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

An easy build with one critical part- soldering the tiny hair thin coil wire to the board. Be sure to carefully scrape off the coating on the wire before soldering and don't fry/break the wire while doing so. This is the third Tesla coil kit I've built- they all work. The other two kits from other sources. I use an old 16 Volt power source with a round plug that fits perfectly. On this kit I don't get the tiny spark at the exposed wire at the top but if I hold something metal close to it you will see the spark. Be careful, the cooling fins may get very hot, don't leave it on too long. I had some thermal paste from other projects and I added some between the transistors and the heat sinks for better heat transfer. The red LED is Power but it doesn't say what the blue LED is for. The 2 pin header in Step 5- for an optional fan for cooling but no other info on this- what kind of fan? Would fan voltage be determined my your input voltage or is it a set output voltage? I'd like to install one and show you how it looks/functions. I tested the 2 contacts with a multimeter while the unit was operation with my 16 volt power source. Got no reading from the 2 "fan" pins. ???? Looked on the other side of the board and it appears (I think) that only one pin is routed to something. **UPDATE: I purchased a tiny 24volt 2 pin fan and connected it to the fan contacts and used a 24 volt power source to the coil and the fan works! Now have to rig up a holder for the fan.

Enjoyed making it

Pas de cable audio, pas de ruban double face, pas de connecteur a 2 broches, pas d'instruction en anglais ou francais. Le PCB n'est pas le même que celui montré sur la photo. En plus après 5 a 10 minutes d'usage un des transistor a brûler malgre que le dissipateur thermique était bien installé. Bref perte de temps et d'argent a cause d'une description mensongère de l'article.

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.

Missing few pieces, instructions NOT in English. No help anywhere on how to do it. Avoid at all cost.
