A few weeks ago I got this freebie from LEGO to celebrate The Year of the Rabbit. Decided it could impersonate the Easter Bunny, so I assembled it today. It sure seemed to have more than 194 parts.

LEGO Art
Followed building instructions while marveling how Hokusai created Great Wave off Kanagawa in 1831 before the Impressionism movement had started in Europe and while Japan was still closed off from the world. The quasi-pixelated style of the over-loved print lends itself to a LEGO interpretation. Note Mount Fuji and the three boats.
Big Boy Toy
Walked the Mall of America with friends. Made an impulse purchase at the LEGO store: a reward for riding a medical rollercoaster in the past 24 hours. (It ended well, reward enough.) There’s a tradition here: whenever I visited “the doctor’s big house” (hospital) as a kid, my dad would give me a toy car.
Learning from Failure
Built then pulled apart a LEGO mechanism that didn’t pass muster as part of a larger mechanism. Time for more research, a better design, another iteration. Often, there’s more to learn from failure than success.
A Favorite Perch
I have several favorite viewpoints around the Cities. Today I cycled to my favorite railroad perch, the St. Anthony Parkway Bridge, spanning 22 tracks. There was so much activity, it started to feel unreal: I imagined myself towering over a busy model railroad.
Filling a Market Niche
Cycled past giant LEGO bricks in captivity. Inside the building, Brickmania produces military LEGO kits. The LEGO Company doesn’t produce real-world military kits as a matter of policy.

Continuously Variable LEGO Pneumatic Control
In previous LEGO robotic arm builds I’ve used servo motors to move each joint in the arm. However, the weight of the motor and related mechanism meant each arm needed to be reinforced to the point it became too bulky and exhibited excessive inertia. By contrast, pneumatic cylinders are light, and can apply significant force… Continue reading Continuously Variable LEGO Pneumatic Control
Gold Plating
Last week a friend emailed: “Release 2 [of my pneumatic machine] should have some AI to know when there’s something to load and when it’s done.” He was teasing, but I liked the challenge. Today I got the AI working. Next, I’ll add code to operate the air valve with a servo motor.
