Some images from 1st TOG photo exhibition

And breathe..

Huge thanks to everyone who came along to the first TOG photographic group show in Hendron’s Collider. Much stress, much fun, (too) much wine… For those who didn’t make it, here are a few images from Eadaoin’s Facebook Gallery. LOADS of images floating about, which I’ll collect and put in a full gallery soon.

I’m hoping to run the whole 10 week concept to exhibition cycle again soon. Watch this space..

Printing printer parts

TOG’s laserjet printer was mostly working, but the two buttons on top were stuck and unusable. Each button was supposed to have a little right-angled lever connecting it to its microswitch. The problem was that one lever had come out of its mounting, and the other one was missing altogether.

Button mechanism removed, showing where the missing lever should be.

The large button has its lever; the small one doesn’t.

Missing. Gone. Not rattling around inside the printer, or sitting in a corner of the classroom. Just gone. But we have one lever left. If only there was some way we could make a copy of it…

The part is composed of a few straightforward shapes which were modelled in OpenSCAD.

Then the design was printed on the 3D printer.

Printing in progress.

The first print didn’t work because there was too much of an overhang. The second, improved design didn’t stick properly to the bed (small fiddly prints benefit from a brim). The third one came out nicely.

L-R: original part, two failed prints, successful print

The learning curve.

After cutting away the brim and overhang support material, the new part fits under the button…

Same button mechanism, now with two levers.

Good as new.

… and the printer buttons are working again.

Grubby, but working, printer buttons.

Printer buttons working again.

(And if your HP2200dn has also lost its button levers, the STL file is up on Thingiverse.)

May Book Club

The next meeting of the TOG Book Club is 7:30pm, Friday 30th May 2014, and we’ll be reading Embassytown by China Miéville

The plot of the novel surrounds the town of Embassytown, the native alien residents known as Ariekei, their Language, and the human interaction with them. The novel was well reviewed and won the 2012 Locus Award for Best Science Fiction Novel.

Big thanks to everyone who came to our April Book Club and read The Quantum Thief by Hannu Rajaniemi.

All are welcome to come and chat about the book (members & non-members).

Speaker – Sinead McDonald
Title –  How to pretend you know stuff about stuff
I’m a visual artist, and a graduate of the Art in the Digital World Masters at NCAD. I like to make machines that make people think about things, like quantum mechanics or emotions or time travel or regrets or alternative realities or music or long-defunct Victorian crazyscience. I play with the blur between science and fiction, and I get a LOT of help and collaboration. I’ll be talking about a few past projects, the people who helped me and made me look good, and the stuff they taught me that helps me pretend I know stuff about stuff.

Speaker – Jamie O’Leary
Title –  Blender and the Creative Space
Blender is a free and open-source 3D computer graphics software product used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games.  The talk will be on what blender can do for you as a hobbyist.


Speaker – Diarmaid McManus
Title –  Spammers hate him! How one weird trick can keep your accounts secure online
Social media accounts are valuable to scammers and spammers, who want to make a quick buck off your reputation. Here’s a few tips to help make your accounts harder to abuse.


Speaker – Aoife Crowley & Mary Plunkett
Title –  Made It
Dublin is a city that has been known for its creative and literary heritage. More recently the tech community has elevated Dublin into the new age, but for some, this is a closed circle. For other, they may have the skills, but lack the confidence to bring their ideas to life. You may know how to build an app or create a product, but do you know how to bring these things to market? With Made It, we want to foster a greater sense of community and engagement between the spheres of technology, creativity and entrepreneurship and see how the successful projects we see around us came into being.

Photographic group exhibition opens on the 25th April
