Double Helix Archimedes Screw LEGO GBC Module

Posted by on May 22, 2016 in LEGO | 0 comments

This LEGO Great Ball Contraption (GBC) module uses a true Double Helix Archimedes Screw to transport the balls. It uses slides (6 x 12 x 8 studs, 11267) for its screw. It works very reliably and does not jam. There are some more photos in my Flickr album.

This LEGO Great Ball Contraption (GBC) module uses Nicolas’ (Nico71) ball pump to push the balls up through the tower. The balls then roll down a rotating double helix that is made from LEGO slides (6 x 12 x 8 studs, 11267). It works very reliably and does not jam. There are some more photos over at Flickr.

LEGO compatible thrust ball bearing

LEGO compatible thrust ball bearing

To rotate an axial load LEGO developed the turn table. For light loads this works great but the friction increases dramatically with heavy loads. This thrust ball bearing uses standard LEGO balls to transform the friction into rotations. This allows the two disks to easily rotate. The balls and an additional rim keep the two disks in place.

A motor can be attached on the inside to power the rotation. Even the smallest LEGO motor is sufficient to easily rotate this 2 kg load. This thrust ball bearing is fully LEGO compatible and even allows studs to be attached to top half. Standard 14.2 mm LEGO balls can be used. The bearing measures 20 studs across and is three bricks high. This should be big enough for even the biggest crane or MOC display.

The 3D data is available from the Autodesk Gallery.

LEGO Mindstorms BB8 Balancing Robot

We have been working on balancing a robot on top of a ball, similar to what BB8 accomplishes. We used a robot balancing on top of the ball instead of inside it. This is work in progress.

LEGO Pictorial Scales for Assessing Affective Response

We have just published a nice study in which we developed and tested Emotion Rating Figurines (ERF) that allows you to assess emotional responses. The figurines are base on LEGO Minifigures. We developed a questionnaire sheet and also a physical model.

Galaxy Explorer 6000

The LEGO Galaxy Explorer is amongst one of the most popular sets of all times. In 1980 LEGO published the Idea Book 6000 that contained an alternative build for the Galaxy Explorer. The building instructions were sketchy at best. I built the Galaxy Explorer 6000 model for the Moonbase 42 at the Christchurch Brick Show 2015 and I also created an LDD file for it. The building instructions are available here. It has been great fun to re-create this spaceship from my childhood. I hope you enjoy it.
