Coder Girl Hack Day

IDGC_2015-195x250 We joined with CoderDojoGirls, Girls Hack Ireland, Intel Ireland and Coding Grace for an artsy themed coding hackathon to celebrate International Day Of the Girl and EU Code Week.

This is a one day event focusing on programming music, developing game apps and learning about hardware. The event is broken up into a number of tracks giving you the chance to pick someone that suits everyone.  If you’ve never coded before this is the right place to start! If you’ve coded before, betcha you’ve not programmed music using Sonic Pi or made a story-telling game with Fungus Games & Unity3D. It you like making physical objects you can pick the imaginative engineering.

In TOG, we have teamed up with Intel to run the imaginative engineering track. We will be focusing on making Hardware Hacks. We will be soldering up electronics, programming Galileos and making laser cut projects. No previous skills are necessary for this track.


Date: Saturday, 10 October 2015 from 10:00 to 16:00 (IST)

Location: DCU Innovation CampusOld Finglas Road, Glasnevin Dublin 11

Tickets: Below:ibf2lmufEkwHIx


This workshop is suitable for children aged 11-17. All under 18’s must be accompanied by a guardian. Guardians do not register for a ticket here. Parents who are interested will have the opportunity to learn Python on the day from Coding Grace.


What is Coder Dojo?

We hacked together a cool hangout that puts the real power of the internet and technology in the hands of the Irish youth. The true power of the net comes from coding, designing and having fun. CoderDojo is a place where you can learn from others and share what you are doing! Each week we have a hands on session with technologies like HTML5, App Development, PHP or Python. See

What is CodingGrace?

Coding Grace are a group of developers based in Ireland who love to code and do other geeky and not necessarily crafty activities. Some of us code full-time, or just for fun (or both). We have people who are part of other technical user groups such as Dublin ALT.NET, GameCraft, Python Ireland, Ruby Ireland and more, We provide female-friendly workshops and events in an environment for developers and aspiring developers mentored by diverse instructors from the industry. See

What is Girls Hack Ireland?

Girls Hack Ireland is a program developed by The Insight Centre for Data Analytics (@insight_centre) with the aim of generating knowledge & interest among younger girls to pursue the academic disciplines of STEM (science, technology, engineering and mathematics) subjects through creative, interactive learning.

NERP Tonite! Neural Interfaces for Advanced Prosthetics

NERP is not exclusively Raspberry Pi, the small computer and embedded systems interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago.


Tucker Tomlinson is a familiar face around the shops at Pumping Station One. He’s also a Postdoctoral Scholar in the Laboratory of Lee Miller in the Department of Physiology at Northwestern University Feinberg School of Medicine. Tucker’s work in the Limb Motor Control Lab* focuses on neural interfaces for advanced prosthetics.

Data acquisition systems used to record neuron activity typically work with lots of channels of analog-to-digital converters that measure tiny voltages and currents very fast. In Tucker’s words:

“I’ll be discussing the problem of recording directly from neurons in the brains of monkeys and humans. There will be a few slides and videos to help describe the basic science and technical challenges that we face when tackling this problem, but the session will be mostly informal discussion driven by whatever the audience finds interesting.”

* the phrase “motor control” means eye-hand-brain, not steppers

Board Game Night: Small World

Its that time again, first friday of the month! Board Game Night!

This Friday 2nd October starting from 6:3o pm the games we’ll be playing are Small World and Small World: UndergroundThis’ll be a family-friendly event, with the games recommended for ages 10 and above.

In Small World, players vie for conquest and control of a world that is simply too small to accommodate them all.

Designed by Philippe Keyaerts as a fantasy follow-up to his award-winning Vinci™, Small World is inhabited by a zany cast of characters such as dwarves, wizards, amazons, giants, orcs and even humans; who use their troops to occupy territory and conquer adjacent lands in order to push the other races off the face of the earth.

Picking the right combination from the 14 different fantasy races and 20 unique special powers, players rush to expand their empires – often at the expense of weaker neighbors. Yet they must also know when to push their own over-extended civilization into decline and ride a new one to victory!

