Work done as part of Wahlberg
Uni beams with tooth brackets as stationary part connected to scaffolding.
The stockings were fitted with an active wagon with a 550 W AC - motor and a passive wagon for stabilization.
All wagons were controlled using a DMX motor controller giving signals to a VDF.

Frame changing position and angle.
Canvas was mounted afterwards for projection of images.
The frame is made by aluminum and steel square tubing connected using larger square tubing with welded nuts attached
and bolts going through.
The hinges are made of square tubing welded on block housing bearing units.

Pop up restaurant in the woods wanted an alternative way to serve barbecue chicken.
Beams were hanging from the trees (with protection to not harm the trees)
Customer: ALTER 2023
For the opening ceremony of the ALTER Festival 2023, rolling banners were set up and programmed to roll down once
the music started.
Since the concert took place in a museum, very little time was allocated for setup and takedown.
The Wahlberg rolldowns were attached to the handrail using simple wooden mountings.
This drink-making machine was constructed from a variety of scavenged materials and repurposed pneumatic components,
serving as my final apprenticeship project.
The machine is powered by an Arduino MEGA, which precisely controls the system's functions.
The pneumatic system was salvaged from an old McDonald's fryer, giving new life to otherwise discarded parts.
The belt drive, an essential component for smooth operation, was recovered from a trash container behind a local
school.
I was part of the team that built the machinery for an Australian kinetic sculpture.
The sculpture features eight motorised loops, each rotating independently,
with each loop hoisting eight wires attached to curved rings.
The largest loop has a diameter of 4.5 meters, while the smallest is 1 meter in diamerter, all nested within each
other.

A client requested a rotating signpost for festival food stalls.
To achieve this, a tube was machined down to a diameter of 50 mm to fit into bearings that would keep it stable and
allow smooth rotation.
Next, a gear and motor were mounted to ensure the tube rotated at an RPM of approximately 1.
A slip ring and wiring were added to the tube, allowing for the integration of lights in the sign, making it both
functional and visually appealing.

For the scenography of the ALTER Festival 2024, I created a DMX-controlled chandelier.
The chandelier consists of an aluminum tube frame, held together by ratchet straps and suspended from the I-beams in
the ceiling.
The covers are made of thermo roofing cut to size, while DMX-controlled light strips were woven into the ratchet
straps, intertwined with fabric from other parts of the scenography.
Since it was DMX-controlled, it could be integrated into the stage lighting, enhancing the immersive experience of
the concerts.
