How to Control Your Air Conditioner with Raspberry Pi Board and ANAVI Infrared pHAT

Leon ANAVI may be a full-time software engineer, but in his spare time he has started to develop open source hardware project with the help of others and by himself. Last year, I got hold of his RabbitMax Flex HAT for Raspberry Pi, and tested it with the provided LCD display, one temperature sensor, and a Raspberry Pi 2 board. The board also featured IR receiver & transmitter, and I tried to use it with my aircon remote control, but at the time I did not find a way to do it easily, and control my TV with LIRC instead. Leon has now made a simpler, smaller, and cheaper add-on board for Raspberry Pi Zero, and other Raspberry Pi boards with a 40-pin header, with 3x I2C headers, two IR transmitters, and one IR receiver. He sent me a sample of “ANAVI Infrared pHAT”, and after quickly describing the board, […]

New 96Boards IoT Edition Boards Showcased at Linaro Connect 2017: BlueSky IE and WRTNode IE

Linaro Connect Budapest 2017 is taking place this week in Hungary, and during George Grey – Linaro CEO – keynote, he provided a status updates for the Linaro group, addressed some of Linaro’s criticisms from members and the community, and unveiled two upcoming boards compliant with 96Boards IoT edition both running Zephyr OS, and adding to BLE Carbon board announced last year. The first board is BlueSky IE board with the following key specifications: SoC – RDA Micro RDA5981A ARM Cortex-M4 Wireless MCU with 64KB ROM, and 32KB cache System Memory – 485KB SRAM. It’s unclear if that’s only the on-chip SRAM, and there’s also some external PSRAM added. Storage – 8Mb NOR flash 802.11 b / g / n HT20 / 40 mode Connectivity – 802.11 b/g/n WiFi with support for HT20 / 40 modes Crypto security hardware The second board is WRTnode IE: SoC – Mediatek MT7697 ARM […]

Secure IoT Connectivity with NodeMCU ESP8266 Board, ATECC508A Crypto Chip, Mongoose OS, and AWS IoT

There are many examples of Internet of Things projects, but more often than not the implementation is not secure, either because the device is exposed to the Internet with minimum or no security (worst case), or a gateway (hopefully) provides secure connection to the Internet, but the communication between sensor nodes and the gateway in the local network is not secure, due to memory limitation of the nodes, for example it might be challenging to implement security on ESP8266. Mongoose OS is an open source operating system for the Internet of Things developed by Cesanta working on ESP32, ESP8266, STM32, and TI CC3200, and the developers have demonstrated a secure solution with Mongoose OS running on ESP8266 connecting over a TLS connection to AWS IoT (Amazon Web Service IoT) and using TLS credentials stored in Microchip ATECC508A CryptoAuthentication Device. The addition of ATECC508 chip either using “XplainedPro extension board for […]

Arrow Chameleon96 Board To Feature Intel Altera Cyclone V SE FPGA + ARM SoC in 96Boards Form Factor

Embedded World 2017 will start in about one week, and take place in March 14 – 16 in Nuremberg, Germany, so we can expect interesting embedded news coming soon. Arrow has written a blog post with plans to announce three 96Boards at the event: Meerkat based on NXP i.MX 7Dual, Chameleon96 based on Intel/Altera Cyclone V FPGA + ARM SoC, and Systart Oxalis 96Boards EE board powered by NXP LS1020A single core ARM Cortex A53 SoC. I’ll start with Chameleon (Chameleon96) today, as it’s the first with FPGA fabric, and I could find some technical details and photos about the board. Chameleon96 board specifications: SoC – Intel PSG / Altera Cyclone V SE 5CSEBA6U19I7N with a dual core ARM Cortex A9 processor @ up to 800 MHz and FPGA fabric with 110K Logic Elements Chips, Ports and Features connected to FPGA: Integrated USB-Blaster II JTAG cable Configuration sources: SD Card, […]

$12 AI Light ESP8266 based WiFi RGB Light Bulb Supports MQTT via ESPurna Open Source Firmware

AI-Thinker is famous in the maker world for their ESP8266 modules, but they’ve also recently launched a WiFi RGB light bulb that sells for about $12.5 and up on eBay and Aliexpress. Some people noticed, and bought samples online, including Xose Pérez (aka Tinkerman), ESPurna open-source firmware developer, who could confirm ESP8266 was used in the light bulb, did some investigations, and eventually added the light bulb into ESPurna, which means it can be managed using MQTT or a web interface. AI Light looks very similar to Philips Hue, but comes with WiFi instead of Zigbee. AI Light “M1636” key features: RGBW LED E27 bulb with 16.7M colors Connectivity – 802.11 b/g/n WiFi Encryption – AES Voltage Range – 110-240V LED Power – 5 watts WiFi Power Consumption – ≤0.3W Temperature Range – -5~45degree Humidity – ≤80% Certifications – FCC, CE, ROHS If you’re going to use the stock firmware, […]
