Yeelight Smart LED Bulb 1S (Color) Review with Android App and Google (Local) Home

Yeelight Smart LED Bulb Google Local Home

Last summer, Google released the Local Home SDK developer preview which allows developers to run actions and use resources on the local device rather than in the Cloud for lower latency. One company that updated its devices is Yeelight whose WiFi smart lights have now been enhanced with the Google Local Home SDK helping deliver a latency of less than 0.3 seconds, so you don’t need to wait after your voice command has been processed by Google Assistant. The company contacted me to test the new feature and had GearBest sent a sample of Yeelight Smart LED Bulb 1S (Color) for review. I have never tested Yeelight devices so I’ll start with an unboxing, testing with the Android app, before trying it out with Google Home and Google Assistant. Unboxing of Yeelight Smart LED Bulb 1S (Color) The package has some useful information about the light bulb including some specifications […]

Reolink Argus PT Review – A Solar powered Pan-Tilt Security Camera

Last year, I reviewed Reolink Argus Eco solar powered security camera, and I’m still using it to date. It’s working fairly well, although sometimes motion detection will not be triggered, or triggered too slowly so it’s not impossible to miss important footage. The PIR function can be tweaked so maybe it’s just a question of finding the right settings for a given location. Nevertheless, the company has now launched a new model called Reolinkg Argus PT that is very similar to the Argus Ego but with PT (Pan, Tilt) function, and I received a sample for review. Since both models are so similar, I recommend reading Argus Eco review first, as I’ll focus on the differences. Reolink Argus PT Unboxing I received two packages like las time: the camera itself, and Reolink solar panel. The camera comes with a WiFi antenna, a wall-mounting set, a USB cable, and some documentation. […]

Ntablet Android & Linux Tablet Features a Replaceable RK3288 CPU Module, GPIO Board

Most tablets on the market either run Android or Windows, and while some have tried to launch Linux tablets, none of the products have really caught on, although the upcoming PINETAB might change that. Another option might be Ntablet 7″ tablet that runs either Android, Debian or WebOS Linux operating systems, but also offers some innovative features such as a replaceable Rockchip RK3288 CPU module, and an external GPIO board for makers. Ntablet hardware specifications: SoC – Rockchip RK3288 quad-core Cortex-A17 processor @ 1.8 GHz with Mali-T760 quad-core GPU System Memory – 2GB LPDDR3 Storage – 16GB eMMC flash, MicroSD card slot up to 32GB Display – 7″ touchscreen IPS display with 1920×1200 resolution Video Output – Micro HDMI port Audio – 3.5mm headphone jack Camera – 5MP front-facing camera (OV5648 sensor) Connectivity – 802.11b/g/n/ac WiFi 5 and Bluetooth 4.0 via Ampak AP6255 module USB – 1x USB 2.0 port, […]

Semtech LoRa Asset Tracking Reference Kit Includes one LoRaWAN Gateway, Six Waterproof GPS Trackers

LoRa Asset Tracking Reference Kit Gateway

The Things Conference is taking place now until January 31, so we should expect a few LoRaWAN announcements, and yesterday we covered Semtech LLCC68 LoRa transceiver for smart home applications, but the company also introduced a LoRa asset tracking reference kit to ease the deployment and evaluation of LoRa based tracking solutions. The kit is comprised of one LoRaWAN gateway, and six waterproof trackers with GPS and LoRa connectivity which everything supposed to work out of the box. The gateway, as shown above, comes with LoRa, cellular and GPS antennas, as well as a PoE power supply. It ships with a pre-configured SIM card to connect to the cloud platform over 3G/4G. Six industrial LoRaWAN-based GPS trackers are also included with the kit. Each comes with a battery but the trackers need to be activated by the user. Interestingly they are not using a button to turn on and off […]

LibreRouter is an Open-Source Hardware Router for Community Networks

Battlemesh (aka the Wireless Battle of the Mesh) is an event that aims at bringing together people from across the world to test the performance of different routing protocols for ad-hoc networks. While BattleMesh v12 took place in Paris in July 2019, I’ve just been informed that presentation videos were now out. There are talks about OpenWrt, mesh networks, and communities, but one talk brought a project I had not looked into details yet. Originated from Argentina, LibreRouter is described as an open-source hardware router designed for community networks that are organized by a group of people such as neighbors in order to share local and other content without a profit motive. LibreRouter LR1 specifications: SoC – Qualcomm Atheros QCA9558 MIPS processor @ 750 MHz System Memory – 128 MB DDR RAM Storage – 16 MB Flash MCU – Microchip ATTiny13 8-bitAVR MCU used as hardware watchdog to handle failed […]

ESP Open Source Research Platform Enables the Design of RISC-V & Sparc SoC’s with Accelerators

FOSDEM 2020 will take place next week, and there will be several interesting talks about open-source hardware and software development. One of those is entitled “Open ESP – The Heterogeneous Open-Source Platform for Developing RISC-V Systems” with an excerpt of the abstract reading: ESP is an open-source research platform for RISC-V systems-on-chip that integrates many hardware accelerators. ESP provides a vertically integrated design flow from software development and hardware integration to full-system prototyping on FPGA. For application developers, it offers domain-specific automated solutions to synthesize new accelerators for their software and map it onto the heterogeneous SoC architecture. For hardware engineers, it offers automated solutions to integrate their accelerator designs into the complete SoC. If we go to the official website, we can see ESP (Embedded Scalable Platform) actually supports both 32-bit Leon3 (Sparc) and 64-bit Ariane (RISC-V) cores, and various hardware accelerators from the platform or third parties. Highlights: […]

Hisense A5 5.84″ e-Paper Android Smartphone Promises Up to 10-Day Battery Life

We’ve previously covered smartphones with a black and white e-Paper display usually placed on the back of the phone, while a traditional full-color display is placed at the front. Some models include Yotaphone 2 and Hisense A2, and the advantage of the e-Ink display is that you can extend battery life, quickly check notifications without unlocking your phone, reads book even in bright lights, etc.. but the cost goes up quite a bit since the manufacturers have to integrate two displays in their devices. Hisense A5 does completely away with the traditional color display and replaces it with a 5.84″ e-Paper display with 1440×720 resolution. The display is black and white, and the slow refresh rate of such display will make it impractical to watch videos and play most games, but if all you do is check emails, browsing the web, reading e-books, accessing social networks, and making phone calls […]
