Everything TOG in August, craft, code, lock picking, CAD, book club, free events in Dublin!

Hello all,

Craft Night: Runs on Wednesdays, the 8th and the 22nd August at 7pm. Knitting? Crochet? Embroidery? Laser cutting? 3D printing? Join us and work on something you know, or learn something you don’t.

We are supporting the great Dublin Raspberry Pi Jam crew to put on their first jam. It will be hosted in the Science Gallery on Saturday August 11th from 12:30. You can join the waiting list on the main event page -> https://ti.to/dublin-raspberry-pi-jam/first-pi-jam

Electronics and Micro Controller Night: Runs on Mondays, the 13th and 27th of August at 7pm. Arduinos, Raspberry Pis and Intel Galileos are just some of the things you can work on down here, or try our introductions to electronics worksheet. Recommended you bring your own laptop.

The Science Fiction Book Club gets ambitious this month, we’ve chosen two Philip K. Dick novels: A Scanner Darkly from 1977, and Do Androids Dream of Electric Sheep?, the inspiration for the 1982 classic filmBladerunner. The meeting to talk about them is the last Wednesday of the month, 29th August.

Lock-Picking: Runs on Monday 20th of August at 7pm. Come down and try your hand at cracking open tumbler, tubular or warded locks.

Open Social: Runs on Saturday the 18th of August at 7pm. Join us for an evening of conversations, games and our glorious hand made wood fired pizza.

Coding: Runs on Monday 20th of August at 7pm. Come down and work on a project or help others with theirs. Laptop and project of your own recommended.

Wikipedia Editing: Runs on Wednesday the 29th of August at 7pm. Ever wondered how to get started editing Wikipedia? Come along and will get you adding to the world’s largest open collaborative knowledge project. All are welcome, no editing experience is necessary and the event is free, just turn up with a laptop to start editing.

If you happen to visit EMF Camp from the 31st of August, be sure to drop by the Irish Embassy.

Remember, TOG is run by members, if you want to get involved and help run events + get full access to the workshop and facilities, talk to any member about joining.

TOG Dublin Maker BBQ

On Sunday 22nd July, from 14:00-18:00, we’ll be holding a BBQ in the space as a bit of a wind-down following Dublin Maker 2018.

Maker is always a hectic day, but great fun too. It’s great for us to have a lazy, wind-down afternoon in the space. Drop in and say hello. We’ll have some food and drinks on the go, and a bit of banter too. Hope to see you there. We’ll be sure to give you a tour of the space if you’ve never been in to see us before.

Upgrading the 3D Printer

After some TLC was offered up to Tog’s 3D printer, by way of a little restoration and tuning, it became very clear that the current hotend was on its way out.

Tog’s Lulzbot Taz 3.0 FDM 3D Printer has been deprecated and is approximately 3 versions behind the current technology. What’s worse is that the nozzles for the extruder were not standardised, byt comparison the E3D V6 style hotend and nozzles have been almost universally adopted. Even by manufacturers.

So, in case you’ve been wondering why Tog’s 3D printer has been out of action for approximately the past 2 weeks, thats why. I have started the process of upgrading the extrusion system to use an E3D V6 style hotend. Initally I tried some chinese clones (the designs are GPL’d after all!) but found their quality seriously wanting. I cannot comment on the genuine article as the order appears to have been lost in the UK postal system for the time being.

The main issue with changing from the Lulzbot Budaschnozzle v2.0 configuration to an E3D V6 is that there is apparently no models or designs we can draw from to make a mount. So I had to design one from scratch. I say design one, but actually there were many designs. The first was a laser cut wood mount – It worked but it just didnt feel like it what I was experiencing was truely level.

As I am lucky enough to have a Prusa i3 MK3 printer of my own, so I have been iterating over the design and protyping a lot of different variations to see what works. When I say a lot, I do really mean a lot…

I think now I have finally I settled on this design:

The current backplate – which is already a reasonably good hot-plug-able system, is replaced with an altered one. This new one comes with a 5 x 7 grid (14mm spacing) of 4mm hex cavities which will be used as a ‘mechanical key’ to home whatever tool is installed. This way we come a little bit closer to achieving “true level”, mostly. It also has the added feature of supporting many different applications in the one piece – wheras originally it only supported the extruder assembly and the stock nozzle, this new design could even be used for things such as drawing circuits or as a plotter.

As I’ve been using AutoDesk Fusion 360 to design it, you can use this link to see the current model and download it if you so desire. It is still very much a work in progress,  however.

Memory Lane -> 2009

Sometimes we get a bit nostalgic for the early days in Tog.  We had our first tiny place in Arran Quay, a small three room office unit. We started running our first workshops and open days for the public there. We have changed a lot in the last nine plus years. To showcase the early space and show oof photos of when we were all much younger, we have created a photo collage of what we got upto in 2009. It was started way back during Science Hackday Dublin but only finished during our recent finishaton.  You can now see it hanging on the wall in our space or view the individual photos on our gallery.
