Hack a Day
[Max Ogden] wanted the option to add sensors to his Parrot AR Drone. This a commercially available quadcopter which runs Linux. This makes it rather easy for him to use Node.js to read the sensors from an Arduino board. The use of the Arduino is merely for easy prototyping. It is only needed to bridge the drone’s [...]

[André Sarmento] needed to connect a computer to an RS-485 bus. A simple converter can be sourced online, but the only thing he could find locally that was even close was a USB to RS-232 converter. He used that component to craft his own USB to RS-485 bridge. RS-485 is often used for remote sensors [...]

Hack a Day
There are few things more frustrating than being in the middle of working on a project and realizing that you are missing some crucial component that ties the whole thing together. According to Murphy’s Law, this sort of thing will only happen when parts are completely impossible to procure. If you’re ever hunting for a [...]

This is the 2nd and final part of this project. If you haven’t seen part 1 yet, jump back and check it out. Now that we have the controller box made and ready to go, we just have to build some simple stomp sensors. As I said before, I doubt this will hold anyones attention [...]

Hack a Day
While his wife was out-of-town [James] jumped at the opportunity to do some snooping around with her Chevy Tahoe’s parking assist sensors. We can understand how pulling parts out of someone’s car would make them none too happy. But we find it hilarious that it’s a leased company car he’s tinkering around with. But we’re [...]

Hack a Day
[Bill Porter] is helping a friend out by designing a simple security system for her home. It relies on Xbee modules to alert a base station when doors are opened, or a pressure mat is stepped on. The door sensors are quite simple, and you’re probably already familiar with them. One part mounts to the [...]

Hack a Day
The Nike+ hardware is obviously an interesting device. We haven’t heard a whole lot about hacking one until now, but [Dimitry] has decided to change that. Many would assume that the data transmitted off of these sensors is quite simple, however there’s a bit more than meets the eye. Amongst other challenges, all the data [...]

Hack a Day
[Jackzylkin] has posted an instructible showing, in detail, the process of creating a USB typewriter. He takes us through the process of disassembling the typewriter, mounting all the sensors where the little hammers strike, and wiring it all up to a custom board to interface with the computer via USB. While he is selling the [...]

This is Precious. Precious is a bike that the folks over at BreakfastNY have anthropomorphised for a good cause. By adding sensors for a variety of data sources to the bike, and transmitting them back to a server via a cellular module, Precious can spit out cheeky comments about the ride on its Twitter feed. [...]

Hack a Day
[Stewart Allen] acquired a Mindstorm kit about a month ago and he’s already building his own sensors for it. He wanted a more accurate range finder with a narrower measurement field than the stock sensor. Mindstorm has the option to communicate with sensors via an I2C bus. [Stewart] set up an ATtiny45 to act as [...]
