Súng Chích Điện Tự Chế Có Pin Rời

To make the stun gun you will need:

• High voltage generator, 56 mm long
• LED and 1k resistor
• Li-ion 18650 battery
• push button(8mm high)
• switch
• Spring with a diameter of 7.3 mm
• A nail or 2 (if choose head 1) with a diameter of 3 mm
• If you choose head 2 you will also need 2 washers and 2 M3 screws with nuts

In head 1 you may need to heat the nails so that they go in well.
In head 2, To connect the wire to the screw, it might be easier to add an insert at the end of the screw and solder to it.

• In the file I uploaded there is a special place to pass the electric wires under the high voltage generator
