The Martin Howard Typewriter Collection has a new treasure to show off: a Munson typewriter, with horizontal rods that control a hammer that strikes the page from behind:
The Munson typewriter is a remarkable piece of engineering, with a complex and original mechanical design packed into a small frame. Its inner workings are largely exposed, so the machine comes to life with moving rods and levers when being used.
The Munson does not have type-bars but uses a horizontal type-cylinder (about the size of ones finger) that slides from side-to-side and rotates to have the correct character move into place. Then a hammer strikes the paper from behind, pushing the paper against the ribbon and type-cylinder. Type-cylinders with different fonts were available.
With two shift keys, uppercase and figures, only three rows of keys are required.
The Munson was introduced in 1890 and did quite well on the market; however, today it is hard to find. The Munson became the Chicago in 1898 when the enterprise was bought and the typewriters were manufactured by The Chicago Writing Machine Co.
Zero-knowledge proofs are one of the most important concepts in cryptography: they’re a way to “validate a computation on private data by allowing a prover to generate a cryptographic proof that asserts to the correctness of the computed output” — in other words, a way to prove that something is true without learning the details.
Retroworks’ $18 decoder rings don’t have much by way of cryptographic robustness (they compare disfavorably to the cipher-wheel wedding rings my wife and I wear!), but they’re not a bad way to introduce the littlies in your life to the idea of habitual secrecy. (via Red Ferret)
This week (and next due to the nature of different release dates for the direct market and the book market) marks the release of the first collection of SHADE THE CHANGING GIRL v.1: Earth Girl Made Easy, which compiles issues 1-6 (previously). It’s a heavy load to recreate a character that giants before you have written. Steve Ditko is a master of the strange. His mind a merry-go-round of experimentation.
The Fader Stealth Quadcopter from TRNDlabs packs incredible flight performance into a package small enough to land on your phone screen, and it’s available now in the Boing Boing Store.The Fader’s six-axis gyroscope module gives it perfect balance in the air. This makes the onboard 720p HD camera all the better for shooting amazing flight […]
Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
The PiCar-V learning kit comes with everything you need to build a Python-powered robot, and it’s currently being offered in the Boing Boing Store.
