Spirograph on an oscilloscope

The French drawing game can be described mathematically and can be displayed with X/Y on an oscilloscope. With a web interface you can determine which figures appear

.zip

.zip is an artistic making space in Rotterdam and focuses on exploring digital culture, queer futures and alternative art forms. The space is managed by 8 artistic makers who actively fight to make the experimental use of tools and space more accessible to creative peers. Partly because of this, .zip has built a strong network of emerging artists from different disciplines and cities, who rely on the available space, tools and equipment. .zip independently programs knowledge-sharing programs for this network in which they and .zip members can participate, such as tool workshops, non-competitive hackathons and test days for interactive projects.

During HackFest we show what we are working on with a number of our self-built projects, which include: emerged from our workshops.

SoundForce Modular synths and MIDI controllers

SoundForce is independent synthesizer companies with product lines in Eurorack modules and MIDI controllers for software synths.

Wallieonline Mini Robot Games

Only Saturday

Wallieonline Mini robots based on an ESP32-C3 and the ESP-NOW protocol. We use these mini robots to get students excited about a technical education and a technical profession. By providing mini robot games at events in the region, we show how fun and versatile technology can be. To control the robot, we use the wireless ESP-NOW protocol from Espressif. ESP-NOW is a solution for situations that require both fast response times and a large range, while using the same frequency band as WiFi. The protocol is aimed at home automation and smart home, but also works as a wireless control for a mini robot.

Printstruments

Printstruments designs and makes musical instruments through 3D printing. I make them from biodegradable PLA. PLA, or Poly Lactic Acid, is a bioplastic made from fermented plant starch, usually from corn, sugar cane or tapioca.

The feedback I get from professional musicians is amazing. They are very surprised at the quality of sound and playability of the instruments.

Nerdy Gurdy

Nerdy Gurdy merges traditional musical instruments like Hurdy Gurdy (draailier) and Nyckelharpa with high-tech design and manufacturing. They have made these ancient instruments available for thousands of new musicians around the world, through lasercutting and 3d printing.

PaPloPerS

Once the bass starts thumping, the cornstarch comes to life. It begins to dance, undulate and take shapes that your eyes can hardly believe. Peaks and valleys appear and disappear in perfect harmony with the music. It is as if the bowl itself is breathing and moving to the rhythm of the beats.

WHY2025 DOME R&D + MISC

For the hackercamping WHY2025 I’m working on building a dome with an infinite mirror inside. I need the parts to be cost effective and modular for re-use at other events.

Dutch (home) computer history

Saturday 15:00

In the 1975s, history began for the home computer with the Altair 8800. 2 Years later 3 somewhat friendlier computers came on the market and from 1980 the use exploded, something that is still going on. Big brands that everyone knows like Apple, IBM, Commodore, Atari are the pioneers from the USA. Brands like Sinclair, Amstrad and Acorn were big and cheap in England. But where is Philips, Tulip, Holborn and Laser Computers? Historically, the Netherlands appears to have played a very large role in how computers are used. By diving deep into history as HomeComputerMuseum, the Netherlands appears to have been a major player in how the computer was used. Even the creation of the Internet is partly Dutch. In the 45-minute presentation, I’ll take you through why and how this is so.

Building your own ISP _or_ How to become sovereign on the internet

Sunday 11:00

In this talk, we’ll go over how the internet works behind the curtains. What it takes to set up your own ISP including IP-addresses, ASNs, routers and switches and why you might want to go on this journey yourself.

We use the internet every day, but few of us know how it works behind the curtains. Where does your ISP get its internet from? How does my YouTube video or that news article get to me?

Not only will you learn how the internet really works, you’ll also learn how you can build your own little island, not dependent on anyone! (at least, not one other network :)). Your own network, free to do whatever you want. You will get to learn about ASN’s, LIR’s, RIR’s, Transits and Internet Exchanges.

I will also give a tour of my own network and the journey I went on to build my own network. Hopefully, I will inspire you to do the same.

About Nick Bouwhuis

Hi! My name is Nick and I’m a Network Engineer at Speakup a leading communications provider located in Enschede. I’m passionate about technology and all things IT. I also run a small business on the side that helps small businesses in the area with IT-related tasks like management, security, networking and more. Networking and connecting certainly is something that really piques my interest. And I hope to transfer some of my enthusiasm in this field to you.

