The Liberties Festival: How to Build Your Own Air Quality Sensor

Event posters. All information is covered in the text below.

Our own Jeffrey Roe will be hosting an Air Quality Sensor workshop as part of the Liberties Festival on Sunday 4th of September. We will be providing our soldering requirement to help out at this local community festival. Event details and booking information are below.

Join us for a workshop with Jeffrey Roe of Tog Hackerspace and learn how to build your own sensor to monitor air quality in your local area. 

Air pollution affects many people’s daily lives, not just close to industrial centres. Most governmental monitoring is only done with a very limited number of sensors across the whole of Ireland. Oftentimes we are relying on modelling to make the best guess at current levels. This can miss out on local/seasonal pollution sources like coal fires during the winter and event-based pollution. 

The workshop brings local people together to learn about the issues and gain hands-on experience. It opens up the world of smart/IoT devices to the general public but also contributes the data to a wider citizen science project, the Sensor Community. This network has over 13,000 sensors around the world with 10 million data entries. 

Jeffrey Roe is a software/hardware engineer working building public transport systems from bike-share schemes, to parking and port traffic access management systems. In his spare time, he likes to make crazy projects like bubble machines, bone conduction, IoT projects and anything with LEDs in it. A big fan of getting people making, he co-runs ‘Dublin Maker’ an annual maker showcase festival and Dublin’s Hackerspace Tog. He is also a member of Engineers Ireland, he currently serves as the chairperson of the Electronic and Computing division.

Buildroot Developers Meeting

We are happy to host the Buildroot developer days on September 17th & 18th.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation.

The Buildroot Developers meeting is a 2-day event for Buildroot developers and contributors. It allows Buildroot developers and contributors to discuss the hot topics in the Buildroot development, work on patches, and generally meet each other, facilitating further online discussions. Attending the event is free, after registration.

Visit to put down your registration.

Who can attend ?

This meeting is opened to all Buildroot users and developers. The event is free. However, we make it clear that it is not a training event about Buildroot aimed at newcomers. It is a meeting for Buildroot developers to make progress about various topics in Buildroot. It is recommended to already be a Buildroot contributor to participate to the event.

Hardware and Software Jam

We are having an informal electronics, hardware and software session on Saturday 20th August from 15:00 in the space. Nothing too serious or complicated. Just a few of us working on a selection of random projects and things that we want to finish. An excuse to come in and do something at a slow and leisurely pace.

You are welcome to drop in and join us. If you are working on something, bring it in. Or you can just drop in, hang out, get a tour of the space and see what we’re up to. There’ll be lots of tea, coffee and biscuits.

It’s the same day as our regular monthly Open Social which is from 7pm till late. So it will blend into that event from 7 pm and we’ll be hanging around for the whole evening.

Summer Green Thumbs

The summer is in full swing and our gardens and windows sills are full of life. Our community is made up of people with diverse interests and skills. It is not all computers and tech. Below are photos from our members what is growing at the moment.

Fresh potatoes ready for the pot.

Over 1kg of rhubarb ready to make something sweet.

A bee visiting some flowering artichoke.

The last of the loganberries with some rosemary photobombing.

Great use of awindow sill for some coriander, basil & chives.

And finally some shallow fry courgettes.
