Raspberry Pi Web Server using Flask to Control GPIOs

Rpi_server

In this article “Rui Santos” shows us how to configure Raspberry Pi as server and use it to toggle two LEDs over the internet.

In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs. You can replace those LEDs with any output (like a relay or a transistor). In order to create the web server you will be using a Python microframework called Flask.

This board will let you add WiFi functionality to your Raspberry Pi Zero without having to sacrifice the only available high speed USB port. The board is based on ESP8266 Wifi module.

WiFi on a Raspberry Pi using the HAT connector and an ESP8266. The goal of this project is to add WiFi to the Raspberry Pi Zero while keeping the USB port free for devices or OTG connection to another host.

PiDrive – 314GB hard disk for the Raspberry Pi

20160404121510_2016-04-04---Pi-drive

Western Digital have launched the WD PiDrive, a hard disk specially designed for the Raspberry Pi with a storage space of 314 GB. The engineers have modified the magnetic recording system and electronics to suit the characteristics of the RPi, and reduced the current consumption.

The recommended retail price is $ 45,81 but a discount is available.

How to Control a Reflow Oven with Raspberry Pi

NewImage-49

Here is a great Raspberry Pi based Reflow oven controller from “apollo-ng” on GitHub. You can edit your temperature curve on your browser and Rasberry Pi controls the solid state relays and fan.

Turns a Raspberry Pi into a cheap, universal & web-enabled Reflow Oven Controller. Of course, since it is basically just a robot sensing temperature and controlling environmental agitators (heating/cooling) you can use it as inspiration / basis when you’re in need of a PID based temperature controller for your project. Don’t forget to share and drop a link, when you do.

LiFePO4wered/Pi – LiFePO4 battery for Raspberry Pi

4853551455579281898

Patrick Van Oosterwijck has published a LiFePO4 battery solution for Raspberry Pi that will also act as UPS power supply:

The project is built on top of a LiFePO4wered/USB module. A small board is added with an MSP430G2131 microcontroller that takes care of monitoring input and output voltage, monitoring a PCB touch button, driving a power indicator LED and switching the load (the Raspberry Pi power). The microcontroller is also connected to the Pi’s I2C bus and monitors the Pi’s running state. The small board connects to 8 of the Pi’s GPIO pins but leaves the rest free to allow prototyping using fly leads.

External antenna modifications for the Raspberry Pi 3

Top_3.preview

In this post dorkbotpdx.org show us a couple of different ways that an external antenna can be added to the Raspberry Pi 3.

It’s not clear why an external antenna is not an option for the Pi 3, there are a number of possible reasons and I don’t presume to know the Raspberry Pi Foundation’s exact rationale. It could be to improve the out-of-box experience, an integrated antenna “just works” and there’s no potential for the antenna connector to be broken plugging in an antenna. It could be to reduce complexity, the unit with an integrated antenna is compact and self-contained.

Raspberry Pi 2 Web Hosting – Full Email Server & Web Server

LDSrelience shared this video on Youtube!

This is a short video going over a project I just finished to prove that a Raspberry Pi 2 Model B (new as of February 2015) can run a light duty website and low volume email server. I have installed Apache2 for the web server, which takes like 2 minutes for the basic install, and Postfix and Dovecot for the email server. The mail server definitely takes longer to set up but with the detailed, step by step instructions available at the link below it is really easy to do.

How to Set Up a Raspberry Pi FTP Server

NewImage-169

This tutorial will guide you through the process of installing an FTP server on Raspberry Pi. Check it out:

For uploading files on a Raspberry Pi you should install a FTP server. Such a server is very useful if you use your Pi as a web server or even if you want to have a network storage, which can also be accessed outside of your network if an DNS server is installed.

However this tutorial is not only for web server but can also be used for easy file transfer between Raspberry Pi and your PC.

Raspberry Pi Clever airplane tracker

flyover-nighttime

Jeremy B. Merrill lives near the LaGuardia airport and a lot of planes fly over his house all day long, so he decided to build a LED display showing the departure airport of the airplane that’s flying overhead. For that reason he used a Raspberry Pi, a Software-Defined Radio antenna and open source software that collects and decodes special airplane data, such as location, altitude, registration number etc.

Passenger jets reportedly collect one terabyte of data about themselves per flight. Of that terabyte, most airliners broadcast a tiny portion, unecrypted, over the air, via radio systems called ADS-B and Mode S. Every few seconds, they announce their location, altitude, registration number and – usually – the flight number.

Dump1090 is a program that listens to those broadcasts. Its web interface shows each plane’s precise location and path. I can pick up just about any plane within line of sight of my north-facing window in Prospect Heights. I can “see” planes well into Connecticut or Rockland County, but if the plane shows up even over Prospect Park, I often can’t detect it.
