Walabot MIMO Radar Board Can See Through Walls Thanks to Vayyar 3D Imaging Sensors

A few days ago, I wrote about Orbbec Astra 3D camera that can analyze distance and depth to form a 3D image of object. However, this solution uses an IR sensors, and while it can fulfill the needs of many application it does not allow to see through object, and that’s exactly what Walabot wideband MIMO radar board promises to do thanks to Vayyar 3D imaging sensor and a dozen of RF antennas. Some of the key features and preliminary specifications of Walabot board include: Vayyar VYYR2401 3D imaging sensor 12 (or is it 14?) non-contact antennas array system based on “Octopus A3 System on chip” Build in Tx/Rx linear polarized wide-band antennas from 3-10Ghz. On-board Cypress FX3 controller for communication and pre-processing EEPROM (for inventory and calibration information) Walabot interface connectors: Micro-USB 2.0 for high-rate data communication. Option to provide supply from USB. Single supply voltage 4.5-5.5v input for […]

FLIF Lossless Image Format Claims to Outperform PNG, JPEG2000, WebP, and BPG

FLIF, which stands for Free Lossless Image Format, is a new lossless image format that is said to provide better compression ration than PNG, lossless JPEG2000, lossless WebP, and lossless BPG for all king of images including medical images, geographical maps, cliparts and so on. Beside being lossless, FLIF is also progressive, so a lower quality version of the image can be displayed early while the download is still in progress. The developer has uploaded a video comparing how a PNG image and FLIF image would load in a slow network. Other FLIF features include: Lossless compression Greyscale, RGB, RGBA Up to 16 bits color depth per channel (high dynamic range) Interlaced (default) or non-interlaced Animation support “Encoding and decoding speeds are not blazingly fast, but they are in the right ballpark” Based on MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding) algorithm developed by Jon Sneyers and Pieter Wuille. (However details […]

Archos Introduces Free PicoWAN IoT Gateway, Costing 75 Cents Per Year Per Connected Device

The Internet of Things is promising billions of connected devices in the next few years, and while devices at home can usually connect through your broadband connection at no extra cost, devices on the field may need to use cellular connectivity and cheap 2G network are being phased out by Telcos. Weightless, operating over white space frequencies, is one of several solutions proposed to connect IoT objects over longer distances, but Archos has their own project with PicoWAN pico-gateways using LoRa(WAN) protocol which allows for several kilometers range. PicoWAN would plug into your wall socket, connect to your broadband network over WiFI and offer connectivity to various “things” over LoRa. Creating a cellular network is expensive, due to the costs of base stations, but PicoWAN is so cheap, 100 times cheap than traditional base stations, that Archos plans to giveaway 200,000 gateways across Europe to create an IoT network. That […]

Xiaomi Mi Smart Remote Center Review

Xiaomi Mi Smart Remote Center is a tiny box with WiFi connectivity and IR transmitters that is used to control infrared enabled devices such as TVs, medai players, air conditioners and more with your Android smartphone. The good thing is that it only costs $20, so I asked GearBest to send a sample to check it out, which they did. I’ll start this review by checking out the hardware, before running MiHome app to control a television and air conditioner. Xiaomi Mi Smart Remote Center Unboxing and Teardown The package is just a cardboard box with Mi logo. Once you open the page there’s a sticker with the QR core redirecting to MiHome app. You can peel it off, and take the box out of the package, where you’ll also find a USB to micro USB cable for power, and a user’s manual in Chinese only. To open the device […]
