RS485 & Raspberry Pi: Monitoring Power

Commercial data centers, lighting controls, utility rooms for buildings, and others need to keep a tab on their power consumption. The normal way to do this is by using electronic voltage meters and multi-branch current monitoring circuits. Vytas Sinkevicius wants to monitor power consumption using the ubiquitous single board computer, the Raspberry Pi (RBPi) as the main controller and the RS485 interface in a Branch Current Monitor (BCM) system. The heart of the power monitoring system is an Read more [...]

Orange Pi Prime – Another Rival for the Raspberry Pi 3

There is another Orange Pi among the branches of the highly productive Orange Pi tree belonging to Shenzhen Xunlong. This is the Orange Pi Prime—another rival to the most popular Raspberry Pi 3 (RBPi3). According to the year-end Linux hacker SBC roundup, half a dozen individual Orange Pi models were already existing, and if all the new variants are to be included, that number almost doubles. Proceeding at this rate, the company’s engineers will have checked out almost all possible combinations Read more [...]

Redefining MEMS with 3-D Interactive Projection

At the Mobile World Congress 2017, Bosch introduced a combo of a micro-scanner and projector, capable of turning any surface into a virtual user interface. Bosch is the world’s oldest and biggest manufacturer of micro-electro-mechanical systems (MEMS), and in its combo projector, it is using infrared for scanning and laser for projecting. Currently, engineers are using MEMS devices for a variety of gadgets, especially where a human-machine interface (HMI) is necessary. These include in-car heads-up Read more [...]

What is Special about the SkyX Drones?

SkyX is a drone maker from Markham, Ontario. This startup has some unique designs for industrial drones. For instance, the SkyOne drone of the company can take off and land without needing a runway. That is, its takeoff and landing is more like that of a helicopter, but in flight, the drone resembles an airplane more closely. In technical terms of the drone industry, the SkyOne has both Vertical Take Off and Landing (VTOL) and fixed-wing elements, while flying more than 40 km on one charge. SkyOne Read more [...]

OLED Lighting in the Auto Industry

In recent years, a number of industries have started using Organic Light-Emitting Diodes (OLEDs) in diverse ways. The automotive industry, in particular, has seen a huge potential in OLEDs. For instance, very soon Audi will be coming up with OLED taillights. At present Audi has presented prototypes of the taillights. At the LOPEC Congress, Audi provides advanced insights into the needs of the automotive industry that the deployment of OLEDs will require to meet, and the future of automotive lighting. So Read more [...]

What is a QLED?

Recently, Samsung has announced their new TV technology using QLEDs to counter the OLED TVs that LG and others have put on the market. QLED stands for Quantum dot LED, and though Samsung has been using the concept of quantum dots in its TVs for quite some years now, they claim they will be bringing out several flavors of the QLED technology. According to Samsung, QLEDs are transmissive, as LCDs are, and light goes through several layers to create an image on the surface of the screen. The company Read more [...]

Multicolored LEDs Create Secondary Colors

Any student of physics knows mixing two primary color light sources produces a secondary color. For instance, mixing the primary colors red and green creates the secondary color yellow. There are three primary colors—Red, Blue, and Green. This process is easily seen in tricolor and RGB LEDs. There is a disadvantage in this method. As two primary colors are necessary for generating a secondary color, two LEDs must remain turned on at the same time. Therefore, generating a secondary color means Read more [...]

Is there a 64-bit Raspberry Pi?

Although the arrival of the Raspberry Pi 3 (RBPi3) heralded a huge speed boost for the Linux hacker board, this $35, wireless-enabled single board computer did not signal a switch over to 64-bit ARM computing. Even though the hardware, following so many other SBCs at the time, was 64 bits, the default Linux distribution from the Raspberry Pi Foundation is still 32-bit. Eventually, there will be a changeover to 64-bit ARM firmware, as the technology offers significant improvements in performance. Read more [...]

Extending IoT with the Raspberry Pi

Recently, the Raspberry Foundation has updated its embedded Compute Module with a faster ARM processor. This will help developers and businesses build new IoT devices. The new Compute Module 3 (CM3) comes with a powerful new option and embedded compute capabilities for device makers interested in the Internet of Things (IoT). Although not to be confused with the Single Board Computer, the Raspberry Pi (RBPi), with which the CM3 also shared the latest update, is a tiny form-factor ARM-powered SBC Read more [...]

Powering the Pacemaker from Solar Energy

Those suffering from certain ailments of the heart, have to have a pacemaker installed. Surgeons place this tiny medical device in the chest or abdomen of the patient and it helps to control abnormal heart rhythms. The device generates electrical pulses and prompts the heart to beat at a normal rate. Power comes from implanted Lithium-iodide or Lithium anode cells, with Titanium as the encasing metal. The downside to this arrangement is the cells need replacement once they are discharged, and that Read more [...]
