I(Åke) couldn't come to school yesterday or today, but I've remotely controlled a computer that was hooked up to our project to debug the software with the help of my dear team mates. Thank god for "TeamViewer" we couldn't have managed it without it (this is not a hidden advertisement, it is a totally open one)

Also we need to get the map ready - attach the circuits for the three gauge meters, lcd display, bus relays and turn button. Also we need decide which attachment points belong to which bus and wire them up. On the top side of the map we need to visualize rivers, add the cities and do some more "beautification".
The software can now handle all the output and input (with the exception of the power grid connection cord that isn't detectable yet). There is still some programming required for the game logic but hopefully it'll be finished in time.

Now we need to build the bus switching relay circuit and figure out why the demo program for the DS2408 is acting wierd when we try to use with the R/2R DAC connected to the gauge.
And do the main program...

The second photo shows the number of voltage after R/2R DAC and the after Opa.
1111 1111 4.80V -->1.93V
1111 0111 2.98V -->1.21V
Notes for the schematic:
- The OP-AMP has the wrong part nr, we use OPA337 but I couldn't find that one in Eagle.
- The relays also has a wrong part number.
- The circuit does not show that the site connectors also should have +5 and GND connected to the (only the 1-wire data cable, OW)
- The LCD display has the wrong part nr, but it follows the Hitachi HD44780 standard

The DS2408 data sheet recommend 470 Ohm instead of 220 Ohm in series with the LED Does it matter? Also the plug isn't exactly the one we use. The order on the 3.5 mm plug should be GND - OW - VCC counting from the plastic on the male plug to the tip of it.
And here is an idea of how to do the physical layout:
Tuesday, 6 April 2010
I found some documentation about storing device IDs in a XML-file along with classification and we'll probably use this since it's nice to keep that data out of the code. That way it's easy to keep track of what DS2408 is supposed to represent a factory, what is supposed to be a nuclear power plant and so on...
Next on the todo-list is to dwelve further into how to control the bits on the DS2408. Now the code alternates the state but I want to set the state instead. Also have to figure out how to read the input bit connected to the wire that can be connected to the main power grid (+5).
It all seems quite doable right now!

I don't think we can use this because of time constraints and the fact that we need three wires, not just two as they use, but it would have let us get rid of the 32 slot restriction and would look really cool!
One cannot detect where something is connected though, but we will solve that by dividing the bus into several spokes that can be connected and disconnected by means of a DS2408 that is a 8 port I/O port that drives 6 reed relays (will post a schematic for that later, but the basics is described here - see the switched network section). This way one can loop through the spokes and detect what is connected to each of them.
A new schematic for the powerplants and factories is displayed here. The IC DS2408 drives 5 LEDs and reads if the GRID-pin is connected to Vcc - in the game this is equivalent to connecting the power plant/factory to the main power grid, thereby getting or using power.
(The cities are actually wired the same way, they just don't have a plug, they are hard wired.)

We had our first usability test on 18th , 19th March with one kid and three participants in our group. During usability test we needed to test our first version of tangible Swedish map and game rules which is base on scenario.
All plants and factories were made with different shapes, colour, given cost value and producing/costing different amount of energy. We had to change numbers and values several time to figure out what is the best value. Only cities are fixed on map and there are lots of socket on the map where user can build power plants, and factories.
During usability test each participant try to reach to the goal that given by scenario.First usability test was with a kid and he enjoy the physical layer of the map and game. Only one participant reach to the given goal and others lose the game because lack of money.

- Moveable and having a tail
- Different plan produce different amount of energy.
- ON/OFF LED (symbolized that power plan is working)
- Wire with LED from Power plant to transformer. It lights according to how much current produces
- ON/OFF LED light up according to power plant. (light up at the same time / Blinking / Take a time to ON/ no lights (dead power plant)).
- Give a money value for each power plant.
- Need a Gauge meter to measure amount of electricity
- Only X number of connections can have one transformer
- How much energy got in.. show..
- Fix transformer Or moveable.. ????
- having male and female sockets. (connect to city/factory and connect to power plant)
- Fix city
- Small or Big city
- 1-5 LED(1st more lights - 5th less light
- Used energy
- Cost money and earn money
- how can we show Pollution stuff..
- amount of money left
- some animation about pollution

