Cheap Evil Tech – WiFi Deauther V2.0 Board and Autonomous Mini Killer Drones

Most technological advances usually improve life of people, and with the costs coming down dramatically over the years, available to more people. But technology can be used for bad, for example by governments and some hackers. Today, I’ve come across two cheap hardware devices that could be considered evil. The first one is actually pretty harmless and can be use for education, but disconnects you from your WiFi, which may bring severe physiological trauma to some people, but should not be life threatening, while the other is downright scary with cheap targeted killing machines. WiFi Deauther V2.0 board Specifications for this naughty little board: Wireless Module based on ESP8266 WiSoC USB – 1x Micro USB type changed, more stable. Expansion – 17-pin header with 1x ADC, 10x GPIOs, power pins Misc – 1x power switch, battery status LEDs Power Supply 5 to 12V via micro USB port Support for 18650 […]

JeVois-A33 Linux Computer Vision Camera Review – Part 2: Setup, Guided Tour, Documentation & Customization

Computer Vision, Artificial Intelligence, Machine Learning, etc.. are all terms we hear frequently those days. JeVois-A33 smart machine vision camera powered by Allwinner A33 quad core processor was launched last year on Indiegogo to bring such capabilities in a low power small form factor devices for example to use in robotics project. The company improved the software since the launch of the project, and has now sent me their tiny Linux camera developer kit for review, and I’ve already checked out the hardware and accessories in the first post. I’ve now had time to test the camera, and I’ll explained how to set it up, test some of the key features via the provided guided tour, and show how it’s possible to customize the camera to your needs with one example. Getting Started with JeVois-A33 In theory, you could just get started by inserting the micro SD card provided with […]

Nexell NXC100 Voice Recognition Chip, NXP4330Q Processor, and ALTO Development Board

I wrote about NanoPi Fire2 & Fire3A boards based on Nexell S5P processors a few days ago, and at the time, as I checked out Nexell website, I found out about the company’s NXC100 Voice Recognition SoC that can be used in 4-mic array board. The chip can then be connected through SPI to a host processor, and Nexell appears to have a NXP4330Q Smart Voice kit based on their quad Cortex A9 processor of the same name. But since documentation is really limited, I looked for more details, and came across NXP4330Q based ALTO board design by InSignal, which sold the Exynos powered Arndale boards a few years back. Nexell NXC100 Voice Recognition SoC The chip is the only product from the “A.I related” section of therir website, but more are likely to come out as the company is working on GP-GPU (General Purpose GPU), machine learning, and even registered […]

Google Releases Tensorflow Lite Developer Preview for Android & iOS

Google mentioned TensorFlow Lite at Google I/O 2017 last may, an implementation of TensorFlow open source machine learning library specifically optimized for embedded use cases. The company said support was coming to Android Oreo, but it was not possible to evaluate the solution at the time. The company has now released a developer preview of TensorFlow Lite for mobile and embedded devices with a lightweight cross-platform runtine that runs on Android and iOS for now. TensorFlow Lite supports the Android Neural Networks API to take advantage of Machine Learning accelerators when available, but falls back to CPU execution otherwise. The architecture diagram above shows three components for TensorFlow Lite: TensorFlow Model – A trained TensorFlow model saved on disk. TensorFlow Lite Converter – A program that converts the model to the TensorFlow Lite file format. TensorFlow Lite Model File – A model file format based on FlatBuffers, that has been […]

Intel Speech Enabling Developer Kit Works with Alexa Voice Service, Raspberry Pi 3 Board

We’ve known Intel has been working on Quark S1000 “Sue Creek” processor for voice recognition for several months. S1000 SoC is based on two Tensilica LX6 with HiFi3 DSP, some speech recognition accelerators, and up to 8x microphones interfaces which allows it to perform speech recognition locally. The solution can also be hooked to an application processor via SPI, I2S and USB (optional) when cloud based voice recognition is needed. Intel has recently introduced their Speech Enabling Developer Kit working with Amazon Alexa Voice Service (AVS) featuring a “dual DSP with inference engine” – which must be Quark S1000 – and an 8-mic array. The kit also includes a 40-pin cable to connect to the Raspberry Pi 3 board. Intel only provided basic specifications for the kit: Intel’s dual DSP with inference engine Intel 8-mic circular array High-performance algorithms for acoustic echo cancellation, noise reduction, beamforming and custom wake word […]

JeVois Smart Machine Vision Camera Review – Part 1: Developer / Robotics Kit Unboxing

JeVois-A33 computer vision camera was unveiled at the end of last year through a Kickstarter campaign. Powered by an Allwinner A33 quad core Cortex A7 processor, and a 1.3MP camera sensor, the system could detect motion, track faces and eyes, detect & decode ArUco makers & QR codes, follow lines for autonomous cars, etc.. thanks to JeVois framework. Most rewards from KickStarter shipped in April of this year, so it’s quite possible some of the regular readers of this blog are already familiar the camera. But the developer (Laurent Itti) re-contacted me recently, explaining they add improves the software with Python support, and new features such as the capability of running deep neural networks directly on the processor inside the smart camera. He also wanted to send a review sample, which I received today, but I got a bit more than I expected, so I’ll start the review with an […]

NVIDIA DRIVE PX Pegasus Platform is Designed for Fully Autonomous Vehicles

Many companies are now involved in the quest to develop self-driving cars, and getting there step by step with 6 levels of autonomous driving defined based on info from Wikipedia: Level 0 – Automated system issues warnings but has no vehicle control. Level 1 (”hands on”) – Driver and automated system shares control over the vehicle. Examples include Adaptive Cruise Control (ACC), Parking Assistance, and Lane Keeping Assistance (LKA) Type II. Level 2 (”hands off”) – The automated system takes full control of the vehicle (accelerating, braking, and steering), but the driver is still expected to monitor the driving, and be prepared to immediately intervene at any time. You’ll actually have your hands on the steering wheel, just in case… Level 3 (”eyes off”) – The driver can safely turn their attention away from the driving tasks, e.g. the driver can text or watch a movie. The system may ask […]
