Joytech Music Tesla Coil Acrylic Base Shell Arc Plasma Loudspeaker Wireless Transmission Experiment Desktop Toy Model (YS04)

Fun and new little device, can burn so follow instructions. Would not allow young children to utilize, even with direct supervision.

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!

It worked for a few mins, then it shut off and won't start back up. I thought maybe it over heated but hours later, still nothing. It's looks cool but it's definitely junk.

I'm impressed! This little gem is well built and performs. Whoever designed the packing and packaging did an amazing job. It arrived undamaged and ready to go. I got the one with Bluetooth connection. It was brain-dead simple to setup and use. I look forward to using it in my physics classroom.

Bought this for my husband. He loves showing it off. It should not be operated for more than 20-30 minutes at a time, because it does heat up. Some reviews downgrade the review because of this, however all Tesla coils will do this. I would like to see an operation manual provided to help educate those who don't understand precisely how delicate a Tesla coil can be. If a manual was provided, I would have given 5 stars instead of 4. Otherwise, great product and worth the price!

This is a cool little Tesla coil. A good learning tool that also adds decor to your living space and a conversation piece. Shipping was really fast as well. It was a bit disappointing to find out that the power supply/transformer didn’t work right out of the box. Excitingly Wanting to play with it, I was able to find another 24v power supply that just needed the plug wired on. So besides the junk 24v power supply it came with it’s a fun little unit.

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.

Came fully assembled but the packaging on the one I got was a little loose and the coil had come loose. Corrected this, plugged it in and played a song over the thin wire top piece. It was very cool and I wanted to show everyone but by the time they came into the room to see it stopped working. The blue LEDs stayed on but the top spark stopped. Very disappointed I had to return it as defective, it was so cool when it worked. I am torn because I really want one now but am worried if I bought it again the same thing might happen.

The spinning windmill attachments didn’t spin for me… a little disappointed. And Bluetooth didn’t work either.
