Well I think it’s just because they used official Nintendo logos, so the listings on AliExpress probably got taken down (maybe only in Europe?).

But the company still exists and you can get their stuff on other shops. But you’ll have to do some research I guess. I found this German shop that still has some.

I added an OLED display to both my GBC and DMG, and I’m very happy with it. I wrote about in on my blog :)

I’m also using a humidity sensor in my custom bathroom setup. It really detects the start of a shower quite fast. 10s to 30s I’d say, depending on the humidity before starting the shower.

But also I have a very small window-less bathroom, so you mileage may vary.
