Introduction: Simple Mini Tesla Coil
this is a very simple project,mini tesla coil
47k replaced by 10K,others almost the same
Although small, but can emit electric spark
Step 1: Use a Knife to Scrape Off the Surface of the Paint
1.Cut off long legs, keep them about 5mm long
2.Use a knife to scrape off the surface of the paint
Step 2: Welding Primary Coil
the primary coil high about 3mm,so i find a 3mm thickness wood,put it under the coil,it is Convenient for me to weld
after welding,need a little adjustment, make it very round.
Step 3: Welding LED
the LED can show the Working condition of the secondary coil,and aslo make this project more beautiful
Please pay attention to the direction of the positive.
Step 4: Welding the 10K Resistance, Capacitance, Switch ,The Power Plug
Step 5: The Triode
before welding the triode on the pcb,i put it together with the hot sink first,then welding it on the pcb,at last Tighten the screws
Step 6: Welding Secondary Coil
before welding,Scrape the surface paint
then welding to the "L2" pad on the PCB
use screw fixed the secondary coil
Step 7: Finished
find a 12V DC,have some test,it work very well,can light some neon bulb
We have a be nice policy.
Please be positive and constructive.
