To make the design document we divide the tasks over the group. Now I put al the documents together in the design document. This is the final result: DESIGN DOCUMENT
Making Design Document – Sprint 1
Raspberry Pi
Today we came to school with the following tasks: Establish serial communication with RPi and Arduino Use 2 ultrasonic sensors Test conductive paint I came to school and started up my Raspberry Pi, which I setup over the weekend, and started browsing for examples online. https://classes.engineering.wustl.edu/ese205/core/index.php?title=Serial_Communication_between_Raspberry_Pi_%26_Arduino This was the simplest and cleanest example I found....

second_ultrasonic_sensor_and_implementation
Theway that the ultrasonic sensor( a.k.a "Ping") works is the following - it sends and ultrasonic wave and then receives it back after it bounces off whatever is in front. Based on the time between the two events it can calculate on what distance the object is from you. Since our installation was supposed to... Continue Reading →
Design plan / construction drawings
In order to finish the design document, we needed a construction drawing, but the problem with this now that we know only estimate sizes, and nothing specific. So, I decided for now just make a rough sketch of the possible measurements of the one of the objects. At the second sprint we are planning to build a proper... Continue Reading →
Solving problems
Last night, we worked a bit more when we got home and tried on getting the ultrasonic and capacitive sensor to be read at the same time in arduino. We also wanted to get the values printed in processing, but we were getting an OutOfBounds array error and we decided to call it a night.... Continue Reading →
RPi, sensors ‘n’ more
Vasil and me headed to school today with the following 4 tasks in mind: Establish serial communication between the capacitive sensor and processing Use 2 ultrasonic sensors at the same time Start the design document Research how viable the switch to RPi & Python is I started working on installing raspbian on my RPi and...

ultrasonic_sensor_test
The IR sensor we used in the first prototype was good for start but it was time to level up. The range of the IR is only 1/2 of a meter at best and what we need was at least double that. The solution was the next thing on our morphological chart - an ultrasonic... Continue Reading →
Serial communication and prototyping the capacitive sensor
Today when I got home I decided to learn more about how the serial connection between arduino and processing works, so that I could just pass on the numbers from arduino to processing and then do all the work in processing. The most helpful online tutorials I found were the following: hooking up and code,... Continue Reading →
Building the prototype
As the sketches were approved, we, the builders team started working on the prototype.We decided to construct a smaller version of the installation, our measurements being: 10cm = 1m (in real life). To see the estimate scale of installation for materials we decided to go cheap and use cardboard. Firstly we started building the prototype... Continue Reading →
Retrospective first 2 weeks
Today we did the retrospective. It came out that everybody likes the concept. Also everyone can work on things they like to do. As negative point, we have to make decisions faster. In the first week we didn't come the up with a concept. The second week we have been more active and everybody worked... Continue Reading →