Science Hack Day Dublin 2015

Science HacScience Hack Day Dublink Day Dublin is a 36 hour hardware and software hackathon. A social event with creativity and love of science at its heart.  Each year it brings together coders, designers, scientists, engineers and makers simply to make interesting things. Why? For adventure, for playfulness, for science! The event takes place in UCD on the 14th & 15th November.

Here in TOG, we are proud to be supporting Science Hack Day again. Since it inception we have always found it to be the best community hackathon around.  It’s rare these days for big events to keep their community feel. Now entering its 4th year, and with an FAQ that just gets better each year, you have no reason not to go . The ideas for this years event have already started to pile in. They include lasers, can we say more ? pew pew. For tickets see eventbrite.

Washing Machine = Patio Heater

heaterTake the TOG test by selecting the correct answer.

Q: Your washing machine dies and you get a new one. What do you do with the old one?

1. When your new one is delivered, let the delivery crew take the old one away.
2. Take the old one to your local WEEE recycling centre.
3. Take the old one apart to see how it works. Harvest all the useful parts and use the parts to make something else.

The correct answer of course is number 3, but you knew that anyway. That makes you the kind of person that would probably like TOG.

So the trusty washing machine from 1996 was getting a bit tired. The drum bearings needed replacing (a relatively straightforward job)…they were squealing louder and louder. The drain pump started to make a racket and wouldn’t empty after a wash…. maybe it was seized or something jammed in it. Looking inside, it was obvious that it was leaking a bit also, probably when it was spinning. Time for a new machine.

Taking apart the old one, there’s a lot of interesting and useful bits. There’s a nice AC motor and an electronic speed controller. There’s some pulleys and a drive belt. There are also assorted hoses, electrical bits and valves. There’s also the stainless steel drum. Removing the drum from its aluminium mounting, and adding a few steel legs….. we have instant patio heater. Who needs a chiminea! Being stainless steel, it wont rust either.

We gave the new heater a test run this week and it worked a treat. Come in and stand around it at the next open social. Lots of pics here

Why Discourse?

Why Discourse?

I’m not sure people understand maintenance burden.

Google groups has been a maintenance headache. Probably one of the smaller maintenance headaches, but still a problem.

With most of the system’s that PS:One has developed over the last several years, new member handling, auto admining of the 40 or so systems group member’s, etc has been automatic.

PS:One cycles through motivated individuals pretty quickly. If we ever come across a gap between an old productive member and a new ones, we lose something. There are a few ways to handle this: One is to stop burning people out, and to make sure that gap doesn’t exist. The other is to reduce the amount of information that can fall in that gap.

Per application user management is a great way to burn out technologically creative individuals. I’ve seen it happen a few times.

Our current systems approach is to reduce maintenance burden to deal with the first problem. The other is to make most of the tasks a systems person needs to carry out be automatic. Google Groups has not presented us with much as far as solutions to deal with these 2 problems. They offer no api to add or remove subscribers, and are notoriously difficult to write scraping tools for, and offer no guarantee of long term stability for scraping tools.

We have investigated a few potential solutions for mass communication in the membership. Most of these focus on web forum technology, as we are hitting the magic threshold where mailing lists are no longer the right solution due to message volume. So far discourse is the most promising.

Jeff Atwood Is one of the main developers and founders of discourse. Previously he started stack overflow with Joel Spolsky (the Joel on Software guy), and has been running a blog called coding horror since about 2004. He’s got some experience with online communities and a lot of opinions and practical experience on what makes them work well and what doesn’t, including a few very well known implementations of online discussion platforms. I don’t always agree with his technical and social decision minutia, but I have to understand that he’s coming from a wealth of experience, and has left the discourse discussion platform open to plugins and extension.

Make Your Own Clock at Craft Night Tomorrow

Improvised Timekeeping Device (@phooky)

Improvised Timekeeping Device (@phooky)

You may have read about Ahmed Mohamed, the 14 year old boy who was arrested Monday for bringing a clock to school. Ahmed built his own digital clock out of spare parts on Sunday night and brought it to school on Monday to show his Engineering teacher. He was arrested – wearing his NASA shirt – after his English teacher claimed it “looks like a bomb.”

