ANAVI Gas Detector is an ESP8266 based board designed for MQ gas sensors supported by Arduino. This allows you to easily monitor air quality, or more accurately air conductivity using MQ-135 sensor as part of the starter kit either visually on the OLED display, or through your smartphone or computer using MQTT via automation platform such as Home Assistant. Leon Anavi sent me an ANAVI Gas Detector Starter Kit to have a look, and I’ll report my experience with the kit using it standalone, and through Home Assistant. Starter Kit Unboxing The kit contains the open-source hardware, ESP8266 based ANAVI Gas Detector board, a plastic stand, an OLED display, a USB to serial adapter, a gas sensor, and a few KiCad and ANAVI stickers. The board itself comes with an ESP8266MOD module, features a micro USB port for power, a reset button, four LEDs, a UART console, a 4-pin GPIO […]
ESP32-MeshKit is a Development Kit for ESP32 Mesh Networking
The ESP8266 was a jewel in its peak, it ruled the maker’s world in the need for creating a low-cost WiFi module. Being Arduino compatible also furthered its glory then the ESP32 came in. ESP32 offered so much more than the ESP8266, and most importantly it was also affordable. With support for Bluetooth and WiFi, ESP32 was to open a new frontier for the development of Internet of Things applications. A major drawback of the affordable ESP32 was the lack of official support of mesh network for the chip, something that was easily possible with the ESP8266. Mesh network allows you to build a network of nodes that can communicate with each other, self heal, and many more possibilities. But thankfully, back in 2018, Espressif Systems released the ESP Mesh Development Framework (ESP-MDF) which sits on top of the IoT Development Framework (ESP-IDF), the official development framework for the chip.

Philips Crowdfunds PicoPix Max Android Pico Projector with Autofocus
PicoPix Extra Connectivity The latest entrant into the miniprojector market is the Phillips PicoPix Max Pico Projector in two versions, x10 and x100, a very versatile projector with many features and large aspirations. The mini projector is nothing new and we have reported on it in depth for units that came out some time ago such as the Rikomagic RKM R1 or Doogee Smart Cube P1. The fact that a major electronics manufacturer is launching a mini projector through a crowdfunding campaign is somewhat unusual, but let’s have a look at the details. Portable Native Full HD Phillips is calling the PicoPix Max Pro a premium, portable cinematic experience. The unit is made to go anywhere and not need a phone or laptop to function but has a large number of ports and options for each port. The LED light bulb is said to last 30K hours, and the source […]
Qt for MCUs – Qt Announces support for Microcontrollers
[Update August 24, 2019: Added information about expected release date and license] About Qt for MCUs Qt- The well known opensource toolkit for creating graphical interface announced their new release: Qt for MCUs, targeting MCU’s. The new graphical toolkit will be capable of running on devices without operating system. This may be a game changer in the entire MCU world, since Qt for MCUs allows developers to create fluid user interfaces on cost-effective micro controllers. This means we will be able to see smartphone like GUI’s which are running on low-end MCU’s with limited resources. With reference to their press release, assuring that Qt-GUI will consume less power to save the battery life. Qt for MCUs Software Stack While developing any applications for MCU, developers still can use their powerful declarative UI language QML and rich set of ready-made Qt Quick controls. And the C++ APIs, helps the user interface […]
Gemini Dual Screen Laptop is Made of Two Kay Lake-R Tablets (Crowdfunding)
[Update August 24, 2019: CNX Software has received a message claiming the project is a scam (identity theft): This is Li Yunjian, the Owner of following company : GST Communication Co., Ltd (Hongkong) 深圳市杰仕特通讯有限公司 (China Mainland) Our Website on Alibaba: https://chinagstgroup.en.alibaba.com/ This is a fraudster illegally using our company information to scam ] [Update October 2, 2019: Gemini Dual Screen Laptop crowdfunding campaign is up again, but references to “GST Communication” are gone] Note by CNXSoft: The campaign is under review and they have stopped taking contributions. I can only assume it’s a trademark issue because Intel did not like them to use the name “Gemini”. If it’s indeed the case, It should be resolved with a new name. We’ll remove this notice when/if the campaign comes back online. The Chinese company GST has been running a crowdfunding campaign for the Gemini, a dual-screen laptop, with the ability to be […]
Getting Started with Sipeed M1 based Maixduino Board & Grove AI HAT for Raspberry Pi
Last year we discovered Kendryte K210 processor with a RISC-V core and featuring AI accelerators for machine vision and machine hearing. Soon after, Sipeed M1 module was launched with the processor for aroud $10. Then this year we started to get more convenient development board featuring Sipeed M1 module such as Maixduino or Grove AI Hat. Seeed Studio sent me the last two boards for review. So I’ll start by showing the items I received, before showing how to get started with MicroPython and Arduino code. Note that I’ll be using Ubuntu 18.04, but development in Windows is also possible. Unboxing I received two packages with a Maixduino kit, and the other “Grove AI HAT for Edge Computing”. Grove AI HAT for Edge Computing Let’s start with the second. The board is a Raspberry Pi HAT with Sipeed M1 module, a 40-pin Raspberry Pi header, 6 grove connectors, as well […]
Pitaya Go is an IoT development board with multi-protocol wireless connectivity
One of the challenges in starting a new IoT project is the question of what connectivity to use. Depending on the nature of a project, there are several wired and wireless connectivity options that can be used to power a project and ensure it’s a success. We have WiFi, Bluetooth, Zigbee, Zwave, LoRa, ZigFox, Thread, NB-IoT, 3G/4G, and others. You can use from anyone, but which one to use is another thing because most development board only support 1 or 2 of those. Well, with the introduction of the Pitaya Go, you don’t have to worry so much about that decision. The Pitaya Go is an IoT development platform with multiprotocol wireless connectivity built-in. The Pitaya Go is based on the Nordic’s high-end multiprotocol SoC nRF52840 and the Microchip’s extremely low power Wi-Fi network controller ATWINC1500B. The nRF52840 SoC is the most advanced member of the nRF52 Series SoC family, and it […]
Socionext 24 GHz Radar Sensor for IoT Measures Distance and Angle (Video)
Last year, we wrote about Socionext MN87900 24 GHz radio wave radar module for IoT with Rx & Tx antennas and a crytal unit that measured just 12×7 mm. The module is made for IoT equipments, security systems, smart home appliances, autonomous vehicles and drones, medical devices, and more. Basically any application that requires distance measurement up to 8 meters (expandable to 30 meters with a radome horn), rough location, or motion detection may leverage the technology. The company has now uploaded a video showing a demo of their 24 GHz radar sensor. Socionext did not explain which exact solution they used, and it’s probably not the full module above, but either one of their sensors based on the link provided in the video description: SC1232AR3 – All-in-one RADAR sensor for Entry Motion & Distance Detection SC1233AR3 – All-in-one RADAR sensor for Entry Motion & 2D Detection I suspect SC1232AR3 […]
