The Dublin Hackerspace
As always at the BBQs at tog there is fire and dismantling of stuff involved. Group of us on Sunday during the BBQ took apart an old welder that was quite useless and converted it to a spot welder check out the video down below.
We also put up a few more pin hole photos of which will be posted in a few weeks.
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.
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.
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.
After cutting away the brim and overhang support material, the new part fits under the button…
… and the printer buttons are working again.
(And if your HP2200dn has also lost its button levers, the STL file is up on Thingiverse.)
TOG member Sinead took photographs of the hacked knitting machine for TOG’s exhibition in the Exchange gallery. You can view the full photoset here.
The knitting machine will be demonstrated at the closing event on Friday night.
On June 16 1904 in the novel Ulysses, Leopold Bloom got a bar lemon soap from Swenys chemist in Lincoln Place, Dublin. You can still do that to this day. He never paid for his! On Oct 13th 2013, we made lemon soap at TOG…..or lemon and oatmeal to be precise. It’s our first go at soap making, so we’ll have to see how it turns out. Like a fine wine, it needs time to mature now, so we’ll update the blog in a few weeks time. We might want some testers. If it all goes well, we might even do some more. Contact us, if you’re interested in soap making.

On Saturday at the TOG open social, we built our eggbot kit. It went together quite easily, and within about 2 hours we were doing our first plots.
Video and more photos here.

This coming Saturday 17th August, is TOG’s regular open social. It’s a great opportunity to drop in, hang out and meet some of the members and visitors. The space will be open from afternoon until late. Bring beer, food, gadgets!
We also have a egg-bot kit. An egg-bot draws on eggs and other similarly shaped objects, such as light bulbs and ping pong balls. We’ll be assembling the kit during the evening and trying to get it running. You can read all about the egg-bot here….. http://egg-bot.com/ Come in and give us a hand!
