About this project
The project is near completion. Thank you for the support. We will continue to post project updates at www.teslatronix.com until we have fulfilled all our backers! Once all the obligations to our backers are fulfilled, we will start to offer kits directly from the website.
True wireless transmission of power is possible, it is here, and it is simple! Admittedly, the production value of these videos is sub par (all were created as mere demonstrative videos for the public), however the results speak for themselves. All completed Tesla Tronix Tesla coils will have included wooden bases. The coils featured in these videos are for demonstrational purposes only, and are not finished products.
When people think of a Tesla coil, they think of a device that is designed to transmit power wirelessly. The Tesla Tronix Tesla coils, loosly based off a slayer exciter circuit variant require no capacitors, no spark gaps, and no AC power source to function. In fact, the Tesla Tronix Tesla coils can be powered off almost any DC power source from 5V-35V, with a current draw far less than one amp, and in most cases, between 250ma and 700ma. So what does this mean? Anyone can now fully enjoy and study the properties of a traditional Tesla coil, without the cost and complication in doing so.
These Tesla Coils resonate well with LED lighting and Florescent tubing. With proper grounding at the receivers, usable current can be extracted right from the air around you!
The range of these tiny DC, solid state Tesla coils is phenomenal. Be prepared to be able to light florescent tubes from over 5 feet away!
There is a wide range of potential applications for such a device, as demonstrated in the following video:
In this video, I use a mere 9V battery from my smoke detector to provide candle light in my dining room during the hurricane Sandy power outage this past fall.
So what exactly drives the coil?
A handful of components are responsible for the "magic" behind this circuit. Any DC source fed to V + and - as low as 5v 100ma can power these circuits. Let's say you wanted to use your laptop charger to power the coil. Average current draw from your average 19V laptop charger would be 600mA(or less) at 19V. The charger can provide about 4 amps (depending on the type of laptop charger) but in reality it needs less than one amp. So any DC source to about 30V at 1A can be considered safe with a good heat sink on the transistor.
The final product will consist of 5 main components, each will be interchangeable with different lengths of L2.
Toroid: The top load of the solid state Tesla coil. This is the antenna through which the majority of the power will be out-put from. It looks like a coil, however both ends of the wire are soldered together, making sure a voltage difference of 0V across it. The more copper on the toroid, within reason, generally will improve the output distance of the coil. The Tesla coil will in fact function without a torrid, however the output will be dramatically decreased. The wire toroid design may be substituted for one of a more traditional design, or may appear different than in the videos, but will serve the same function in the end. This is also a testament to the robustness and flexibility of the circuit overall.
L2: The L2 can vary in the number of windings from 500 turns all the way up to 2500 turns and beyond. The more turns on L2, the higher the final output voltage, and the longer range you should expect from your Tesla Tronix Tesla coil. Wire, when stretched out in length, has a resistance. Too many windings, and the circuit will not perform optimally. 2500 turns is approaching the upper limit, but winding a larger one and experimenting with it couldn't hurt! All Tesla Tronix L2s will be lacquer coated for durability, and to prevent ambient temperature differences from unwinding the coil due to expansion and contraction.
L1: The L1 also dictates the final output of the coil. The fewer the number of windings, the better for this coil. As low as 4 turns on the L1 have been effective with a 2500 turn L2. Too few turns for too large a coil will result in difficulty in getting the circuit to resonate.
The board: As stated previously, the board that drives the entire circuit only consists of 4 main components: A resistor, transistor, and two diodes. There will also be terminals on this board for the connections for V+ and -, L1+ and -, and a terminal for a connection from the base to the bottom lead of L2.
The base: A nice wooden base will be the platform upon which the erected Tesla coil will sit. A notch will be cut into the base so the circuit board can be oriented in such a way to allow a wide range of heatsinks for the transistor.
All complete Tesla Tronix Tesla coils will be fully tested before shipping. Batches of L1s and L2s and toroids will be paired for optimum performance. Considering that any particular board will drive any reasonable combination of L1 and L2, there is no need to have different board types for the different coil combinations.
Each individual component can be manufactured on an individual basis, then mated to the other 4 main components based on the order. A serial number will be assigned to the coil and placed on the 5 major components and the circuit will be ready to ship. For coil/kit combinations, only the L2 will receive a serial number.
These coils are perfect for the educational sector. Students can be instructed to assemble and document their findings related to these devices. The simple construction, design, and low component count achieve exceptional results, yet will engage students directly in a fairly un-known realm of technology. An anomaly as far as traditional electronics kits are concerned, a new project with exciting (and possibly limitless goals) will easily draw the attention of your physics, math, electrical and general science student.
If you or someone you know is an electrical hobbyist of any sort, and are looking for something new, this is the project for you! I have yet to find one instance in where an individual only stopped at one coil. The possibilities are limited to your imagination!
Everything will ship from Allentown, PA with all items aquired from the United States and around the world. Your Tesla Tronix Tesla Coil will be hand made in the United States and shipped from north east Pennsylvania. A small friends and family team comprised of engineers and skilled craftsmen is standing by to take initial orders. With your support, we will be able to take our concepts to the next level.
As with any traditional Tesla coil, the risk of minor shocks and burns are present. However, unlike other Tesla coils, this type is safer in the sense that outright electrocution is near impossible. However, This device does operate at frequencies between 540Khz to about 1.5MHz .
