Hackathon FAQ
What is a hackathon?
A hackathon is a 24 hour “invention marathon”. People meet, form teams, and hack on ideas together for 24 hours straight. All work submitted at the end must have been done during the hackathon. Additionally, sponsoring companies (and HackSussex itself) provide specific challenges teams can choose to work on to win particular prizes. These challenges are announced during the opening ceremony. You don’t need to be a professional, or experienced programmer to take part, as the event is open to all ability levels.
Who’s welcome at HackSussex

Hacksussex is a welcoming and relaxed atmosphere that invites any student. This includes anyone who has graduated within the last 12 months. An interest in technology is all you need. You don’t need to be studying Computer Science or be a programmer!

Due to venue limitations, HackSussex 2023 is 18+.

How do I get there?

Once in Brighton, you can get to campus by either train or bus.

By train: Falmer station is a short walk from the university and a few stops from Brighton on any line heading to Eastbourne, Hastings or Seaford.

By bus: Head to Old Steine and get the #25 bus towards Universities.

How will the virtual event work?

There will be a Twitch stream and discord channels opened before the event to allow for a great online experience! Although we will be doing everything to make the digital experience the best it can be, please note that online hackers may not be eligible for some benefits of the hackathon, such as food and physical "swag" items.

How long is the hack?

The hacking period itself is 24 hours, however, the event goes beyond that. Registration begins at 10 AM on Saturday, and the closing ceremony will complete at 5 PM on Sunday. Hacking hours are 12 PM to 12 PM Saturday to Sunday.

What do I need to bring?

All our hacker spots have dual monitor setups. That's right, everyone gets dual monitors! However, do not forget to bring either a display port or HDMI cable to plug in the monitors if you are bringing your own pc. Along with that, we recommend a few basic overnight hacking essentials such as: A laptop and charger, toiletries, sleeping bag/blanket, or anything else you want to hack on (like a Raspberry Pi or something).

Where can I sleep?

There will be a quiet dark room for hackers to get some rest in. We will have air mattresses however bring a sleeping bag and maybe a pillow. Sleeping won't always be comfortable, so you can always hack all night long.

How will I form a team?

You can form teams both before and during the hack. If you don’t have a team yet, don't worry! Our Discord channel will be open soon. There you can interact with potential team members, or just get to know other hackers before the day of the event. We're aiming to provide a very welcoming and comfortable event for everyone and are more than happy to help you find people you can hack with too.

The maximum number of people allowed in a team is 5.

What about food?

We will be serving 4 meals over the weekend free with your ticket. For any dietary requirements, make sure to indicate them during the registration process, or email us: contact@hacksussex.com.

Is the venue accessible?
