Pas Home - Index Hi last week i made a small proto of temperature sensor case. A little trip to the home contruction store and i buy 24x24 4.5mm acrylic clear board. With some work i made an very fonctionnal and quite aesthetic mounting support....
In this post I will talk a little about GPIOs.There are a lot of libraries that make using of GPIOs really easy.I decided to use the PIGPIO library, available here http://abyz.co.uk/rpi/pigpio The PIGPIO has a lot of featuressampling and ti...
I've started work on a dog GPS prototype, but don't have anything to show yet. The idea is to transmit the dog GPS location to OpenHAB, and have OpenHAB evaluate the coordinates. If the coordinates are outside the yard, then play ...
In last post, we looked how to dweet enocean sensor data from raspberry pi using Enocean-Py library and view it real time in your desktop using 'desk_viewer.py' script. In this post, we'll see how to dweet from enocean data from openHAB and also how ...
First an update on the PCB I mentioned in my last post.The PCB came out really well and was useful in fitting the sensors. Below I have also attached the pictures of the STM330 fitted onto these boards.Here are pictures of the PCB on both sides. In c...
After giving up on the existing REST framework I made some progress on the client side of things. I took my basic example and formed a small Java library out of it.It features:connection to a OpenHAB server by just providing the base addressdiscovery...
A One Wire ActPictured is a 19 year old Dallas 1-Wire Demonstration and Development Kit PCB connected to my Model B Raspberry Pi.That's right!. The 1-Wire Interface is nearly if not 20 years old. The 4/8bit parallel interfaced LCD Character modul...
Introduction I have been working with MQTT for some time now, especially after a demo by Benjamin Kabe of the Eclipse Foundation on Paho, LWM2M and the related. MQTT offers a light communication method for connected devices. In my project, I hav...
Two B or not 2 Bs? Figure 1. A Model B+ next to a Model B. There are some subtle changes including the repositioning of some connectors, the replacement of linear power supplies with switch mode types, the replacement of the SD connector wi...
In this post we will see how the blob detection feature I implemented in one my previous posts can be useful to implement the features I'd like to achieve, namely flames detection A flame is not an efficient means to light your house: it emits m...
