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 elements express where some slight modifications were made. the model was then exported into a stl file and imported into 123d make from autodesk. this was then used to slice the model into layers. the layers were again exported into a pdf and imported into corel draw. there they were simplified and the inner volume was removed to save material. all the slices were then laser cut from poplar plywood. the layers were then glued together, sanded and the cracks were filled with a wood filling. over a simple vacuum table the car body was then formed with 1 mm petg sheets. since my oven is too small i had to split the model into front and rear sections.
the following pictures show some of the steps of the process:

the final result (sort of) can be seen here:

here is a video of the cars in action:

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 or not the settings are at an optimum or not.

quadcopter #5

this is my second foldable quadcopter.
since the first foldable quadcopter suffered heavily from vibrations the design had to be made much stiffer. this was achieved by increasing the diameter of the carbon rods, shortening of the rods and increasing the diameter of its body.
the design of the quadcopter can be found here.

the following video shows the quadcopter in action:

quadcopter #2

this is a very lightweight quadcopter made of carbon fiber tubes, glass fiber plates and 3d printed lugs to mount the motors. it is very agile and was actually the quadcopter with which i flew the first looping.
