This Project automates the configuration of a Raspberry Pi into a WiFi Access Point using my opensource Github Repo "pi-ap". If you can edit a file with nano and change a few values in a variables file, you  can do this project. Wireless Communications Technology Wireless   SOFTWARE: - My Opensource repo Github repo "pi-ap"   HARDWARE: - Raspberry Pi 3B+ or 4 running Raspbian Stretch or Buster.   ADDITIONAL REQUIREMENTS: - DHCP enabled port in a router or switch to connect th ...
I recently brought the DraStic ds emulator on my phone. I setup the left stick button to switch screens but i have a project idea to fix the second display issue. I wanna use a raspberry pi zero as a display driver to take a usb c input (via usb c dongle if i have to) I was looking for a 16:9 5-6 inch display(oled preferable and at least 1080p) Can you help? Could you even make a video on it so i can follow it? I know using my ds with my official cart of the game is the easy solution, but i love ...
Good day! I've recently built my own portable console, and now I wonder what people think about it. If you have any questions, I will try to answer them as fast as I can.   If you're interested in buying one, you can visit: https://www.etsy.com/listing/682397120/portable-retro-game-console-with-big-79      ...
Introduction This project attaches a large, low-cost 3.5 digit multi-meter style LCD screen to a Pi!   Plain glass liquid crystal displays (with no in-built driver) do not seem to get much love in hobbyist projects, since ready-made modules with built-in driver chips are low cost. Furthermore alphanumeric or graphic LCD modules are a better option most of the time, due to the flexibility in what can be displayed. However, if very low power consumption is needed, then this project could be ...
Introduction For this project I'm going to use a raspberry Pi to create a home irrigation system using node red to provide the user interface.   The build for the control box is covered in my homebrew controller project here: Raspberry Pi Homebrew controller with Node Red UI   So I'm going to use the same controller and use web service to count the number of days without rain in the town that I live.  I'm using the https://openweathermap.org/  site which has a python API ...
Introduction For this project I'm going to upgrade my trusty home-brew temperature controller.   I'm using a fish tank temperature controller at the moment to control a heater belt with a relay which is kind of ok apart from I need to go into the garage to check what it's doing and the temperature sensor which is just a cheap thermistor just gets bungee'd to the outside of the mash tub so I'm not sure how accurate it is, especially since the temperature sensor ends up being close to the ...
In my quest to use a Raspberry Pi 3B+ for creating art, I need to be able to control the GPIO pins. So next step was to look for some information on doing just that.   A quick search of element14 uncovered this blog by shabaz where he illustrates controlling the GPIO lines with Python. That should get me off to a quick start and Python should be ok to work with, at least for the simpler art pieces [I haven't done very much with Python and, to be honest, I didn't entirely like it when ...
I'm going to be using a Raspberry Pi 3 B+ as part of the PiCasso Design Challenge   Here it is, along with some art materials     I haven't used one before and I'm trying to get it going 'headless' (ie through the ethernet cable, without a monitor or keyboard attached). I'm following all the useful advice given to dubbie in these blogs   Getting Started with an Old Raspberry Pi #1 : Its a Model B (not a B+)   Getting Started with an Old Raspberry Pi 1B : Connecti ...
Use a USB air-quality sensor dongle to quickly mount an indoor air monitoring system and prevent headaches and further impact on health.           Things used in this project  1.OhmTech.io uThing::VOC 2.Raspberry Pi 3 Model B   VOCsVolatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consist ...
Achievement of high efficiency, low power loss, and real-time response are major challenges in an automated control process. Control processes are often error-prone due to external factors such as abnormal input power, variable temperature, load, and pressure. In a real-time environment, the process must not oscillate for any external forces. Closed-loop systems are designed to include an error compensator to eliminate the error. The PID (Proportional Integral Derivative) controller developed in ...
Hi all,   We have started with the development of our own embedded MIPI camera module for the Raspberry Pi with an industrial image sensor. Currently, we are in the specification phase and are interested in your preferences. We are planning to develop a product that fits your requirements. Please fill out this short, 4 question poll. It would really help us out.   Thanks. ...

In this tutorial, we will send an event to Wia using Android Things. Components Raspberry Pi (We used a Raspberry Pi 3 Model) PIR Sensor USB Cable Jumper wires You will also need Android Studio and a Wia account. You can download the latest version of Android Studio here. Wia is a cloud platform to support your Internet of Things devices. You can sign up or login here. Getting StartedFirst, we need to install Android Things onto the raspberry pi. Click here to go to the Android Things console ...
  Hi All, For this tutorial, we're going to build a facial recognition camera that can detect if someone is smiling (or not). Here's what you will need: - Raspberry Pi (any model 3, 3+, Zero, etc). - Raspberry Pi Camera Module (we recommend this one). - Micro SD card (we recommend at least 8Gb). - Micro USB to USB cable. We've already got lots of in depth guides showing you how to setup your Raspberry Pi from scratch. You can view those here.   Setup the CameraOnce you've got everythin ...
