OpenBCI is an open-source brain computer interface that had a successful Kickstarter a couple of years ago. They are back with a $99 biodata acquisition device and a 3D-printed, brain-sensing headset. They look cool!
The OpenBCI Ganglion is a high-quality, affordable bio-sensing device. On the input side, there are 4 high-impedance differential inputs, a driven ground (DRL), a positive voltage supply (Vdd), and a negative voltage supply (Vss). The inputs can be used as individual differential inputs for measuring EMG or ECG, or they can be individually connected to a reference electrode for measuring EEG.
We are using a Simblee for our on-board microcontroller and wireless connection. Simblee is RF Digital’s next generation Arduino-compatible radio module. It is smaller, cheaper, and more robust than the RFDuino, which we have been using on our OpenBCI 32bit Boards and USB Dongles. The new Simblee provides user programmable flash, 29 GPIO pins, and the ability to update software over the air (OTA). Every Ganglion will be pre-programmed with versatile firmware so you can get started sensing your body right out of the box. We will also break-out up to 20 of the GPIOs for you to hack with.
Teller, the silent half of the Penn & Teller magic act, explains seven cognitive biases that magicians exploit in order to “alter the perceptions” of their audiences and achieve impossible-seeming feats.
Philosophy and Predictive Processing is a new online research compendium in which neuroscientists, psychiatrists, philosophers-of-mind, and other big thinkers explore the theory that we’re always hallucinating. Our brains aren’t just processing information from your senses so we can perceive reality, the authors argue, but also constantly predicting what we’ll encounter, presenting that to us as […]
Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
