the coil from below the coil. When the distance is 2 cm, the attractive force provided by the coil can be sensed, and then let go after it stabilizes. If the magnetic force is not enough, you can adjust the circuit The blue adjustable resistor on the board is used for debugging, clockwise is to reduce the magnetic force; counterclockwise is to increase the magnetic force, the magnet should be adjusted to the best position, the magnetic force should not be too large or too small, just can pull the magnet. , Otherwise it will jitter.
.Note: Do not allow the magnet to be attached to the coil when the power is on, otherwise the circuit board will be easily damaged. Unsuccessful release of the float for a long time will cause a large instantaneous current inside the circuit board, and the temperature of the transistor and coil will increase. It is recommended that if the float is not successfully released for 8 times, unplug the power supply and try again after cooling down. Keep magnets away from electronic devices such as mobile phones and computers.
.Creative Gifts: Teaching aid models suitable for students and teachers, as well as excellent toys for technology enthusiasts. As a creative surprise gift, give it to family and friends.

Fun Bath Toy - Loud Squeaker
Size: Small
My dog loves these little squeaky toys. The squeaker is loud and the toy is very durable. She can chew on it and it still looks the same. We love to add them into the bathtub when it’s time for a bath to make her less stressed. She loves to bat them around the house. They roll around pretty well.

Good quality for the price, I’m very happy with this purchase.
Size: Small
They’re slightly smaller than a tennis ball, lightweight, and have a nice bounce. My dog is medium-sized (about 68 lbs) lab mix, and these work great for her.
I’ve been looking for a toy like this for a long time. It’s made of soft rubber/silicone and squeaks with very little pressure, which is perfect for my dog. She loves to gently carry toys around the house and yard, and most squeaky toys require too much force. These are easy for her to squeak and just the right size to carry.

The best new toy in years! 🧡
Size: Small, Size: Small
I opened the package and took out the peach toy for my 7 pound nine year old Yorkie. Needless to say, the floor is already covered with a dozen other toys. When he touched this toy with his nose, it somehow started spinning around. He backed up and then swatted it with his paw. It rolled about three feet away. He has been playing with ‘peach’ for about 25 minutes nonstop, so I had to interrupt my busy day to write this review. I have not ever seen him love a toy this much. Now, it is squeaking pretty much nonstop, and he is still picking it up and tossing it. It is the perfect size for him. It’s a great deal too, with four similar toys in the package.

An instant favorite for my one year old pup!
Size: Small, Size: Small
I came across these randomly while looking for presents for my one year old 10lb chi-mix. I gave her one to start with just to make sure it wasn’t flimsy & she wasn’t going to destroy it because she is definitely a chewer. She was instantly OBSESSED! These are now her most treasured squeakies. They’re the perfect size for her too and I’m happy to say they’ve held up well to her pouncing/jumping on them constantly. They’re definitely not quiet but we get an absolute kick out of watching the way she plays with them. If I could give 10 stars I would. Almost two months later and the novelty hasn’t worn off to her. I’ve saved them to my lists just in case we ever need to replace them for any reason. I’m not sure she’ll ever love a toy as much as these
