An HDMI screen is next (although if you have an older screen you can get a VGA-HDMI converter – also useful if you want to swap between your computer display and the RasPi). Then a USB keyboard and mouse (you likely will have this on the computer you’re currently using). To power this, you will need a microUSB power supply (a phone charger will do as long as it’s at least 1 Amp). You can use a Model B, a Model B+ or a Pi 2 – I recommend the Pi 2 as this has a quad-core processor and is a lot faster than the earlier models. So – all this sounds interesting, but what you do need to get going ?įirst of all – a Raspberry Pi (or RasPi, as they are known). The main difference between the II and the 3 is that the II will put out 1 Amp to your railway while the 3 will put out 2.5 Amps. There are several versions the original Sprog is no longer available (it was a kit from MERG), but the Sprog II and Sprog 3 are. The difference here is that this one is the size of a matchbox, and has no external user interface – it’s designed for use via a computer. One thing it isn’t is a young child ! No, a Sprog is a Digital Command Control command station – similar in function to those sold by Bachmann, Hornby, Digitrax, etc. I’ll note the differences between using these when we get to them. Now … Wheezy has been around for a while and has the wrinkles ironed out, whereas Jessie was released on the 29 th September and people are finding some parts don’t work quite as expected. The latest version is based on the version of Debian Linux known as “Jessie” (named after the cowgirl in Toy Story the previous release was Wheezy, the penguin in the film and before that was Squeezy, the LGM !). Plug in a USB mouse and keyboard, connect to a monitor, power up and off you go ! As mentioned, it uses Linux and the recommended distribution is referred to as Raspbian. Several versions have been released the latest (and the one I recommend you get) is a Raspberry Pi 2 – but if you have an older model, it will still work for this project, just not as quickly.

The price of a basic unit is only around £25, and you will also need an SD card for the operating system to install on.

Ī Raspberry Pi isn’t some fruity dessert instead, it is a proper Linux computer that is the size of a credit card – that’s right, a full computer that can sit in the palm of your hand.

At the time of writing, the current version is 4.0.1 Production you can also get great support from the developers via the Yahoo group.

You can learn all about JMRI at their website. You don’t have to use everything personally, I only use Decoder Pro.

The three main applications JMRI has are : Decoder Pro (an easy way to program your DCC decoders) Panel Pro (a design and operations area for control panels) and Operations Pro (creates manifests for the work a particular train will do). Why should you use it ? Well, command stations are not always easy to use, especially in a complex layout ! And sometimes, you just want something simple without having to go through many button presses. It sits between your computer and your command station (your DCC controller), and passes your instructions to your command station to implement.

Well, JMRI stands for the Java Model Railway Interface, and it is a free Digital Command Control suite of applications to allow you to control your railway from your PC, Mac, or Linux box. You may have heard of a DCC application called JMRI, but not know much else.
