c30 rc car body (volvo c30)

the car body is still a work in progress. it is based on top, side and front views from volvo. they were used in blender to build a low poly 3d mesh of the car body. the smoothed mesh was then transferred to freecad, converted to a step file. this file was imported into creo […]

brushless gimbal brushless gimbal #1

this is the first brushless gimbal i designed and built. i hope it will be a useful add-on for filming. it should reduce the shakiness substantially. the gimbal relies on some of the cheapest components i could find for this project. adjusting the pid controller was a pain at first. i am still uncertain whether […]

multiwii quadcopter #8 quadcopter #8

flying near rivers and lakes always comes with a certain probability that a quadcopter crashes into the water, disappearing forever. while my designs are somewhat cheap, the loss of the camera and other equipment would still hurt. therefore i designed a quadcopter with a lot of buoyancy. the quadcopter consists of a 4 mm layer […]

multiwii quadcopter #7 quadcopter #7

this quadcopter has already gone through multiple design iterations. three of these made it into actual flying machines. the design plans for the first can be found here: the design plans for the second can be found here: the third is not yet on thingiverse. the following pictures show the various design iterations: […]

multiwii quadcopter #6 quadcopter #6

this is the first laser cut poplar plywood quadcopter. it is a very lightweight design having a takeoff weight of around 550 grams (including lipo 2s 2200mah). design by sini

scanner4 3d scanner #4

this 3d laser scanner is the most sophisticated system i have ever built. it features a calibration system to calibrate the camera and to find the laser relative to the camera, no matter how the laser was placed. the components of the system are the following: line laser with drive usb webcam calibration object control […]

scanner3 3d scanner #3

it seemed interesting to scan an object not just from one side but all around in one pass. a rotating table on which the object can be placed would do just fine. other than that this scanner is very similar to the 3d scanner #2. in order to improve capturing of dark surfaces i built […]

scanner2 3d scanner #2

my first 3d laser scanner was really just some kind of proof of concept device. therefore it’s a relatively simply setup with a usb camera, a stepper motor on which a line laser is mounted, a stepper motor controller and some software. it doesn’t use any kind of automatic calibration. the calibration is done for […]

scanner1 3d scanner #1

my first 3d scanner is a touch probe scanner that scans very accurately due to the very high resolution along each axis and a very fine touch probe. the scanner works very slowly. the reason is that the touch probe has to contact the object at every point of the x-y coordinate grid. some of […]
