Mini Tesla Coil Diy





Introduction: Mini Tesla Coil Diy

About: i like diy,this site is so great!

this is a simple tesla coil diy project,based on Single self (A triode and some of the coils produce oscillations and then generate high voltage),use a DC 12V power suply can star it

Schematic diagram almost the same as the picture

it can generating electric spark,aslo you can put a metal ball on the top,then it can light fluorescent lamp

Step 1: Welding Resistance and Capacitance

one is 1k,another is 10k,Welding according to the label on the circuit board

Step 2: Two LEDS

the long foot of the LED is "+",the short foot is "-",welding Accord to the label “”+“”on the circuit board

one LED is for Power indication,another is for showing the working state of the Tesla coil

Step 3: Power Outlet and Switch

Step 4: Triode

Step 5: Secondary Coil

you need Use a knife to scrape the surface of the paint,Otherwise can not conductive

at last need use glue to fix it on the pcb

Step 6: Four Foot

Step 7: Power On

12v power

if the Welding is all right,two LEDs light and on the top,there is a spark

Step 8: Non Essential Steps

if you want put the metal on the top,aslo need Scrape the surface paint,then use the Copper paper fix the wire on the metal ball

Step 9: Enjoy!

Does anything attach to L2?

it is not Ordinary light bulb, it's neon bubble,so is not your power problem,and if you want to To light toilet paper, you just need to remove the metal ball and let the arc out

Our kit has 2 of exactly the same resistors, Red Blue Blue Red Red. Has anyone else enountered this?

L1 is missing and the direction to install it is not in the mini tesla coil diy direction that I printed out. I went back to the page and I stall can not find anything about l1. Can you please putout the info for L1.

L1 is in the board

I managed to get the kit but there is no lead for the power nor is there a power supply. I do have the socket that needs to be soldered to the board but what is it we are supposed to use for power? Is that missing from my kit ... I have the Mini Tesla Coil kit

use any DC power (voltage 12v-24v.current 1A-2A)

As a point it would be nice to have a sheet that inventories everything that should be in the kit ... or even a photo with all items arranged and visible.

I got to the coil portion of this guide and when I went to take the bottom wire and begin scraping it, a light pull ended up detaching the end of wire coming out of the bottom of the coil.

Any suggestions at this point as to how to remedy this? There is only a small portion of visible wire where it was detached from. Am I able to solder the detached piece back together?

if you mean it broken on the bottom,it is easy fix it,first you need take off the White tape,and use your Finger hold copper wire(IMPORTANT),then Take off a circle,and put the tape back,done!

Thank you for the response, I will try this tonight once I am off work.

you mean the wire Broken on the bottom?

how do you tell what is a 1k and 10 k resistors? and where are the wires from the coil do i unravel some from the coil?
