I Love Creating Designing Prototyping

Evaluate project plan:

My original idea want to make a device to help people to memory or remind they where are there things. There are memory loss with elderly people. They had forgotten their glasses where is it and could not read the newspaper. They forgot to turn off the power for stove after cooking. Blablabla...... I want to make a knob. It can connect your phone and to set mode which you want to remind you and how long you want to use it. This is my original idea.

Last month my friends and me go to fishing, I decided another topic about my final project. I observed most of people could not to set a hook on the perfect timing. So lots of people loosing the chance to caught the fish. Another reason is, we have to keep our eyes fixed on the fishing float or rod all the time. It is very tired. The purpose of project is to help people to set a hook on the right time. I used Fusion360 to design fishing float.
I have done planning at week17 in the final project.

Apply time management techniques:

Its very hard to combine it and hard to print so I redesign structure of float.

After for long time to printout and combine it.

Then used Fusion360 to design fishing rod holder.

After for long time to printout.

I used Fusion360 to design fishing rod base platform for milling.

Looks great! After milling.

Put foam and pole to simulate putting fishing rod.

To design fishing sinker with molding and casting(week12).

To protect all of board, I used hot glue to protect them.

Then start to write program for software. I put ADXL345、RF433MHz transmitter、Battery、LEDs and Satsha kit into fishing float.

When the fish bite bait, the acceleration of gravity can be observed by ADXL345 then LED color will turn RED from Blue and send a signal to rod base via RF433MHz.

There are RF433MHz receiver、Battery、LEDs、Buzzer and Satsha kit on the rod base platform.

When the rod base received a signal from float the rod base LED color also change color to RED and can hear buzzer.

That is important news to info you that it is the perfect timing to set a hook.

Making Satsha kit and testing input device at week11. Testing output device at week13. Testing communication at week15.

I received Z-axis value from ADXL345 every second. So I used the difference between two value(this time and last time) larger threshold value then send a signal to rod base.

Trial and error is a fundamental method of solving problems or finding threshold. Finally I used 50 to judge fish bite the bait. It is very specific but not very sensitive.

Communication with float and rod base platform.

After software testing, then all components in assembly.

Here are some testing about trial and error for threshold videos.

when the ADXL345 detect acceleration then send a signal to rod base and chanhge LED color from Blue to Red.

Summarise and communicate the essence of a project.:

This is my final project for fabacademy2016. Will add mobile Apps for this devices in the future.
You can seeing fishing float situation on the mobile immediately.
Add log feature to record how many fishes you catch every month or every week.
