Create an Azure IoT Hub Stream Processor with Dapr

💡Check Out all Dapr Posts Creating a stream processor is always an interesting task, you want to be able to take incoming message and process them one by one, executing some actions along the way. Typically, we would use Apache Spark or Apache Flink to process these incoming streams, but

Creating an Azure IoT Edge Golden Image

So you are working on a production scale and suddenly notice that you don't have to provision just 1, not 10 but 1000s of devices. What do you do? This is where you start automating stuff, rather than doing everything manually, you ideally: 1. Create an image 2. Flash an

Automatically Provision an IoT Device with DPS

Once you get further in the world of the Internet of Things (IoT) you will notice that you have to setup devices in bulk rather than device-per-device. This is where Azure helps you through a service named Device Provisioning Service. Requirements * Azure IoT Hub (Standard Tier or higher) * A device

Azure IoT Edge Troubleshooting

Working with Azure IoT Edge might be difficult sometimes seeing some of the errors that are not that easy to understand. That's why I want to provide this dedicated post with Troubleshooting tips in case you get problems. If you ever find yourself stuck, comment below so I can help

Running Dapr on Azure IoT Edge

I've been working on a large-scale project that has some interesting requirements performance wise. While having around 6+ modules, I should get a performance of around 10ms roundtrip! One container does AI inferencing within ~2ms. Problem Definition The problem I am seeing now is that the Azure IoT Edge SDK

Setting up Stable Baselines with Python 3.7 and WSL 2

I've been playing around a bit with Stable Baselines lately for an upcoming project. However while playing, I encountered some issues seeing that Stable Baselines currently requires Tensorflow <= 1.14 which is only supported through Python < 3.8. Due those difficulties, I thought it would be interesting to share how

Autonomously Landing a Lunar Lander with an Xbox Controller Robotic Arm - Part 2

In Part 1 I explained you how you can create a Robot Arm that can be mounted on an Xbox controller. In OpenAI Lunar Lander I then continued to see how we are able to train a lunar lander environment to land a lunar lander all by itself with a

Training the Continuous Lunar Lander with Reinforcement Learning, RLLib and PPO

For an upcoming blog post, I would like to have a robotic arm to land a Lunar Lander autonomously. In Part 1 I explained how we can build such a robotic arm already, but now we need to be able to go deeper into how we are able to train

Autonomously Landing a Lunar Lander with an Xbox Controller Robotic Arm - Part 1

Creating an Xbox Robot Arm is something that I've been wanting to do ever since I saw the post by Kevin Drouglazet who was able to utilize an Xbox Controller with an arm he created and was so friendly to publish the design files for (I am definitely not a

Digital Twins - Creating an Open-Source Platform

In a previous blog post I introduced the concept of creating a Digital Twin representation utilizing Dapr's Virtual Actors. Now, this was a theoretical post on how feasible this could be. Of course anything theoretical should also be put in practice, which is what I have been doing this weekend
