What we do

We are specialised in engineering and engineering management of innovative projects.

With our network of experts are are able to assemble teams of experts to best suit the project scope. We use modern tools and communication to maximise productivity. We can complete tasks in days or weeks that would traditionally take months.

The first prototype of the Python robot has been assembled! All systems are working. The robot can reach precise positions thanks to its stepper motors. While underway it can measure accelerations, battery voltage and current and write all the data to a log file on a micro SD card. Obstacles can be avoided thanks to a distance sensor mounted to the front. 

The next steps are to control the robot via WiFi and to add a camera so that it can execute spy missions. The extension headers for this are already on the board.

We are proud to announce a new exciting project! 

We are developing a micro controller based robot which is programmed via MicroPython. The aim is to teach kids micro controller programming. Billions of micro controllers are sold each year and they all need skilled software developers so that washing machines wash, airbags deploy and music players play music.

We selected MicroPython as the programming language because it makes programming very easy. All that is required is a text editor. The memory on the micro controller appears as a flash drive for saving Python files. This also makes loosing files very difficult.

The following things can be learned with the robot out of the box:

  • Switch lights on and off
  • Dim lights via PWM
  • Blink lights via timer interrupts
  • Read battery voltage and power consumption via an analogue to digital converter
  • Read button status via external interrupt
  • Operate the stepper motors
  • Communicate with the accelerometer via SPI bus
  • Program the accelerometer to create an interrupt
  • Store logging data on the SD card

The robot has been optimised for use by kids. There are no jumpers that can be lost and the reset switch can be disabled. We hope that the cost of the parts can be kept to approximately $25 to allow as many kids as possible access to the robot.

The interior of the Bondi 36 finally sparkles in snow white instead of carbon fibre black. The time span between the ‘before’ and ‘after’ picture is almost exactly 2 years. In this time the deck was bonded, the interior fit out completed and major equipment such as the engine installed. Countless hours were spent filling and sanding the surfaces and two layers of primer were applied to ensure the final appearance is perfect.


The Bondi 36 is a very advanced home building project carried out in Hamburg, Germany. The whole boat has been built using foam cores and carbon fibre skins with epoxy resin. Both deck skins as well as the hull outer skin were vacuum infused which is usually a technique reserved for the best professional yards. The whole yacht has been designed by KJ Engineering using 3D CAD software. As a result of this the built tolerances are around 1 mm. Such small tolerances ensure that all parts fit into the boat the first time without needing adjustment. This in turn speeds up the construction process significantly.

Launch of the Bondi 36 is scheduled during the European spring 2016.

We are pleased to announce the release of the Naval Architect Toolbox pro version. The pro version has all the features of the free version. Additionally hulls can be analysed automatically at a range of heel angles which is great for calculating the righting moment curve and finding the heel angle at minimum wetted surface area. 

It is possible to analyse quite complicated hulls such as multihulls and hulls with reverse chines. 

The pro version also makes it possible to calculate the mass of objects modeled in Rhino. Mass properties can be assigned to materials and the data is stored in the notes box of the regular Rhino material. It is possible to assign densities, area masses and point masses to materials. 

When calculating the mass the plug-in detects if the object is a solid object, surface or point automatically. The volume of solid objects is multiplied by the density, areas by the area mass and point objects simply have the point masses applied. 

Material properties can be assigned directly to the object or via the layer. The object material has precedence over the layer material and therefore it is possible to group objects with different properties into one layer.

Materials can be stored to files and imported which makes re-using of the data easy. A demo video is below.

The pro version can be purchased in our shop.

KJ Engineering Consulting is pleased to offer a new photorealistic image rendering service. The images are produced directly from 3D cad models and are ideal for presentations and marketing material. It is possible to show what the product will look like before a physical prototype has been manufactured. Different materials and colour schemes can be explored with the click of a button to explore design variations.

The render software allows manipulation of detailed camera settings such as lens length and aperture for depth of field control. Animations are rendered with motion blur depending on the shutter speed. 

Large objects can be modelled in a virtual photo studio to create dramatic light effects that would be difficult to achieve with the full scale product. 

Below are some samples of yacht concepts and our USB charger.
