Item Description

Product Feature:
 
Mini Magnet Shooting Kit: The welding practice kit is a very interesting project and a great desktop toy. The coil gun can display electromagnetic force well and can shoot small cylindrical metal at close range.
Easy to assemble: This kit can usually be easily assembled. If it cannot work after welding, please contact us for support.
The working principle of this shooting toy is to use the ampere force generated by the electromagnetic field in the electromagnetic system to accelerate the metal rod. When assembling, this is a very interesting toy and a good lesson on small circuits and assembly.
High integration: We concentrate all components on one circuit. This product has high integration and is not easily damaged. This greatly simplifies the difficulty of assembly. Even the parts are simple.
【 Warning 】: Do not touch metal parts when starting up!!! The project is being carried out under high pressure
 
Product parameters:
Power supply voltage: 4.5V (3 No. 7 batteries, all packages shipped without batteries, parents need to bring 3 No. 7 batteries)
Range: 6-8 meters;
Usage: Move the switch to the left for charging, and the green and colorful lights will light up during charging. The voltage at the capacitor 2 terminal will gradually increase to around 90V, and the charging indicator light will light up. This is to turn the switch to the off end, and then press the red emission button to launch.
The power is relatively small and suitable for experimentation. Although it is relatively safe, do not point the barrel towards weak areas such as the eyes during shooting. Children under the age of 14 should use it under adult supervision!
Advantages Introduction:
1. The charging speed is fast, it can be fully charged in 10-20 seconds (the new battery charging speed is relatively fast), and there is no need to rest after launch to continue charging and use.
2. The circuit board is already wired internally, and buyers can simply solder or attach the corresponding devices according to the device symbols and parameters printed on the circuit board, without the need to connect the wires themselves,
The finished product is simple and beautiful, without Spider web like wiring, so it is relatively simple to make and has a high success rate.
3. We used a machine to wrap the launch coil before shipping, which saves the buyer from wrapping the launch coil themselves. The transmission coil is wound 400 times with 0.49mm enameled wire. If it is manually wound, it will fall asleep from 1 to 400 times, which is very annoying.
Tools that need to be provided by oneself:
The buyer needs to provide the following necessary tools and materials: soldering iron, soldering tin, glue gun, glue stick, and water nozzle pliers;
