The ARMinARM board is an STM32 ARM Cortex-M3 microcontroller add-on board for the Raspberry Pi Model B+ with a focus on flexibility and hackability, while still being easy to use. The STM32 runs on 72MHz and has 512KB Flash and 64KB SRAM memory.

For the last few weeks I have been putting together a Modular LEGO Train Layout. Each Module is based on a 900mm X 1200 X 6mm MDF board mounted to a 70mm X 20mm Timber Frame. The Module use a series of Dowls and Holes to join the Modules together. This arrangement allow for easy storage and transportation to LEGO Shows and Displays.

You can share your Raspberry Pi’s files and folders across a network using a piece of software called Samba, a Linux implementation of the Server Message Block protocol. The following instructions will set your RPi to share its files on your local network and be accessible by Windows.

I have been patiently waiting the release of the new Raspberry Pi B+ Expansion Board from Suptronics, the X300 for the last couple of months.The X300 is Raspberry Pi B+ Expansion Board that adds WiFi, Bluetooth, RTC, Microphone input, 3.3W Stereo Audio & SPDIF output, IR receiver, SATA and More.

Connecting an Arduino to a Raspberry PI using I2C

I’m intending to use several Arduino Boards as a cheap means of controlling a number of RFID Readers which will be used to detect the position of Locomotive Engines on my LEGO Train Layout. That said I need a way of connecting these Arduinos to the Raspberry Pi which is the Master Controller for the layout.
The easiest way of Connecting an Arduino to a Raspberry PI is using USB, however the PI’s USB ports are need for WiFi Keyboard, Mouse, etc. So in many cases USB is out, especially if you are using a Raspberry Pi Model ‘A’.

Raspberry Pi ‘Plate’ or Add-on with 16 Ch. Servo & 16 Ch. GPIO

Over 12 months ago I came across a “I2C: 16 Channel, 12 bit PMW Servo & I2C 23017, 16 GPIO” add-on board for the Raspberry Pi made by a U.K. company called, Pridopia. At the time I thought too myself, “What a great idea”, but I had no immediate use for one. That has since changed thanx to my Raspberry Pi powered ‘LEGO Train Layout‘ I’m currently constructing.

Using 16-Channel I2C, Servo Module with Raspberry Pi

You want to make a cool robot, maybe a hexapod walker, or in my case I want to use 9g Micro Servos to switch the points on my LEGO Train Layout I’m constructing. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your Raspberry Pi only has a single PWM output on GPIO-18! What now?

It’s time to get excited all you Raspberry Pi enthusiasts as pretty soon, you’ll be able to pick-up an official touch screen to connect to your Raspberry Pi. Plus, a beefier new Raspberry Pi Model A+ is incoming, according to Eben Upton, CEO of Raspberry Pi Ltd. Upton made the announcements during a recent interview at TechCrunch Disrupt Europe in London.

Whilst searching DX.com, I came across the Waveshare DVK512 Expansion Board suitable for both Raspberry Pi B+ and Banana Pro. The Waveshare DVK512 Expansion Board comes equipped is 4x user defined buttons and LEDs, plus interfaces sockets for add-on Modules of almost any type you can think of.

Using a PS2 Dualshock Controller with Raspberry Pi

I have spent the weekend experimenting with my Raspberry Pi’s. One challenge I set myself was to get a Sony PS2 Dualshock Controller working with Raspberry Pi. The main reason for this, was to allow me to control a BrickPi Robot without using a Mindsensors PS2 Controller Adapter connected to the Brick Pi. This leaves access to the maximum number of four NXT Sensor Ports on the BrickPi Board.

Raspberry (Banana) Pi to PC using a Serial Connection

Using a Connection via a Serial Port is a low-level way to send data between the Raspberry (Banana) Pi and another computer system. There are two main ways in which it can be used:
  • Connecting to a PC to allow access to the Linux console. This can help to fix problems during boot, or to log in to the Pi if the video and network are not available.
  • serial interface. This can be useful if you want the Pi to control another device.

The EVB is a shield (or called cape) for Beaglebone ‘Black’ (BBB). It fully support LEGO® MINDSTORMS® EV3 system, with both the hardware and software! The BeagleBone ‘EVB’ is compatible with all LEGO® sensors just like the EV3 Brick. 100% compatible! It allows the EV3 Virtual Machine (VM) to be run on the Beaglebone ‘Black’.

The Banana Pi: Upgraded Alternative to the Raspberry Pi

As the name implies, the Banana Pi is a clone of the Raspberry Pi. Just like its predecessor it has 2 USB ports, 26 GPIO pins and draws a tiny amount of power. However, with Dual Core 1GHz A20 CPU, 1GB Ram, Gigabit Ethernet, Infrared receiver and SATA adapter, it packs a powerful punch.
