Homesense day #2 – light manipulator

During our last meeting, Darja confessed that she thought more about “doing” than “doing”.
Actually, she has so many ideas that I understand how difficult it is to make a choice. I’m having the same problem.

Anyway, we took a little time to discuss what she would like to do, where we should start and which project should be first on the list.
To sort the projects by interest and feasibility, we ranked the following parameters:

time : 1 long <---> short 5
tech : 1 hard <---> easy 5
cost : 1 expensive <---> cheap 5
kit exploitation : 1 null <---> lots 5
interest : 1 null <---> lots 5

Each project’s rank is found by simply adding up the values.

Project 1, Perfusion
Automatic watering for the poor plant. Maybe only mechanically.
Darja is very busy and sometimes she can’t water her plant for days. This is a project to keep the plant in a better shape.
time : 4
tech : 4
dollars : 3
kit exploitation : 4
Darja’s interest : 3
the techies interest : 3
average interest : 3
rank : 18

Project 2, Wall projector
Detecting presence and ambiant light to turn on a wall projection
Darja cannot drill anything in her walls, so she imagined projecting pictures or abstract movements with a pico projector and an old PC.
time : 2
tech : 2
cost : 1
kit exploitation : 1
Darja’s interest : 4
the techies interest : 4
average interest : 4
rank : 10

Project 3, IN->OUT communication (broadcast my life)
Use LED panels to broadcast to the outside events triggered from the inside
Something like : “I’m back home”, “My fridge is empty”, “I’m in this room”, etc.
time : 4
tech : 5
cost : 4
kit exploitation : 5
Darja’s interest : 5
the techies interest : 4
average interest : 22.5

Project 4, yet another alarm clock
Hijack iPhone SleepCycle to turn on a light or a water spray instead of alarm sound
time : 1
tech : 2
cost : 3
kit exploitation : 1
Darja’s interest : 2
the techies interest : 2
average interest : 2
rank : 9

Project 4.5,
Same project than project 4, but detecting the sleep cycle using an arduino instead of SleepCycle application
http://www.crunchgear.com/2008/08/01/arduino-sleep-tracker-diy/
http://www.flyingpudding.com/projects/sleep_tracker/
time : 2
tech : 2
cost : 4
kit exploitation : 3
Darja’s interest : 2
the techies interest : 2
average interest : 2
rank : 13

Project 5, My brain remained in the fridge (RIP)
Detecting every single piece of food in the kitchen, and its amount to automagically suggest recipes based on this information.
time : 1
tech : 1
cost : 1
kit exploitation : 3
Darja’s interest : 3
the techies interest : 3
average interest : 3
rank : 9

Projet 6, Rest In Peace
Noise detector for neighbors,:display current noise level through a vu-meter in the room
time : 5
tech : 5
cost : 5
kit exploitation : 4
interest Darja : 4
interest technik : 4
interests average : 4
rank : 23

The current project, light manipulator
depending on the light intensity, set a servo-motor to turn off the light after a specified delay
time : 5
tech : 5
cost : 5
kit exploitation : 4
interest Darja : 4
interest technik : 4
interests average : 4
rank : 23

The higher the rank, the better the interest/feasibility ratio.
So we first finished the current project, then next time we will start project n° 6.

Homesense

Tinkerlondon asked us if we would be interested in working on the homesense project.
They where looking for an expert in Geneva to help a household “play” with the homesense kit they made.
David and I accepted the challenge. We met with Darja. She has a smart and adorable household, and she has many ideas on how to transform her flat in a robotic nest. Of course, that makes her very interesting to us : )


Our first day was very entertaining and we had great pleasure meeting Georgina and Daniel from Tinkerlondon and Darja, our household.
