Japanese fog-stick teardown.

This is purely a technical video and not promoting the product.

I saw this device for sale at a local shop and bought one to check out. It turns out to be a product of one of the "big players" in the industry. Their history is interesting in its own right if you search for J T International and look at the Wikipedia entry.

As a result of its pedigree the construction is very refined. The circuitry is logical and minimalist, but a cut above more basic devices. I'd guess from the price that this is a loss leader, with the real earnings coming from the associated cartridges.

The magnetic interlocks and extremely good quality contacts actually make this a rather pleasing device.

Although most users will opt to use the disposable cartridges, the option is there for the technically inclined to reuse them if desired by drilling a small hole in the case and sealing it with a bit of tape.

In summary. Like others associated with prominent industry leaders, this unit is very good quality, with a little touch more flair than usual.

This one took a while to reverse engineer. Not because of its complexity, but the size. It was very tricky to probe both sides of such a tiny PCB simultaneously, even with sharp probes.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
