Group dynamics and interaction

On yesterday we had a good lecture about group dynamics and interaction. These are especially important things when it comes to projects like ours' which includes a lot of innovating and sharing of ideas. In our session we noticed that each group is unique and therefore has different group dynamics and interactions inside it. These can be affected for example with a positive atmosphere that encourages sharing of ideas and opinions and giving constructive feedback.

I have to say that our project has been very lucky getting a project group like us. In our group the ideas are shared with open mind and others opinions are respected. Somehow we've managed to bypass the usual "stormy" phase which can come after the group starts working together. I guess that our group has so positive and work-oriented people that we have a great chance to survive this sailing trip without storms and reefs, even though countering these shouldn't be afraid of. In terms of learning these situations are usually the best places to notice something new about yourself or others!


As Pedro mentioned earlier, the project's manufacturing phase is now going on. After yesterday it again seems that we will be able to have a haptic coin within our hands by the Easter-holiday, but let's not count our chickens before they are hatched...

The last week was exam week and we didn't have group meeting but I'm going to tell you some things about the last group meeting, the steering group meeting and the main events during these almost two weeks.

Firstly, we have accorded to change the working style. Now we are going to work in smaller groups and only some of use are focused in each part of the work. During the general meetings, held on Thuersdays yet, we are going to present to the other the advances made by each group during the last week, we are going to take the necessary decisions to the work of the next week and we are going to discuss the next meeting agenda.

Later, each group has explained their advances during the last week:
-Markko have told that the strontium aluminate applied as a paint is the most commun form to give phosphorescence to the objects. He would try to purchase the paint in a hobby store.
-Jani has explained that the best form to validate the coins is the current method based on the electromagnetic field of the metals.
-Antti has told that the self cleaning product is avaliable as a paint too and that it is able to be applied outwardly to the coin with whatever design or material.
-Heikki was the responsible of the transparent materials of the coin and he has stated that the best material is probably polycarbonate, despite of its poor wear resistance, because other polymers present problems like bad recyclibility and the ceramics are very fragile.
-I have spoken to the others about the metallic materials for our coin. We have accorded that the silver is maybe the best option due to its nice appearence and maleability and ductility. Another option, if the silver is too expensive could be cupronickel which is already used in manufacturing coins.
-Finally, Simo and Mirva have told us that the normal LED lights are the best option to our coin since they can work with a little amount of energy and because they are really cheap while the OLED light are expensive and hard to made. Simo showed us a nice product out of the LED's to see the brightness and we have accorded to put in the coin blue (and maybe white) LED lights which have around 200 mcd.

To close the meeting we have decided to make 2 different prototypes to the seminar in Mint, one of them with LED lights (scale 1:3) and another one without LED lights but with the correct final size.

The next day(Friday) we had the steering group meeting where we explained to the Mint guys and to the teachers all our progress and decisions. Tuoppi seems really excited with our design and he gave us some useful piece of advices.

Everything looks nice but during the week a big problem have emerged. Jani and Ari went to Mint to have a meeting with Tuoppi and one of the Mint's designers told Ari that the his design should be modified to be able to be manufactured, so the the manufacturing process can't start yet and we have only two weeks until the seminary!
By the other hand the paints to give to the coin phosphorescence and self-cleaning surface could e purchased soon. Tomorrow we have the group meeting, let's see how we work under pressure!

This week’s Thursday we faced the first big choices during our project. We had to decide that which ideas we came up during last month, were good and usable enough to implement in an actual concept coin. When we started to go through our ideas I think we were first a little too critical against our thoughts. Almost none of the ideas seemed useful. However, after we discussed and considered our most promising ideas for a while, we came up six great features that we are going to try to attach in our concept coin:

1. OLED / LED – light. Lights would give shining and standout appearance to the coin and make it easier to differentiate the coins from others. Lights might also go around the coin's outer circle so that the coin could also be used to follow time.
2. Validation of the coin based on the wave length of lights.
3. Glowing materials. Those materials are UV-active so the coin would shine in the dark after exposed to daylight. The coin might also be used to follow the amounts of UV-radiation, so you would know when it's time to leave the beach without burning your skin.
4. Self-cleaning surface. Based on our survey coins are considered to be dirty. This coating would ensure the cleanliness of the coin and make it even antibacterial.
5. Material selections. Middle part of the coin needs to be transparent that there is some use of the lights. Outer layer will be some metal alloy.
6. Form of the coin. Our design specialist Ari got a great idea about the outlook of the coin. It would be circle or slightly oval with eccentric transparent centre. This would provide fresh look to the coin and also ensure more use to the coin than just for trading.

Now we have finally gone through our planning face and are starting to make our ideas concrete in the form of the concept coin. In the end of the day I can say that if we’ll be able to attach the features above to our coin, the outcome will definitely be great!

Coin 2020 - Thinking About Your Coins

Project news – Decisions and more technology research

Last week we had the brainstorming session with the project group. We gathered a lot of nice ideas and chose the top ten ideas for technology study. In today’s meeting we compiled the results of the investigations together. It was time to decide what ideas really are respectable in coins and what ideas are possible, at least, essentially. After careful consideration we decided to discard some ideas, like Braille dot writing (small target group and being outdated), screen and sound in coins (proved too difficult with today’s technology and in this schedule). We will continue developing ideas of new coin materials, surface treatment with uncommon characteristics, electronics in coin, customization features and new additional applications for coins. Next week, we will decide what exactly we are beginning to develop – what is our suggestion for the coin of 2020.

Learning session - Expressing expertise

In today’s APD learning session we have nice subject. The aim was to learn about expressing own expertise. We used drawing as a learning method. Everyone drew own poster that illustrates their own expertise and other capabilities for project. After drawing everyone presented their own posters and oneself as an expert. Other group members added own comments and other noticed capabilities to the posters using post-its. Here you can view our posters. Images can be enlarged by clicking.

Brainstorming session

Hello everybody!
After visiting the Mint of Finland we had a very interesting brainstorming session with the group. It's not too common in Otaniemi to use brainstorming as a learning method but our industrial designer Ari taught us well. We all had to bring 3 or more pictures that inspired us. Pictures were about tecnological innovations or about something we held dear to our hearts. During the brainstorming we circuled the pictures around the table and tried to find new wild ideas about the coin of 2020. I think our brainstorming went wery well. We gathered a huge amount of ideas and it was quite easy to continue developing them.
When you are innovating, it's important to remember to accept all ideas. It was very hard for me at least to not to think about financial restrictions and things like that. Even the silliest ideas are welcome. It's only after the brainstorming, when we start to investigate the possibilities to make a coin from the idea.
We gathered ten of the most interesting ideas together and agreed to find information about them before next thursday. I'm really looking foward on that. It will be exciting to hear what new technologies to make a coin this group will find!
