This page describes the concept NWWC. Mainly NWWC are events held at our house and private garden, with friends.

Registration required. Email me at hkj @ kramse.o r g if you want to join.

The setting is much like BornHack but smaller of course. Code of conduct from Bornhack applies!


We are planning the following events:

NWWC-MARCH-2023 - Tuesday March 21. 15:00 - 19:00 - Frederikkevej 8-10, 2900 Hellerup - let me know in advance if coming.

I start the build-up around 14:00 and you are welcome to join around that time. When we finish I will ask you to pack up and leave in good order :-D.

It is NOT required to come the whole time, it is fine to drop by a few hours when you feel for it.

Registration needed, also if you just want to join a few hours!

What is it

An open space for people to be more social when hacking on whatever project they want. I typically work on projects that require more setup and focus than is available during daytime in normal work weeks.

Consider it a temporary hacker space where it is okay to bring your laptop, so you can hack and discuss tech while drinking tea, coffee, soda, beers, water, and eating snacks!


This time is is at KEA Frederikkevej 8-10, 2900 Hellerup - There is room for parking.


I work in network and security, both subjects that I find interesting. Both of these have new developments, new tools. Some which require effort to learn.

Sitting together accellerate learning, as you can ask a group of people at once, who know a good DNS library, and how to X. Quite often someone will know the answer.

Helping others, while learning a lot yourself.

So my projects often involve setting up a small infrastructure with networking, 10Gbit, firewalls, routing and routers - and then do some experiments.

I have a wide range of equipment like Juniper SRX, OpenBSD PF, Linux devices, Raspberry Pi's, switches, access-points etc. Ask me before you bring something heavy, I might have it already. :-D
