December Present Making Wed 3rd Dec

As the holiday season swings by, Tog will be running a present making session with help from the Dublin Favour Exchange
Day: Wed 3rd Dec
Time: 7-9pm
Cost: free — but bring some materials if you can
Where: Tog!
We will be making 4 seasonal delights:
  1. Carrot Cake
  2. Apple Jam
  3. Cards
  4. Soap
Please bring relevant materials if you can: for the card you need liquid or stick glue. We have cards and paper. Favour Exchangers will be bringing some special teabags for the cardmaking!
We have everything we need for the soapmaking but have limited spaces

On intergalactic space travel, sound waves, the Guzman prize, and human communication

So I’m just back from a 400-odd year space flight, which felt like a weekend, but actually took 270 years, depending on where you’re standing. Imagine the jetlag! Sunday was mostly taken up with the first recorded arts-based intergalactic mission in human history, also known as Starship Hack Circus. Starship Hack Circus

My involvement in the project started some months ago, with a trip to the utterly brilliant Hurdy Gurdy Radio Museum in Howth, Co. Dublin, and some research into early radio transmissions for some upcoming workshops. It was in Howth that I first learned of Fred Cummins and his Guzman Boxes. From Wikipedia:

“The Prix Guzman (Guzman Prize) was a 100,000 franc prize announced on December 17, 1900[1] by the French Académie des Sciences to “the person of whatever nation who will find the means within the next ten years of communicating with a star and of receiving a response.” It was sponsored by Clara Gouget Guzman in honor of her son Pierre. Pierre Guzman had been interested in the work of Camille Flammarion, the author of La planète Mars et ses conditions d’habitabilité (The Planet Mars and Its Conditions of Habitability, 1892). Communication with Mars was specifically exempted as many people believed that Mars was inhabited at the time and communication with that planet would not be a difficult enough challenge.[2] Nikola Tesla claimed in 1937 that he should receive the prize for “his discovery relating to the interstellar transmission of energy.”[3] The prize was awarded to the crew of Apollo 11 in 1969.

Cummins, a keen astronomer and radio enthusiast, had retired to Howth in the 1930s, where he built hundreds of basic radio kits to try to detect alien transmissions and claim the prize. Each used a helical resonator tuned to a specific narrow band of frequencies, in an attempt to pinpoint an ET signal. Ultimately, Cummins failed, but left behind a huge legacy of hundreds of beautifully crafted yet utterly useless ‘Guzman Boxes’.

Earlier this year, fellow Tog Dublin member Jeffrey Roe and I were gifted the shell of a Guzman Box from the Cummins estate, little more than a wooden cube with a helical resonator attached, to restore and develop for the Hack Circus voyage. We decided to flip the Guzman prize on its head – instead of looking for extra-terrestrial communications, we would examine the signals that have left earth, to wander indiscriminately through the galaxy, acting as unwitting human ambassadors. With the help of woodworker extraordinaire Javier Leite we were able to return the box to something of its former glory. Jeffrey worked on engineering and code, while I researched appropriate transmissions, ably abetted by Benjamin Schapiro in the States (thank you again Ben!).

The box plays the most historically significant transmissions from exoplanet exploration, catalogued by where in the galaxy that transmission is now reaching. For example, Reginald Fessenden’s Christmas Eve 1906 transmission of Handel’s Largo (now reaching the planet HD 37124c in the Taurus System – the furthest reach of human art), a moving recording of Allied troops landing in France, 1916 (just now reaching the first-discovered-and-closest rogue planet CFBDSIR2149-0403) to the fall of the Berlin Wall, transmitting to possibly our closest neighbour in the habitable ‘Goldilocks’ zone – Gliese 667cc. What must our neighbours think of us?

Because it’s Hack Circus however, and that means never taking *anything* for granted, Jeff and I decided we couldn’t count absolutely on human means of aural detection. In space no-one can hear you scream (or sing along to Ken Dodd’s 1965 classic Tears for that matter – just now reaching habitable exoplanet Gliese 163c), so we needed a means to transmit audio through the vacuum of space, and through whichever aural cavity alien physiology might have evolved. The safest bet was bone conduction, and a method ruthlessly stolen from Dave McKeown at Artekcircle earlier in the year – biting down on a copper rod attached to a motor, attached to an amp. Here’s a tweet of @metabrew, demonstrating technique –

And the Guzman Box itself: IMG_20140914_184218 The Guzman Box will be available to try at Tog Dublin on Culture night – this coming Friday 19th September, along with the Tachyonic Antitelephone , and a host of other art, craft, tech, and engineering projects from fellow members.

3D Printer Reprep Code Improvement

220px-RepRap_'Mendel' SmartController

On Saturday 5th of October from 2pm-6pm TOG is holding a 3D Printer Arduino code improvement day.

3D printers are all the rage at the moment. However they are not without their faults and some of the budget, hobbiest models could do with an improvement or two.

The aim of the afternoon will be to improve the Reprap code to add extra features.
The stand alone reprap uses an Arduino based stand controller to print without needing a computer connected.

A second project would be to add bluetooth wireless operation.

The controller being used is:

The display is:

http://reprap.org/wiki/RepRapDiscount_Smart_Controller

and the code is:
https://github.com/ErikZalm/Marlin/tags

http://reprap.org/

Whoever works on the project will be given access to a working Reprap with all the hardware for testing the setup. There may be a budget for the time involved if working on the code after the first day. The main plan for the day is to specify what changes need to be made.

No need to book, just show up. Anyone with an interest in 3D printing is welcome. While the event is free we will be asking for donations to cover the hosting costs.

Hack Across Europe in Dublin

HackAcrossEurope

At the last Lockpicking Night (12th February) we had a special visitor to the space. Darren Kitchen is hacking his way around Europe, and last week he was in Dublin. He stopped by the space and filmed a segment of this Hak5 episode from our humble little brown leather sofa.

We’d like to take this opportunity to apologise for our boisterous lockpickers (you should hear our parties…), and hope it doesn’t distract too much from the great content about captive portals. By all accounts everyone had a great time, so if Darren is making his way to a town near you it’s worth looking him up. If not, there’s plenty at Hak5 to keep you entertained.
