Wired's Quinn Norton has a great feature in today about amateur clock-hackers who build their own super-accurate atomic clocks. These "Time Nuts" pull stunts like taking their kids hiking in the mountains for a couple days, using their cesium clocks to recreate Einstein's time-gravity experiment to prove that the family had gained 22 nanoseconds on their neighbors by rising high above Earth's gravatic center.
This is just part one -- more tomorrow!
With the end of the Cold War, and with telecommunications technology advancing rapidly, surplus stores and eBay have filled up with discarded precision time equipment once beyond the reach of all but governments. Cesium clocks, rubidium clocks and even the occasional hydrogen maser can be had for less than a decent laptop. A recent search on eBay turned up an HP 5061B cesium standard for sale for $2,000, and you can get a telecom surplus rubidium standard for less than $400. Some of this equipment costs upwards of $50,000 new.
Their access to once-forbidden technology lets the time hackers play in a realm of precision that underpins the modern technological world. A select few, like Van Baak, have started exploring the underpinnings of the universe.
CutiePi is a tablet based on the Raspberry Pi: compact enough, but more open, versatile and hacker-friendly than mainstream models from Apple, Microsoft or the Google coprosperity sphere. CutiePi is a complete Raspberry Pi in a tablet form factor, minus the trouble of connecting monitor or power supply. It’s slimmer because of using Compute Module, […]
I am addicted to Thinkpads in large part because of the trackpoint (AKA "The Nipple") -- the little wiggly joystickbetween the G, H and B keys that allows me to control fine mouse-movements without bending my hand into the RSI-inducing trackpad position; between that and the amazing, best-in-class warranties, I am a committed Thinkpad user, […]
You can buy microcontrollers for as little as 3 cents, if you order a lot of them, a staggeringly cheap number even if you’re so young you don’t know a Zilog Z80 was $10 in 1978 money. But are these cheapo parts any good? Hackaday says they’re terrible, but Tim finds a role. [it] surely […]
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]
Want to make a hit? The right software is out there for anyone, but any music producer will tell you that finding the right sound can still take time and talent. Still, the right tools are a great shortcut, which makes this Synth & Sound Pack Bundle absolutely priceless. And now that it’s on sale […]
