ISolderStore DIY Mini Tesla Coil Kit 15W Electronic DIY Kits Mini Music Tesla Coil Plasma Speaker Soldering Practice Kit DIY Soldering Project for Teens Kids Adults Thanksgiving Xmas Gift

Pretty good little kit. I have not soldered anything in over two decades but the kit was easy to build. Instructions were very clear (pictures helped!) It took about an hour to build.Some of the connections are very close together so there is some precision required (and a good pair of glasses!).It works as advertised. There is a little arc that is visible even at daytime and is powerful enough to light a little LED about an inch away from the coil. I was not able to light a larger led bulb.The heath sinks get really hot real quick and so does the coil. My only concern with the device is that the hot coil could burn the insulation of outer coil and somehow cause a short.All in all a good stem project that works.

This DIY project kit comes with all the components. It has resistors and all things needed to create a tesla coil with can produce arcs and music etc. The instructions are online and learning how to solder components and create a product. The size is great and it is a different kind of fun. It's function is to produce sound and arcs. Overall it's a great value for my money. It's functionality is to create a learning situation and fun.

Let me tell you got a story about this thing, so me and my son put this thing together and by the end of it we were ready to put it into a power source, tell me why these people want you to buy the thing that powers this product separately and directly from now. Why would you sell a product that cannot be used after you bought the kid that is supposed to make it work don't get this, and actually I will go further and say I recommend getting solder kits that use a AA or Triple A or whatever use and discard source as power source. At least you'll know for sure that it has a power source that comes with it

We bought the 15 volt DC adapter from the same company. The coil worked great but no music. Their so-called "professional" troubleshooting support was worthless, all they did was tell us what's already in the instructions (make sure you have the audio cable plugged in all the way). Their instructions say to use a 15-24 volt DC adapter so I bought a 24-volt adapter from another store and that did the trick. Coil and audio work great now. I hope this is helpful to others who encounter this same issue.

Built in about 10 minutes. I am an electric engineer, but this was great fun to build. It had no trouble lighting up a fluorescent bulb, black light tube, various neon bulbs. That's probably the coolest thing this can do. The brightness peaked at ~20 volts on my dc bench supply. While this is definitely for beginners, it does require knowledge to get it working and it's a fun project for all skill levels because it's $10. The music feature was pretty useless although it does work to demonstrate amplitude modulation, you can hear it clearly. The spark it emits is tiny but definitely visible. Again, coolest thing it does is light up bulbs.Some tips:- You need a DC bench supply with DC plug, or maybe two 9 volt batteries in series soldered to a switch and then to the board. Without a bench supply you'll need to get creative.- Use a lighter to burn the ends of the copper coil. But do not do so with the top of the lighter flame or the wire will melt. Run the wire close to where the fire is emitting from the lighter and run it 1-2 times through until it stops smoking.

It went together okay. Everything is clearly marked. The instructions say to keep the coil of wire .5 cm from coil. I made a coil spacer to enforce this after the wire got too close to the coil and started arcing. Didn't work. Made a new coil spacer at .5mm and got another wrap of the black wire and it worked just fine.Unit uses a fair amount of power. I had to break out my bench power supply to have enough current. Last night the end of the coil wire was striking an arc into the air but today I have to bring metal near it. It likely is a function of humidity. Last night got down to -10°F so it is dry.The coil has wire that is about 0.0055", easy to break, be careful.I haven't tried the music part yet. I'm not plugging it into my computers sound card, I look for some old computer speakers and try that and update.

I am an Electronics Assembler and I have built other musical tesla coils like this one and this has to be the worst clone I have ever seen.The unit was fun to build and looks nice, but the audio rises and cuts out badly. I tried a couple different things, but I think the issue lies with how the secondary coil is wound or the blue LED having a higher voltage drop than the red LEDs on my other units.I rebuild the primary wiring numerous times in an attempt to account for these issues, but I could only slightly improve audio quality.The music side of this doesn't work enough to play music. I bought a similar kit from a different vendor and the music was crystal clear.Good instructions. Looks nice.If you want a tesla coil that is easy to build and almost plays "music", this is for you. If you want one that works for music as well, go with the original PLL TC.

The coil works but is a bit underwhelming but still super cool! Thank you!
