Prototyping a self-watering flower pot

Last week we presented a group project for the course in Advanced Prototyping. Wanting to keep the plants alive for those having the standard “busy-week, got no time” was the inspiration for this self watering flower pot. We wanted to make this a waterfall where the calming sound also comes with the package. The prototype could be seen as a proof of concept, made in about 4 weeks. It utilizes an Arduino connected to a soil moisture sensor which will trigger the servo, which moves our acrylic tap over the planter box. However, this has many practical dead ends, ideally one should use a computer i.e. Raspberry Pi to log the data, and water this predictively. However, we are very happy with the result.

Reverse Engineering – Custom insoles

We did a pretty nice project for a course on prototyping, and I wanted to make a short breakdown of how this can be done. A short description that can serve as a rough guide.

Firstly, the equipment used: GoScan!, Rhino CAD software and an Ultimaker 3D printer.

By using the scanner we are able to obtain a cloud point (geometries) of our foot. This we want to extract this information in terms of curves. It is important to adjust the scanned foot to the correct angle along all axis first. We start then by marking an outline of the foot, and adding some vertical lines which will be the mesh we project on the foot. As seen in pictures 1-3 below. We need to offset the outline inwards to ensure we capture the foot when projecting lines. After we have obtained the projections, the curves can be extended beyond the foot’s outline. This ensure that a loft function can be used to generate a surface(picture 4). This surface is later trimmed by the original outline(picture 5), and we finish off with offsetting the surface to create a solid. Now we can fillet the edges, add some ventilation holes or initials.

TransferWise needs to work with Airbnb

Airbnb is a fairly known start-up. Making anyone a kind of hotelowner, providing a platform for short term rental of rooms, houses, apartments or castels. They are growing rappidly. Transferwise has also entered as fairly large, with Sir Richard Branson’s investing in them. Essentially a service that makes international money transfers “fair and cheap”, the simple solution saves money for people who do international money transfers at any scale. Watch how it works here. Typically, the bank will firstly make you pay a fixed fee depending on which country you are sending money to, then they will use an exchange rate that benefits the bank at a few percent charge. It all adds up, and is not very transparent.

However, why these two startups are not integrated with each other I hope is only a question of time. Because, as I recently used Airbnb for the first time I really missed the transparency of Transferwise. I was required to pay a sum in Euros with my Norwegian card. So consequently I was charged 3% comparing Airbnb’s rates with Transferwise. This adds up. So thinking aloud, I would like to see a future where Airbnb uses Transferwise to conduct its payments. Essentially it would require some reworking of how Airbnb does its authentication and cancellations. But there are clearly many benefits of partnering with each other.

Going on an adventure

Going on an adventure

My friend Sven Ekert and myself have outlined a plan for a 55 day trip through Europe. We recently marketed this on social media (FB&Twitter) and consequently were placed on the Staff Picks ( ) , we would like to share our idea here as well. Any amount of help (in financial means or in kind ) are much appreciated, we believe this trip is more than a summer break and invite you all to please take a look at our plan and aim here

Workload, or a load of work

Previous semester was a breeze, 3 exams, no biggie. Well that means only one thing work has piled up. Significantly. 

I am taking modules of my interest and therefore they happened to land on this semester. I will be taking:

  • Management 3
  • Renewable Energy Systems
  • Sustainable Development 
  • Advanced Production Processes 
  • Solids, Structures & Integrity 
  • Design 3 
  • Strategy

And of course writing my dissertation on the feasibility of shipping water, due to the on set of climate change and growth in NICs and LDCs. 

I have decided to work hard from the start, so I can attempt to finish my dissertation asap, to enable my coursework and labs to go well when they start. I am almost scared of the work, as I have AIESEC too, and will be planning parts of my Gap Year. 

Methods to learn is by devoting time to study consistently, and while i have a range of goals they all need planning and monitoring.


I think this will be a semester I will remember throughout my life, and week 1 of 12 has already finished. I can not believe im graduating on 18th July.
