Research Interests
Open Source Hardware
Started with Arduino and Reprap in 2012/2013. Admire the way the GNU project sets technical standards and brings together pieces of free software to form a more generally useful whole. Currently looking for a OSHW-project doing the same thing in practice. Interested in pursuing ideas like "Open Source Ecology" and "Open Source Economy" by creating appropriate technology and clusters of cooperating companies around them.
Since I'm a student of engineering physics, the use of OSHW in research and education is where my focus have been over the last two years.
Artificial intelligence
Especially reinforcement learning. My formal training has been within scientific computing, but my long term plan has always been to utilize it for writing free and generally useful artificial intelligence algorithms for robot-control and for reducing cognitive load induced by current computer user interfaces.
Programming and computation in general
Especially automatic generation of optimized assembly and the programming language Common Lisp.
Current Projects
Clerck, a RepRap hanging from the ceiling
Video 1: Here we see the first print ever finished by the hanging RepRap. The video tries to highlight error characteristics to facilitate future improvements.
Video 2: Here we see the first successfull first layer printed by the hanging RepRap.
Clerck is (by far) the world's cheapest 3D printer with a massive build volume.

2015: Feasibility study of resin-based 3D printing in a CDIO environment
More than 10 different low priced resin based 3D printers are hitting the market this autumn (2015). The market is young, and problems are plenty. This report describes a practical procedure to introduce a resin based 3D printer to a CDIO environment (Open Source Hardware lab).
My task was to:
- Write introduction text covering relevant technologies
- Minimize health risks and environmental damage
- Comply with Swedish work environment regulations
- Find practical utilization possibilities within university courses
- Ensure that both beginning and advanced users' preferences are considered
- Design all the needed usage routines
- Suggest a budget
- Suggest a printer

The project had it's own pilot study in spring 2015. This report was written in English: Media:Resin_report_pilot.pdf
Summer 2014: Started RepRap based limited company
Through the company I have delivered workshops for kids and prints. All work is documented GPL'ed and published (see blog posts [17], [18], [19], also see my Github user). We use open source hardware only.
Summer 2014: Sourced and built Reprappro Mendel
The printer and the build is described (is Swedish) Here. The build is described in English in a series of blog posts: [20], [21], [22], [23], [24], [25], [26]
2013 - 2014: Started Open Source Hardware Lab at the Physics Institution, Umeå University
Involved doing feasibility studies, marked studies, building several RepRaps, funding, purchasing tools, designing procedures, hosting workshops etc. The lab is now a active CDIO environment with ca 10 machines, exlusively Open Source Hardware. The work was unpaid and outside course activities, so I got a custom certificate as proof of work: Media:TL_intyg.pdf
2013: Graph database back end for mobile app
Team work during Accenture Summer Internship. App got 3000 users, but I was not allowed to open source it.
2013: Building a Printrbot+
This led to my initiative to start the 3d-lab at the Physics Institution at Umeå University. The printer is now dismantled, but it was called Sigrid, and is described here.
2013: Arduino-based Inertial Measurement Unit for use as an exercise aid
The unit used an Arduino mini board, an MPU-6050 (accelerometer + gyro) and a Bluetooth antennae together with code from the FreeIMU project. 
. Orderer was KriMag Techonology AB
In Media
- Article (Swedish) about the official initiation of the 3d-lab that I founded at Umeå University's physics department.
- Article (Norwegian) about how I sourced and built Reprappro Mendel during summer vacation. Started limited company around it, sold landscape models to local municipality.
