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

A++ Recommendation - A beautiful music Tesla coil & eye-catching item that works well out of the box and that it takes less than a minute to assemble. Major attention getter. Well designed and attractive with high quality electronics and very well priced. THANK YOU JOYTECH for building this product. It is a great item to show physics students about Tesla coil designs and concepts as well as getting kids excited about science. Considering the size, the sound is very good (for a musical Tesla coil) but don't expect a high volume. All in all, you will not be disappointed. Everybody who has seen it at my house has loved it. Have fun! A++ recommended.

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.

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.

It arrived broken with the secondary coil tube separate from the main body. This was the second unit I received in this condition. Luckily, this one had enough wire that I was able to resolder the coil wire and stick the coil tube back on. After it was repaired, it worked great. Very pleased with it now. Sends purple sparks out the top and I can smell the ozone that it produces. (Use in a ventilated area) I have not tried the speaker function yet. I’m happy with the product, BUT they need to work on packing it better to prevent damage during shipping. I gave it 4 stars for this reason, otherwise I would have given it 5 stars.

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.

Quality is terrible. The sound is awful. It stopped working entirely after the third time turning it on. I hoped it was a plug issue. It wasn’t. I’ve used coils before with noble gas tubes to demonstrate electron excitation but this one was weak and after taking it apart at the base to diagnose the issue it was junk reused parts that were not assembled to last. I got what I paid for. Now I have e-junk and scraps.

I used it 3 times and was amazing as shown in the photos. The problem is that the 4th time, the cable was very hot and I suspected that the power supply was broken. I purchased another power supply wit the same volts, that means 24v output and when I plugged it it BUM! and a piece of plastic jumped around the room. I guess it was part of the Transistor. Will be nice if the provider will give a recommendation in how to fix it. Its so great that I want to repair it but not sure how.

Would buy again. It does get hot to the touch. The kids love it
