RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Did you wish when you were a kid that
you could get paid for building stuff out of LEGO blocks? It probably never occurred
to me at the time (not much did), but obviously it occurred to the people at
While a lot of artists create their LEGO sculptures out of a sense of artistry[sic]
je ne sais quoi, for these folks it's serious business. Bright Bricks has paying
customers who use the talent of the team to design and build promotional props.
In this case, Rolls-Royce contracted with them to prepare a half-size scale model
of their new Trent 1000 gas turbine jet engine, which is destined for Boeing's 787
Dreamliner. According to
Gizmodo, it took 152,455 LEGO bricks to build the 677-pounds,
6.5-foot-long model. Time from start to finish was an incredible eight weeks by
four people - pretty amazing! "It required the builders to go through the actual
CAD plans of the engine to reproduce every component accurately with Lego pieces."
No doubt critical detail was omitted from the plans.
No cost info could be found, but the cost of the LEGO blocks alone was probably
pretty high. LEGO donates material for some non-profit projects, but I'm guessing
for commercial ventures like this that they have to buy everything - albeit probably
at a good bulk price since it is good free advertising for LEGO.
The video below is a time-lapse compilation of the team building the
engine. You can see the computer sitting there with the construction details on
it. These images are captured from the videos.
