Yes. This is stuck in my head.
Okay. Someone named Paxer emulated(?) old (first in 1982) good HP15C calculator (he has also 16C & 41).
Someone posted translated repost on the habr.com, and it clicked: I want this!
Author made it exclusively in THT, but shared schematics and hex files! Amazing!
Now is my plan to do it as small as it possible; as close to the original, as possible…
Of course I started from designing “the nice HP keyboard”
I printed some keys, to test them. Clicks nice!
Then 3D design. A lot of design. Trying to do it as neat as I can.
Huh, renders looks nice. But placing everything will be really hard. Especially text! I spent too many hours, without any effect… I still have no ideas…
One more render with “opened” cover to access the battery/reset/programming…
