01 / About
A week in Coimbra
SemRede is a week-long event in Coimbra, bringing together people who care about offgrid communications, self-sufficient living and thriving communities.
Share knowledge, learn new skills, meet like-minded people and be part of a growing movement.
"Sem rede" is Portuguese for "no network": the moment your phone loses signal. This week is about what we can still do when that happens.

A working farm and learning space for a regenerative future. Five days of hands-on sessions, talks and time together.

Coimbra
One day, open to all: talks, demos, community fair, networking and celebration in the heart of Coimbra.
The week has no fixed programme. Saturday runs to times. See the schedule
03 / Showcase
Bring what
you built.
Building a radio, a mesh network, a solar setup, a garden? Write it up in the Showcase and ask for a stand. People vote on the proposals, and that decides who gets a table.
-
A table and a place to demo
Describe the project, what you need (space, power, a wall, quiet) and how many days you can be there.
-
A talk slot, if you want one
Say so in the same post. Other people can reply with questions and upvote the ones they want to hear.

Invited artist
Haleen
Haleen, a musical project by a Belgian couple based in off-grid Portugal, has crafted a distinctive genre inspired by their energy shift and consciousness transformation. Their music is described as mind-opening, hypnotic and uplifting, giving listeners courage and lifting their mood.
Hans started his musical journey at a young age, moving from the metal scene to an acoustic guitar tuned to 432Hz. Embracing electronic music, he blended diverse genres into a sound that crosses boundaries.
Kath had a rapid shift in musical taste, moving from mainstream hits to Electronic Dance Music, influenced by artists with a powerful energy. Her palette includes sounds from Sam Garrett, Mose, Peia, Yaima and Ajeet, mirroring her inner transformation.
They perform live, connecting with audiences through love and acceptance.
The songs are served from here, so listening costs you nothing but a page load. Plays only count for Haleen on Fountain, so go give them a listen there too.
Their page on Fountain05 / Tickets
200 tickets.
Free, and numbered.
SemRede costs nothing to attend, but there is food, water and space for 200 people and beds for 100, so entry is by ticket. Bring a sleeping bag in case there is no bed left for you. Ask for up to four, for you and whoever comes with you, and the numbered tickets arrive in your messages. No names, no email, no password: they are tied to the account this browser makes for you, and you show them at the entrance.

06 / Crypto
The grill takes
escudos.
Entry costs nothing, but on Saturday the meat and the drinks are paid in CryptoEscudos. It is a coin you mine yourself on your phone or your computer, so start before you travel: come with about 5000 CESC in your wallet.
07 / Chat
Talk before
you arrive.
Say hello before October, ask what to bring, sort out a ride, or find the people already working on what you care about. The room uses NOSTR, so your extension logs you straight in.
See you in Coimbra
