Measy RCA220 is a $35 Wireless AV Transmitter / Receiver Kit with a 200m Range

There are several ways to send video & audio data over a distance without using long cables, from professional DVB-T transmitters with up to 10km range, to cheaper DIY SDR solutions with a shorter range , and HDMI transmitters leveraging your existing electrical cables. Those all work for different target applications (drones, video signal extender), but cost at least a few hundred dollars. If you just intend to transmit composite video (PAL/NTSC) and audio within a house or building, Measy RCA220 will be a more cost effective solution with a range of up to 200 meters. Measy RCA220 AV transmitter / receiver specifications: Connectivity – 2.4GHz wireless transmission with up to 200m range; built-in antenna, 8x selectable channels Video / Audio Ports Transmitter – RCA composite input, 2x RCA L/R audio input Receiver – RCA composite output, 2x RCA L/R audio output Misc – IR jack, channel selection button, front […]

Ugoos Releases Android 7.1.2 Nougat (Beta) for Rockchip RK3288 TV Boxes

Rockchip RK3288 quad core Arm Cortex A17 processor was first released in early 2014 with Android 4.4, and TV boxes that are still sold with the processor – e.g. Lenovo G66 – often still come with Android 4.4 or Android 5.1, and development boards do barely better as ASUS Tinker Board supports Android 6.0.1, while Firefly-RK3288 may never get its expected Marshmallow update. However, Ugoos decided to support their RK3288 TV boxes for a longer time, and has now released a beta version of Android 7.1.2 firmware for Ugoos UM3, UT3, and UT3s TV boxes. Some of the features and Ugoos specific settings available in the firmware include: CIFS & NFS Clients Support, Samba Server Masked HDMI Screen Rotation Root access Hardware Monitor Wireless Assistant Gamepad Settings Debug Settings User Scripts USB Mode Settings If you want more details about what each setting does, read the post about Ugoos settings.

RockPro64 Board is Now Available for $59.99 and Up for Early Adopters & Developers

Several Rockchip RK3399 development boards and SBCs were announced or launched in Q4 2017 / Q1 2018, including Orange Pi RK3399, ODROID-N1, Rock960, etc… RockPro64 was the most aggressively priced of the lot as it was expected to launch for about $60. The good news is that Pine 64 is now selling the first production batch for $59.99 (2GB RAM) or $79.99 (4GB RAM). The less good news is that software is still being worked on so the company only recommends it for early adapters and developers. RockPro64 specifications have changed a bit since the board now comes with LPDDR4 memory instead of LPDDR3: SoC – Rockchip RK3399 hexa-core processor with 2x ARM Cortex A72 cores up to 2.0 GHz, 4x Cortex A53 cores, and an Arm Mali-T860 MP4 GPU System Memory – 2 or 4 GB LPDDR4, dual channel Storage – eMMC flash module (up to 128 GB), micro […]

Eufy EverCam Full HD Waterproof WiFi Security Camera Works for Up to a Year on a Single Battery Charge

Wired security cameras can be troublesome to installed due to the cabling required, but luckily there are solutions to avoid all those long cables with solar powered IP cameras, or battery powered IP cameras. A few years ago I wrote about Immedia Blink WiFi HD camera that claimed to last a year on a charge, and despite several complains on Kickstarter, they seem to still be in business. There’s now a more advanced model by Eufy – an Anker brand – that supports 1080p video recording with motion sensing and face recognition, that also lasts up to one year on a charge, and offers free storage. Eufy EverCam specifications: Resolution – 1080p Video Format – H.264 High profile Image Sensor – Sony Exmor IMX323, 1/2 9-inch Field of View (FoV) – 140° Night Vision Range – up to 10 meters Digital Pan & Zoom – Yes, up to 8x Motion […]

Pepper Jobs W10 GYRO is an Air Mouse Designed for Windows 10

Air mice are remote controls including motion sensors allowing to wave the remote to emulate a mouse, as well as some buttons like in a standard remote control, and in some cases a keyboard. Some people do not like this type of user input, but that’s my favorite way (I’m using MINIX NEO A2 Lite) of controlling TV boxes, as it provides a mouse pointer, a QWERTY keyboard, and various keys including volume keys and a D-Pad. The air mouse is also compatible with computers running Windows, Ubuntu, or other operating systems but some operations can not easily be done as the “Windows” key is missing, and shortcuts such as Alt+Tab are not possible. The guys at Pepper Jobs must have had the same kind of problem, as they’ve designed an air mouse working better with Windows 10 with keys to launch the default web browser, Task Manager, File Explorer, […]

Ubuntu 18.04 Released – What’s New?

Canonical should release Ubuntu 18.04 “Bionic Beaver” long term support distribution later today. One of the most obvious change compared to Ubuntu 16.04 is the switch from Unity to GNOME 3.28 resulting in a fairly different user interface, although the company tried to keep the look-and-feel are close of the Unity version as possible. There are still some differences such as the dash now appearing on the top center of the screen. Eventually, Ubuntu 18.04 Desktop ISO file will be found on Ubuntu website, but in the meantime, I could update an Ubuntu 17.10 virtual machine to Ubuntu 18.04 using the following commands:

sudo apt update 
sudo apt dist-upgrade 
sudo do-release-upgrade -d

sudo apt update

sudo apt dist-upgrade

sudo do-release-upgrade -d

I’ll update my main machine a little later, maybe after the dot release in July, and my server after that, just in case some bugs have gone unnoticed. You’ll be greeted with a “What’s new in Ubuntu” window after upgrade showing the main part of the […]
