Electric Boat Motor

My diesel motor broke down, so I designed and installed  an electric motor drive.

Great about this project is the way I used different prototyping techniques to fab the timing pullys, and the alu frame.

And even more great is that compared to the diesel engine which had 4 separate liquid systems and electric system – this has just one electric system, and it doesn’t pollute or require any maintenance.

It charges on solar panels 20V boosted up to 60V for the 4x12v batteries (series) that provide the electric power. -I have even been sailing on sun alone 😉

V.1 10kW BLDC 150KV 45-52V 86Ah direct drive – not working 🙂

V.2 10kW BLDCmotor 150KV 45-52V 86Ah timing belt over cast pullys. Worked ok but at low rpm for the motor, causing high current draw.

V.2 25kW BLDC motor 50KV 45-52V 86Ah same timing belt setup, this works perfect from 150 w just driving the boat in harbour without current or strong wind up to approx 2000W in canals etc.

If you are interested in more details, just ask.

I will try to get some shots from the current installation.. to show the pulley setup.

 

Material and Detail 2015

The Master course Material and Detail was led by Daniel Norell, Jonas Lundberg, Kengo Skorick, HsengTai JaReng Lintner, Stefan Lintner and Stig Anton Nielsen. 28 master students were asked to propose a refugee shelter to be placed in the Zataari camp in Jordanien. Expanded polystyrene was the outset for exploring possible composite materials, and the winning concept focus on minimum material use. A secondary winner project was chosen for its multiple innovative solutions in joinery, composite thinking and fabrication techniques.

2015 Material Actuation – Addition Modification and Subtraction

SONY DSC

2015 Material Actuation, was part of introduction to the course Material and Detail at Chalmers University of Technology. During two weeks student teams investigated three modes of material actuation. Addition, four students constructed and tested an EPS extruder. Modification, four students constructed and tested a CNC metal-plate bender. Subtraction, four students constructed and tested a large scale CNC hotwire cutting system, able to cut EPS foam blocks up to 1200x1200x600mm. All projects made use of a large scale robotic arm. back

The MAKE:lab at Chalmers

20141108_Make02AMaterial Actuation and Kinetic Experimentation Laboratory at Chalmers was founded by Stig Anton Nielsen in September 2015 as a consequence of both the donation of a large industry robotic arm, and the funding for quality in education at Chalmers. The laboratory will provide the students and researchers with the opportunity to develop ideas on more advanced material explorations, based on actuator systems and sensor systems. So far one intense workshop has taken place during two weeks of October 2015.

Dermoid

CF035806

Dermoid In spring 2009 Prof. Mark Burry won the prestigious Velux Visiting Professorship Award to work with CITA, Centre for IT and Architecture at the Royal Danish Academy of Fine Arts, School of Architecture over a two year period. The aim for the Visiting Professorship was to explore how computation may lead to new material practices in architecture.
The installation Dermoid marks the culmination of this process. It simultaneously demonstrates the wealth of accumulated knowledge, design techniques and research methodology generated as a product of this international collaborative effort. Dermoid was unveiled in March 2011 as part of the “1:1 – Research by Design” exhibition at the School of Architecture.
Bottom: The deformation in the structure is investigated through laserscanning. The scanpoints are analysed via custom written code, recognizing connection points in the structure, these can then be used for comparison against the digital model. 2011

Distortion 2.0

CF035698

Distortion 2.0 Investigates how the specifications of geometry and materials can create sonic effects.
The project created new interfaces between acoustical science and the build environment by integrating the usually subsequent thought areas of sound performance, design and production. The research project introduced a customized design environment, computerbased acoustic simulation, parametric modelling techniques and the steering of high end materials and digital production technology.
The project challenges the way acoustics are generally thought. Where this is often either a narrow performance solution or even afterthought the project showcases a way to think and create sound and architecture at the same time. It explores the potential of multiple sonic parameters for their sonic effects and expands the usually used single criterion, reverberation time. New digital tools and techniques were developed to virtually experiment and test design propositions; physical experiments were completed to evaluate aspects of the design that could not be calculated digitally.
The dissemniation events gave the framework in which two spaces with specifically tuned acoustic performance could be created – seperated only by 15mm of material. Here the projects sonic and aesthetic sensations could be directly experienced and the performance was validated through modeling and simulation analyses used iteratively throughout the design process and through qualitative and quantitative analysis of the full-scale installation. 2010

Lamella Flock

cita_LamellaFLock2010_photoAndersIngvartsen__MG_0072

Lamella Flock investigates new possibilities of creating freeform structures in wood. Where this is at the moment achieved through the use of resource heavy production techniques using glue lam, complex joints, and 5-axis milling our research shows that freeform surface structures can be constructed by the use of straight beam elements. To achieve this we have utilized the principles of the traditional Zollinger lamella construction in combination with a non standardized production. Challenges arise from the complex interdependency of beam elements in the structure, and the non-linear relationship between requirements of structure, material and production. We propose an approach that utilizes principles of self-organization. This led to the development of generative digital tools that are informed by the physical 1:1 output including structural analysis, production and material knowledge. These constraints loop back into the structures geometrical setup.
Through the integration of this recursive feedback level the projects discussion is widened to the question how computational tools can help designers in the future to deal within an ever growing amount of complexity and integrate bottom-up design approaches. The project contributes to the future use of Wood as one of the few truly renewable building materials – in terms of both materiality and contemporary digital production process. Our research has shown that complex wood structures can be efficiently made and assembled using short straight beams. The key was the combination of traditional wood techniques with advanced computational methods. 2010

In this video the PID motor control is just implemented and un-calibrated. There is one for travelling up and another for travelling down on the lines. The robot travels between three xyz points in a test-loop.
