Two models of Sega, the first generation and the second generation. The projection disc attached to the first generation of HOMESTAR is a black-and-white image effect in the northern hemisphere, with 2 pieces. The 2nd generation enhanced version of HOMESTAR PRO comes with 2 CDs with color image effects in the northern hemisphere plus 1 full moon projection CD and 3 CDs with * * *; There can be a constellation, just like a planetarium. The second generation has its own function of making meteors.
One color is a projector called Romantic Room. Pixels are not as high as Sega, and the effect is not as good as Sega. And it can only be cast on one ceiling.
2。 I don't know where it is sold in Beijing, but I know it is available in Shanghai. Just look at the sellers in Taobao who have physical stores. This thing is not copied, it is quite expensive.
