Week 19 - Project Development
*Weeks Assignment*
complete your final project, tracking your progress:
* what tasks have been completed, and what tasks remain?
* what has worked? what hasn't?
* what questions need to be resolved?
* what will happen when?
* what have you learned?

In this weeks lecture Neils talked about that rapid protoyping with eagle and milling is faster then breadboarding. But it still takes me a day to finish a design and to mill a board and to solder it and program it some additioal. Most of the time I spend in eagle and then debugging the board. So I think I still need to get faster and find some tricks to make the process faster.

What tasks have been completed, and what tasks remain?
Update 28 June 2016:
I really want to improve my space invader but I believe I wont have time before leaving Barcelona to complete all the tasks I wanted to do. I want to continue design a smaller board and let it produce in China and do my workshop with it in China at Fab12.
Design and mill Hall Breakout v1Program Board v1Code for OLED Display in ArduinoAdd Condesator and Button v3Mill and solder board v3Design and mill Hall Breakout Double SidedDesign Housing3D Print Housingmake slidemake video- Design Mold for Housing
- Mold Housing
- make a smaller board version
- develop workshop for Fab12
- send board to be made in China
make a new Hall Sensor Break out board
optional: Raspberry Pi Zero HAT
- optional: add Bluetooth and Radio
- optional: Make a Light blue bean hat
What has worked? What hasn't?
Worked
- I2C
- the Oled Display
- the Code for measuring the speed
- the Code to display the speed on the Display
- the magnet on the wheel
- power over 5V
Not worked
- the position of the hall sensor
- the housing
- power over the coin cell battery
- power on 3V
- the position of the speedometer
What questions need to be resolved?
I still need to make the board smaller and figure out if I can run it on 3V with a coin battery. Also I need to test it once I have mounted if it can stand a crash.
What will happen when?
6 - 12 June: 1st Arduino Prototype Programming Interrupts, Attiny Board Design, Milling, Soldering, Desgining Interface, Programming
13 - 20 June: 3D Printing Case, Put everything together, Make Video
20 - 30 June: Design Small board for production in China, Mill Protoype
30 - 8 July: Finish Documenting
8 - 14 August: Finish Smaller design, Send Design to China, Develop Workshop
What have you learned?
I learned that I need do more complete prototypes quickly that work. I had one working board finished on the 12 of June and then I tried to improve the design to make it run on battery but I should have made a housing right away and thought about how to position the sensor on the axle.
