“HiJack” is a work in progress project from a development team at the University of Michigan whose goal is to make basic data peripherals for iDevices at very low costs. The audio jack on the devices are used to both power the peripheral and transmit data. This process of utilizing a 2 in 1 method for attaching the accessory allows for development of creative and useful attachments for the iDevices. Most of the time, the biggest cost in production of an iOS data sensor is from the right to use the “Made for iPhone/iPad/iPod” logo and the 30-pin connector. What project “HiJack” is doing is allowing development of hardware and software that don’t require the label and connector to function. According to Ars Technica, “the system uses the 22kHz audio signal, which is converted into 7.4mW of power”. In other words, has the right power for a wide array of devices as well as allowing communication of the sensor with specifically designed iOS apps.

We’re already seeing this process being used in the Square sensor, an attachment that allows an iOS device to be used as a point of sale and credit card reader. Topping off this innovation is the reports from the developing team that sensor could be built for “as little as $2.34 in significant quantities”. The project has already produced a range of products ranging from an EKG interface to a temperature/humidity measuring tool. Completely dedicated to the project and spreading it uses to the public, the team is releasing schematics and source code on Google Code and has announced their goal for porting the software to more platforms such as Android and Windows Phone 7. With such low-costs and ease of finding step-by-step coding, what kind of user made attachments can we expect to see? Let us know your thoughts in the comments below. Check out this home made peripheral that’s already creating some buzz.
