Rebuilding an Ebike Battery

ebike-batteryA few of our members and visitors use Ebikes. We were presented with an Ebike battery which had a dead cell. The plan was to replace the cell with a new one. This is not ideal, since you end up with a mix of old and new cells, but the balance circuit should make it usable. On further investigation we found that there were a number of dead cells. So we set about rebuilding the whole battery with new 10Ah cells.

The cells are 10Ah LiFePO4 type…. 12 of them in all. The new ones are a little bigger than the old ones, so we will have to modify the case a bit, but that won’t be a show stopper. Drop in during our fortnightly electronics night to see the build in action.

Night of Talks, Undersea and Space Thursday 17th of November

As part of Science week, TOG will be having some events

We are privileged to be having a talk by Doctor Marc Ó Gríofa about his work with NASA, training astronauts in extreme environments simulating life on Mars and zero gravity on the International Space Station. Marc is a Physician, Scientist & Engineer along with being an expert dMarc O Griofaiver, and works to train astronauts while testing procedures, for future International Space Station and Mars missions.

Coming from County Meath, he now spends his days 19 meters below the sea in Florida.

 

His day job is part of the NASA Extreme Environment Mission Operations programme, or NEEMO, which evaluates tools and techniques being tested for future space exploration.

It does this by sending crew members to live in simulated spacecraft conditions and conduct simulated spacewalks outside of their undersea habitat. Spending weeks at a time they train and test procedures as if they were on Mars or in zero gravity.aquarius

There will also be a talk before hand by Daniel Cussen on receiving live video direct from the International Space station with cool videos, and Conor Forde on Cubesats & Space Commercialisation: Lowering the barrier to entry.

The event is open to all and free. No need to book. Try to arrive before 7:00pm on Thursday 17th of November 2016 as the talks will start at 7:00 sharp with Marc from 8pm to 9:30pm. There is free on street parking in the area. Be sure to give yourself time to find TOG. There will be time afterwards to take a tour of the hackerspace and see what we are all about.

One Year in Blackpitts

tog-locationThis October bank holiday weekend brings an important milestone for us.  It will be one year since we did the big move from Chancery Lane to Blackpitts. Over the bank holiday of 2015, we cleared out our old space and moved the lot to 22 Blackpitts, just a short distance away.

In the year since then, we’ve done incredible work.  TOG continues to grow. All of our old favourite theme evenings are up and running. We’ve built a fine common room, set up our kitchen, built classroom, electronics/laser cutter room and a general workshop. We’ve welcomed new members, each of whom bring their own unique skills and interests.

November will also be an important month for us as it will mark one year since we set up of our new organisation Tog Hackerspace Designated Activity Company.

 

 

 

Coder Girl Hack Day

shadow-boxesWe had a great time at Coder Girl Hack Day on Saturday. The girls assembled shadow boxes from laser cut plywood. They got to decorate them and install some LED lights that they soldered together with 9v battery and resistor. The boxes worked great and the girls got to take them home too.

TOG Brewday

Just completed our first triple brew day in TOG with 3 members making 75 liters of Stout, Brown Porter and American Pale ale.  Colm Gorey from Silicon Republic also dropped in to ask us a few questions about how to get started with brewing as part of his Tech Tips series.

Triple Brew Day

The beers were brewed on 3 very different types of equipment. the stout was brewed with the traditional mash tun and kettle combination. The mash tun is made from a large cooler box and the kettle is a very large boiler that is normally used for keeping water hot. The brown porter was brewed using a Braumeister, it is an automated brewing system that has the mashtun built into the kettle. The American pale ale was brewed on a semi automated brewing system called the Grainfather, it operates in a similar fashion to the Braumeister as it also integrates the mash tun and kettle together.

All of this equipment and ingredients is permanently located in the TOG space and is available for all full members to use anytime.

October Open Social

social-duckWe’re at it again. It’s our regular Open Social evening. If you’ve never been to our Social, you’ll find it a great alternative Saturday evening in town. Come in and look around. If you’ve never been in before, we’ll give you the grand tour of the space. Talk to members and visitors about projects or things you’d like to do. Ask about our regular craft evening, which has just restarted. If you like what you see, ask about joining as a full member. Either way, we’re always interested to know what has drawn you to our door.

Hopefully there’ll be, caint, ceol agus craic as usual. The space stays open until the last member is left……usually the small hours of Sunday morning. The evening is free to attend for members and visitors alike. No need to book…. just turn up. You can drop in for 10 minutes, or stay the whole night. We have parking available. Bring beer, food, gadgets! Our doors are open from 7PM. Hope to see you there.
