Love this August, 1935 article from Science and Mechanics magazine about the hulking, three-ton ballistic computers -- reminds me a lot of the way that Asimov and Heinlein both wrote about "big brains" in their fiction over the next couple decades:
The "fire, control" machines, now used to plot the flight of shells from modern guns in moving ships, against moving targets, deal with practical conditions like this; and the machine pictured could answer a question of this nature, as well as a good many others less specialized. For instance, three or more heavenly bodies (like Earth, Sun, and Moon) are moving in their orbits at different rates of speed and varying distances, attracting each other. What will be the combined result of their forces, in changing the positions of each, in a given period? It is an enormously difficult proposition for the best mathematician in the world. With this machine, its ten "integrators" would be adjusted (by setting dials) to represent the varying factors of the problem, and then started turning. The friction discs and gears of the machine would operate on each other, each of them with an effect proportioned to the energy and speed it represented; and, on the final chart at the "answer table" of the machine (see illustration) a curve would be drawn by a metal pen, representing the formula desired (not necessarily a physical picture of the motion of one of the heavenly bodies, but a mathematical picture of it).
SOG’s $60 Sync II “wearable belt buckle” multitool isn’t the only multitool/buckle on the market, but it does add a couple very sensible innovations, like a clip-on/clip-off base that lets you use your tool without taking off your belt, and a squared-off form factor (like a pair of folding travel sewing scissors) that adapts the […]

The mechanical Royal Kludge keyboard (Update: in stock here) seems to do well with Amazon reviewers, but there are no guarantees you’ll receive one with the coveted OFF/NO switch.
While some people still maintain that everything in Apple’s walled garden “just works” and is immune to the rampant malware of the Windows world, the reality is different. The Mac’s growing market share has made it a much more viable target for malicious actors, and its built-in tools aren’t always enough to fix things. Drive […]
Boasting an IPX6 waterproof rating, the Trakk Bullet Ultra Compact Waterproof Bluetooth Speaker resists dust and heavy rainfall. It’s currently available in the Boing Boing Store.The Trakk Bullet offers the same wireless convenience as other portable speakers, but few are built as tough as this one. Its utilitarian construction is designed to be a totally low-maintenance […]
The Ticwatch 2 Active Smartwatch is a simpler take on an active wearable that raised over $2m dollars on Kickstarter and is currently offered in the Boing Boing Store.Somewhere in between the single-day battery life and platform-specificity of the Apple Watch and Android Wear devices, there exists the Ticwatch. Instead of trying to shoehorn another […]
