For Lego World 2014 I was asked to demonstrate the new Sbrick. So I converted my new Link Belt PF-excavator into the Sbrick-version. Now it can be operated through a smartphone, or an iPod (as in my case). It also allows to controll the speed of the motors, giving very precise controll over the digging functions.

I’ve compiled a small video. Filming was done by Mahjqa at Lego World 2014.
