Mini Tesla Coil Kit, BD243, DIY Electronic Project, Hand Solder Practice, No Battery Required, Non-Laser for Hobbyists

A set of components for a Tesla coil kit that you need to weld and assemble on your own. Tools needed include a soldering iron, glue gun, and water pliers. The input voltage should be between 9-12V; you can start with a 9V battery, but if an arc appears, the working voltage should be 12V.

Remove the protective paint about 3mm before reaching the end of the coil welding wire. This step is crucial. Ensure it is removed. Don’t forget.

The 10k resistor should be mounted vertically, and the capacitor should not be polarized. The transistor and heat sink should be screwed and mounted. One end of the secondary coil should be connected to T4 by welding, and the other end should be left hanging.

Position the coil precisely between the two white circles and secure it with adhesive. Avoid contact with the coil while the power is on and the heat sink is in use. Keep in mind that prolonged operation may lead to excessive transistor temperature and product damage.
