DIY Tesla Coil Kit - Wireless Power Transmission & Plasma Speaker with 9-12V DC Input | Electronic Welding Project for STEM Education & Science Experiments | Perfect for Home Labs, School Projects & Tech Enthusiasts

This device did not come with the instructions you have to ask the seller for them after purchase and they will email them to you. The instructions were fairly simple to follow, I did notice there were some steps missing. For now my device is not working and still troubleshooting what else is going on with it. I already found out the capacitor is not working and not sure if it it was me (excessive heat from iron) or it came like that because I only tested the resistors before soldering. The resistors appeared to be a little outside of the specs, but that is probably more manufacturer quality control rather than the person designed the kit. If you are looking for something to do then it is good kit to put together. Does not take very long to assemble but you may actually spend longer trying to figure out what is wrong than putting it together. As far as over all quality of this kit all I could really say is if you are just learning about electronics and how to troubleshoot it might be a good kit for you. The person would need to narrow down the fault, search for appropriate replacement parts, and install the replacement. Really you should not have to because instructions should be complete and everything working within specifications, but it is still good practice for future electrical engineers or hobbyists.All of the soldering joints are bad and solder goes thru the bord into the components also I think that the capacitor was broken once I solder itWent together fine, red led comes on but no spark. Double checked the components. Im not sure what is wrong, but there was no manual so I followed what the silkscreen said.I think for this review, I'll opt to the classic pros/cons format:PROS:...CONS:1. No directions, not included, not available online, not even from the manufacturer.2. Never worked, not for a second.3. Requires a 5v DC power supply, not included.4. Came in a ziplock baggie, no manufacturer warnings, not even a business card.OVERALL:Don't even waste your time...Assembly instructions were not included.please answer my request, i just need assembly instruction or diagramThe product works as long as you understand how to read silkscreens and properly place components, this is not for beginners this is for people with knowledge and constant work with electronics to build on their weekend for fun. There are no instructions, other then silkscreen, and no power supply.Cheap electronics with no instructions. I assembled it correctly and it does not work. I haven’t been bothered enough to troubleshoot it. If you really want a diy Tesla coil spend the extra money to do it right.Does not come with instructions.
