New “TogWeb” HF Antenna for EI0TOG

We have a shiny new addition to our amateur radio setup at Tog Hackerspace.

A huge thanks to Niall Donohue EI6HIB, from our friends in South Dublin Radio Club, for the generous donation of a cobweb antenna. In true Tog fashion, it has already been renamed the “TogWeb”.

Over the next few weeks we will be installing the TogWeb at the space and getting it tuned up for our HF station. The cobweb design gives us multi-band HF coverage in a compact footprint, which suits our city location nicely.

Once it is up in the air, it will:

  • Improve our HF receive and transmit performance
  • Give us more reliable contacts across Europe and beyond
  • Make it easier to demo HF to visitors during open nights and events

If you are interested in amateur radio, HF operation, or you are curious what all the wires and boxes are about, drop by the space on one of our open evenings. We are always happy to show people the station and talk radio.

We hope to log many more QSOs under our club callsign EI0TOG using the TogWeb. With a bit of luck, you might even end up in the log yourself.

Build Your Own Air Quality Sensor – Science Week Workshop

Friday, November 14th, 7:00 pm – 8:30 pm
Tog Hackerspace, Dublin 8
No experience needed — Ages 18+

Air pollution affects many people’s daily lives, not just those living near industrial centres. In Ireland, most official air quality monitoring is carried out using a limited number of government sensors spread across the country. As a result, we often rely on modelling to estimate current pollution levels. This can miss out on local or seasonal sources such as coal fires during winter or short-term event-based pollution.

In this hands-on Science Week workshop, we’ll explore how to measure local air pollution and take part in a global citizen science movement. You’ll build your own particulate matter (PM2.5) sensor system using a simple kit of off-the-shelf components. The device uses consumer-grade hardware to give a reasonable indication of local air quality — not as precise as professional lab equipment, but accurate enough to spot trends and patterns in your community.

The workshop introduces participants to IoT (Internet of Things) devices, data collection, and environmental monitoring. You’ll learn how to assemble the hardware, connect it to the network, and share your data online through the Sensor.Community platform — an open global network of more than 13,000 citizen-built sensors contributing over 10 million data entries worldwide.

By the end of the evening, you’ll have built your own working air quality sensor and joined a growing international community helping to better understand our environment through open data.

Come along, learn something new, and make a real contribution to citizen science this Science Week!

🎟 Tickets available via Eventbrite – €70 per person
This covers the cost of materials and includes a donation to Tog Hackerspace.

This is one of many events happening during Science Week.

Jeffrey Roe Named Reuse & Repair Champion at the Full Circle Awards 2025

We’re thrilled to share some amazing news from the repair community: our very own Jeffrey Roe has been awarded the title of Reuse & Repair Champion at the Full Circle Awards 2025 by Circular.ie.

The awards ceremony took place at the launch of Circular.ie in Lansdowne Road, and the judges had high praise for Jeffrey:

“Jeffrey has been the driving force behind Repair Cafés in Ireland and is a well-recognised champion and leader in the field. His community-driven, hands-on approach empowers people with valuable repair skills and fosters collaborative, social spaces for learning. Jeffrey stands out for his technical innovation and leadership in embedding repair culture within communities.”

This recognition highlights not just Jeffrey’s personal commitment, but also the incredible collective effort of everyone involved in running Repair Cafés at Tog Hackerspace and across Ireland. Every event is powered by volunteer fixers who bring their skills, patience, and community spirit to the table.

Over the years, Jeffrey has helped build and lead the Repair Café movement here at home while also sharing and exchanging knowledge abroad with Buinho in Portugal and FabLab Cuenca in Spain, among others. These international trips show that repair is always a two-way exchange: while Jeffrey brings experience and tools, he also returns with new ideas and approaches to share locally.

And the repair journey doesn’t stop here! Upcoming Repair Cafés:

  • 🔧 Tullamore – 11 October 2025
  • 🔧 Tog Hackerspace (Dublin) – 17 October 2025

Congratulations Jeffrey, and a massive thank you to all our fixers and visitors who make Repair Cafés possible. Here’s to keeping repair culture growing!

Radio Experiment Day at Tog Hackerspace – Tuning In to the ISS

As part of National Space Week, Tog Hackerspace in Dublin will be hosting a Radio Experiment Day on Sunday, October 5th, 2025, from 11:30 a.m. to 4:00 p.m.

This isn’t a class or formal demonstration — it’s a hands-on day of experimenting, tinkering, and learning together. The focus will be on trying out different ways to receive signals from the ARISS Slow Scan Television (SSTV) event taking place that weekend.

The Space Week SSTV Event, Series 29, will feature six images transmitted from the International Space Station (ISS) on 145.800 MHz (PD120 encoding). Two transmission windows are scheduled:

  • First Window: Oct 3–4, Start Fri 14:00 UTC, End Sat 10:00 UTC
  • Second Window: Oct 4–6, Start Sat 11:00 UTC, End Mon (time TBD)

The same set of images will be sent in both windows, so there will be plenty of opportunities to catch them. On the day, we’ll also be calling in to the Dublin-area IRTS news broadcast on 2M, with two especially good ISS passes around 1:00 p.m. and 3:00 p.m.

Everyone is encouraged to bring along their own radios, antennas, and setups — the more variety, the better! Feel free to just drop in, have a chat, and join the fun.

📍 Location: Tog Hackerspace, Unit 1B, Motorcity, Kylemore Rd, Dublin 12, D12 CF6V
🅿️ Lots of free parking available
🔗 More info: https://www.tog.ie

Come join us, meet fellow amateurs, and help us see just how many ISS images we can pull down from space!
