New technology can change the way we receive news and entertainment, though. Radio challenged newspapers in the early 1900s, and television challenged radio. Now, it looks as though traditional television has its own competitor, but it’s not one that’s easily separated from television. It even has television in its name — it’s what we’re now […]

Most of the basic components for this network are already in place to allow the development of tele-immersion. Tele-immersion is the scientific community’s answer to the holodeck. ­By combining cameras and Internet telephony, videoconferencing has allowed the real-time exchange of more information than ever without physically bringing each person into one central room. Tele-immersion takes […]

The Easy Pulse sensor is designed for hobby and educational applications to illustrate the principle of photoplethysmography (PPG) as a non-invasive optical technique for detecting cardio-vascular pulse wave from a fingertip. It uses an infrared light source to illuminate the finger on one side, and a photodetector placed on the other side measures the small variations […]

There are many different kinds of fabric displays. Some use a still image as a starting point, relying on fabric with special properties to make the design more eye-catching. Other fabric displays can show full video with sound. Each method relies on different technologies, and all have their advantages and disadvantages. A few fabric display […]

A new PCB design web application was released this last week called PCBWeb. The website states that PCBWeb is a free browser-based CAD application for designing and manufacturing electronics hardware.  The tool is currently released in BETA and allows you to create a schematic, full circuit board layout, and then export to gerber format for […]

Video game developers constantly strive to make their games more realistic, both in terms of visuals and (perhaps most importantly) game-player interaction. Players want to be ab­le to do more in their virtual worlds. While in the past this has led to more complicated joystick controllers that look like they’d take a week to master, […]

IDK started out as a discussion one night at a makerspace with the idea of adding some sensory interaction to a video game beyond the usual accelerometer or motion capture input. What ended up evolving from that discussion over the past year is a simple easy to use kit that allows software developers and creative thinkers […]

Google executives claimed that the company wasn’t interested in building hardware. But some Web journalists and bloggers remained unconvinced. By early 2008, it became clear that the Google executives had been straightforward all along — Google wasn’t getting into the handset hardware game. But they were getting into the handset software business with a mobile […]

For the last year I’ve been working on a prototype for a Solar Inverter that can be Grid Intertied. A solar inverter takes the 12V DC (or other voltages) from the solar panels and converts it to 120V AC which is the power that most of your household appliances use. A Grid-Intertied inverter allows you […]