The live-bootstrap project

Sunday 12:00

In the past years a spend a lot of time analyzing the live-bootstrap project. Just this year there was an almost succesfull attempt to get a back-door in ssh which if succesful would have opened all Linux installations. Hackers with evil intentions and government spy organisations have an interest in getting back-doors into Linux. Another pathway is through a modified ‘binary’ of a compiler that, for example, inserts a similar back-door into ssh.
During the presentation, I want to talk about the risk of back-doors, why live-bootstrap is relevant, how it works, and what I have found along the route.

Hacking a magnetic lock: successes and failures

Sunday 13:00

When a hacker gets hold of magnetic locks from Enschede’s Ankerslot, how does he go about learning about it and how does he defeat it? Successes but also failures will be shared. Expect lockpicking, impressioning, arduino programming, soldering, CAD modelling, 3D printing and metal working.

About Walter Belgers

Introduction to Homie-IOT MQTT convention

Sunday 14:00

Are you tired of being locked into your All-in-One Home Automation solution? If you’ve ever transitioned from one to another you know the struggle (Fibaro, Homey, Home Assistant, Zipato, Domoticz, OpenHAB, or whatever else is out there…). Wouldn’t it be great if you can simply use the best mobile app, the best dashboard, and the best rules-engine, etc?

The Homie convention is an MQTT based convention that adds meaning to MQTT topics. Used by tinkerers and home-automation users to easily discover, describe, and interact with devices. MQTT + Homie becomes your own open message bus without being locked into all of the proprietary all-in-one tools.

About Thijs Schreijer

Thijs has been involved in IoT and Home Automation since the mid 90’s. He supported several standardization and open source efforts, as a member of the UPnP workgroup (the standard that powers MediaServers based on DLNA) and the late xPL project. He co-founded Hello-Niles, an early startup in Home-Automation services, and is now an admin at the Homie project. In his day job he is a solution architect/software engineer at Kong Inc which builds open-source API gateways and service-mesh technology.

Live & work without Google, Meta, Apple or Microsoft? It can be done!

Sunday 15:00

“Most people in the Netherlands are well familiar with the software applications and services of Google, Meta, Apple, Microsoft and other big-tech companies, among others.

You collaborate with your colleagues through Microsoft Teams. You app with Whatsapp from Meta via a Google Android phone or Apple’s iPhone with family & friends and you use Google Chrome, Apple Safari or Microsoft Edge to order something from a webshop. We have become hugely dependent on bigtech companies from countries outside Europe and that’s not okay.

But it can be done differently!

In this presentation, Björn Wijers discusses why bigtech is a problem and what options you already (still?) have to become less dependent on these companies. ”

Verifiable Computing Project – Building Truly Open Source Hardware

Sunday 16:00

Increasingly, what we call the processor on our computers and phones is actually a System on Chip (SoC) – that is to say, the processor is coupled with other elements such as integrated graphics, connectivity (ie PCIe) or other management functions. What do we really know about the hardware underlying modern computers?

Vulnerabilities found in subsystems such as those in the firmware of the Intel Management Engine (ME) found in most modern computers reveal a blunt truth – we have to trust, blindly or begrudgingly, that our chips are correctly implemented and without any backdoors, intentional or otherwise.

In this presentation, we take a look at how the hardware manufacturing ecosystem impacts the security of the devices we use. We also present a computer design whose processor is implemented in a FPGA (Field Programmable Gate Array) based on the open source RISC-V Instruction Set Architecture (ISA), as well as the toolkits available for synthesizing digital hardware.

Workshops

How to create youre one digital identity!

Saturday 13:00-14:00

In this workshop you will learn everything on biometric identity documents like your passport, identity card or driving license. How does the chip work inside it, why is it so secure and how can you check authenticity of it? Inverid Chief Scientist Martijn Oostdijk will explain the ins and outs of the ICAO 9303 standard underlying the documents. Thereafter Nick van Elk will explain how to check your own identity and how create a fake identity.
Please bring to the workshop a smartphone (for testing identity documents), an identity document (you can use one of our specimen documents if you prefer not to bring your own), and preferably a laptop to work on the datafile for your fake identity. Programming skills are not necessary but basic IT knowledge is required.
The Workshop is 45 minutes. Attendance is limited to 20 persons. Depending on the attendance the workshop might be in English.
