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.
A small (51 men aged 24 +/- 3 years) study published in Neuron tasked experimental subjects with practicing the ancient Greek mnemonic technique of “memory palaces” and then scanned their brains with functional magnetic resonance imaging, comparing the scans to scans from competitive “memory athletes” and also measuring their performance on memorization tasks.
University of Western Ontario researchers examined the electrical activity in several patients before and after their life support was turned off and they were declared clinically dead, when the heart had stopped beating. In one patient, brain waves, in the form of single delta wave bursts, continued for minutes after death. “It is difficult to […]
Can you “hear” motion or light flashes? If so, according to new research from City University London, you may be experiencing a not-so-rare form of synaesthesia. Synesthesia is the fascinating neurological phenomenon whereby stimulation of one sense involuntarily triggers another sensory pathway. For example, a synesthete might taste sounds or hear colors. (In this study, […]
What could be more fun than a slingshot that shoots tiny airplanes? A slingshot that shoots tiny glowing airplanes of course! These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
