Built this little guy for a mate of mine.
The main housing is from a speaker set designed to plug directly into a small MP3 player. The base is a machined aluminium tape head from an old-school VHS player.
As far as behaviour goes, TemPoe tries to align its solar panels with the strongest incoming light to keep its cells charged. The 2 LDR photocouples on the back allow for light tracking, while a single LDR inside the case monitors ambient light levels so TemPoe can 'sleep' if there isn't enough light available. TemPoe also monitors the output voltage of the 2 photovoltaic cells, which is used to determine whether or not to go to sleep.

Sweet. I like yur choise of materials. And I often wanted to make a "sun tracker" - for whatever reason :)
I wanted to be able to make retro 8-bit sound effects with TemPoe so I used a PIC, but if you're interested in minimalist sun-trackers you should check out some of the 'BEAM' head robots - particularly the 2DoF design which are quite impressive.
What is its function actually???

It also beeps and flashes! What more could you want?

when i fix my spindle drive   i loled

Exactly, what more do anyone need?

I will post a BEAM later. Mine doesn’t even have a beep J

I find that reading is an effective tool to gather information while staring at text.
