SiFive Introduces HiFive Unleashed RISC-V Linux Development Board (Crowdfunding)

RISC-V free and open architecture has gained traction in the last couple of years. SiFive has been one of the most active companies with RISC-V architecture, introducing Freedom U500 and E500 open source RISC-V SoCs in the summer of 2016, before launching their own HiFive1 Arduino compatible board, and later the official Arduino Cinque board. That’s fine if you are happy with MCU class boards, but RISC-V is getting into more powerful processors, and recently got initial support o Linux 4.15, so it should come as no surprise the company has now launched HiFive Unleashed, the first RISC-V-based, Linux-capable development board. HiFive Unleashed key features and specifications: SoC – SiFive Freedom U540 with 4x U54 RV64GC application cores @ up to 1.5GHz with Sv39 virtual memory support, 1x E51 RV64IMAC Management Core, 2 MB L2 cache; 28 nm TSMC process System Memory – 8GB DDR4 with ECC Storage – 32MB […]

M1 3D Holographic Display is a Fan Showing Holograms from Videos and Photos

I’ve been watching or reading news about holographic displays recently where you can watch 3D objects into space without 3D glasses. Not the IoT gateway with an holographic maid, but I watched some hologram demos recently, and RED is bringing an (expensive) Android phone – called Hydrgen – to market with an holographic display. Today, I was made aware that you can buy some sort of fan to produce holograms designed in your own computer. It’s referred to “M1 Naked Eye 3D Holographic Advertising” in several shops, and as the name implies it’s likely mostly useful for businesses rather than home users. Hardware specifications: LEDs – 224x RGB0805 LEDs, 100,000 hours life Display – 16.53″ with 450 x 224 pixel resolution; viewing angle: 150° Supported media mp4, avi, rmvb, mkv, gif, jpg, png 3D effect media – MP4 or GIF with black background Storage – micro SD slot for media […]

Evercell Thermal Energy Harvester to Power Battery-less IoT Wireless Sensors

In order to be successful the Internet of Things needs to be extremely inexpensive per node, and the problem is that most remote sensors are non powered by batteries, which either needs to be replaced or recharged, which involve maintenance costs. One ideal solution is battery-less IoT sensor nodes, that do not need any battery, and instead rely on energy harvesting. The idea is easier said that done, especially if you intend to do it cheaply. While there have been solutions provided over the years for example using vibration energy harvesting or water flow, battery-less devices are still not that common, but companies still bring new energy harvesting devices to market. One of those is Face International’s Evercell thermal energy harvester that leverages the temperature difference within a material to generate electricity, as long as ambient temperature is above absolute zero. The company plans to manufacture various models of their […]

Digi Introduces XBee3 IoT Modules with New Micro Form Factor, RF and Cellular IoT Connectivity

Digi International has just announced the Digi XBee3 series of RF modules and cellular IoT modules. The modules will be available in the existing Digi XBee SMT amd through-hole form factor, as well as a new micro form factor (19×13 mm) that’s about a third of the size of the original XBee RF module. The RF modules will first come with ZigBee 3.0 and IEEE 802.15 support, but Bluetooth LE will be available through a firmware update later on, and WiFi and DigiMesh version will be brought to markets too. The first cellular module supports LTE Cat.1, but the company will eventually launch NB-IoT and eMTC (LTE Cat M) versions for Europe and the US respectively. Some of the shared key capabilities listed by the company: Over-the-air (OTA) changes to devices in the field for bug fixes and new features Dynamically reconfigurable, based upon situation Establish business rules to aggregate, store, […]

UltraZed-EG SoM and Starter Kit Feature Xilinx Zynq UltraScale+ ZU3EG MPSoC

Xilinx Zynq UltraScale+ Arm Cortex A53 + FPGA MPSoCs were announced in 2015, with actual products launched in early 2017 such as AXIOM development board or Trenz Electronic TE0808 UltraSOM+ system-on-module which are based on the ZU9EG model, and cost several thousand dollars. Recently, I wrote about Mycroft Mark II smart speaker based on a “quad core Xilinx processor”, and initially I assumed it was an Zynq UltraScale+ MPSoCs since those are the only Xilinx “quad core processors” I know of, but now I think it must be an unannounced part, since the company can’t provide the exact part number, and the price would be too low. Nevertheless, this lead me to check out if there was any lower cost boards based Xilinx Zynq UltraScale+ MPSoC with four Arm Cortex A53 cores, and ZU2EG is the entry-level part that matches this description. I could not find a ZU2EG development board, […]

Ericsson Unveils 5G Radio Dot for Better 5G Indoor Coverage

5G cellular technology is coming sometimes in 2019, before ramping up in 2020 in several countries. The new 3GPP standard will allow maximum bandwidth up to 10 Gigabit per second, and we’ve already seen announcements such as Snapdragon X50 5G Modem which will be able to reach up to 5 Gbps download speeds. 5G apparently works at either high bands starting at 28 GHz and up to 60 GHz, which means 5G signal might have a really hard time penetrating through walls or other obstacles, or at mid bands between 3.5 and 5 GHz which will still be a challenge compared to 4G LTE operating between 600 MHz and 3.5 GHz. That means that signal from outdoor base station won’t be able to penetrate in all building, so 5G indoor small cells will be necessary for good indoor coverage. Ericsson has already unveiled their own small cells with 5G radio […]

Intel Compute Cards Review – Windows 10 and Ubuntu 17.04 on CD1C64GK, CD1P64GK and CD1M3128MK

The Intel Compute Stick revolutionized the mini PC market through the introduction of x86 based processors making Windows available as an OS option. However, for Intel the biggest target market turned out to be business rather than consumer with digital signage being a key user. As a result Intel have responded with the introduction of the Intel Compute Card. So far they have released four versions of card: and they they differ from compute sticks by no longer being standalone mini PCs but dependent on a dock or host device. The card itself is relatively small with a footprint slightly larger than a standard credit card: and is distinguished by the back being printed with details about the card including the model: The lack of emphasis on the consumer market is also evident in the rather unobtrusive plain packaging: On the end that inserts into the dock or host device […]

Mycroft Mark II Smart Speaker / Voice Assistant Works with Open Source Software (Crowdfunding)

Smart speakers have gain a lot of traction over the last few years, but many of the solutions are based on Google Assistant or Amazon Alexa voice services, with both companies likely tracking your voice searches the same way they track your online searches to provide a “personalized experience” and sell you products or server ads that match your interests. If you don’t like being tracked that way, a solution is to use an open source voice assistant such as Mycroft, and install it on a Linux computer, Raspberry Pi 3 board, or Android device. The company also introduced Mark I reference hardware platform based on Raspberry Pi 2 in 2015, and while all those hardware options should be fine for the technically inclined, but not really suited to the typical end user, and AFAIK they all lack a microphone array for better hot word detection. So Mycroft has come […]
