Viral Twitter Video

Jan. 2018

The accelerometer works and we have the first 2D fluid simulation. We put a video on the net which goes viral immediatly.
To this day the video has been clicked by millions of people and appears again and again in various forums, sites and video compilations.

First time on stage

First time on stage

Feb. 2018

At the Digital Night in Kempten, we present the Cube for the first time on a stage. In the online vote the crowd likes our project the most and we unexpectatly win the first place.

Mechanical development

Mechanical development

Feb. 2018

The development is progressing. Hannes works his way into Fusion 360 to construct the cube. A 3D printer is purchased to make prototyping easier. It runs day and night and produces countless parts which are then analyzed, improved, redesigned and printed again.

Software development

Software development

Feb. 2018

Adrian is tinkering with the software. He writes the basic framework and various classes that we will need again and again. By experimenting and implementing small ideas, new apps are constantly being created that simply look fascinating and are a lot of fun. When we finish programming a cube version of snake, we are too busy chasing each other over the cube, using small Bluetooth controllers, that work stops for several weeks :)

Batterypack V1.0

Batterypack V1.0

Feb. 2018

We develop an exchangable batterypack which can simply be slid into the Cube. With a total of 12 18650 cells, we achieve a runtime of roughly 10 hours (depending on the application, of course).

The hinge

Mar. 2018

Since the cube has to be opened to charge the battery, for example. We need a clever, beautiful, functional solution for this. Here Thomas helps by constructing a beautiful hinge. The pivot point lies exactly on the edge of the cube and closes the cube perfectly. To keep the lid closed we use small neodymium magnets just like in the first prototype.

Introduction Thomas

Introduction Thomas

Thomas and Hannes are longtime friends. Thomas is doing his PhD in the field of unmanned aerial systems for small payloads. The trained process engineer and graduated aerospace engineer is known for his "let's overengineer" style and therefore best suited for the construction of the hinge.

Bachelor's thesis

Bachelor's thesis

Apr. 2018

Adrian writes his thesis about the Cube. He develops the main operating system. The OS adds the possibility to easily add new apps. It also includes the menu with which it is now possible to select apps, display the battery level or adjust the brightness. He also develops another game, Brakeout 3D.

We have a graphic artist :)

May 2018

Matthias designs our new logo and takes the first steps towards our CI/CD. A first website is created, we make business cards and print t-shirts.

Introduction Matthias

Introduction Matthias

Like Thomas, Matze and Hannes know each other through paragliding and have been friends for quite some time. Matthias and Thomas are brothers. He is an excellent graphic artist, web designer and photographer. Full of ideas, creativity and enough craziness to join us.

Preparations for the gamescom

Jul. 2018

The cube structure is functional, the software is largely bug free (at least to the extent that you could use it) and the first small mass production starts. Reason: we will exhibit our cube at gamescom in August in cooperation with Kempten University. In total we build 6 cubes. To print all the parts for a single cube, the 3D printer runs for 72h straight. All wire harnesses have to be cut to length, soldered and crimped, Raspis have to be set up and configured.

The first serious Fail

Aug. 2018

With the hot temperatures of summer 2018 and the inefficient DCDC converters, quite high temperatures are generated inside the cubes. The PLA becomes soft and the heavy batterypack starts to push the Raspberry PI onto the other electronic components. Everything deforms, the cube gets gaps on the edges, the hinge doesn't work properly anymore. Our CNC milling machine helps us out. We replace the intermediate levels, the DCDC converter mounting plates and the hinge levers with aluminium parts. Not only does this make the Cube much less sensitive to heat, it also makes it much more stable.

Gamescom

Aug. 2018

With about 400.000 visitors, this is probably the largest event that we have ever exhibited at. Four of us go there, divide our time in shifts. We hang a cube from the ceiling so that four people can stand around and play snake. On a second cube, two people can always play breakout against each other. We promise everybody who could clear the complete field a cube, but sadly nobody managed to do so :D. Three more cubes are placed in a glass cabinet, partly on the corner on a turntable. It is an unforgettable week with an unbelievable number of enthusiastic people. We are rewarded with the, in 2018 newly introduced, "Best of Campus" Gamescom Award and are allowed to go on stage with all other winners for the award ceremony.

Creative discovery phase & David leaves the team

Creative discovery phase & David leaves the team

Sep. 2018

After all the trouble, we need a vacation. We go to the Atlantic Ocean for paragliding, relaxing, enjoying delicious wine and nothing to worry about.

David leaves the team. He is going abroad to write his Bachelors Thesis and wants to concentrate on his studies.

Thanks for everything, David. It was a great time with you on the team.

The press

Oct. 2018

The press has discovered the Cube. There are reports about us and interviews with us on radio, newspaper and television.

cirp

cirp

Nov. 2018

After a stressful year and our holidays, we don't really know where to go on from here. Our motivation to continue at all is a bit low. This changes as soon as we get to know Cirp. A company that specialises in prototype construction and small series. The company is located near Stuttgart and we go there for a meeting. Without big expectations and without a precise plan how they can or how they want to support us. What follows is a very interesting afternoon and evening full of discussions, talking shop, looking at samples, discussing how we could make the frame injection mouldable.

In the end it is clear that they want to support us in any case on our further way. Cirp saves the project, so to speak. A big thank you for that. Also a big thank you to Chris who initiated all this.

Development

Development

Nov. 2018

In the following weeks Hannes rebuilds the complete frame to make it injection mouldable. Cirp 3D sinters the prototypes and we refine them until we are satisfied.

At the same time Adrian designs our first circuit board. The kiss-fatherboard. Why the "keep it super simple" (kiss) is in the name, remains a mystery, even to us. We use a more efficient DCDC converter and put the H.Zeller-board directly on the board. The battery holders are now soldered directly on the board and therefore not removable. What we ourselves do not like too much and we know, sooner or later, we have to change that.

We are, for the second consecutive year, at the ccc with our cube. But this time we have registered an assembly and can display the cube and "work on it". To our joy we share our space with Esden, TNT and all the other cool people who work on their own cubes or at least on a FPGA to control the panels. We will also have to use a FPGA at some point. This will help to increase the fps to avoid streaks when photographing, just to name one optimization.

The ccc is again a complete success. People think the cube is great. We are now increasingly asked when the cube can be bought or what our plans for the future are.
