🤖 Raspberry Pi Zero 3D Printed Video Streaming Robot
ZeroBot is a Raspberry Pi Zero W based robot. It can be controlled using any computer or smartphone via a web browser. The integrated camera module makes for a low latency video stream. In addition the Raspberry Pi acts as a Wi-Fi access point, so no router is required. The parts for the hull as well as the wheels can easily be printed on any regular 3D printer.
Some of the key features are:
▫️ Compact CAD design with 3D printed components
▫️ Analog control via a joystick (and multitouch)
▫️ Simple battery solution using only a standard power bank
▫️ Low latency streaming (~0.2s)
▫️ Easy and cheap to build using widely available components

🤖 3D Printed ESP32 Powered Video Streaming Robot
The ESP32 WiFi robot is a shrunken-down version of the ZeroBot. Instead of a Raspberry Pi, it is powered by the similarly popular ESP32. Despite its lower processing power, the ESP32 robot has a ton of features. It streams color video over WiFi, runs on a small LiPo battery and can be controlled accurately from any web browser. With the 4€ Esp32 and a 3€ camera, it's also really cheap.
Features:
▫️ Fully 3D printed chassis,(almost) no glue needed
▫️ Analog controls using a websocket interface
▫️ Low latency streaming (~100ms) at 120x160px
▫️ Custom PCB, no more messy wiring
▫️ Works with any 3.7V LiPo battery
▫️ Micro USB for programming and charging

🎛 ESP32 OTA (Over-the-Air) Updates
In this guide, you’ll learn how to do over-the-air (OTA) updates to your ESP32 boards using the AsyncElegantOTA library. This library creates a web server that allows you to upload new firmware (a new sketch) to your board without the need to make a serial connection between the ESP32 and your computer.
Additionally, with this library, you can also upload new files to the ESP32 filesystem (SPIFFS). The library is very easy to use, and it’s compatible with the ESPAsyncWebServer library that we often use to build web server projects.

📟 Build an MQTT Intercom with Wio Terminal
In today’s article, we are going to build an Arduino wireless intercom with our Wio Terminal! This project sets up your Wio Terminal as a desk clock, but also allows you to send and receive messages to other devices via the MQTT protocol.
In summary, we will want to achieve three things on our Wio Terminal in this project:
▫️ Display the date and time in realtime
▫️ Be able to receive / send messages over Wi-Fi
▫️ Build a GUI for user navigation

📟 How To Get Wi-Fi (Internet) on Raspberry Pi Pico
We created this tutorial that shows how to get your Raspberry Pi Pico online.
To get Wi-Fi on Raspberry Pi Pico, you will need:
▫️ A Raspberry Pi Pico
▫️ Adafruit Airlift Wi-Fi Featherwing Co-Processor
▫️ 8 x Male to Male jumper wires
▫️ Breadboard
The goal of this tutorial is to get our Raspberry Pi Pico connected to the Internet via Wi-Fi, to access the OpenWeather service API and get the weather for our chosen location.
This raw data is sent to the Python shell, but it could be easily sent to an OLED screen, LCD or used to trigger a sequence of events to occur.

🚰 Arduino controlled smart irrigation system
There are plenty of projects out there that automate irrigation. Many focus on the problem of automatically reacting to dry soil by opening a single valve, but a fully automated system with one valve is not what I want for my lawn. I do not want the sprinklers to turn on unexpectedly and I had to solve a different type of problem: Managing a specific irrigation program with individual control over each sprinkler.
The brains in this case is an Arduino Nano 33 IoT, which is the first time I used one of these. In principle, you should be able to use pretty much any microcontroller, but if you want to control it via Wi-Fi, you quite obviously need one with Wi-Fi capabilities. If you want to run my code with only minor modifications, you probably also want to go for the Arduino, but if you do not mind some adaptation, an ESP32 would probably be the cheaper and much more common choice.

🔫 Wi-Fi Drone Disabler with Raspberry Pi
Build a Pi-powered drone disabler to understand the security risks of wireless communications
Quadcopters capable of transmitting high-quality video are making it possible to affordably record unique perspectives. But these “unmanned aircraft systems,” as the FAA calls them, have posed new challenges in security, safety, and privacy, and many experts caution pilots to consider the implications of increased drone usage. In addition to the concern of constant surveillance, there’s the possibility that businesses (or hackers) can collect location information from mobile devices by using roving drones.
As a result, a cottage industry is forming for anti-drone technology. These devices come in a range of sizes, from plane-mounted to handheld tools. I will show you how to build our own rig to execute a particular network-based attack against one type of quadcopter control: Wi-Fi.
