London Arduino

Tonight was my first time along at the London Arduino Meet Up.
The London Arduino Group is of a similar idea to the Raspberry Pi Jam events that I’ve been to
before. It is a group of people who want to share knowledge about the Arduino platform and start to
innovate across other platforms.

This month we had presentations including hobby electronics, internet controlled LED’s and 3D
printing.

Using an Ethernet shield, Christian, put together a set up where he was able to control the status
of an LED in his web browser. This was done on a local network (sorry guys who wanted to take
control of his little light) where he showed two methods of flicking the switch.
The first method he showed off was to use the arduino as a web server and construct the html on it
as well. Then it was a simple matter of connecting to the IP address that was defined on the
arduino and hey-presto it worked.
The second method that he demonstrated was a little more complicated involving node.JS, sockets and other technical jargon that I didn’t catch.

On a similar vein we had Liam demonstrating the use of a TP-Link Wireless N Nano Router (TL-WR702N) to connect an arduino to the internet. He argued that the use of WiFi shields is overly complicated compared to Ethernet shields, as well as being a lot more expensive  So if you are willing to have a slightly bigger package then you can connect the Ethernet shield to the nano router and leave that to sort out the complicated subtleties of wireless connections, allowing you to get on with innovating your wireless solution. Another thought is that a nano router is much more versatile than a WiFi shield because it can be plugged into a computer, games console, Raspberry Pi, or any other device that has an Ethernet socket.

In the realm of Hobby Electronics we had Danny, who was plugging his first ever kit robot. Orionrobots.co.uk is his creation and is where he is selling his first his own starter kit robot. In this kit you will find everything that you need to to construct a small chassis with 4 wheels controlled in pairs (left and right) by a L298n dual H-Bridge controller board which is interfaced to an Arduino Uno R3 (provided in the kit). With a easy fit design, you only need a screwdriver to put this kit together making it perfect for anyone who is; unsure with tools, in need for a robot chassis quickly, or just lazy.

The final talk of the evening was from Mark, on behalf of another London Tech Meet-up group, Future Manufacturing, who have a keen interest in 3D printing. They are really keen to see cross collaboration between our two groups on various projects including potentially the Luma Module Interactive Spaceship. The Luma Module is a KickStarter project where they want to build a spaceship that lights up when people interacts with it. This spaceship will then be shipped (no it won’t fly itself) to Nevada for the Burning Man art Festival at the end of August 2013.

My first Rapsberry Jam

Well last night, in preparation for getting myself a Raspberry Pi I attended the London Raspberry Pi Jam Night at the Mozilla space in London.
I won’t bore everyone with a full write up of the night and instead if you are interested, point you to my good friend The Scientific Moustache’s blog post on the night.

Instead I will be giving you my impression as a newbie at these events.

I arrived early with my friend as he is a co-organiser, and it seemed to be quite a quiet affair.
As people started turning up and getting to work with their projects and lending a hand to others with their own projects. I started to get into the spirit of the evening, lending my own advice and opinions, although very often I was proved wrong. Alas I was surrounded by new technology, and a new programming language, so I’m not surprised that I was no help.
So despite not being any help myself, I really was intrigued by some of the projects others were doing, from controlling a Lego NXT robot, to taking pictures using a webcam and controlling an Arduino Uno, to just trying to connect it to the internet.

I really can’t wait for my Model B RPi to arrive so I can start playing with it, and of course I’ll update on here with my progress.

The Raspberry Jam is in no way affliated with the Mozilla Space or the Rapsberry Pi Foundation. Raspberry Pi is a trademark of the Raspberry Pi Foundation.
