The second prototype, assembled

Nov 2, 2026hardwaremilestone

The new main board hasn't arrived yet, but almost everything around it has: a new shell, a new hinge cable, a new speaker and a new small board in the lid. I couldn't wait, so I built a second prototype around the board I already had.

Closed, opened, and the home screen. No tape this time.

What's new in this one

Getting it together

It didn't just snap together. Samples are never exact, and a few spots needed filing and sanding before the parts would close properly. But it went together in the end, and it works: both screens, the speaker, the buttons, closing the lid to save, and opening it to carry on.

Save, close the lid, open it, carry on.

What doesn't work yet

What I'm changing

Building it by hand showed me which parts are harder to assemble than they should be. The hinge spring and its little stopper are fiddly to get in, the guide around the lid board is too short, so the board can slip while the shell closes, and Start, Select and POWER sit a little too low to press comfortably. All of these are already changed in the next version of the shell.

Next: the new main board. When it arrives, it goes into this same shell.
