AXIOM Beta USB 3.0 plugin module
If you've been following the project you'll know that, where recording data is concerned, the AXIOM Beta has relied solely on external, off-the-shelf, HDMI recorders and all the pros and cons that are known to be inherent with those devices up to now. With the USB 3.0 plugin module, however, any computer with USB 3.0 connectivity can be used as an AXIOM Recorder. This will allow us to define format/container/metadata/etc. of uncompressed raw 4k footage for the first time. The software for this is in development and first tests have showed the data exchange between...
New book on how to made a complete ready-to-sell home automated system with ESP8266
I've been busy in the latest months writing a book to cover some key aspects of the ESP8266 ecosystem, the chip, the cloud and a mobile application.
The book will teach you and will give you a ready-to-sell solution for an IoT product.
You will discover how to work with the GPIOs on the ESP8266, how to build your basic thermostat for your house, how to control it from your mobile with your own cloud system based on MQTT.
Securing the data using authentication at the broker level and SSL is explained in a special chapter.
Real-time communication has a dedicated chapter where you...
BME280 and ESP8266
Latest environmental sensor from Bosh is the BME280 which can measure:
temperature
humidity
pressure
and can be found in mobile phones (Nexus 5). There are rumors that the BMP280 is a BME280 which couldn't be calibrated for humidity, but I have no confirmation on this.
BME280
Can be used for:
Indoor navigation (based on changing the measured altitude - pressure)
Outdoor navigation
Weather forecast
Home application control
Context awareness ( change room detection)
Internet of Things.
Temperature precision is ± 1 C degree in 0-60C range.
Can be found in multiple modules, from SPI connectivity to I2C.
Make sure that if you are using the I2C version to change the I2C address to 0x76. ( Default...

www.apertus.org: One week with the AXIOM Team
https://www.youtube-nocookie.com/embed/cdbENj-ml_4
Last week, apertus° community member davidak, from Germany, visited Vienna and participated in a number of AXIOM related activities in the course of one week ranging from hardware assembly, software development and building ergonomic enclosure evaluation prototypes, to shooting with the AXIOM Beta.
Davidak on various AXIOM duties in Vienna.
Shooting the Signs of Autumn in a Vienna Park
Of course, nobody wants to work on the AXIOM project without taking the camera for a spin, and so, even though the weather wasn't great (typically autumn), we did. There was only one development prototype at hand but we made the most of it!...
Getting air quality with ESP8266 and Amazon Alexa
https://i.ytimg.com/vi/WvbpKBgGWjM/0.jpg
If last week I've managed to get the temperature and humidity with ESP8266 and Alexa, now it's time to integrate the air quality sensor GP2Y1010AU0F from Sharp.
The GP2Y1010AU0F it is a compact optical dust sensor that has an infrared emitting diode and a phototransistor that are diagonally arranged. It detects in fact the reflected light of the present dust in the air. It is effective to detect very fine particle like cigarette smoke and it can distinguish from the house smoke from the house dust.
GP2Y1010AU0F sensor.
It has 6 pins and the electronic inside is split in two parts, the IRED emitting part and...
Getting temperature from ESP8266 over MQTT with Amazon Alexa
https://i.ytimg.com/vi/QQ5jtqvm_HQ/0.jpg
With the help of the Iotcentral.eu platform now I can get room temperature or outside temperature with just an ESP8266 and a temperature sensor like DHT22 or DS18B20 or BMP280.
The Alexa is questioning the iotcentral.eu server that will ask my local broker that will publish a message the the ESP8266 to ask the temperature for my room. The values for temperature and humidity will travel the other way around to Alexa, that is so nice and is letting me know about them.
On Iotcentral.eu you will find also a demoapp ( source code on git) for a plug, but you can...
On the Linux Kernel Enforcement Statement
I'm late with covering this here, but work overload is having its toll on my ability to blog.
On October 16th, key Linux Kernel developers have released and anounced the Linux Kernel Community Enforcement Statemnt.
In its actual text, those key kernel developers cover
compliance with the reciprocal sharing obligations of GPLv2 is critical and mandatory
acknowledgement to the right to enforce
expression of interest to ensure that enforcement actions are conducted in a manner beneficial to the larger community
a method to provide reinstatement of rights after ceasing a license violation (see below)
that legal action is a last resort
that after resolving any non-compliance, the formerly incompliant user is...
SFLC sues SFC over trademark infringement
As the Software Freedom Conservancy (SFC) has publicly disclosed on their website, it appears that Software Freedom Law Center (SFLC) has filed for a trademark infringement lawsuit against SFC.
SFLC has launched SFC in 2006, and SFLC has helped and endorsed SFC in the past.
This lawsuit is hard to believe. What has this community come to, if its various members - who used all to be respected equally - start filing law suits against each other?
It's of course not known what kind of negotiations might have happened out-of-court before an actual lawsuit has been filed. Nevertheless, one would have hoped that people are able to talk to...
