DIY 18650 Lithium Powered Tablet/Computer

A DIY 18650 powered tablet/computer built using an Odroid XU3 Lite single board computer and Odroid VU touch screen.

This uses the same computing and touch screen hardware as the previous prototype but upgraded to lighter 18650 batteries instead of a heavy SLA battery, and a lighter plastic case instead of a heavy timber one.

Minimal Tablet Mode

Desktop Mode with keyboard, mouse, speaker, and supplemental power
