Review on 🎵 DIY Mini Music Tesla Coil Plasma Speaker Set - MY MIRONEY DC 15-24V 15W Loudspeaker with Wireless Transmission - DIY Kits by Rick Vidaurri

Pros: Good quality PCB with clear markings. Extremely easy to assemble. A fun shortcode with decent results for its size. Cons: No instructions. 1 screw missing. LED 2 is marked on the circuit board with the back. Contrary to what most of us are used to, the anode needs to be connected to ground, not the base of Q2. More importantly, this won't work if the primary coil isn't wound in the same direction as the secondary coil. Lots of pictures online for reference.
