Cayenne on a Raspberry Pi

If you are building projects for IoT or the Internet of Things, a single board computer such as the Raspberry Pi, also known as the RBPi, can be a great asset. Moreover, with Cayenne installed on the RBPi, you have a drag-n-drop IoT project builder that the developers of the Cayenne software, myDevices, claims is the first in the world. Therefore, now it is easy to connect your RBPi to a mobile or online dashboard. On the other side, you have a breadboard ready to connect relays, lights, and motion Read more [...]

What are Wearable PCBs Made of?

The Internet of Things market is growing at a tremendous speed. Among them, wearables represent a sizeable portion. However, there are no standards governing the small size PCBs or Printed Circuit Boards for these wearables. The unique challenges emerging in these areas require newer board level development and manufacturing experiences. Of these, three areas demand specific attention – surface material of the boards, RF or microwave design and RF transmission lines. Surface material of the Read more [...]

Low-Power GPU for IoT

The Mali Graphical Processing Units or GPUs from ARM are popular because of their cost efficiency. ARM has optimized them to provide energy efficient, high performance graphics in the smallest possible area of silicon. As a result, not only low- to mid-range smartphones, but also tablets and DTVs are also using Mali cost efficient GPUs as ARM offers a diverse selection of scalable solutions involving both graphics-only and graphics plus GPU Compute technology. ARM offers the Mali-400MP, which Read more [...]

Devices Running on WiFi Power

Mobile devices are now radically smaller and more powerful than those available in the last decade were. They are also able to tackle more technology-related tasks compared to their erstwhile brethren. However, as their capability grows, they need to consume more power. With the Internet-of-Things and wearable technologies gaining increasing recognition from users, the need to keep them 'on' all the time is raising the topic of the best methods to power them. Imagine that you have multiple sensors Read more [...]

Raspberry Pi and the Intel Edison

The Intel Edison is an extremely small computing platform suitable for embedded electronics. Intel has packed the Edison with many technical goodies within its tiny package. That makes it a robust single board computer, powered by the Atom SoC dual-core CPU. It includes an integrated Bluetooth LE, Wi-Fi and a 70-pin connector. A huge number of shield-like blocks are available to stack on top of each other on this connector. Do not be misled by its small size, as the Edison packs a robust set of Read more [...]

Wireless sensors sans batteries

The Internet of Things has led to several simple sensors being used for applications requiring reporting of their readings wirelessly to a gateway or hub. However, most sensors require to be powered from batteries, creating logistical and cost barriers to several use cases. Now, many wireless sensor modules appearing on the market do not require batteries, as they are ultra-low power types. Several key building blocks are necessary to make up a wireless sensor module meant for IoT use. The first Read more [...]

Raspberry Pi accessories from Microstack

If you are looking for accessories for your tiny, credit card sized single board computer, the Raspberry Pi or RBPi, you now have a series of them from the distributer element14. This Microstack range of accessories allows all levels of users to create and prototype physical devices simply and quickly. Most popular among the Microstack accessories are the GPS positioning and accelerometer. Microstack claims that its modules are the “building blocks for the Internet of Things for All”. The Read more [...]

Why is Li-Fi better than Wi-Fi?

Imagine wandering through an art gallery with your PDA. As you reach an interesting canvas, your PDA starts downloading information about the painting. When you move to another, your PDA displays content relative to the current piece of art. This is called content fencing – tailoring information to specific locations so that users receive information relevant to their current location. Content fencing is impossible to achieve with Wi-Fi – radio waves have a far greater spreading power. However, Read more [...]

Connecting to the web via LEDs: Li-Fi

Connecting to the Internet is best done through copper wire or high-speed wireless connections. Not many are aware of an additional method – using light beams. This is accomplished not by the usual optical fiber stuff, but by using LEDs. Communication with lights is nothing new - it has been done before. The Scottish scientist, Sir Alexander Graham Bell had invented an arsenal of instruments for communication and these included Photophones. The first instruments to use light for communication Read more [...]

Are Biometrics Related To The Internet Of Things?

With the Internet of Things or IoT, users and developers can easily augment its functionality, since the IoT is designed to be extensible. Therefore, it is not a far-fetched expectation that the IoT is going to be all over the place and users will get all types of data from it. According to a recent study by the Biometrics Research Group, biometric sensors are being projected as the next big step in providing the necessary security for accessing that data. That is good news for the biometrics industry Read more [...]
