James May built a full-sized LEGO house for his TV show James May's Toy Stories on the BBC back in 2009 using around 3,500,000 bricks. Whether you'd actually want to do this yourself...
During the episode they spent some time with engineering students working out the most load bearing configurations of bricks especially for the upper floor, as well as ...
Here is a study that demonstrates one way to use LEGO in ADHD counseling.
If you are looking for a more rigorous outcomes-focused methodology, there's another study that looked at the impact of LEGO on social skills development in children. It found significant improvement compared to the control in a pre-test, post-test study.
If your interested in ...
I asked Gary Istok on your behalf in this Brickset Forum thread, who is an expert on LEGO's history. He said the following:
When LEGO replaced the Cellulose Acetate bricks circa 1963 with ABS
plastic for non-trans parts, and polycarbonate for the trans ones,
they had a problem with the red and yellow parts. For some reason
(I'm not a chemical ...
The vast majority of lego related injuries included some variation of the following:
Cutting fingers by trying to disassemble Lego
Stepping on Lego (of course)
Quick movement of the corner of a piece against the skin, scratching or cutting the skin
Swallowing and/or choking on pieces (mostly young children, very young)
Getting pieces stuck in orifices such ...
I can't comment on why Lego stopped selling Primo. But I can assure you that Duplo is fine for children. The smallest pieces are way too large to choke on, as far as I can tell. Small babies probably don't know how to put the pieces together very well, but that doesn't stop you from building a little house or car or something and letting them play with it.
There is a list of recalls dating back to 2002 on the LEGO site, so that's a start.
It contains two items:
A specific version of the IR remote, typically used for trains.
A one piece toy truck, only sold in the USA.
Hello Eran's family! How are you all doing today?

pull up one of your official LEGO mini movies and click on the

Here's an idea for a stop switch using a remote control and one's wrist.
Place your wrist on the switch to start the motor. With your hands free you're still able to carefully adjust your running gears. But what if something (or someone...) gets stuck?
Just lift your wrist and the motor will stop immediately. No need to quickly flick that switch on the ...
No, the LEGO Mindstorms EV3 is NOT waterproof. Any electronic product that is capable of being immersed in water will clearly state in the packaging/manual the level of water protection provided. This may be in the form of an IP Code:
Ingress Protection Marking, classifies and rates the degree of
protection provided against the intrusion (including body ...
If your geartrain contains z24 gear you can substitute it with z24 clutch gear. It has built-in safety mechanism - it would slip under certain toque and as result of this it will stop transfering motion if gears placed after it would stop or get blocked.
At about 9 years old I fell out of bed onto a constructed set. Managed to get into my parents bed and fall asleep. In the morning the pillow was soaked with blood and I got the day off school. As far as I am aware there were no lasting side effects, but ay bleeding to the head is not considered healthy.
Even in early 1980s there were some patches having Cadmium. I should link to the study but lost it now.
Here is somewhat proper reference:
Eating is something to avoid. Hand-to-mouth (hand skin licked) behaviour is not as fatal.
Yes heat is the ultimate problem but the most likely failure will be from the commutator brushes.
As the voltage is increased so does the heat of the sparks created as the brushes pass from one commutator segment to the other. This is a particular problem on a 3 segment commutator.
At 30V even if the motors can stand the mechanical loads and heat generated I ...
