Worked on the design of a minimal LEGO Technic finger, version 1.0, using a flexor tendon to bend the finger and an extensor tendon to straighten it. Along the way, I learned I had to prevent hyperextension to keep the joints stable. Designs I’ve found online seem over-engineered and contain too many parts: after all, it’s a model. Now I need to build a refined version with an eye toward eventual automation.

Starting my journey on a road paved with virtual gold
My low energy nudges me toward an equally low-energy task: learning enough about crypto to answer the question, “What is crypto?” Forbes classifies 67% of crypto investors as high confidence, low literacy; it seems they’re attracted by a belief wealth can be safely created out of thin air. Like them, I cannot even explain its basic terms, so today, I opened a Kraken account and transferred $100 to kick off my research, triggering a fraud alert from my bank questioning this “suspicious activity.”
Hubs, liftarms, clutches, and patience
Planned my next LEGO Technic adventure. Ordered components, including 100 grey hubs, 60 black modified triangle liftarms, and 8 white geared clutches. Even with a substantial collection, a single project can easily demand dozens of the same piece: there’s always something missing.
Child’s play
It took all five adults, two wedges, and a rubber mallet to remove one panel so other panels could be slotted in to complete this Little Tikes slide. The little tike was happy, though.
Start ’em young
I’m now in Newcastle upon Tyne, my hometown. Much of the city center is still recognizable from my childhood, just more spiffed up. At Fenwick department store’s toy department I picked up a DUPLO set for the almost two-year-old grandchild of the friends I’m staying with.
LEGO model of AKL at AKL
Now at Auckland Airport where I made a point of stopping by this LEGO model of Auckland Airport. Completed this year to mark the airport’s 60th anniversary, it showcases the original 1966 airport (not shown here) alongside this 2029 vision, when a new domestic terminal will be integrated with the international terminal.
White spaces
The world gradually turned white as snow fell all day. Indoor activities won out, including this jigsaw puzzle featuring the art of Keith Haring. Once we’ve assembled all of Haring’s instantly recognizable symbols, the white space between the symbols will be a bigger challenge.
LEGO welfare check
Dwight had minor hand surgery this morning (carpal tunnel release). Some time after he disappeared into the den this afternoon, I decided I’d better do a welfare check. Despite the surgery, it turns out he’d been busy staging this LEGO Christmas village.
LEGO machine to align plates stud-side up
Lined up recently introduced large LEGO worm gears as a conveyer for 1×1 plates, much like an Archimedes (water) screw. An unexpected bonus was that the plates were consistently flipped stud-side up. This replaces all my work in recent weeks on pneumatic devices to flip 1×1 plates. Click through for a short video I made today.
A LEGO plate flipper
Successfully prototyped a machine, shown here, that accepts a LEGO 1×1 plate, regardless of whether it’s stud-side up or stud-side down, and spits it back out stud-side up. (Motorized pneumatic valves, an air compressor, and a computer are off-camera.) This afternoon I worked on my next challenge: a feeding mechanism to supply this machine from a queue of randomly oriented plates.
