AIO Robotics Zeus 3D Printer, Scanner, and Editor Allows You to Print and Copy 3D Objects Without a PC

The 3D printer maket is brutal. Many people have tried to designed their own 3D printer, and launch them through crowdfunding campaigns, but the rate is failure is very high, and some cases, scams are also reported. When I covered BlackSmith Genesis 3D Printer, Scanner and Copier in 2015,  I was hopeful it would become successful, as it solves one the main problem with 3D printing: the high skill sets required to operate the device as it would just operate as a 3D copier. Place the object inside the 3D printer, press copy, and a few minutes or hours later, you get a copy of the object without having to learn about 3D design or G-code format. But today, I noticed the website account at expired, and the 3D copier was nowhere to be found, so it looks like another failure. Around the same time in 2015, another company called […]

Zotac CI327 Nano Apollo Lake Fanless mini PC Features HDMI 2.0, DisplayPort 1.2, and VGA Video Outputs

While many Apollo Lake mini PCs have been launched, few support 4K @ 60 Hz video output, but Zotac CI327 Nano mini PC does even better than that thanks to HDMI 2.0 and DisplayPort 1.2 outputs allowing for dual 4K UHD @ 60 Hz setups, and it also adds an extra VGA port to enable triple display setups. The rest of the specifications are not too bad either with three models CI327 Nano (windows / no windows) and CI327 Nano Plus with slightly different hardware specifications: SoC – Intel Celeron N3450 quad-core  processor @ 1.1GHz / 2.2GHz with Intel HD Graphics 500 System Memory Nano with Windows and Nano PLUS – 4GB DDR3L (one slot occupied, up to 8GB) Nano – 2x 204-pin DDR3L-1866 SO-DIMM slots (up to 8GB) Storage – 1x 2.5″ SATA 6.0 Gbps SSD/HDD slot; 3-in-1 (SD/SDHC/SDXC); Nano with WINDOWS only: 32GB M.2 on-board SATA SSD Video […]

U5 PVR Deluxe Android Set-Top Box Review – Part 1: Specs, Unboxing, Teardown, and SATA HDD Assembly

Last year, I reviewed U4 Quad Hybrid, an Android TV box powered by Hisilicon Hi3796M quad core Cortex A7 processor and with a combo DVB-T2/C + DVB-S2 tuner. with digital TV tuner. It worked pretty well, except for a few bugs here and there, the processor is not the most powerful, and video output & decoding is limited to 4K  @ 30Hz. The company – Shenzhen Vivant Technology – is now back with a new model called U5 PVR powered by a more powerful Hisilicon Hi3798C V200 quad core Cortex A53 processor with fast interfaces like USB 3.0, SATA, and Gigabit Ethernet, as well as support for 4K @ 60Hz via a HDMI 2.0a interface. There are actually three variations of U5 PVR with Deluxe/Slim/Normal models, and the company sent me U5 PVR Deluxe model for review. As usual, after listing the specifications, I’ll start the review by checking out […]

Yundoo Y8 (Rockchip RK3399) TV Box Review – Part 1: Unboxing and Teardown

Rockchip first unveiled RK3399 hexa-core processor at the beginning of 2016, but we had to wait longer than expected to get devices to play with. The first retail product based on the processor is really Samsung Chromebook Plus, and we only saw a few TV boxes for pre-sale in January such as Yundoo Y8 or R-TV Box K99, and with the first shipments occurring in March. However, I’ve also noticed many companies postponed the launch of the RK3399 mini PC/TV box, and no company contacted me for review so far, so I had no rush because that probably means the boxes were not quite ready. But starting at the beginning of next month, more companies will start selling their model, and GearBest proposed to send me Yundoo Y8 model with 4GB RAm, 32GB flash, and decided to give it a go. In this first part of the review, I’ll only […]

EEMBC IoT-Connect is a Family of Benchmarks Designed To Test the Power Efficiency of IoT Devices

EEMBC, the Embedded Microprocessor Benchmark Consortium, has been providing benchmarks for embedded systems since 1996, including ULPBench helping to rank micro-controllers by their power efficiency. But with the Internet of Things gaining traction, it’s important to test more than just the MCU core’s power efficiency, and having a benchmark taking sensors and connectivity into account would be useful. That’s exactly what EEMC IoT-Connect benchmark family aims for with the three main characteristics: Provides flexibility to accommodate various communication protocols (e.g. Bluetooth, Thread, LoRa, WiFi) Portable to work with any vendor’s microcontroller and radio-module products Compatible with EEMBC ULPBench and EEMBC IoT-Secure benchmarks The first benchmark of the family is IoTMark-BLE connectivity profile that supports Bluetooth (LE) MCUs. The benchmark requires fixed payload size, frequency of transmission, and transmit power, and performs a complete sequence of event ranging from sensor reading, to BLE notifications, and command write and CRC. The IoT-Connect […]

ESP8266, Mongoose OS & Grove Sensors – An Alternative Solution for Hackathons

CNXSoft: This is a guest post by Cesanta If you walked into any Hardware hackathon over the last year, you would see they are about innovation and bringing new ideas to this world and most of them are centered around the connected devices nowadays. However, just walk the floor, talk to the teams and you can quickly see an elephant in the room. The Hackathons are about connected devices, but with the ‘recommended’ and frequently sponsored hardware distributed to the teams such as Intel Galileo, Raspberry Pi, etc…. developers may struggle for a long time to even connect it to the cloud! Not to mention the innovation is usually hindered by a tedious environment setup which takes hours, things to learn about the specific hardware and how it can be programmed using low level languages. So many teams spent most of the time fighting with those issues and oftentimes still […]

Rikomagic RKM R1 Mini Projector Review – Part 2: Android Firmware, Kodi, Touchpad, and HDMI Input

Rikomagic RKM R1 is a projector running Android 4.4.4, and powered by Rockchip RK3128 quad core Cortex A7 processor with 1GB RAM, and 32GB storage. It has a particular feature as it comes with a touchpad on the top of the case as we’ve seen in the unboxing and teardown part of the Rikomagic R1 review. Today, I’ll report my experience with the projector playing games in Android, 1080p videos with Kodi 14.2, using the touchpad, and connecting a laptop through the HDMI input port. I’ll also run some benchmarks as usual. RKM R1 Android User Experience and HDMI Input I wanted to relax and use the projector on the bed pointing to the ceiling. RKM R1 comes with a tripod, but it’s quite small, not the projector would fall off, so I used my own tripod, connected a USB keyboard, and the USB RF dongle for Tronsmart Mars G01 […]

Cambrionix PowerPad 15S is a 15-Port USB Hub with 2.1A Output, Control API, Serial Console, Power Consumption Monitoring

Many development boards are powered over USB, usually via a micro USB ports, and if you have one board, you’d just use a 5V USB adapter with the right amperage, and it will work fine as long as you have a low resistance USB cable (AWG20 cables recommended for higher loads).  But when you start to running multiple boards using power strips with USB adapter start to take space, so USB hubs are much more convenient. However, you need to find one that delivers enough power, is reliable, and possible allows per port power control. The guys at LAVA (Linaro Automated Validation Architecture) are using a lot of boards to validate software developed by Linaro and their members, with the boards having to run 24/7, and they had various misfortunes with USB hubs, but as Dave Pigott reports they’ve now found that USB hub of their dream with a 15-port […]
