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 […]

Karl’s Home Automation Project – Part 4: MQTT Bridge Updated to Use YS-IRTM IR Receiver & Transmitter with NodeMCU

In a previous article, I wrote about an MQTT bridge by 1technophile. I added a DHT temperature and humidity sensor as well as a light sensor. Previously it included a software decoder to decode the IR signal. I never did test the IR transmitter on the gateway, as I didn’t have the parts. But thanks to IC Station, who sent me over a small YS-IRTM hardware based decoder and NodeMCU that I am writing about today. I have replaced the software based version with the YS-IRTM module in the latest update. I found this project challenging. I admit I am a little weak in my programming skills. It was difficult to find documentation but I found a forum talking about this device and basics of how it works. When an IR code is recognized it sends 3 hex codes via serial connection on the transmit pin. To transmit, it expects […]

MAXOAK K2 Laptop Power Bank Review – Part 2: Tests with Laptops, Phones and Development Boards

MAXOAK K2 is a large capacity (50,000 mAh) power bank designed for laptop with ~20V and 12V outputs, but it can also charge USB devices thanks to its 4 USB ports. Since I’ve already checkout the device and specifications in the first part of the review, I’ll report results from my tests with the power bank in the last couple of weeks. Since the power bank had some charge, more exactly between 50 and 75% (2x LEDs on, 1x LED blinking, 1x LED off), I decided to start by charging my phone, Vernee Apollo Lite, which is equipped with a 3,180 mAh battery. So I connected the phone to one of the two 5V/2.1A USB port, together with USB Charger Doctor to monitor voltage and current, and with 50% charge, the phone would draw around 5.07V @ 1.15 A. Note that the voltage and amperage will change depending on battery […]

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 […]

Creality CR-10 3D Printer Review – Part 1: Unboxing, Setup, and First Prints

Today we are going to take a first look at the Creality CR-10 3D printer. This is a multipart series with the first part being unboxing and initial setup. I have no experience with 3D printing, and when I found out I would be doing this review I was ecstatic. It took a while to get shipped because of the wild popularity at Gearbest. I believe supply has caught up with demand. While waiting I read as much as I could about 3D printing. and I am glad I did. Creality CR-10 3D Printer Specifications 300 x 300 x 400mm build volume Nozzle diameter: 0.4mm Memory card offline print: SD card Prints up to 80mm/s (but slower is better) File format: G-code, JPG, OBJ, STL (I have only done g-code) 1.75mm Software – Cura; octoprint compatible CR-10 3D Printer Unboxing and Setup I had the CR-10 assembled and printing in […]

Sen5 Dual Tuner Android Set-top Box Review – Part 1: Unboxing and Teardown

There are only a few companies manufacturing Android TV boxes with tuners with names like VideoStrong and WeTek coming to mind. Shenzhen Sen5 Technology is another one, and the company sent me one of their DVB combo Android TV boxes for review without providing that many details. So let’s have a look at what I received. Sen5 Android Combo STB Unboxing The product might be not ready for retail just yet, as I received it in an old carton box. Once I remove all the bubble wraps, I ended up with the device, an IR remote control, and a 12V/1.5A power supply. Once the product is actually launched I’d expect you’d receive a retail package and a user’s manual too. The box itself is made of plastic with plenty of randomly arranged (ventilation) holes on the top. The front panel comes with an IR window and a “Standby button”, one […]

NanoPi NEO2 Board Benchmarks with Ubuntu 16.04.2 using Linux 3.10 and Linux 4.10

I’ve received NanoPi NEO 2 boards, add-boards and sensor modules last week, where we could see how small the boards were, and how it could be suitable for IoT projects or “hardware hacking” education. Before testing the board with the add-ons, I have to select the image to run on the board, and currently we have two choices: Ubuntu 16.04.2 FriendlyELEC image with Linux 3.10 “legacy” kernel, or Armbian Ubuntu 16.04.2 Xenial nightly build with Linux 4.10 “mainline” kernel. So I decided to try both: dfssf nanopi-neo2-ubuntu-core-qte-sd4g-20170329.img.zip (296 MB) is the image from FriendlyELEC (previously FriendlyARM) Armbian_5.27.170401_Nanopineo2_Ubuntu_xenial_dev_4.10.0.7z (222 Mb) is the image from Armbian, which I downloaded on March 31st despite the filename including “170401” string You can flash the image with Win32DiskImager (Windows) or dd (linux) to a micro SD card the usual way, and while I’ve never personally had troubles with dd, I’ve been told Etcher was better, […]
