eMBee ONE update - all working but doesn't fit

A project log for eMBee ONE Pocket Computer

A 1980s style 8-bit computer running BASIC. Includes OLED screen and a QWERTY keyboard. Oh, and the whole thing fits in an Altoids tin.

Sorry for the long pause in log entries - I actually had everything working a couple of months ago. So it now has a lipo battery connected, and can operate standalone in the tin. However, I had made the ribbon cables for the keyboard and display too long, which means they take up too much space in the tin and the lid doesn't close. Look how long they are:

What this image also shows you is my new plan for swapping everything around in the tin. So the keyboard is now in the lid, and the screen joins the main board in the main part of the tin. There are a few reasons for this, but mainly so typing is more comfortable, with a solid surface to type on rather than putting pressure on the other components every time you type something. 

As I started to chop the wires down, my soldering iron bit broke in half! Then had to wait for it to cool down before replacing it. And that's when my brain started wandering into the possibilities of designing a custom PCB, using cheaper but more powerful hardware...

Introducing the eMBee TWO!

I'm still planning to finish the eMBee ONE as a one-off piece (just a few wires to shorten so the lid closes), but if you want to build a pocket computer that boots into BASIC, then the eMBee TWO will be the project to follow.

Thank you to everyone who followed the project, and I hope to see you for the next generation of the eMBee platform!
