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

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.

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.

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!

I bought this for my son for a school project. He loves it. It came with 3 tips: ion powered spinner, spinning wire, and standard sharp tip. It lights up LED lights and florescent bulbs wirelessly from a few inches away - kids love this effect. We ran it at our kitchen table for about 5-6 minutes total, and we started noticing a strong ozone smell. Soon I had a headache and my throat was scratchy - ozone overdose! Ventilated the room well and all is well. Even when running this for about 30 seconds I notice a very strong ozone smell. Make sure that you use this in a well ventilated area due to ozone production! I tried the audio input, and it works well - novel, but not worth it as a speaker due to ozone production.

Junk. Worked for about 10 minutes.

I originally bought a different brand unit which broke but a replacement wasn’t in stock for 2 months. I thought this would be comparable and this one is actually slightly more expensive than the other brand. I got the Bluetooth enabled unit.The power level is so low, there’s no arc at all, just a kind of fuzz that emits from the needle. It barely lights the bulb it comes with using the needle top. The spinning toppers that it comes with look cool, but they don’t make up for the glaring issues with the product.This is *not* a plasma speaker/singing Tesla coil. There’s an actual speaker in the unit and the plasma barely moves in response to the sound. This is an expensive toy wrapped up to look like a decent Tesla coil.If you’re looking for a cool desk toy or unique gift for someone, this works. But a true geek would be disappointed in this unit.

The media could not be loaded. I am a middle school science teacher and this is perfect for my demo on electricity. I just got it so I can't speak for how durable it is, but putting it together was easy... just screw the coil in to the base. The power supply is a little cheap but unlike a lot of these tiny tesla coils this one at least has a built in on-off switch.It comes with a balanced spinner to show how streams of electric charges can push a physical object, as well as a pointy spike top, and a ball with a soldered wire top. It also comes with a packet of lamps to demonstrate wireless energy collection, as well as a cheap but perfectly good earphone cable to connect a sound source for the plasma speaker effect. The heat sink seems adequate, and this model has the plastic housing to keep you from accidentally touching it. I let it run for a good 2 minutes or so with no issues. See attached video to get a look at it in action.

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.
