Current Projects 2012

  • Autonomous Drone

    An autonomous process for detection of endpoints and transportation of objects.

    The project was centered around a flying drone and all the necessary components to produce a complete system which could operate all by itself. Resources from the mechatronics and electronics programmes were joined to make this project happen. Bachelors project ELE300 at UiA.

  • MakerBot Illustrations

    A graphical representation of the elektrical installation of a MakerBot 3D printer.

    The original diagrams to perform the setup of the elektronics on the Makerbot printers was lacking and I designed a new styled infographic like overview of all the connections.

Current Projects 2011

  • Sorting Robot

    An autonomic robot for sorting and delivering colored cubes

    The main objective of the project was to implement a robot which could be wirelessly controlled but operate by itself.

    By using a ATmega1280 microcontroller on an Arduino Mega as the central processing unit, a system was devised to autonomously follow a line and determine the appropriate operation based on detection of crossroads and endpoints. A light color sensor was used to sense the color of cubes in from of the robot. Course ELE212 at UiA.

  • LC Power Filter – FPV equipment

    A complete product for filtering noisy power sources by using a LC (coil+capacitor) low-pass filter.

    Targeted for FPV users (RC airplanes and quadcopters enthusiasts) this filter helps to keep the video stream from the video camera clean and distortion free. It is connected between the power source and the video system, isolating parts of the system from the noisy switching and drive train.

    PCB designed and manufactured, filters assemblies by hand. Sold in large quantities to vendors.

  • Robot Labyrinth

    A lab assignment to learn how to use a ATmega128, connected via serial cable, to solve a software labyrinth running in a Java simulator.

    The trick was to use the coordinates published by the simulator and interpret them in a meaningful way. Control signals could then be sent to the virtual robot to move it through the labyrinth in the shortest amount of time. Course ELE209 at UiA.

  • LED Bandwith Bar Meter

    A small project used to display the current utilization of the locally shared Internet connection. Updated very other second by the network gateway.

    A shell script talks to a Arduino-board installed with a ethernet shield, sending the download and upload values over to a second Arduino-board, where the values are scaled and shifted over SPI out to 64 shift-registers connected to a total of 128 LEDs. Mounted on plexiglas and powered by 5V 2.5A.

    Inspired by the cool fact that it’s possible to control each and every primary color on a long strip of RGB-lamps.

Projects 2010

  • FPGA Remote Controlled Vehicle
