Find IP Address via Morse Code

Have you ever connected your Raspberry Pi to a new Ethernet cable but don't have a monitor to see its new IP address? Or maybe you don't want to connect a monitor, keyboard, and mouse to search for the IP address when you don't plan on using any of the three? Morse Code This project will run a Python script on startup that grabs the IP address of your Raspberry Pi and outputs it to a GPIO port through Morse ...

Conexant 2-Mic Hands-Free Alexa on RaspberryPi

Overview This guide provides step-by-step instructions for setting up an Alexa prototype using a Conexant AudioSmart 2-Mic Development Kit for Amazon AVS and a Raspberry Pi. It demonstrates how to access and test AVS using the Conexant development kit, our Java sample app (running on the Raspberry Pi), a Node.js server for authorization (running on the Raspberry Pi), and a third-party wake word engine that ...

Pi to Azure to Alexa

Overview This project is about surfacing information from a Raspberry Pi through an Microsoft Azure infrastructure to an Amazon Alexa Skill. This could be an architecture that would support telemetry data collection over time by automating the collection, transport and storage of data from a Raspberry Pi. Maybe the most obvious example of a system like this would be a weather station that cyclically collect ...

Distributed Brew Controller

History and Problem Statement I have built a custom electric home brew set and have been using it in various stages of completion for about 5 years. I started using the BCS-460. It was cool, but over-kill and not specific enough for brewing. Next, I set up the very cool "Brew Bench" by Andrew Van Tassel and Lee Kendrick - loved the UI; it was super cool idea. As I used it the first time, I realized that I d ...

A/B Testing on the Physical Web – The Beacon

About The Eddystone Beacon Beacons are the heart of the Physical Web. When you set up a beacon you enable users to seamleweb there is no need to install an app, evessly interact with physical objects and locations. With the physical rything happens in the mobile browser. We are going to be building an Eddystone beacon   Eddystone is a protocol specification that defines a Bluetooth low energy (BLE) mes ...

Automated Garden

This is the second project using my automated garden, but this time everything will be controlled by Cayenne so it will be a lot easier. Also I added a Raspberry Pi in order to do a time-lapse video. Setting up the Arduino In order to monitor our garden I used a few devices which can be helpful. Before starting, remember to connect the Ethernet shield to the Arduino. Connections Soil moisture: To check if t ...

Playing with Electronics: RPi GPIO Zero Library Tutorial

Overview A simple way to learn electronics is using Raspberry Pi and its GPIO Zero Library. With a very few lines of code in Python you will be able to control actuators, read sensors, etc. It was created by Ben Nuttall of the Raspberry Pi Foundation, Dave Jones, and other contributors. Here in this quick tutorial, I will give you the basis for creating simple circuits controlled by the Raspberry Pi. For fu ...

Animated Smart Elf with Raspberry Pi Servo Controller

Introduction In this project we show you how to Animate an Elf on a Shelf with the PivotPi, a Raspberry Pi Servo Controller, making it a smart Elf. We’ll attach a small servo to the Elf’s arm to make it wave, we’ll use a distance sensor to see if anyone is close to the Elf on a Shelf, and we will tie it all together with the Raspberry Pi and GrovePi Zero. When someone approaches, the Elf will begin enthusia ...

Roller-shutter Automations in Python

Background All my roller shutters work with electrical motors, so it made sense to hook them up to my z-wave gateway that I had set up in a previous project. This provides me with remote control but also other features like metering (kWh). This is cool and all, but I'm pretty much a lazy guy. If I can avoid having to press a button 2 times a day, then hell, I don't want to press that button anymore. Even if ...