Date and time - 12-02-2009 from 12.30 - 13.30
Contact person - Eva Melin
Representatives - Andreas, Fanny, Yiwen, Yathika and Åke
Mathematics, Electricity, Music, Arts were the main area that we discussed. For the more information will publish near future.
Some picture from today field studies. Check group website for more pictures.
Just one example video.
I envision a physical "sim city", but with stuff like power plants of different types(Nuclear, water, solar, wind etc). They have different characteristics and drawbacks like different amount of power produced, different cost of electricity, different amounts of pollution, nuclear waste etc.
The power plants are connected by an electricity grid to houses and industry that uses the electricity. The more electricity is used the more power plants needs to be connected and the more pollution and other bad effects will appear.
This could be made as a model landscape with little powerplants and houses that you can connect to the power grid. There should also be a display or some other solution to indicate pollution and energy use.
The lessoned learned should be a better understanding for how electricity is generated and also what the effects are if we use a lot of it.
Another very different direction would be to explain generators that is the basis for all electricity generation and maybe show the similarity to electric motors. Also powering a generator with "muscle force" could give a sense of how much energy is needed to drive different things.
I had an idea for visualizing the sum of angles in 2D polygons. My idea is that you have physical "pucks" on a display that can detect the positions of them.
The pucks are connected by drawing lines on the display and the angles is displayed. Also the sum of the angles is calculated and displayed along with the name of the polygon. On the sketch I show four pucks, but you should be able to use any number of them from three to at least nine.
The idea is to visualize that the sum of the angles is the same in polygons with the same number of sides and also to show the sum of the angles for different types of polygons.
Maybe one should add something the student should do, like calculating the sum of angles, or some other better idea...
Another use for this basic platform would be to explore optics. If one used a different set of pucks like "spotlight", "mirror", "prism", "lens" etc one could simulate optics and add labels and explanations on the display.

Age : 7 years
School : one school in Bollnäs (grade 1)
Interview platform : Over the Skype video call
Extra : Eric has a own desktop computer with blue CPU and using it every single hours. I got some help from my cousin Jimutha to motivate him.
One day I called to him and asked what I want from he. So he got around one day to think and draw a picture. Next day when I had a Skype video call with him he explained like this.
The blue box is a computer box (I think he means CPU). It is having lotssss of lights. Specially purple and green. There are four small red boxes inside the computer. Each box has two vertical parallel lights. Still lots of lights See picture. Red line which is cross all red boxes is a power supply wire for all lights. Yellow lines on the picture also power wires. According to him there are lots of power supply wires but it is hard to draw all and it will make his picture ugly.
There is a door, left down on the the picture. According to Eric this door will works like a switch. When three persons, who are working inside the computer, enter in to computer through a the door, all lights will lighted. (So he means that door will work like a switch. When u press the key board or give some input computer will start to work). On the right hand side there will be a computer screen that he forgot to draw. All power wires are connected to screen so he can still see purple and green lights on screen. Persons who are working in computer has a own red box.He will work only in that area. He has a chair with wheel. So he doesn't need to walk. :)
Yesterday he explained about four box. He has four boxes for different applications. He told me he needs more red boxes but paper was too small. So yet another box he has four red box for Bolibompa, SVT Play, Facebook Barnbuddy game and his favourite computer game site.
Eric needs to explain more. But I think he got confuse by him self.

This is a "sound" project. Pressure sensors to create self induced sound and simulate walking on
different kinds of surfaces walking on grass, snow, glass.... Inpute sound will transmit to an Arduino controler(in a bag on shoulder) which simulate the sound.
There's a wireless technic called XBee. maybe we can think not only for this sound simulation. If you know the project been done in Ubiquitous computing - the Ikea light, they used XBee for changing lights remotely.
I like to create a project base on other projects' function which means that is possible to work with and fast to implement.
Inspiration from Sifting and the Pillow from Fardshid(assistant). Like reality, By mixing RGB to create new color. Here, we can pour "colour"s to the big plate, all of plates have display and direction sensors (implementable). There's one thing can not be done in reality, but probable could be done here in digital world: absorb one of the basic colour from the big plate. Touching the surface of the big plate by a "cube" could be one way, the longer time for touching the more absorbed. For getting colore, a "pen" can just touch the big plate. A "paper" is need too. One more thing, to empty the big plate, "pouring" the colour inside to anywhere.
Waiting for your opinions...

So I got some funny idea about making some interesting thing for kids. Can't we make some interactive globe for kids. Like when they touch one country they can see detail of selected country on a screen. This just quick thought. May be we can have more function. Kids can play and learn at the same time...

We today worked and finished our Process Proposal. We also discussed what we are interested with the goal to find a more specific question to work with. We ended up with these different things:
* Using an artifact with out help. (Åke)
* Education (Yathika)
* Play (Yathika)
* Challenge (Andreas)
* Complex concept explained to kids (Åke)
This lead me(Andreas) to think back on a discussion with a friend about the general knowledge of people. That in the future, all people should know how a computer works, what components it has etc. The concept of the computer. And that it should be taught to kids at an early age.
This got an discussion going, we ended up with a project idea:
"Teach how a computer works, what components build up the computer and how math is used in it, to kids."
This is one idea, we should not invest to much in to it, but it is something work with.

Our iterative work model will be split up into five iterations with different themes: Knowledge Building, Ideation, Prototype, Implementation and Evaluation.
Each iteration will have a duration of two weeks.
A iteration will start with a kick-off meeting on the first Monday, where the priority list will be constructed, the near future is planed, work and responsibilities are divided on the group.
Intermediate meeting on the second Monday of the iteration. Where the progress is discussed and the last week of the iteration is planed.
Evaluation meeting will be done on the last Friday of the two weeks. What have we done, what is our result? On this meeting we will produce an iteration rapport.
Every Thursday will have a work meeting, just to have a certain day you know everyone of the group is gathered just for the project.
Yathika will soon post the schedule for the iterations.
