The Hills Are Alive With The Sound Of Train Whistles

In Northern England, the hills used to be home to steam trains. The trains have long faded into history, but the sound of their whistle is making a brief return. Artist [Steve Messam] has created “Whistle” as part of The Great Exhibition of the North. [Steve] doesn’t cover the installation on his website yet, but there have been a few great articles about it in the local press.

Whistle consists of 16 steam engine whistles around¬†Newcastle. From June 22 to September 9, you can hear the whistles at 1pm. First one whistle sounds, then another, then another after that. In all, 16 whistles are included in the art installation, all controlled by Raspberry Pi computers. The Pi’s were programmed by Nebula Labs. Tech details are slim on this one, but we’re guessing each Pi has a Cellular radio built-in.

The whistles used in this installation aren’t old train whistles. They are brand new cast brass whistles based upon the original steam train sounders. The compressed air available today doesn’t sound exactly like steam though, so the brass whistles were modified to sound more authentic. [Steve’s] idea is to get the whistle as perfect as possible, which will trigger the memories of those who are old enough to have heard the originals.

The Nottingham Hackspace

Hackerspaces (or hackspace in this case) come in all shapes and sizes, from those just starting up, to some that are very impressively equipped. [Dominic] wrote in to tell us about the Nottingham Hackspace, which would fall solidly into the second category. We’d invite you to take a look at their intro video after the break, but be prepared to wish you lived near their location.

If you do happen to live there, in addition to a nicely polished website and intro video, they have nearly 4500 square feet of space at their facility. Naturally they have the now ubiquitous 3D printers, but they also have an impressive array of more traditional as well as computer-controlled tools. These include a lathe, welders, CNC router, laser cutter, and even basic PCB-making facilities. Storage space is also included, both for member projects and bicycles.

So be sure to check them out. They have around 130 members right now, but naturally would love to see you there! Continue reading “The Nottingham Hackspace”
