Rated 5 out of 5 stars.
Tiny Tesla, big sparks.
This BD243 mini coil runs on 9-12V and is fully assembled—no soldering, no tuning.
Just hook up power and watch it throw wireless arcs.
Board size is about 3.1x4cm, perfect for desktop experiments or science demos.
Unbranded, made in China, but it works.
One piece.
If you ever wanted to learn about resonant inductive coupling or just annoy your roommates with tiny lightning, this is your excuse.
