content: What is this? It has a long list of features but noplace does it mention the purpose, use, frequency, or other fundamental information about a transmitter. I can only imagine that there are people who have a specificy, probably dodgy, use for this and know what to look for.eBay auction: #195404001551

content: Looks like some scam. A single transistor with some coil connected at one end and LED, makes no sense. Don't see any power terminals either.

content: This appears to be power harvesting device deployed in the E.M radiation field of a high power transmitter. It is not a transmitter, more like a electro magnetic field parasite that produces a voltage from the near field of a transmitting antenna. The description is so poor that I cannot determine what sort of transmitter is is designed to work with.Looks like a pretty rubbish design and it would not surprise me if it does not actually work.Fraser

content: Could it be a high power induction transmitter, similar to a contactless phone charger, only more powerful?

content: It is sold everywhere apparently. You can find it on Aliexpress:https://www.aliexpress.com/i/32999201243.htmlapparently it's some kind of Tesla coil generator. The pictures suggest that there is a primary and secondary, although we don't see much. The end of what we could guess would be the secondary is open-ended. Who knows what the purpose of this is. If it does oscillate at all, then it probably makes a very nasty RF "jammer".

content: Yep, that's a pocket EMP blaster for thiefs and vandals to screw with electronics. They just put it under "transmitter" to prevent Ebay from immediately busting them. You hook up a battery and zap arcade machines, slot machines, atms, exc.
