From the KS-001 kit, we can build a mini Tesla coil that generates an electromagnetic field around itself, causing the glimm lamp filled with noble gas (without an external power supply) placed in its immediate vicinity to light up in our hands.
Its main parts are the printed circuit board and the output coil.
After soldering the hole-mounted parts and installing the spacers, solder the pre-tinned wire of the output coil to the designated place, and then stick the output coil to the printed circuit board as shown in the picture.
It can be operated from a power supply or battery.

Specifications:

- Operating voltage: 9...12V DC
- Connector: 5.5 x 2.1mm
- Maximum current consumption: 660mA
- Preparation time: 15 minutes
- Dimensions: 40 x 31 x 49mm

For assembly you also need:

- soldering iron and tin,
- side hip pliers,
- Phillips head screwdriver.
