Some modifications brought to this R2D2 kit, to add features and take advantage of the hardware for potential future improvement. I'm not showing how I changed things but only what I changed, also I'm talking too much there, so you might want to speed up the playback…<br /><br />Modifications include:<br />- rework of hinges on middle left flap door<br />- red laser pointer integrated in left arm<br />- power supply barrel jack position<br />- power switch position<br />- speaker position<br />- USB OTG extension<br />- mSD card slot extension<br />- USB plug<br />- UART port (giving access the shell, by default under Android, or linux if booting with a prepared mSD card)<br />- magnetic locking for the back cover
