10 Great Engineering Projects Using Lego

Since it’s Christmas Eve Eve, here is a little lighthearted Christmas entertainment. Regular readers of this blog or those who follow our Facebook or Twitter feeds will know that some of us are big fans of well engineered Lego projects. So, since many of us will soon be waiting our turn with the children’s or grandchildren’s Christmas Lego, we have collected together eight of the best videos of Lego engineering projects that we could find. Do you know of any more similar Lego projects? Then leave a link in the comments at the end of the post. Enjoy…

1. Lego Hello World

2. MakerLegoBot: Lego Mindstorms NXT 3D Lego Printer

Following on from the inkjet printer model above we have the next evolution – a 3D printer. What next? Self replicating Lego?

3. The Antikythera Mechanism

From the article – “The Antikythera Mechanism is what you call truly old school technology. Argued to be the world’s oldest known computer, this ancient Greek invention was used some time circa 100BC to calculate and ‘predict celestial events and eclipses with unprecedented accuracy’. Skipping past the two millennia in which it lay lost on a sea floor somewhere, the Mechanism has now been recreated by an Apple software engineer by the name of Andrew Carol, who has lovingly pieced 1,500 Lego Technic blocks together, creating 110 gears and four gearboxes in total.”

7. Working Lego V8, 32 valve engine

Designed and built from scratch this amazingly detailed model of a V8 engine took over 300 hours of work.

9. Working Lego Flat 6 Engine

The third and final engine model is a hand powered flat 6 that includes a 2-speed transmission and a limited slip differential. Brilliant!

10. James May’s Lego House

Last, but by no means least, here is Top Gear’s James May’s attempt to build a full size house out of standard Lego bricks. Sadly, the program isn’t any longer available to view from the BBC website (link below), but the video above links to part of it posted on YouTube. UK readers may already be familiar with the programme, but if you aren’t it’s well worth watching.
