This small project was an assignment for a free selection course at the "Hogeschool Rotterdam University of Applied Science". The goal of the course was to create a functional smart object which fitted certain requirements. I chose to build a smart webcam stand. The camera on top of the stand is supposed to turn in the direction where the users face resides (at that given time). If you'd like to reproduce this, please contact me so I can provide schematics, requirements and guidelines.
Step 1: Week 1
Brainstorming and researching.
Browsing the internet.
I've been quickly reviewing a few ideas for smar objects and I've come with the following ideas:
Smart Wake-Up (Lights up, vibrates, beeps softly).
Primary use: People that wake easily and don’t want to get scared to death when waking up.
Materials: RGB LED, rumble kit, piezo, microcontroller.
Smart keyboard (Lights up when a hand is detected and when it's dark).
Primary use: Lazy PC users.
Materials: RGB LED, light sensitivity sensor, proximity sensor, microcontroller.
Smart Camera, detects motion and rotates with the moving object.
Primary use: Tracking webcam.
Materials: Webcam, IR sensor array, microcontroller.
Flamespitting Halloween pumpkin/skull, spits fire upon detection.
Primary use: Decorational, not a toy!
Materials: Casing, mini gas tank, IR sensor array, microcontroller.
My definite project for this course shall be the smart camera!
Project Smart Camera
A movement tracking camera to be used as webcam with the help of IR sensors.
If a person gets up from his/her desk the camera is ought to follow the moving person.
This way someone can walk away from the computer.
Must have: a rotating USB Camera.
Should have: An IR sensor array.
Could have: Reset button.
Would have: Face detection or Flamethrower!
PS: Prototype attached in the picture.
Step 2: Week 2
Built a wooden frame from triplex using the laser cutter. And glued it together. I made a simple Adobe Illustrator SVG and "printed" it to the trojec laser cutter after aligning the laser head's height and adjusting the position of the triplex.
I'm afraid it will fall apart.
I used more proper wood glue within the grooves of the frame.
PS: Prototype in the picture.
Step 3: Week 3
I've made a schematic for the electronic circuit.
It's not tested yet.
A teacher on the fifth floor.
PS:Picture of schematic prototype.
Step 4: Week 4
Collected IR sensors and IR LEDs upstairs from my teacher. I hooked them up at home. And went tinkering with cables and the frame among other components.
I couldn't get the sensors to work properly.
Swapping the out with working ones and checking the resistors.
PS: Prototype in the picture.
Step 5: Week 5
I wrote a few lines of code in order to make the smart objects basic functions work.
Not really, general purpose debugging.
PS: Image of code, supplementing prototype.
Step 6: Week 6
Mounted all electronics to the frame. And tested the uploaded code. I've also reorganized the layout a little bit.
Some sensors where blocked.
I've tweaked the sensor positioning
PS: View the prototype video.
