Why do older bricks have greater clutch power?

I have some pre-2000 (rough date to split the collection to old/new) System and Technic sets that are from different sources: some are from my childhood, while others have been acquired in "used" as well as "new" condition. They share a common…

Are there two versions of the set 6205?

I own the LEGO set 6205 and I noticed from another picture on Brickowl and Bricklink the wing design is different. Is there an alternate version or did someone who had the set mix up the pieces and build it the wrong way?

NXT brick output ports not working properly

My NXT brick will not let motors run. When I download a program the motor will move forward and backward and then stop - sort of a wiggle. Another motor will not work at all. This happens for all three ports. Any suggestions.

Why does LEGO avoid 2x4 plates on these occasions?

As this year's LEGO city advent calendar gradually gets opened, I have repeatedly been astonished by the choice of parts: At least twice so far (in the oven and in the catapult target), two 2x2 plates of the same colour had to be placed right next…

Older compatible/clone brand with PB initials

I have quite a few bricks from a LEGO-compatible brand and would like to know more about the brand these are from. I have them since the very early 90s, if not earlier, so I would think they are a leftover of either a GDR brand or any other former…

DUPLO Train Action Bricks

I have the weirdest thing with my son's set. Currently one of the yellow action tiles honks the horn but the other yellow brick does not. No matter the lighting conditions, the position, orientation, etc. They both used to work and suddenly one is…

What sites are available to sell original boxes?

A couple of years ago, I stumbled across a site (not Ebay) where LEGO fans buy and sell items. I have some large boxes for various sets to sell. All my son's LEGO collection is in plastic boxes, and I don't think he has any interest in keeping the…
