Giveaway Week Winners – November 2019

We just had another of our yearly “Giveaway week” on CNX Software with 7 prizes including Arm and RISC-V development boards, NB-IoT tracker, USB-C hub, as well as development kits based on ESP32 or ESP8266 WiSoCs. People just had to comment within a 48 hours period, and we would randomly select a winner each day. We now have all confirmed winners with a strong start from Europe, Asia catching up mid-week, before with Poland and Brazil taking the week-end prizes: Balena Fin Developer Kit – Laurent H, FRANCE WisCellular NB-IoT & eMTC GPS Tracker – Jimmy, SWEDEN MINIX NEO S1 USB-C Hub with 120GB built-in SSD – Jeroen, BELGIUM Maixduino Sipeed M1 RISC-V AI Kit – Nguyen Tung, VIETNAM ANAVI Gas Detector Starter Kit – Bumsik Kim, SOUTH KOREA Particle Mesh IoT Development Kit – Wojciech Lubicz-Lapinski, POLAND NanoPi M4V2 SBC & Metal Case Kit – Thiago Tavares, BRAZIL I […]

Mastak Modular Air Quality Monitor Kit Supports CO2, Dust, Formaldehyde, Ozone and other Sensor Modules

The Mastak Indoor Air Quality Monitor Kit Medium Systems Limited, a UK company has released the Mastak, SoMs designed in a mechanical range that allows for indoor air quality monitoring, with a data IoT cloud service, and communications that include NB-IoT, 5G, WiFi, BLE, and LTE-M.  The system is a new addition to the air monitoring market place. There have been reports on other air quality monitors in past articles that covered quick start and user experience with Sonoff SC WiFi, vThings WiFi CO2 Monitor, and the ANAVI Gas Detector. The Specs The ecological modules are all compatible and contain processor, peripherals and the sensors for data monitoring and collection, as well as the necessary power electronics. The modules were designed too and allow the user to arrange the systems into custom arrangements and place in unique form factors. There are a number of options also, for even further expandability […]

PT100 Resistance Temperature Detector (RTD) Probes Support Extreme Temperature Ranges

I’ve been playing with temperature measurements in several hardware platforms such as Texas Instruments eZ430-Chronos Watch, Sonoff SC environmental monitor, Wemos D1 board with aDHT21 temperature sensor, or more recently ANAVI Thermometer with the last three platforms based on ESP8266 WiSoC. All four devices/boards above have temperature sensors designed to measure ambient temperature with for example DHT22 having a range of -40 to +125 degrees Celsius.  I had also come across DS18B20 waterproof temperature probe to measure liquid temperature several times with a range of  -55 to 125°C. Good for most use cases, and for example you could check boiling water with the later. But I had never really thought about measuring data for much lower or much higher temperatures, and this morning I came across two “PT100” temperature probes on IC Station new arrivals feed namely WZP-187 ($4.89) and an unnamed probe ($3.42) respectively capable of -200°C to +400°C […]

Embedded Linux Conference & Open Source Summit 2019 Schedule

In the last few years, I covered the Embedded Linux Conference and IoT Summit schedules since both were happening at the same time and in the same location. But the Linux Foundation have recently announced the Embedded Linux Conference will combine with the Open Source Summit, so the IoT Summit appears to have been phased out. The full schedule for the events taking place on August 21 – 23, 2019 at the Hilton San Diego Bayfront, USA, has also been released, so I’ll create a virtual schedule with some of the sessions most relevant to this blog. Wednesday August 21, 2019 11:30 – 12:05 – What’s New with U-Boot? by Simon Glass, Google LLC U-Boot is a widely used bootloader in embedded systems. Many users are unaware of the wide feature-set of U-Boot, particularly features added in the last few years. This talk aims to bring users (and prospective users) […]

Self-powered Swallowable Thermometer Measures Internal Body Temperature

Having just written about a thermometer board for home automation,  I’ll stay on the temperature measurement topic, as I’ve found another thermometer that targets the medical field instead. Body temperature measurement at my local hospital is done under the armpit, which does the job in most cases, but more accurate temperature measurement of “deep body temperature” is normally achieved through rectal temperature measurement which is not as practical and comfortable for most people. Daily measurements of deep body temperature can apparently allow physicians to better understand “biological clocks”. In practical terms, it means doctors would be able to know ovulation cycles, measure the fatigue degrees of athletes, and even prevent heat strokes and hypothermia. Seeing the impractically in the conventional method, Nakamura Lab at Tohoku University developed a “swallowable thermometer” for this purpose. The swallowable sensor measures just 9.16mm in diameter, is allegedly perfectly safe to the human body, and […]

FOSDEM 2019 Open Source Developers Meeting Schedule

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where developers meet on the first week-end of February to discuss open source software & hardware projects. FOSDEM 2019 will take place on February 2 & 3, and the schedule has already been published with 671 speakers scheduled to speak in 711 events themselves sorted in 62 tracks. Like every year, I’ll create a virtual schedule based on some of the sessions most relevant to this blog in tracks such as  open hardware, open media, RISC-V, and hardware enablement tracks. February 2 10:30 – 10:55 – VkRunner: a Vulkan shader test tool by Neil Roberts A presentation of VkRunner which is a tool to help test the compiler in your Vulkan driver using simple high-level scripts. Perhaps the largest part of developing a modern graphics driver revolves around getting the compiler to […]
