If you choose the kit, you need to solder it yourself.
no battery
This low-voltage electromagnetic gun uses 3~5V power supply and can use 3 AA batteries
Or the mobile phone charger is used as the power source, and the boost module is an integrated structure with
The advantages of simple assembly, stable work, fast charging speed, etc., energy storage capacitors are used
Large-capacity capacitors, with special transmitting coils, long transmitting distance and no noise
This electromagnetic gun has an input voltage of 3-5V, a launch voltage of 25V, and a launch distance of 5 meters.
On the right, the shell uses a 3*20MM iron cylinder, which has a good launching effect and is safe
And other advantages, very suitable for electromagnetic experiments in primary and secondary schools
Instructions:
1. After the welding is completed, check the drawings to check whether the components are installed correctly, especially the polarity of the electrolytic capacitor, and the switch direction cannot be installed in the wrong direction.
2. After the installation is correct, adjust the potentiometer on the booster board clockwise for 25 turns, and adjust it a few more turns until it clicks at the end. At this time, the boost output terminal is the most
The high voltage is 25V. 3. Connect to the power supply and use 3 AA batteries 4.5V or micro usb mobile phone charger 5V power supply (cannot use power bank for power supply
If the battery does not move), after charging for 1 minute, the red light will light up and the charging is complete, and the shells are loaded into the tail. Press the switch quickly to release the shells.
After the switch is released, it will automatically charge again. When the red light is on and the battery is fully charged, it can continue to transmit.
4. The red wire of the emission voltmeter is the positive pole and the black wire is the negative pole. They are respectively connected to the positive and negative poles of the energy storage capacitor to display the emission voltage. Please do not reverse it.
catch.
5. Since the coil and the barrel are tightly matched, please install the barrel on the coil first and then install the coil on the PCB board! You can also try the barrel first
Whether it can be installed into the coil and then decide how to install it. If you encounter that the barrel cannot be installed in the coil, you can first polish the burrs on the 2 ends of the barrel and add some lubricant (or
(Peanut oil) lubricate it, and then push the coil harder.
Regarding range:
1 The launch distance mainly depends on the launch angle. According to the ballistic formula, the projectile has the farthest range when fired at a 45-degree angle.
2 The position of the shell in the barrel also affects the range. The best place to put the projectile is to keep the head of the projectile flush with the tail of the coil. In this state
The farthest range, if it deviates from this position, the range will be significantly reduced.
