FABuslously Furry Synthesiser Module

Edwin Dertien will show his latest ‘invention’ the Furry Synthesiser module.

Robotic Creations by Yvo de Haas

Yvo de Haas is a maker that combines 3D printing, mechanics and electronics to make robotics projects, such as an automated board game, and a robotic tentacle.

Hackerspace TkkrLab

Hackerspace TkkrLab is a technology community in Enschede where you can practice self-development for technology. As a community they have their own tools for members like laser cutter, 3d printers and many electronic tools. During the HackFest they will show their Giant NES joystick

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

Home Computer Museum from Helmond shows a piece of history of (hobby) computers. They take a working Holborn computer (made in Hengelo in 1979) and other old/retro computers.

Firefly Zero

Firefly Zero is a modern open-source handheld game console with effortless multiplayer. It’s fun to play, alone or with friends, and easy to program.

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. For the same event I’m also working on LED disco flowers. Come and have a look at the prototyping process and have a chat. I’ll be prototyping fixing mylar sheets to the frames during the event: suggestions welcome!

DM Laser & Licht

DM Laser & Licht was founded officially in 2013 by Dimitri Modderman. We developed into a full service laser company, supplying bands, festivals and acts with all their laser needs. With roots in the hackerspace community we can also make custom projects involving lasers, laser mapping etc.

“The lazy nerd.”

Only Sunday

A closer look with “esp-now”

Error Instuments

Unique and experimental instruments that blur the lines between sound art and technology.
