Introduction: Mini Tesla Coil Diy

Picture of Mini Tesla Coil Diy

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

Picture of Welding Resistance and Capacitance

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

Step 2: Two LEDS

Picture of 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

Picture of Power Outlet and Switch

Step 4: Triode

Step 5: Secondary Coil

Picture of 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

Picture of 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

Picture of 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!

We finished making ours and it works great with the small bulbs shipped with the kit. However we cannot get a normal sized bulb to light, as in the pictures. Nor can we get a napkin to set fire. :(. We are running a small power supply - 12v out at 1 Amp. Do we need a 2 amp source to get the bigger bulbs to light? Any other thoughts? Thanks, Scott

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

Is this from a kit? If so, where do you get it.

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

what is the name of the kit, an a link to order it would be ji

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.


Minil2 (author)wlhank2017-04-12

L1 is in the board

ChéC6 made it! (author)2017-02-27

It was an uphill fight, but! I did it and my friends and LOVE it! This was a lot of fun building it. thank you!!

TimothyR54 (author)2017-02-25

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

Minil2 (author)TimothyR542017-02-26


Minil2 (author)TimothyR542017-02-26

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

TimothyR54 (author)2017-02-25

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?

Minil2 (author)VicoB22017-02-13

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!

VicoB2 (author)Minil22017-02-13

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

Minil2 (author)VicoB22017-02-13

you mean the wire Broken on the bottom?

thomasandruby (author)2017-02-03

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?

Minil2 (author)thomasandruby2017-02-13

google Five color ring resistance identification

thomasandruby made it! (author)2017-02-04

we figured it out!

I did not have the red button part though there does not seem to be a place for it nor the feet, although there is not a place for them either. Also, the power conector does not say what to do with the third (ground?) connector, nor is there a cord for the plug. it was a mini tesla coil that I purchased, Also, with out instructions I assumed that one of the end of the coil wire gets soldered to the center whole, and the other end goes to the outer whole. I have it drying with the glue now but Im sure I did do it correctly. At least I can't tell till I get some power!!

GordonB35 (author)GordonB352017-01-22

Banianji pointed me in the correct direction, I have to redo my coil connection but everything else seems correct.

banlanji (author)GordonB352017-01-21

maybe yours is the old?

GordonB35 (author)banlanji2017-01-22

Thank you, you were correct, I had the Micro not the Mini.

edcalles (author)2017-01-20

In the schematic provided, where is the 1k and the other LED? how do they are wired?

banlanji (author)edcalles2017-01-21


edcalles (author)banlanji2017-01-21

Many, many thanks

edcalles (author)2017-01-20

Can you please provide an updated schematic? Can you please indicate where is the primary coil and the secondary, how does the 2 LEDs are connected with the 1k resistor? It will be much appreciated. Thank you.

I received the kit from Aliexpress. Instructions were clear except the polarity of the DC power jack were not clearly stated. I nearly shorted it out by reversing the polarity. The center plug of the jack is positive(+). The sleeve is negative(-). Fortunately I did not harm the circuit. It draws about 400 mA at 12VDC. It functions exactly as depicted in the Instructable. FUN!
