1.Introduction:
HU-064 is a DC 3V High Voltage Electromagnetic Transmitter DIY Kit. It can simulate an electromagnetic transmitter and convert electrical energy into magnetic energy, thereby injecting a metal cylinder. Users can use it to learn and understand the working principle of electromagnetic transmitters and learn the basics of electronic technology.
It is a very interesting DIY electronic product which enables users to understand the circuit more clearly and learn soldering skills.

2.Feature:
DIY Soldering Project: The DIY soldering kit is used to installed to an interesting mini shooting game kit which can shoot small cylindrical metal at short distance. The working principle of this shooting kit is: use the ampere force generated by the electromagnetic field in the electromagnetic system to accelerate the metal rod. It is really a great DIY electric kit, you will will be more familiar with electronic components and learn more interesting electronics things. Great for electronics hobbyists, beginners, school and home education.

Easy to Assemble: During the assembly process, the kit requires not too much soldering, more needs to connect the circuit and assemble the components. We have prepared a detailed user manual. The connection was clearly mapped and labeled on the board, and the principle is simple.

Please Pay Attention:
1>.Do not touch the metal parts with your hands when it is charged. The finished project is a device that works under high voltage. Although the energy is small, and the insulating plastic shell guarantees its safety.
2>.Please discharge the energy storage capacitor before troubleshooting. Please refer to user the manual for detailed discharge operation.
3>.Children under the age of 14 need to be installed and used it under the supervision of an adult.

Installation Manual:

4.Instructions & Steps for Usage:
1>Turn ON black power switch to charge the capacitor;
2>.Wait for approximately 10-30 seconds to complete charging and the blue/red LED is charge indicator and slowly brighten up;
3>.Insert the metal cylinder from the rear end of the plastic tube, and its tail should be flush with the tail of the tube;
4>.Press the launch button (red button), the metal cylinder will fly out, and the launch is complete.
5>.Warm Tips:
1>. It can be launched once each time, and after the launch is completed, it needs to be recharged.
2> Relax as soon as possible after pressing the launch/red button.

5.Notes:
1>.The instantaneous voltage inside the circuit board reaches about 210V, so please don’t touch component during charging.
2>.Do not wear or damage the insulation layer on the surface of the wire.

3>.The capacitor must be discharged first before circuit testing. The capacitor has been discharged if the blue indicator turn OFF.
4>.Its power consumption is relatively fast, the working voltage is about 50mA when charging, so it is recommended to use a new battery.

5>.Its working voltage is 3V, so the input voltage must not exceed the working voltage.
6>.It can be launched once each time, and after the launch is completed, it needs to be recharged.

7>.The launch distance is related to the horizontal position, Iron Pillar’s position and many other factors.
8>.Before stopping use, it is recommended to fire several times to release the electric energy inside the capacitor.
