I've been working for my thesis with Kirlian photography, researching and playing around with every single idea I found on the internet. Most of them required manual switching, 555 circuits or expensive pulse modulators, so I decided to try my own version and design a circuit driven by the Arduino. This schematic can be used in many projects that need pulse modulators and high voltage, be creative and enjoy!


Warning: This is a high voltage project. If you have no experience in this field please don't underestimate it. If you have heart problems, health issues or are pregnant don't try it!!!
I am not responsible for any incident or accident that might happen while you build this circuit. Please note that you should not have any problems if you follow this simple rules, but always be careful.

VIP Safety Rules:

-Wear rubber gloves
-Work with the adapter and battery unplugged at all time.

Don't place your finger on the discharge plate unless you are:

-Insulated from ground (sneakers or any insulating material)
-Tested the device on a ground object

Step 1: Main Schematic

This is the basic schematic, please take a second to understand it before we proceed. I designed it in illustrator because I am a visual designer and can't stand the way schematics look! hopefully you'll understand it better too.

To introduce yourself into the Kirlian concept you just need to know that it's a high voltage low current circuit that releases a discharge to an object or subject when this one is connected to ground. In this case there is a main input that gets released to a transformer and then converted into high voltage. Because I took the switch that controlled this input and the capacitors that retained them out of the schematic we will replace that part with a relay (let's say is a switch that can open and close depending on what we tell it).

A  basic Kirlian circuit needs to work with an automatic pulse modulator that it's constantly feeding and releasing electrical juice. As humans we don't have the ability to turn a switch on an off that fast, so here is were the Arduino comes; It feeds the relay with a controlled pulse telling it to open or close whenever we want.

Using the Arduino for this is a bit overkill (I'm sure you wouldn't disagree), but the build is interesting. Do you have any more Kirlian-photographs to show?<br /> <br /> L<br />
I think the Arduino or similar micro controllers are perfect for this kind of application, if you intend to add a little automation and finesse to the program. I'd say have the controller also switch power on and off to a light source (make the room dark during filming and light when done) and start a run timer for 30 seconds or so, after a brief delay, once triggered, that would stop the process once the time limit is reached.<br><br>Then program a few safeties and an emergency stop tied to a conveniently located button and, viola, you have a pretty slick party favor and maybe a little side hustle at craft fairs and the like.<br><br>All easily written into the existing code shown in this build.<br><br>Just need to add some caps in parallel with the primary and then precisely choose my frequency and this thing can really produce!
This whole thing can also fit into a lunchbox (minus the supply), which is a major plus, and really opens up a lot of opportunities for experimentation due to this portability.<br><br>Honestly, with a bit of tuning and refining, I think you could sell these things for a profit. Let people either purchase or produce their own clear discharge plates or just use them the old fashioned way with photo film and no clear discharge plate, and let your hobby make you some money.
Hi Lemonie,<br /> The process of coming up for this solution was quite long. I did and tested many prototypes to get to this point, so that I could say was an overkill. Building the circuit with the arduino was quite fast and you get much more out of the circuit than by using a regular pulse modulator. As I mentioned to Berserk87, my purpose is to build an interactive sculpture with this schematic so it was really worth it. I will post more picts soon! but not Kirlian ones, I will post from the &quot;Forbidden flower&quot; :)<br /> Thanks for your interest, and let me know if you have any questions!<br /> Cheers,<br /> Denise<br />
Thanks for the details, I'm interested to see more of what it will do.<br /> <br /> L<br />
So this thing seems to work at about any speed and at voltages as low as about 6.5VDC, but only at higher amperages. Those of you familiar with Ohm's Law already knew that.<br><br>I had a steady machinegun rate at &quot;delay(10);&quot; and could not go lower because I blew my SSR with nearly 10A at 24VDC at that speed while running it through my homemade discharge plate comprised of two silicone sealed panes of glass filled woth water and a copper wire running along the inside perimeter within the water sealed between the two panes. The plate works great, actually. I just need a SSR rated at 10A or higher this time.<br><br>Anyway, this works great and a little programming to add the use of switches or buttons to quickly change delay settings or shut off the pulses without having to re-flash the controller or pull the USB makes this an ideal adaptation of this logic for Kirlian Photography.<br><br>I have found that having a smaller discharge plate makes for brighter coronas without needing to increase the output voltage to the plate.<br><br>Are you still using this setup or have you moved on?<br><br>Also, have you tried driving that ignition coil using a micro controller and mosfets in h-bridge configuration? H-bridge in some kind of oscillating mode, but I forget the official name for it, just now. Anyway, it is supposed to be a circuit for changing DC motor direction and is said to be better at driving coils for bigger potentials.
<p>I am interested in knowing more about the possible applications of this device to medical diagnostics. I am the naturopathic/ water consultant advisor to an allopathic medical director who is very much interested in purchasing/creating a device for Kirlian photography and aural diagnostics.What are the most likely costs to be incured in (a) purchasing a camera/device, or(b) building one such?</p>
You cant be grounded !!<br>If you are then you can get shocked as current will pass from HV (glass) through your body to ground. Please edit this step for the people's safety.
Great post! Would you please also post a schematic of this circuit? It's a bit unclear to me at the moment<br><br>that would be great thanks!
In the beginning you say that you need to be grounded as a safety rule, if you were grounded, it would kill you. &nbsp;What i think you meant to say was insulated from the ground, this way your body can reach the same voltage as the discharge plate, yet still stay safe as there is no current passing through you. &nbsp;You might want to revise this because if someone just skimmed through that part they could seriously injure themselves.&nbsp;
Hi Slick36,<br /> You are totally right, I did mean that. My appologies eveyrone, I am editing it right now.<br /> Thanks!
This does what exactly?
Hi Berserk87,<br /> you could see this project as a customizable controlled HV device. For example, I designed it for other purposes besides a Kirlian device. I will use it as the main input for an interactive sculpture in the future. I also made a sculpture from wire in the shape of a flower, that when you touch you can see a spark jumping from your finger to it. There are many things you can do with this schematic, it's up to you what you want to use it for. Usually on the internet you might find people using 555 chips or pulse modulators that are really expensive (some $90) so I decided to use my arduino and have the ability to control also other things such as audio, light and other discharge surfaces all at the same time.<br /> Let me know if you have other questions,<br /> Best<br /> Denise<br />
Im still confused :S<br /> <br /> i'll guess ill have to wait and see the final result.<br />
