Bringing a Cracked Flymo Back to Life

With summer on the way, you might be thinking about cutting the grass again and dragging the lawnmower back out of the shed.

This Flymo Easi Glide 330 came into TOG on a Tuesday night with a fairly serious problem. The outer case was badly cracked. It was manufactured back in February 2014, so it has clearly done a good bit of work over the years, but this kind of damage could easily make you think it was ready for the bin.

But what do you do with a crack like that?

Glue was never going to be enough here. The plastic casing takes a lot of stress and vibration in normal use, so this needed something stronger. Out came the plastic welder, with our member Ambrose taking on the repair.

A tool like this works by heating the plastic and embedding metal staples or pins across the crack. These act like reinforcement inside the case, giving the repair strength and helping bridge the gap where the plastic had split. As you can see from the photos, this one needed quite a few of them.

The nice thing about this repair is that Ambrose was able to do all the work from the inside. That means the outside still looks great, while the inside now has the strength it needs to keep going.

It is a lovely example of the kind of repair that becomes very straightforward when you have the right tool and the right knowledge. That is one of the great things about a hackerspace like TOG. We have a wide range of shared tools, but just as importantly, we have people around who know what tool to reach for and are happy to help figure things out.

This was all done on a normal Tuesday open night at TOG. If you have a project of your own, something that needs fixing, or you are just curious to see what goes on in the space, Tuesday night is a great time to drop in.

TOG at HamCon Belgium 2026

TOG is heading to Belgium next month for HamCon Belgium 2026, a day packed with talks, workshops, demos, and plenty of radio chat.

Our own Jeffrey Roe EI7IRB will be part of the programme with two sessions on the day. He’ll be running a Satellite Ground Station Workshop, showing people how to build and get started with a TinyGS setup, and later giving a DMR Workshop for anyone curious about digital radio and how to get on the air.

It looks like a great event, with talks and activities covering everything from TETRA and DAPNET to meteor science, antennas, PCB design, and more. If you’re into amateur radio, digital modes, satellites, or radio tech in general, there’s loads to dig into.

If you’re thinking of making the trip, have a look at the full programme and event details here: https://hamcon.be/

*** *** Cancelled *****🚴🧩 Cycles, Clues & Making: A Bike Treasure Hunt for Bike Week

We’re sorry to let you know that we have had to cancel our Bike Week event.

This is due to volunteer availability and logistics on the day. We are a volunteer-run space, and we do not want to go ahead with the event unless we can run it properly, safely, and give everyone a good experience.

We’re sorry for the short notice and for any inconvenience caused.

The good news is that we still have another Bike Week event going ahead at Tog:

🚴🔧 Bicycle Maintenance & Advice Meetup
Saturday 16th May
From 15:00
https://www.tog.ie/2026/05/%f0%9f%9a%b4%f0%9f%94%a7-bicycle-maintenance-advice-meetup-for-bike-week/

You are very welcome to come along to that instead. It will be a relaxed afternoon of bicycle maintenance, advice, and hands-on help from the Tog community.

Thanks for your understanding, and apologies again.

We love making games. Some of our members love cycling. So naturally, we asked: why not combine the two?

As part of Bike Week, we’re running a Bike Treasure Hunt — a relaxed, playful evening where you’ll cycle a short route and solve puzzles along the way.

🗓️ When

Friday 15th May, 19:00
Duration: 2 hours

🎟️ Grab your free ticket here:
https://www.eventbrite.ie/e/cycles-clues-making-a-bike-treasure-hunt-for-bike-week-tickets-1987656652554?aff=oddtdtcreator

🗺️ What to expect

This is a ~5km looped cycle starting and ending at TOG, taking in the canal, a local park, and nearby roads. The route is designed to be accessible and low-pressure, using canal paths, park spaces, and quiet streets.

Along the way, you’ll encounter four checkpoints, each with a small challenge:

  • puzzles to solve
  • things to spot
  • simple hands-on making

Complete them all and make your way back to TOG for some food and a chance to chat, compare notes, and see how everyone got on.

👥 Who is it for?

  • Individuals or teams (if you’re on a team, just have everyone grab a ticket)
  • Families welcome (children should be accompanied)
  • Beginners welcome

You’ll need a bike to take part, and you’ll be cycling on open roads as part of the route.

🚴 Bike Week

This event is part of Bike Week Dublin and is supported by Dublin City Council.

If this sounds like your kind of thing, there’s plenty more happening across the city — have a look at the full Bike Week programme:

💬 Final note

This is a bit of an experiment — a mix of cycling, games, and making. It’s meant to be fun, social, and a little bit different.

Come along, bring a bike, and see how you get on.

Toilets on the Air at 39C3 (TOTA)

You might have heard of Parks on the Air (POTA), Summits on the Air, or maybe even Bunkers on the Air. Radio amateurs love combining the hobby with an excuse to go and visit somewhere.

But what about Toilets on the Air?

Yes. Toilets.

Let me set the scene

Picture this: around 16,000 people in Hamburg, Germany, all packed into a massive conference centre for the 39th Chaos Communication Congress (39C3), a four-day hacker conference running 27–30 December 2025.

It’s the middle of winter. The venue is huge. There’s reinforced concrete everywhere. You can be walking for ages just trying to get from one hall to another… and if you have a handheld radio in your pocket, you’ll start wondering how well anything is going to get through all that building.

Which brings us to…

TOTA — Toilets on the Air

TOTA is a small (and slightly ridiculous) activity that’s been running at 39C3 for a few years now. The idea is simple: it’s a gentle “contest” / training exercise to help new radio amateurs (and anyone curious) learn basic operating. https://totawatch.de/

And don’t worry, you’re not asked to make contacts from inside the toilet itself. The rules are pretty clear: stand a few metres from the door, don’t block anyone, and always respect privacy.

