Have you ever asked yourself this question: “How many times can I assemble LEGO bricks before they wear out?”
Well… probably never but I did. The story would end there if I had not also the knack to build a machine to test it. Here it is:
The first version was using a metal tube attaching the top servo to the LEGO brick. It was too flimsy and died during initial testing. So I took an old CPU heat sink…
And using my trusty angle cutter, I made this new arm:
A successful test proved that the LEGO was no match for this chunk of aluminium. I then made an infra-red proximity sensor to detect if the presence of the LEGO and rigged the whole thing to an Arduino. This was shot before the test started:
and this was shot about two thirds into the testing that lasted a whopping 10 days!!!
So here are the 2 dead LEGO bricks after 10 days and 37,112 assembling and disassembling.
Don’t try this at home. It’s long, noisy and cruel to LEGO bricks.
