Hello        For my project I need to have a microphone for giving voice commands and detecting sounds. Because RaspberryPi board don't have a microphone input, I used for this task an external USB sound card adapter, Konig 3D Sound, based on C-Media CM108 Audio Controller. I also add a small audio amplifier and speaker for music and audio feedback.      USB sound card is connected to RaspberryPi through an USB Hub which act also as power distributi ...
Hello        After playing a little with Adafruit MQTT python client and feeds, I decided to change the data transmission protocol between nodes, from HTTP requests to MQTT, RaspberryPi acting as broker+client and ESP8266 nodes being clients.        Looks like Mosquitto is  a very popular MQTT broker among RaspberryPi users (and not only), installation on RPi side is pretty straightforward, since Mosquitto is included in Raspbian Jessie re ...
Hello   In this post I'll show you some more details on wireless nodes schematics and operation and also the code I write so far for nodes and Raspberry web server.   Wireless ESP8266 nodes   At this moment I have two wireless nodes based on ESP8266-201 and built on perf board, which read ambient temperature and send the readings to a server running on RaspberryPi3. From previous hardware build, I changed the Pololu adjustable power regulator with a LM3940 3.3V power regulator ...
     First step in implementing the home automation system is the monitoring part. This part consist in remote wireless nodes which send temperature and humidity measurements values to a central node made with RaspberryPi, where this values are recorded and processed.        These nodes will be built around ESP8266 wireless modules and can be configured to be sensors, actuators or both. On first phase, each node will have its role set from firmware l ...
The "Pi IOT Design Challenge - Smarter Spaces with Raspberry Pi 3" it is a very interesting challenge and I want to present my idea about a possible implementation.        Home automation is aimed to improve life quality in a living space by automating environment control (temperature, humidity, ventilation, air quality, etc.), security and operation of various appliances. But it is hard and sometimes not easy/practical to automate all aspects of a living/working space. ...
