Raspberry Pi Chromium

The information below will help you setup a Raspberry Pi 2 or 3 to automatically load a predefined webpage in Chromium from boot with no user interaction.

Why:

Instead of using a costly full blown MS Windows desktop PC we can use a Raspberry Pi that not only costs hundreds of pounds less to buy but also consumes a minor percentage of power that a full desktop uses as well as being small enough to attach to the rear of the display device.

Raspberry Pi Base Image

Here is a quick instruction set on how to setup a Raspberry Pi Full Desktop Image with all the basic configuration completed so a fresh build can be put on an SD card from an image so you wont have to start from scratch for each new project/rebuild.

We will be using the official Raspbian Jessie OS but removing all the games and un-needed applications still keeping the desktop GUI, another stripped down image will be made with no GUI later.

**work in progress**

Raspberry Pi Real Time Clock (RTC)

How to setup a Real Time Clock on a Raspberry Pi B v1.1

 

If you didn’t know, the Raspberry Pi doesn’t hold the time very well, this is because there is no on board Real Time Clock.

To keep the devices time accurate we need to add a module that holds the time whenever the RPi has no power running to it and then updates the RPi with the time saved on the battery powered module when the full power is restored and the system starts running again.

piTank Power Bar v1

To run the mains powered electrical items of the piTank I wanted a remotely controllable power bar connected to the same Raspberry Pi as the piTank software.

Future post:The piTank power bar will include input connections for thermal probes, water sensors, switch inputs and an external connector to a viewing panel mounted on the front of the cabinet.

What is the first thing you do when you have a good idea, Google it to see if anyone has done the same!

My Raspberry Pi Aquarium Controller

So I have my first fish tank and some Raspberry Pi’s lying around and decided to create a kinda of controller/monitor with the future functionality of a data logging.

There are already lots of ideas out there for a Raspberry Pi based aquarium controller, but as a first time project I wanted to create something as much on my own as possible. Systems like the ones below do look very nice and when I flip back to what I intend to make it isn’t as good… but its exactly how I want it to be and I made it!

Current Raspberry Pi aquarium controller projects:

Google search result on the RPi forum
Open Aquarium
RPi Tank Monitor
Raspberry Pi Monitor
ReefPi – I was really interested in this one, they have some great ideas but as with many projects, lots of people say they will do things and then back out for whatever reason, the original people loose interest or they cant find someone who is willing to actively do the hard bits of hardware/software. This project is still new but I get the feeling not enough people are creating and there is just commenting.
