Do you like gardening but can’t find the time to maintain it? Perhaps you have some houseplants that are looking a little thirsty or looking for a way to automate your hydroponics? In this project we will solve those problems and learn the basics of MudPi by building an automated garden system to help…
This is my the first mechanical keyboard project. And this will be for daily usage. Although the possibilities are almost endless, I limit myself to the basic functionality: An ergonomic keyboard with mouse functions. While searching for parts I came across a new type of switch. A low-profile version of the Cherry MX…
The Raspberry Pi provides an interesting environment for machine learning. It has a relatively powerful CPU & GPU, is lowcost, supports many of the Linux packages/drivers, and can still be used as a microcontroller to interface with a myriad of different sensors, motors, and other peripherals. Because of this, we have the ability to…
Building our centralized web-controlled home video surveillance system. Last episode In the previous posts, dedicated to the creation of a video surveillance system based on Raspberry Pi and the MotionEye application, we saw how to install the software necessary for our architecture and how to configure a first video camera connected via USB and…
Hi Makers! A while back I got Raspberry Pi, but I didn’t really know what to do with it. Recently, Minecraft has come back into popularity, so I decided to set up a Minecraft server for me and my friends to enjoy. Well, it turned out to just be me : /. Anyway, now…
https://youtu.be/kgY40e9mi8w The Cassette Pi is a self-contained real-time notification scroller, all housed neatly inside a transparent cassette tape. A Raspberry Pi Zero is sandwiched between the two tape reels, retrieving all manner of Internet of Things notifications from the fabulous IFTTT (If This, Then That) service, delivered almost instantly to the Pi via an Adafruit.IO feed and a…
Quick-reference (QR) codes are similar to barcodes, as they are able to encode data that is represented by black and white squares. But instead of using a laser, a camera differentiates between the spaces and then sends that information to be processed. They are comprised of several large squares that help to align and position…
Building our centralized web-controlled home video surveillance system. Second episode. In the first episode of this series, dedicated to the creation of a video surveillance system, based on Raspberry Pi and the MotionEye application, we saw how to install the software necessary for our architecture and how to configure a first video camera connected…
So this article is going to be my notes on how I built one using a cheap GPS module off eBay as the reference time source and a Raspberry Pi. (a 2B in this case, but hopefully the differences for newer models will be minor; if there are any, they’re probably around the behavior…
In this tutorial, you will learn how to set up a Raspberry Pi with Codesys to act as both a PLC and an EtherCAT master. It will be used to control the on-board LED found on the EtherCAT Arduino Shield by Esmacat (EASE) Slave device that is attached to an Arduino Uno. First, some general…
https://youtu.be/kSxJwWPEe6g This is a doorbell with smart functions. It does sound like a regular doorbell when you press the button, but it also starts a livestream and sends a message via WebHook on Slack. We made this as a project for our embedded class. More info
