Gantry Crane: Progress Update

Prototyped the x and y axes of my minimal gantry crane. Next up: z axis (hoist) and a pneumatic grabber. I’ve written a Python program to pull it all together and to interface with a PlayStation controller to help me test as I build. The final product may look nothing like this.

55-Bin System for Hobbies and Home

Started setting up a 55-bin system to organize parts for our hobbies and home maintenance, replacing dozens of plastic shoeboxes. About a quarter of the bins will hold bulk and bulky LEGO Technic parts. The bins are easily subdivided, making parts more available.

Prototyping a Gantry Crane

Finished a working prototype of the y axis of a gantry crane (the part that carries the hoist). I aimed for smooth motion, minimum parts, and maximum symmetry. Next I’ll prototype the x axis. Eventually I plan to give the completed crane enough smarts to operate autonomously.

Staring at a Bridge

Diagonal elements can be problematic in LEGO, so I’ve set myself the challenge of building a LEGO Technic model that includes a strong, minimal horizontal structure incorporating diagonal trusses. Today, on my cycle ride, I studied a 140-year-old bridge, looking for inspiration.

The Year of the Easter Bunny

The LEGO Chinese New Year rabbit I assembled a few days ago doubled as the Easter Bunny today. Here, it’s a little too close to a tray of micro-green shoots. As I was born in the Year of the Rabbit, it may reappear as itself on my birthday.

Easter Bunny Impersonator

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.