DO NOT use your Tesla Tronix Tesla coil near any sensitive electronic equipment while in operation, this includes but is not limited to: cell phones, MP3 players, laptops, tablets, cameras, computers or any other low voltage or electrostatic sensitive devices.
Tesla Tronix is not responsible for mishap or misuse of this, or related devices.
BE WARNED. YOU WILL HAVE FUN with a Tesla Tronix Tesla coil.
Risks and challenges
We have various distributors from all over the world for the specific components we need, and have tested several of these distributors and have had a 100% success rate for acquired items. In addition, the circuit and its construction are versatile enough that there are several interchangeable components should the supply of one specific component become interrupted. Bulk manufacturing processes for the L2 are ready to go, hand production of the circuit boards can be scaled based upon demand, however this is the internet and the best-laid plans of mice and men oft go astray. Our original group of backers can rest assured that their items will be received within the reasonable time frame allotted, and any setbacks will be directly communicated to all those involved with the project. If the demand exists, TeslaTronix will be continue to produce product on a more sustainable schedule. A website is in the works which will be a portal for all things related to these circuits, and other similar DIY projects!
Again, these are experimental devices. Extreme caution should be used when developing or running these devices. These devices are not intended to replace any commercially available product, and are for experimental use only.Learn about accountability on Kickstarter
Hey there, I'm an international backer as I live in the UK. Will I need to add anymore for postage or is it included in the $75 ?
The international kit includes shipping costs. For our international backers, our shipping estimates were for much fewer than expected total packages to be shipped. Though not a promise yet, we MAY be able to accommodate a few extra goodies for our international backers- possibly extra transistors or other components. We understand high cost of shipping, and when the project finishes, we will reassess the situation to provide the best solutions for our backers.
At this time, it would appear that there is only about a 15% difference in shipping via USPS from my location to lets say Alberta CA, or to a destination in Australia.
As mentioned in the comments or FAQ, we know that international shipping is costly, and we are looking into awarding our international backers with perhaps extra components to help ease the blow for shipping. A $50 kit that can potentially cost $25 or more to ship in bulk leaves us with very little margin for error. From our perspective, it is best to over estimate and then over reward in the end if possible, than it is to underestimate and lose.
Hey man, this is a great project. Is there anyway to use this device to power house hold items or electronic devices? do you have some sort of "wireless power antenna" or something along those lines that can hook into places where the power supply is? th
This is only the transmitter so to speak. Others have used bridge rectifiers successfully in part of their receivers. Check my website under "tesla powered house" mongrelshark, from Australia successfully charges capacitors from the next room over from the transmitter.
This is also the point of the entire project. Individuals will be able to design different types of receivers, ect.. to fit their applications.
Hello TeslaTronix, I just recently saw your fundraising project and thought the idea was spectacular. I'm currently looking at donating 200$ and I intend to build and then donate the coil and the remainder of the kit to a local school's physic's departme
(RETURNS, EXCHANGES, SUPPORT WARRANTY INFORMATION)
Kits specified to be complete, are complete, and have the required components necessary for operation. 9V batteries will also be supplied where specified, however any DC wall transformer around 1 amp up to 20 volts (and higher) with a good heatsink on the transistor can power the circuit.
The reality of the situation is at this point, to guarantee full live support at this time would be unfair. At this point it would seem that there will be many backers, many more backers and individualized troubleshooting and support will be difficult. However, A website is in the works which will be a compilation of construction and troubleshooting techniques. After the initial dust settles, I will launch a store portion of the site which will include replacement parts including transistors, however all kits and coils will be sold on an "as is" basis, with no expressed warranty. Due to the nature of the device itself- being able to produce arching, and the ability to use various DC input voltages and sources, I cannot offer any type of returns because there is no specific intended use for these devices other than more research in of itself.
These are experimental devices, and should be treated as such. These are also simple devices to build; if a component may become damaged in the future a substitute component can easily be found. A compatible transistor cross reference list will be provided. Personally, I have not smoked a single transistor to this date, however there are other individuals I am aware of that throughout their journey have smoked a handful.
All that being said, as time progresses and the dust settles it may be possible to reach out to certain individuals/groups for some limited support, But as an initial backer you are actually becoming part of the first wave of individuals to lay their hands on such a product, and I would like a DIY community to bud from it.
What electronics should I be careful of? For example, my desktop PC, can I turn it off and then power the Tesla coil? Big fan of Tesla, and now of you; going to be a backer shortly. Last question. That sphere, is that the one in the Kickstarter update?
Yes it is recommended that you not use your Teslatronix Tesla coil near any sensitive electronic devices. Even if it is off, it is probably not a good idea. Truth be told I have operated my coils near my computers and other things, and the results are not pretty. Anything with a capacitive touch screen (most cell phones now a days, laptop touch pads) will cease to respond and have to be rebooted. The LED lighting on my keyboard will blink if I have a coil fired up within a good 5 feet of it. It is best to use your coils away from such devices when experimenting with them. Placing your coil several feet away from sensitive electronics in a large living room should also be fine as well. Be mindful of your friends' cell phones when they visit, if you decide to show off the coil. Make them put it in another room so they don't inadvertently start tapping it when they are next to the coil.
The spheres included will be a 4 inch version of the ones featured in the video, so yes!
Yes they will!