It’s meant to be good fun, not weird.

Modes

  • FM: 430.200 MHz
  • SSTV: 430.200 MHz
  • CW: 432.032 MHz
  • DMR: Brandmeister TG26223

Activators, Hunters, and T2T

Like the other “on the air” things, you’ve got:

  • Activator — the person at the reference (in this case, a toilet location) who calls CQ.
  • Hunter / Chaser — the person answering.

And then there’s Toilet-to-Toilet (T2T), when two activators manage to work on each other while both are at their own reference locations. Ridiculous, maybe.

My bit of TOTA (DL/EI7IRB)

I was busy giving three workshops during the first few days of the congress, so I only got in on the action on the last day.

I took on the role of a hunter, answering plenty of calls as I wandered around the conference with my Quansheng.

But only making voice contacts… where’s the fun in that?

Of course, there was SSTV.

So there I was, operating as DL/EI7IRB, with a handheld radio and a smartphone held up to the speaker, trying to decode images from the tones. It’s a very “CCC” way of doing it with minimal setup, lots of messing, and it somehow kind of works.

There’s a Mastodon bot collecting the SSTV images people received during the event. If you want to go down the rabbit hole and see loads of them, here’s the link:

Closing Thoughts

I was nowhere near the top of the leaderboard, but I had a great time. TOTA isn’t really about big numbers or fancy stations. It’s about getting people comfortable on the air, having a laugh, and learning a few things without anyone taking it too seriously. Maybe you will see TOTA at the next conference you go to.

Repair Club: Lamps Edition – Shedding a Little Light on Lamp Repair

We are trying something a little different at TOG with a new event format we are calling Repair Club.

Inspired by the work of Circular Square in Clonmel, this is a bit different from our usual Repair Café model. Instead of bringing along broken items for fixing, Repair Club is more like a focused class or workshop where we take one repair topic and explore it in more detail.

For our first session, we are starting with lamps.

We will be looking at common faults, how to test them safely, and some of the repairs you can carry out once you know what has gone wrong. That includes more than just the electrical side of things. We will also look at glueing, rewiring, testing, and the kind of practical fixes that often come up when bringing an old lamp back into use.

This event will be half class, half discussion, and half people standing around a lamp saying, “go on, try that there.” The idea is to share skills, compare notes, and build confidence around fixing things.

This is also a bit of an experiment for us. We want to see how this format works and whether it might become something we can repeat with other topics in future. There is no shortage of everyday objects that deserve their own repair night.

The event is taking place as part of Dublin Climate Action Week, which makes it a great fit. Repair is one of the simplest ways to reduce waste, keep useful things in use for longer, and help more people feel confident about understanding and maintaining the objects around them.

This session will be led by Jeffrey Roe, an engineer, maker, and long-time TOG member who has spent years running workshops, Repair Cafés, and hands-on events that help people build practical skills.

Event Details

Date: Thursday, 14 May
Time: 7:30 pm – 9:00 pm
Location: TOG Hackerspace
Cost: €5 via Eventbrite, with the fee going as a donation to TOG

https://www.eventbrite.ie/e/repair-club-lamps-edition-shedding-a-little-light-on-lamp-repair-tickets-1987020952157?aff=oddtdtcreator

If you are curious about repair, want to learn a bit more about fault-finding, or just fancy trying something new, this should be a good way to spend an evening at the space.

And if this goes well, we would love to run more Repair Clubs in future. If there is a repair topic you would like to see covered, or if you would like to lead one yourself, please let us know. There is always something worth taking apart, figuring out, and bringing back to life.

TOG heading to Shannon for the IRTS AGM Weekend

We’re packing up a few projects and heading west for the IRTS AGM Weekend in Shannon on Saturday 18th and Sunday 19th April.

This year’s 93rd AGM weekend is being hosted by the Limerick Clare Amateur Radio Club, and it looks like it will be a great weekend of radio, chats, workshops, technical talks, the rally, and of course, the AGM itself.

On Sunday, TOG Hackerspace will have a table at the rally where we’ll be showing off some projects from the hackerspace, chatting about what we get up to, and catching up with radio friends from around the country. If you’re around, please do drop over and say hello. We always enjoy talking radios, making, workshops, and the odd slightly mad project.

We’re also delighted to see TOG members Daniel McDowell EI8ICB and Ana Cañizares EI5IXB among the nominees for the IRTS committee in the upcoming AGM, with our own Jeffrey Roe EI7IRB standing for the role of President. TOG Hackerspace wishes them the very best, along with all of the other candidates putting themselves forward.

Because one radio outing in a weekend is never enough, a few of us will also be in Shannon on the Friday evening to try our first-ever Bunkers on the Air Ireland activation. The plan is to activate the Shannon Airport defence artillery sites B/EI-0151 and B/EI-0152.

EIBOTA is the Irish branch of WWBOTA, an amateur radio activity built around activating historic bunker sites, so it feels like a very fitting way to kick off the weekend. If you’d like to join us for the bunker activation on Friday, get in touch with us in advance. It would be great to have a few more people along for the fun.

It should be a lovely weekend all round, with a bit of portable operating, a bit of history, plenty of radio chat, and a chance to bring TOG on the road again. Fair play to the Limerick Clare Amateur Radio Club for hosting it, and we’re looking forward to seeing plenty of familiar faces in Shannon.

For the full weekend details, have a look at the official IRTS AGM page and the LCARC AGM weekend page.
