How To Build A Servo LED Driver

This is pretty neat, seeing as how store-bought drivers seem to run about $20!

Basic idea: strip the mechanics off of an old servo, and solder in two different resistors, so the circuit thinks the alignment is incorrect and supplies power to the circuit. Attach to a spare receiver port.

How To Build A Servo LED Driver: "One way to get into night flying is to fill a plane with LEDs. You can do that by connecting them directly to the motor battery, or to a dedicated second pack, but neither approach gives you any control. Here's how to reuse an old servo to drive your LEDs, with either on/off or variable brightness from the transmitter."

1.0 Is the Loneliest Number — Matt Mullenweg

1.0 Is the Loneliest Number — Matt Mullenweg: "Usage is like oxygen for ideas. You can never fully anticipate how an audience is going to react to something you’ve created until it’s out there. That means every moment you’re working on something without it being in the public it’s actually dying, deprived of the oxygen of the real world. It’s even worse because development doesn’t happen in a vacuum — if you have a halfway decent idea, you can be sure that there are two or three teams somewhere in the world that independently came up with it and are working on the same thing, or something you haven’t even imagined that disrupts the market you’re working in. (Think of all the podcasting companies — including Ev Williams’ Odeo — before iTunes built podcasting functionality in.)"
