Analysis of mobile planatariums

For the mobile planetarium's projector...

The Sega Toys Homestar...

But this does a planar projection! Displays on a flat surface

and besides, the wide dome lacks appeal...

Mr. Ohira's Megastar... The Megastar-I is the one shown here.

My policy will not allow it!

Since we need to display something with high performance...

This high performance at this size...

As I thought, a handmade style here...

Using the pinhole planetarium from "Science for Adults"...

But those are just stacked up in leading bookstores!

The original version had good quality but...

The projection distance is far, and it's just a paper lantern...

Please don't talk nonsense! literal meaning: Sleep-talk when you're actually sleeping please!

A paper cup and a flashlight...

They say that "simple is best"...

But it looks decent if you line it up...

Aaa, I'm tempted to give up here...

Give up?

Ms. Yumemi's hard battle

The unbranded one is originally monochrome...

That's too much even for Ms. Jena!