Join us in standing with Ahmed and promoting Engineering in schools on Thursday night by making your own DIY clock. Browse our junk drawers, grab some LEDs, and slap together your best Improvised Timekeeping Device. We have plenty of soldering irons and there will be people around to help out if you’re new with electronics. Philosophers will also be on hand if you have trouble with the concept of time itself.

Follow Ahmed’s situation on Twitter.

Craft Night is one of NYC Resistor’s weekly open-to-the-public nights.  We’ll be there from about 6:30 p.m. until time stops making sense, at 87 3rd Ave (and Bergen Street) in Brooklyn, just a few blocks from the Atlantic Ave / Barclays Center subway stop.

X,Y,Z Finder for the ShopBot

Click here to view the embedded video.

The PS:One ShopBot is a great CNC machine that has the benefit, among other things, of being huge, allowing for a lot of cuts on large pieces of material. One of the difficulties working with the machine, however, is getting the bit at exactly 0,0,0 in the X, Y, and Z axis so that if you need something cut at exactly six inches from the edge of the material, it will be exactly six inches. There is already a built-in method for setting the Z axis, using a metal plate and clip and running a specific program on the ShopBot, but there is no such program for setting the X and Y, requiring the user to manually position the bit. This can lead to inaccuracies and wasted work.

To help everyone with accurate setting of the the X, Y, and Z axis, I made a thing:

The front of the plate, looking down on a test piece of wood for calibration

The front of the plate, looking down on a test piece of wood for calibration

This is an aluminum plate that is milled to be as precise as I could make it (read: probably a lot of room for improvement) where it sits on the lower left hand corner of the piece to be cut, with the corner of the work sitting directly in the middle of the circle.

Side view of the plate

With the piece placed on the work, the cable is plugged into the back (I had originally drilled two holes on the front left and bottom of the plate, forgetting that is where the bit has to touch so as to not push the plate off the work, so I drilled a new hold on the back and wrote “Do not use this hole” on the other two) and attached via the alligator clips (ToDo: make a better cable) to the Z plate.

The cable connects the XYZ plate to the Z plate that comes with the Shopbot for finding the Z axis.

The cable connects the XYZ plate to the Z plate that comes with the Shopbot for finding the Z axis.

The user should position the bit somewhere over the top part of the plate, where doesn’t matter. The user loads xyz-zero-finder.sbp (the code is available at this GitHub repository) into the ShopBot software and runs it. Assuming the bit is somewhere over the top, it will then slowly move the bit down until it touches the top, at which point it will move to the side (visually this appears to be moving towards the front of the machine, but in reality the side of the machine with the power switch is technically the bottom, or X axis). The program will move the bit inside the circle at what it believes is exactly 0,0,0 and, after displaying a message, will move the bit up two inches to allow the user to remove the plate and put it away.

The bit at the corner of the work after the plate has been removed and the bit put back to 0

The plate is in the drawer under the ShopBot in the Arduino box (ToDo: Make a real box for the plate). Feel free to use it and report back how it worked for you, so that we can make it better.

I want to thank Dean, Everett and Todd for giving me valuable advice about how to mill the plate on the Bridgeport; it was tricky because both sides of the plate are milled and getting it to sit properly in the vice was very worrying to me. I also want to thank Eric for suggesting the project in the first place.

Culture Night 2015 @ TOG

Culture Night 2015 programme 269 x 361


Last year was our first Culture Night opening, and was one of our busiest days of the year (possibly due in part to us being unknowingly featured in the Irish Times)

For 2015 we want to make it better again!

All our groups – electronics, lockpicking, coding, crafting and craft-beering have flourished over the last 12 months, and new groups such as CAD and art have taken off.

We have made loads of projects and aquired great new equipment that we are eager to show off.

DSC_1201 3hex DSC_0104

So please join us! For 5 mins or 5 hours :)

All welcome no matter what the weather, we will have all kinds of crazy technology and projects to show off, with tours, demos and tasters throughout the night.


And remember: we have the synchronous hackathon and pizza night the next day!

Stop over Saturday for a scrumptious open social :)
