LEGO’s excellent Power Functions components have brought a new ease to motorising Technic models. Small, simple to install and reasonably powerful, the wide range of motors, infrared receivers and battery boxes have found their way into countless Lego creations featured here over the years.
It didn’t take long however, for the clever boffins in the Lego Community to think ‘Great… but what if Power Functions was really powerful?…’
The result is the BuWizz brick, an integrated rechargeable battery and bluetooth receiver that delivers up to eight times the power of LEGO’s own Power Functions system. To which Anto of Eurobricks thought ‘Great… but what if I had two…’
This is the fruit of Anto’s endeavour; a neat if unspectacular looking Technic excavator, with two BuWizz third-party bricks. The first controls the independently driven tracks (each powered by a Medium motor), the front-mounted blade (also powered a Medium motor) and the arm-mounted LEDs.
The second BuWizz device controls the superstructure rotation (via a Large motor), the two-stage arm (via an XL motor and Large motor respectively), and finally the bucket (powered by a Medium motor).
That’s a lot of motors and, thanks to those two BuWizz bricks, a lot of power too. So much so that Anto’s Technic excavator really can, well… excavate. Full details can be found at the Eurobricks discussion forum, and you watch Anto’s excavator in action via the video below.
