Three of our Favorite Hackers

It’s one thing to pull off a hack, it’s another entirely to explain it so that everyone can understand.

Two Words That Don’t Mean What You Think They Do

When you hear “gravity waves” or “sprites”, you’d think you would know what is being discussed. After all, those ripples in space-time that Einstein predicted would emanate from twin, colliding, black holes were recently observed to much fanfare.

Transmitting Analog TV, Digitally

If you want to really understand a technology, and if you’re like us, you’ll need to re-build it yourself. It’s one thing to say that you understand (analog) broadcast TV by reading up on Wikipedia, or even by looking at scope traces. But when you’ve written a flow graph that…... [Continue...]

Custom Keyboard Makes the Case for Concrete

One of the worst things about your average modern keyboards is that they have a tendency to slide around on the desk. And why wouldn’t they? They’re just membrane keyboards encased in cheap, thin plastic. Good for portability, bad for actually typing once you get wherever you’re going. When [ipee9932cd]…... [Continue...]
