ONENUTS Nut 1 TV Box Specifications, Unbagging and Teardown

I first discovered Shenzhen Tomato’s ONENUTS brand through ONENUTS T1 3-in-1 projector, tablet, and mini PC, but the company has now launched a new product with ONENUTS Nut 1 Android TV box powered by Amlogic S912 processor, and the usual 2GB RAM and 16GB storage, but the product stands out a little thanks to its presentation as we’ll see below.

Getting Started with RabbitMax Flex IoT and Automation Hat for Raspberry Pi

At the beginning of the month I showed how to assemble RabbitMax Flex, a Raspberry Pi HAT compliant add-on board for Raspberry Pi boards with 40-pin header, that targets IoT and home automation project with its relay, IR transmitter and receiver, I2C headers for sensors, buzzer, RGB LED, and more.  Since I’ve already described the hardware, I’ve spend some time this week-end following the user’s guide to play around with the board using a Raspberry Pi 2 board, and try various features. The user’s manual explains that you need the latest version of Raspbian, but I’d not played with my Raspberry Pi 2 board for a while, so the kernel and firmware were quite old:

So the first thing I had to do was to upgrade Raspbian. There are basically two options to upgrade, either downloading and dumping the latest Raspbian firmware image to your micro SD card, and […]

Pine64 PADI IoT Stamp WiFi IoT Kit Review – Part 1: Hardware, Debuggers, and Soldering

Back in September, Pine64 unveiled their $2 PADI IoT Stamp based on Realtek RTL8710 ARM Cortex M3 WiFi SoC aiming to compete with Expressif ESP8266 solutions.  The company has now sent me their complete kit for review, which beside the module itself includes a breakout board kit, and some hardware debug tools. In the first part of the review, I’ll check out the hardware, and solder the kit. I received a package with four antistatic bags. From top left to bottom right, we have PADI IoT Stamp, JLINK-OB debugger based on an STM32 MCU with some jumper wires (aka Dupont cables) for SWD signals, and a USB cable to your computer in order to flash the firmware or do some bare metal programming, a breakout board kit including two headers, a RED LED, and a resistor, and finally a USB to Serial board based on CH340G with 4 jumper wires […]

Beelink GT1 TV Box Review – Part 2: Android Marshmallow Firmware

I’ve previously reviewed other Amlogic S912 TV boxes such as M12N MXQ Plus or Qintaix Q912, but Beelink GT1 has the advantage of being quite cheaper at $56 and up, but still come with many of the same features as more expensive devices. I’ve already posted pictures, and checked out the hardware design in the first part of Beelink GT1 review, so in the second part I’ll report my experience with Android, including video and audio capabilities, hardware features testing, and some benchmarks. First Boot, OTA Firmware Update, Settings, and First Impressions The device comes with two USB ports only, so I connected a USB hard drive to one of the port, and a USB hub to the other with the RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, as well as a USB keyboard to take screenshots. I completed the setup by adding […]

MUSES-α & MUSES-β DVB-T/C, ISDB-T, DTMB & ATSC Modulator Boards Review – Part 1: The Hardware

V-Bridge Muses digital TV modulator boards launched on Kickstarter earlier this month, with the cheaper $200 MUSES-α board modulating video from a PC, and $600 MUSES-β turnkey solution capable of broadcasting HDMI or AV + stereo input to various digital TV standards including DVB-T/C, ATSC/QAM, DTMB, and ISDB-T/TB without the help of a computer. The company sent me the two hardware kits for evaluation and review on CNX Software, and today I’ll start by showing off the hardware I received. I got 3 packages and a F-female to F-female cable, which means you can connect the board directly to your TV tuner without having to rely on actual RF signals, and potential legal issues that goes with it. The first package I open if for the PC modulator kit that include MUSES-α board, an “RF” board, as a USB cable to connect to your computer. MUSES-α board features Vatek A1 […]

Zidoo X9S Android Media Center Review – Part 2: Android Firmware & OpenWrt (NAS Functions)

Zidoo X9S is more than a simple Android TV box, as it supports NAS function via OpenWrt running simultaneously with Android 6.0 and its USB 3.0 and SATA ports, as well as HDMI input function capable of recording and broadcasting videos, and supporting Picture-in-picture, so I find “Android Media Center” better fit the description for this device. I’ve already taken pictures of the Zidoo X9S and its board in the first part of the review, so I’ll test both Android 6.0 & OpenWrt firmware, and the most of the features in the second part of the review. Initial Setup and First Boot I connected the usual accessories and cables to the box including a USB 3.0 hard drive, HDMI and Ethernet cables, USB RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, and a USB keyboard to take screenshots. I also added a 1TB SATA […]
