„The sensor on the glove is based on the SoMo by SonicWear, a wearable Arduino-compatible device that is intended for creating interactive dance and music performance. SoMo contains a 9-DOF accelerometer/gyro/magnetometer, microprocessor, battery, and XBee transmitter and receiver pair. Since it’s Arduino-compatible, it can easily be reprogrammed for custom applications.“

“ An introduction to wireless charging: changing the way we think about power
Smartphones are changing the way we live our lives, both online and off. With each new model, we are used to getting more processor speed, new features and programs, and entire new ways of using them. Despite increased capabilities, battery life simply hasn’t kept up. For most users, phones are sending out sad bleeps by lunchtime, signaling a low battery.
Wireless charging is set to change this. We want to eradicate the problem of the dead battery.“
„The Wireless Power Consortium created and maintains Qi (pronounced “chee”), the global standard for compatible wireless charging. The Qi standard guarantees that any device carrying the Qi logo will work with any charging surface that carries the Qi logo, regardless of manufacturer or brand.
Qi is backed by over 100 industry-leading companies, who support it because it allows design freedom, product differentiation, and guaranteed wireless charging interoperability .WPC also provides easy access to the essential patents.“
“ A number of definitions can be found to describe Software Defined Radio, also known as Software Radio or SDR. The Wireless Innovation Forum, working in collaboration with the Institute of Electrical and Electronic Engineers (IEEE) P1900.1 group, has worked to establish a definition of SDR that provides consistency and a clear overview of the technology and its associated benefits.
Simply put Software Defined Radio is defined as :
„Radio in which some or all of the physical layer functions are software defined“ *
A radio is any kind of device that wirelessly transmits or receives signals in the radio frequency (RF) part of the electromagnetic spectrum to facilitate the transfer of information. In today’s world, radios exist in a multitude of items such as cell phones, computers, car door openers, vehicles, and televisions.
Traditional hardware based radio devices limit cross-functionality and can only be modified through physical intervention. This results in higher production costs and minimal flexibility in supporting multiple waveform standards. By contrast, software defined radio technology provides an efficient and comparatively inexpensive solution to this problem, allowing multi-mode, multi-band and/or multi-functional wireless devices that can be enhanced using software upgrades.
SDR defines a collection of hardware and software technologies where some or all of the radio’s operating functions (also referred to as physical layer processing) are implemented through modifiable software or firmware operating on programmable processing technologies. These devices include field programmable gate arrays (FPGA), digital signal processors (DSP), general purpose processors (GPP), programmable System on Chip (SoC) or other application specific programmable processors. The use of these technologies allows new wireless features and capabilities to be added to existing radio systems without requiring new hardware.“
„ANT™ is a proven protocol and silicon solution for ultra-low power practical wireless networking applications. Designed for 2.4 GHz operation, ANT is perfectly suited for any kind of low data rate sensor network topologies in personal area networks (PANs) and practical wireless sensor networks (WSN).
ANT has been intentionally engineered to simplify practical wireless network development and optimize network efficiency. ANT-powered network nodes can operate for years on a coin cell battery compared to months for other technologies. Rich in capabilities, ANT provides reliable data communications, flexible and adaptive network operation and cross-talk immunity. “
„If you have an Arduino project where the dev board is stuck inside a machine, or attached to the rafters or is inaccessable in some other way, a wireless programming/debugging link will save you tons of time. This tutorial is an extension on Rob’s version. In this tutorial, no extra firmware or hardware (other than a capacitor) is necessary. Just use the default bootloader. I use a ‚classic‘ Arduino but of course this can be easily adapted to any version or clone.“
