In this post, we’ll explore how to activate or deactivate a surveillance camera via a Cisco router using Power over Ethernet (PoE) functionality. I’ve implemented a DIY surveillance installation at home using a PoE camera connected to a Cisco Small Business router. Specifically, I’m using the Cisco Smart Switch SG250-10P, which offers robust PoE capabilities that allow you to control power delivery to connected devices. This approach is particularly useful for security purposes, as it allows you to remotely control when your surveillance camera is active without physically accessing the device. ...

When we develop a BPMN process we have to handle correctly Error. An Error can be raised by any component during the processus instance and specially into a Work Item Handler node. This kind of node in jBPM is a Java component implementing the WorkItemHandler interface. Usually in Java program we manage error via Exception mechanism. How to manage Exception inside jBPM WorkItemHandler custom component. To illustrate how to use Exception/Error I propose to create a sample error process. This example will demonstrate how jBPM can transform Java exceptions into BPMN errors, allowing for proper error handling within your business processes. ...

This month I went to Greece for a customer of mine. I worked at Athens on Camel integration with Mainframe legacy systems. The customer wanted to use XML message format throughout the entire Camel route process. Their primary goal was to reuse some Camel routes as new service components, allowing for greater flexibility and modularity in their integration architecture. Fortunately, the Camel framework meets all of these requirements out of the box. In this article, we’ll explore a simple example demonstrating how to implement this approach effectively. ...

If you don’t have yet a RaspberryPi (B+, 2 or zero) device you can use my previous post. ...

Rhiot project has recently decided to primarily support the Kura Eclipse Platform. Our project provides code and extensions for Kura, such as Camel integration and many other features. We’ve developed new Camel components specifically dedicated to the Kura Platform (gpio, cloud, wifi). We chose this platform because it’s an OSGi compliant software focused on the IoT universe, supported by the Eclipse Foundation and Eurotech. While Kura runs natively on RaspberryPi hardware, if you don’t have a RaspberryPi device yet, this tutorial will show you how to run Kura within a Docker container. ...

For a while, I have been developing during my free time for the Rhiot project with my Red Hat colleague Henryk. We started by developing several Camel components such as kura, pi4j, and bluetooth with other volunteers. Now we are focusing on developing and integrating these components for the Kura Platform. Kura is an OSGi Platform designed specifically for IoT, capable of running on RaspberryPi, BeagleBone, or Intel Edison devices. The Kura Platform comes with many embedded services tailored for IoT contexts, including GPIO, USB, I2C, Cloud Service, and more. In this post, we will explore: ...

Recently, I bought the new official Sense-HAT from RaspberryPi foundation. This HAT (Hardware Attached on Top) add-on for the RaspberryPi device includes lots of cool features and sensors. The Sense-HAT comes with an 8x8 RGB565 pixel display, a Joystick, a Gyroscope, Accelerometer, Magnetometer, Temperature, Barometric pressure and Humidity sensors. All sensors are i2c compliant, making them easily accessible with the rhiot camel-pi4j component. This makes it very straightforward to retrieve data from all sensors and transmit them to external systems. The Rhiot team has also developed the first implementation of the rhiot camel-framebuffer component, which now enables pushing images directly to the 8x8 pixel screen. Note that the matrix consists of 8x8 RGB565 LEDs (2 bytes per pixel), providing a colorful display despite its small size. ...
