Brick Show now open

This was the opening weekend for the the Brick Show in San Leandro, CA at the Bay Area Family Church, organized by Johannes van Galen and featuring BayLUG/BayLTC. The show is ongoing through July 25 so come on out and check it out!

The show features a large train layout and various other displays in all themes of LEGO. Admission is $5 each for adults (age 16+) and $3 for kids ages 3-15. Kids under 3 are free.

I took a bunch of pictures around the display today. Click on the image to see them:

Seven-way radial symmetry technique

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

7way symmetry

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.

LDraw code after the break:
