Notes.
First, some changes to my section headings to be a bit more descriptive. And second, I'm adding a "Credits" section for attributing people who send me links. As always: If you read something good, send it over.
Oh! And I'll be at RAPID (the big 3D printing conference) this week, and am giving a talk on Wednesday. Holler if you'll be there; I'd love to meet in person.
Wayfinding & Strategy.
- Kickstarter's PBC status is pretty rad.
- Andy Dunn on Digitally Native Vertical Brands.
- Motivate, the biggest bike share company in the US, is now contracting frame manufacturing to a company in Detroit.
- The MTA released (harmless) perfluorocarbon tracer gases in a few subway stations to see how they travel through the subway system.
- Marco Arment on Apple's role in the podcast ecosystem.
Building.
- Hyperloop One (formerly Hyperloop Technologies) did a bunch of shit this week, including raising a bunch of money, announcing they were using passive levitation, and testing an open sled. Start here, then explore.
- These Proxxon micro machines look pretty nice.
- How ink is made.
- Velo3D's patent.
- Panasonic has apparently created a very good weather model.
- A short but good video of Apple's "Liam" robot.
- A 1934 video of how tires are made. See also my 2014 notes from a Taiwanese bike tire factory.
- A nice quick method of finding the center of a piece of round stock.
- Photos from the Gigafactory.
Distribution & Logistics.
- A video explaining how the new expanded Panama Canal will work. Somewhat sadly, they're getting rid of the cute trains that guided ships through the locks - opting for tugboats instead.
- GM (fresh off of their acquisition of Cruise and after investing $500M in Lyft) and Lyft will test a driverless taxi service within a year.
- Claude Shannon demoing a maze solving machine in the early 50s.
Inspection & Testing.
- Eric tears down a dial test indicator - a mainstay of inspection.
- On how our nostalgia for manufacturing is really a desire for unions.
- A review of the Neato BotVac, the Roomba competitor.
- Develop3D reviews SolidThinking Inspire 2016. Their PolyNURBS feature looks *awesome.*
- Ben Wellington's analysis of the NYPD's data dump - and discovery of $1.7M in wrongly issued parking tickets - resulted in an official apology.
Stuff that doesn't fit into my dumb/arbitrary categories.
- Me, on what manufacturing is.
- I'm reading Snowball, Warren Buffett's biography.
- One of the founders of The Peachy Printer embezzled $320K from the company's Kickstarter campaign funds. The video interviews of his admission, etc., are *wild.*
- A video tour of the Svalbard Seed Vault.
- The Wikipedia page for Siemens' JT visualization file format.

Love, Spencer.
p.s. - We should be better friends. Send me a note - coffee's on me :)
