Building a brighter tomorrow with LEGO® bricks

Building instructions and buying my models

A while back I posted that I was considering how best to share building instructions for my creations. There were several comments on that post and also a few email exchanges I had with people over this topic, and I’ve also had a chance to discuss it in person with a few people at BrickCon in Seattle this past October. And what I’ve decided on is this:

Glacier National Park Bus

Glacier National Park is famous for its iconic old-fashioned tour buses with ten doors and an open roof. I’ve never been to the park, but I built the bus for BayLUG’s "National Parks" theme building contest at the September 2010 meeting, and displayed it at BrickCon 2010 in Seattle. I’ve made a few minor adjustments since then, but the original build was done in only two hours.

Seven-way radial symmetry technique

I just stumbled across a way to build a 7-way radial symmetry in LEGO.

A technique for building 7-way radial symmetry in LEGO. The blue 2×2 plates are connected to each other using plate hinges in a ring, and when I built that I noticed the ring looked like the right diameter to go around a 4×4 round piece. The hinges actually protrude a little into the center, but by sandwiching the two 4×4 rounds together and filling the space inside with a round 2×2 plate and seven (leaving one stud open) 1×1 round plates, you can make it all fit nicely. And since the 4×4 rounds and 2×2 round plate have axle holes, it can easily be connected to any Technic mechanism.

If you stick an axle in the middle it twirls like a top – it’s very well balanced.

Maker Faire 2010

Here are the pictures from the Bay Area LEGO Users Group & Train Club‘s exhibit at Maker Faire 2010 Bay Area in San Mateo, CA.
We had a 40′ by 50′ space just like last year, but this time we set aside about half of it as a play area for the little ones. We dumped out loose LEGO parts on the floor (including a DUPLO area for the really little ones) and spread them out on some tables as well, so that fairegoers could build whatever they wanted. We then had some tables set aside to display these MOCs (My Own Creations), and had volunteers who would take pictures of the models and put them up on a computer. I brought my video projector and we had a continuous slideshow running all weekend with pictures of these MOCs.
