Repair Cafe – Vanmoof S3 Dead Battery

At one of our Repair Cafes, we had an electrical bicycle that would not turn on because it had been sitting idle for three months and would not charge. Vanmoof has no repair options since they have gone bankrupt over the last few months and not supplying any spare parts.

With nothing to lose, we started to take the bicycle apart to find out what it’s made of and if it’s serviceable. With little or no documentation on how to take it apart and without specialised tools and security bits we cracked it open.

Issue 1: Unlock The Bicycle

The bicycle needed an app to unlock it, the bicycle would turn on for 1-2 seconds and then turn off. To solve this I used a generic 36v charger and plugged it in to get the smart cartridge to boot up. This allows you to unlock your bicycle and ride as a push bike.

Issue 2: Repairing The Battery – Manual Recharge

The bicycle was not holding any charge in the battery. The battery is located in the bottom rale. You need a specialised tool to remove the wheel however I found if you deflate the wheel and take out 2 bottom screws you can slide the battery out. There was no power coming out of either the charge ports or discharge ports. By connecting the DC benchtop power supply to discharge ports battery started to charge. Voltage when plugged in was 28v. I let it charge up to 36v and then put the battery back into the bicycle.


The Vanmoof bicycle is back up and running and fully functional again. It was well worth the time.

Thanks to all TOG members who helped out with advice, I am in no way an expert on this.

This repair was carried out by Christian Kortenhorst.

Circular Economy Conference 2023

The EPA’s national Circular Economy Conference will be held at the Aviva Stadium on 27 September. This hybrid event will be an opportunity to learn about recent developments in the circular economy and the opportunities and challenges in implementing a circular economy in Ireland.

Our own Jeffrey Roe will be speaking at the conference in the afternoon session on Local Circular Solutions. Jeffrey will be covering the work and the impact of our Repair cafes.

Repair Cafes are community-driven initiatives that promote repair and reuse as essential components of a circular economy. Through these cafes, individuals can learn how to repair household items, electronics, and various other possessions, thereby extending their lifespan and reducing the environmental footprint associated with consumerism. Jeffrey will undoubtedly share inspiring stories and insights about how our Repair Cafes have not only contributed to waste reduction but have also fostered a sense of community and empowerment among participants.

Tog Harvest

As the summer comes to an end we wanted to share with you our member’s garden activities. We are not just interested in technology around here. Below are photos from our members on a range of different fruit and vegetables grown.

Lock Picking Without A Keyhole

One of our members came to lockpicking night with a problem. Their 1980s pride and joy motor had a passenger door locked. So easy to open? Well, there was also the problem that this door has no keyhole. Not wanting to break the lock and damage the car, the member took it to Conor the host of our lockpicking group night. After a little study and poking around with the mechanism, the door opened to many happy faces.

If you are interested in exploring the world of lockpicking, please drop by our bi-weekly Thursday night sessions.

Repair Cafe At Dublin Maker

Dublin Maker takes the form of a “show and tell” experience where inventors/makers sourced through an open call, will have an opportunity to showcase their creations in a carnival atmosphere. It is a family-friendly showcase of invention, creativity and resourcefulness, and a celebration of the maker movement. It’s a place where people show what they are making and share what they are learning. Makers range from tech enthusiasts to crafters, educators, tinkerers, hobbyists, engineers, artists, science clubs, students, authors and commercial exhibitors. They are of all ages and backgrounds, coming from all over Ireland and beyond.
Saturday 2nd of September 2023 10 am – 6 pm, Richmond Barracks, Inchicore, Dublin 8, D08 YY05

This year there will be over 40 exhibitors and we are one of them.

We are running a repair café – a community gathering place where people can bring their broken items, such as appliances, clothing, bicycles, or electronics, to be repaired by skilled volunteers for free. The idea behind repair cafes is to promote sustainability and reduce waste by encouraging people to repair and reuse their belongings instead of throwing them away. We regularly run a repair café in our own space in Bluebell, and we want to bring it to Dublin Maker to teach people about repair and promote a more sustainable lifestyle.

We will also show off some other projects that our members have made – for example, we are planning to have a hot air balloon, a light-up sculpture visualising network traffic, interactive games for visitors…

Community Support Fund

In a heartening stride towards fostering community enrichment and combating isolation, Tog Hackerspace has been awarded a one-off fund under the Department’s Community Enhancement Programme, overseen by the Dublin City Council. This grant comes as a resounding endorsement of Tog Hackerspace’s commitment to providing a safe haven for individuals of all walks of life to connect, create, and learn together. At its core, this grant will sustain our cherished free weekly open nights, amplifying their impact for the betterment of the community.

Empowering Connection: In a world where isolation can creep into the lives of the most vulnerable, Tog Hackerspace’s open nights stand as beacons of inclusion and togetherness. Our open nights have long served as a vital resource for those susceptible to feelings of isolation, including the elderly, the long-term unemployed, and new communities seeking a sense of belonging. Stepping beyond the confines of conventional leisure activities like sports or music, Tog Hackerspace provides a unique outlet for individuals drawn to the allure of creation and collaboration.

A Creative Haven: Tog Hackerspace is more than a venue; it’s a vibrant hub where passion meets purpose. As we stand on the cusp of an era where creativity and innovation are paramount, our space fills a niche that transcends the ordinary. It’s a space where people converge not to watch but to participate, where they delve into the art of making alongside kindred spirits. The grant will facilitate the continuation of these gatherings, ensuring that this haven for creative expression remains accessible to all.

The Heart of Peer-to-Peer Learning: At Tog Hackerspace, we believe that the truest form of learning is that which is shared. Our group nights, thoughtfully designed around an array of themes, encapsulate this ethos. Our approach champions a low barrier to entry, inviting anyone with a spark of curiosity to drop by and be part of something bigger. The peer-to-peer model we employ provides an environment where skills and knowledge are exchanged freely, bolstering a sense of community and empowerment.

Biweekly Rhythms of Connection: The grant’s impact will reverberate through our events, which operate on a biweekly cycle. These events serve as not just gatherings, but as touchpoints that foster ongoing relationships and collaborations. With the newfound resources at our disposal, we’re poised to elevate the quality of these experiences, ensuring that each gathering is a meaningful step towards building lasting connections.

As we look ahead to the months ahead, buoyed by the support of the Community Enhancement Programme and Dublin City Council, Tog Hackerspace stands ready to make a lasting difference. With the grant firmly in place, we’re poised to uphold the values of inclusivity, creativity, and shared knowledge. Tog Hackerspace’s open nights will continue to be a testament to the power of community-driven initiatives, where innovation flourishes and the joy of connection knows no bounds.
