A Real Jam

We’re big into our jams at TOG….. Linux, Python, Finish-a-thons… you name it. Last Saturday at our regular monthly Open Social, we ran a real jam… blackberry and apple to be precise!

With 3.2kg of blackberries collected from the Royal Canal in Dublin and Kildare, and apples from one of our members’ trees, we made a huge pot of jam which filled about 24 jars.

Our Open Social is usually a foodie affair anyway, with our pizza oven going. This one was especially busy with both the pizza and jam. Everyone got to have a stir of the pot, and we all got to take a jar home…. still piping hot.

If jam making and other foodie things interest you, get in touch. We might do another session soon. Check out our gallery for even more photos.

Fix All The Things

socks

If you follow Tog, you’ll know that we’re no stranger to Repair Café. It’s become a bit of an institution around here. We never know whats going to come in our door on the day. We’re probably well into 4 figures in terms of the number of items that we have fixed over the years. Repair Café also embeds a culture of repair in all those who get involved with them.

When is the last time you darned a pair of socks however? This is an easy fix, and probably one that most of us will have the means to do at home. Sadly however, we’re too inclined to just throw our old clothes away. This morning, we read that Ireland consumes more than double the European average of textiles.

These socks, bought on the Aran Island of Inisheer in 2024, were a bit too young and too nice to throw away. So out with the needle and thread, and in no time they’re good to go for another while. Now just need to keep those toenails trimmed!

Postcards

Every week we send a postcard to some hacker or maker space somewhere in the world.

We’ve interacted with many spaces over the years, and it’s a right of passage for our members to visit the local hacker space whenever they visit somewhere new.

Sure you can email, and there’s all manner of instant social media and messaging apps, but where is the fun in that! 

If you’d like a postcard from Dublin, let us know and we’ll add you to our list. Send us a postcard yourself!

TOG, Unit 1B Motor City, Kylemore Road, Dublin 12, D12 CF6V, Ireland.

8mm Cine Camera and Projector

Tog recently received a very kind donation of an 8mm movie Ciné camera, projector and other items. We still have all of our dark room equipment in the space, and several TOG members are still keen on film photography.

In the past, we have ran film photography workshops and processed film in the space. These formats are not dead. They still have a small but dedicated following. If film photography including Ciné and instant photography is something that interests you, why not drop in, see what we have, and have a chat with us. 

When we moved into our current space here in Bluebell, one of the very first pictures that we took on the day was an instant photo on an original 1970s vintage Polaroid SX70 camera that’s still working like new!

Capturing a Swarm…..

Bee Swarm

…..Of the beekeeping kind!

Beekeeping is one of the many and varied interests of TOG members. Our member John is a keen beekeeper, and he recently captured a swarm to create a new colony.

As the number of honeybees in a hive increases, the usual natural way to prevent overcrowding is by swarming.  A few scout bees will find a new location, and the old Queen will leave the hive with about two-thirds of the bees. They often cluster on a tree branch before settling into a new location.  

One way to catch a swarm is to put a box containing comb frames in a tree. Drops of lemongrass oil act as an attractant because they resemble the pheromone of a Queen bee. 

In this case, a swarm of honeybees have gathered under the box, rather than inside. These bees were removed by gloved hands and placed in the box. The Queen will start to lay eggs and establish a new hive. The bees remaining in the old queenless hive will raise a new virgin Queen who will fly out, get mated and return to lay eggs.

Taking some inspiration from our aquarium project in the space, John is planning a monitoring project for a hive, including some sensors and a camera to watch the bees remotely.

Aquarium Automation

Check out this cool aquarium project by our member Hussam. This is an aquaponics project called ”PIPONIC”. The system can be monitored and controlled remotely. Aquaponics combines fish and plants in one self-sustaining setup. In this case, the fish and plants are goldfish and mint.


The system runs on a Raspberry Pi 3, with a few key components:
• A light sensor that turns on LEDs in the dark
• A 12V water pump that cycles on/off to keep the water moving;
• A MAX31865 sensor that monitors water temperature for the fish (16–24°C);
The system logs data to a CSV file and sends it to Hussams website via an API for real-time monitoring. A camera connected to the Pi allows a visual check the water level.


You can view the live system status here https://hussamalhayek.com/aquaponics-status/
View the full code + WordPress integration and more details here https://github.com/Hussam424/Piponics


Hussam is currently working on automating the water level and would love to team up with others to explore new ways to expand the system and make it even more sustainable and smart. TOG has been the perfect place to experiment, learn and share creative ideas about projects like this. The aquarium is in our kitchen in the space. You can usually find Hussam at Electronics Night on Mondays. Feel free to drop by if you’d like to chat, share ideas, or collaborate on improving the system!
