With the popularity of gesture controlled devices like the Nintendo Wii, Microsoft Kinect, and Playstation Move showing no signs of slowing down, it’s clear that individuals playing games want to be more physically involved and interact in ways like never before. This increase in physical activity has helped to break the stigma of some games turning us into “couch potatoes,” but is there more of a therapeutic benefit to this type of interaction? I believe there is.
Infrared Pulse Sensor is the latest addition to our beginner-friendly series of Weekend Projects. Inspired by a photoresistor pulse sensor, MAKE’s Technical Editor Sean Michael Ragan built this IR-based pulse sensor using emitter and detector diodes, combined with an LM384 op-amp IC and an Arduino.
Are we entering an age where those technologies, formerly found only in the imaginations of science fiction authors, now become possible for anyone to attempt? What can we do? How far should we go? These are questions we’re only beginning to explore.
World Maker Faire in New York will be offering a robust assortment of DIY Bio presentations an exhibits, with everything from circuits created from slime-molds to hacking a brain’s EEG signals.
What is being billed as the world’s first (and most expensive) cultured hamburger patty debuted in London today, NPR reports. And the project’s anonymous funder was unveiled, too. It’s Google’s Sergei Brin.
This is video from a Parkinson’s patient who underwent Deep Brain Stimulation (DBS), a treatment that uses electricity to control the brain. Essentially, they implant electrodes in a specific region of the brain and the electrodes are tied to a pacemaker placed near the patient’s heart. He can turn on and off the stimulation, and control the amount of electricity that gets to the brain.
Take those MRI slices and stack them back together to build your brain.
