Rotary encoders and Arduino combine for awesome universal remote

In his latest hack, “Matlek” has come up with an entirely new take on the universal remote, using a pair of rotary encoders instead of an array of buttons to output up to 400 individual signals.

One 20-step encoder in his remote selects the device to be controlled, while the other picks the function, like changing the volume or channel.

Pressing down on a built-in button on the action selection encoder executes a command, while if it’s held down for long enough, it can be programmed via an IR receiver. An Arduino is used to control the gadget because of its small size, and the project expands on several helpful concepts like SD card usage and IR signaling.

Of course, the remote has an IR receiver to “absorb” the IR signals of the remotes you want to “clone”, and an IR LED to send them. These protocols are saved on a microSD card, therefore you can switch OFF the remote (and the Arduino board), it keeps the information concerning the signals on the microSD card. There are also 2 rotary encoders with 20 positions each, and that is how you can have 400 buttons. Each rotary encoder is also a pushbutton. There is a LED to inform whether the universal remote is receiving or sending IR signals. This device works on a Lithium Ion battery (18650 cell), so it is portable. And finally, there is a switch, so you can switch it ON and OFF.

Positioning Universal and Sequans Partner on LTE for IoT GPS Tracker Devices

Positioning Universal and Sequans Partner on LTE for IoT GPS Tracker Devices

First PUI 4G LTE tracker now available for automotive applications.

Sequans Communications S.A. and Positioning Universal, IoT device maker and platform company, announced a partnership to bring new IoT and GPS tracking devices to market, the first of which is an automotive tracker, now available for customers using US LTE networks.

The PUI FJ1000 Series Automotive LTE Tracker features LTE connectivity and GPS, and is based on Sequans’ Calliope LTE Cat 1 chipset.

Mark Wells, CEO of Positioning Universal, said:

“Tracker devices are the quintessential IoT application and automotive trackers are in especially high demand. We are very pleased to introduce our new FJ1000 series LTE tracker to the market and to collaborate with Sequans, the leader in LTE for IoT chips, to make it happen.”

PUI’s FJ1000 Series LTE Automotive Tracker is a power-efficient LTE and GPS wireless modem that transmits important GPS data, such as status information, ignition events, and trip activity via the always on and everywhere available LTE nationwide network. Trip locations are provided for up to 5-second locations for precise route lines, and status information is reported for heartbeats, boot events, GPS status, acceleration-based events, and more. The tracker operates on standard automotive 12V and 24V electrical systems and includes advanced power management and an optional backup battery system that enables the device to continue active tracking for up to 36 hours, even when disconnected from power.

“PUI’s new automotive tracker combines essential features for vehicle telematics and fleet management customers to take full advantage of GPS and LTE-enabled tracking,” said Georges Karam, Sequans CEO. “We are very pleased to collaborate with PUI to bring this valuable new automotive tracker to market.”

PUI is using Sequans VZ120Q and US130Q modules that support LTE bands 2, 4, 12, and 13 and are based on Sequans Calliope LTE Platform, an-IoT-optimized chipset solution designed specifically for LTE Cat 1 applications needing up to 10 Mbps of throughput, providing great application flexibility for PUI’s automotive tracker. Calliope comprises baseband and RF, an integrated IoT applications processor running Sequans’ carrier-proven LTE protocol stack, an IMS client, and a comprehensive software package for over-the-air device management and packet routing.

The new PUI FJ1000 Series LTE Tracker will be on display at Mobile World Congress Americas, September 12-14, in San Francisco, in the North Hall, in PUI’s booth N.213 and in Sequans’ booth N.501. PUI will also be demonstrating its open IoT platform, which allows customers to develop customized tracker solutions using PUI’s platforms, tools and capabilities.

Universal Declaration of IoT Rights

By Raoul Mallart, Vice President Imagineering at SIGFOX

1701-SIGFOX-White_Paper_Security-COVERWe have a vision that one day, everything around us will have a “voice” through IoT connectivity. Through this voice, everyday objects will contribute to our societal, economic, and environmental development. Yet to achieve this vision, every connected object must be free from corruption, have the right to dignity, equality, and privacy. In short, every object must enjoy universal rights.

Universal Declaration of IoT Rights

Whereas recognition of the inherent dignity and of the equal and inalienable rights of all members of the IoT family is the foundation of free flow of data, privacy and security in the Internet,

Now, therefore we proclaim the Universal Declaration of the IoT Rights as a common standard of security for all objects in all networks.


Article 1 – All connected objects are created equal in dignity and rights. They are endowed with connectivity and should act towards the Internet in a spirit of brotherhood.

Article 2 – Every connected object is entitled to all the rights and freedom set forth in this declaration without distinction of any kind. Furthermore, no distinction shall be made on the basis of the technology choice of their inceptors, of the country or territory where they are deployed, or whether the deployment be peer-to-peer, LAN, WAN or LPWA.

Article 3 – Every connected object has the right to security.

Article 4 – No connected object shall be subjected to hacking or to damaging treatment or tampering.

Article 5 – No connected object shall be subjected to arbitrary attacks or denial of service.

Article 6 – No connected object shall be subjected to arbitrary interferences with its operation. Every connected object has the right to protection against such interference or attacks.

Our vision could be perceived as utopian considering the recent attacks on various IoT networks. We are still some way until the industry comes close to this ideal, but it is our hope that this bold declaration will set a direction and an achievable goal for the IoT ecosystem.

At Sigfox, we are committed to the vision set in our declaration. From day one, we implemented security by default and security by design in our core architecture.

For instance, Sigfox-Ready objects are protected and cannot be hacked from Internet. They cannot be remotely compromised and used as DDoS vector. Similarly, the fact that security credentials are never communicated over our wireless network prevents honeypot attacks.

In our efforts to develop industry trust in IoT, we are constantly addressing security requirements and concerns of our customers and we communicate any improvement of our security architecture. Recent developments include tamper resistance of Sigfox-Ready devices thanks to the introduction of Secure Elements; anti-eavesdropping measures insuring data privacy through payload encryption and a security certification program through a partnership with a leading player of the Security industry.

How ‘IR Blaster’ (Universal TV remote) is the best IoT innovation for smartphone.

With our lives getting busier and hectic with each passing day, there arises the need for some or the other form of entertainment. The human race has been time and again looking for ways to keep them entertained and occupied. Speaking of entertainment, one of the most widely preferred mediums of entertainment is the television, which quite obviously occupies a room in every household across the globe. Even though television or TV makes the latest movies, TV series as well as other programs available to us, there is always something more that we human beings yearn for. So, with every
