Joytech Music Tesla Coil Acrylic Base Shell Arc Plasma Loudspeaker Wireless Transmission Experiment Desktop Toy Model (YS09)

This thing is very fun and thought provoking. I sounds surprisingly well, not that you would use it to listen to music for long but there is something fun about interacting with the music through a plasma ark. So many other little things to explore too. I had seen past reviews saying the music didn't work. I have two audio output jacks on my computer, one worked one did not. I bet it's common. It's made well, a touch on the small side but fun.

is a deadly one.purchased for my brother, the engineer, who correctly; thought it to be a toy and poked it...to find out that Tesla Coils are heart stoppers.havent been invited back, which is fine, since he hasnt been the same since surgery.FOR CHILDREN OF ALL AGES

The media could not be loaded. I wanted a simple Tesla coil to show my AP Physics students when we talk about induction. This is relatively safe and shows the basics of high frequency high voltage. It's about the size of a soda can. It comes with a few discharge tips: a pointy stick like a small nail that screws onto the top (gets hot after 20-30 seconds so don't burn your fingers removing it), a thin wire attached to a small screw that screws onto the top and is loose at the top end so that the plasma can wiggle it around, and a spinner arm that balances on top. The sparks are about an inch long or less and nearly steady - not long bright white sparks like on big Tesla coils, but small purple plasma sparks. Music played via a laptop or phone headphone jack can be heard clearly if the volume is turned way up. A florescent tube lights up in your hand from about a foot away. It came as two main parts: the secondary simply screws onto the base. The base has the primary coil (about 4 turns), the driver circuitry, and a cooling fan. The acrylic parts give it a clean look and allow you to glance at the electrical components.

Bought this for my son as a Valentine’s Day giftIt worked about for about 7mins, connected the Bluetooth &the speaker sounded cheap, it stopped working then it started flashing.There’s no way to control the voltage, I figured buying this more expensive one would be worth it but we are left super disappointed.

I powered the unit with a 24 volt Supply and saw a nice discharge from the needle attachment just like in the photoThe spinner spins and light bulbs place near the column illuminateAnd the clear glass bulb has a nice Corona discharge inside of it when placed near the columnEverything is just as advertised except for the sound I could not get any sound out of the Tesla coilWith the 24 volt Supply powering the unit and the needle attachment in place I connected my wife's iPod and played Alice Cooper at full volume and heard nothingAm I doing something wrong is my unit a dudIf the manufacturer is reading these reviews I would be very grateful for any suggestionsShould I return the unit?

The media could not be loaded. This coil is very impressive. I decided to go with Joytech after reading many good reviews. I also chose this plug and play version rather than a DIY just because I didn’t have time to tinker with a kit. It came well packaged and in perfect order. It’s well constructed and looks great with the acrylic and blue combination. Works as stated, and a definite conversation piece. I used a splitter to add a little low end to the music as this coil acts like a treble speaker. Still w/o an added speaker it’s amazing to hear the music in waves. I used an old nano iPod for source.(*Note the video is without an extra speaker, just the sound from the coil)Best not to put any sensitive electronics in close proximity. While it didn’t damage anything, my T-Touch Tissot watch went wonky but all I had to do was reset it. Now I’m keeping that watch away from the coil while in use. It’ll also light up a variety of light bulbs from the utility drawer.If you’re looking for a prebuilt demonstration coil suitable for young adults as well as us old adults, you can’t go wrong. Definitely recommend!

Very weak discharge. No adjustment for frequency.

This is a very well made product. Everything is encased in clear plastic for protection, but yet you can easily see the guts. This is a fantastic desk piece and conversation starter. I love that it came with several accessories for demonstrations. The music feature works, but you do need to turn the volume on the MP3 player to max for the Tesla to play the music. No assembly was required. It was really well packed for shipping protection. I note that Joytech post a lot of very similar Tesla devices and their advertisements really do not distinguish between the various models. This was the most expensive of their options. They really need a table showing how the various models differ. This is a small tesla coil so while the sparks are quite visible they are only about an inch long. This is a relatively low frequency Tesla coil so touching the sparks could be painful. I have a much larger tesla coil which operates at a higher frequency and with proper technique I can safely touch it. I am reluctant to try touching the Joytech Tesla coil.
