Subject: Project 1 Weekly Memo 5

Dear Professor Michelson,

This memorandum outlines the latest progress of the team for the week. The progress is being discussed into three main topics below.

Achievements from Last Week

        From last week, bash scripting, email subject line and header, sending ADC voltage values to our email parts are successfully done. Also, after discussions we came out with several ways to calculate the wind speed. The ideas that we came out with are to use Hall Effect sensor, rotationary encoder and optical sensor. After the discussions, we have ordered all the components.

Progress for this week

       After receiving all the components we have tested them to come out with the best way to measure the wind speed. The fist, the optical sensor provides poor reaction time. Thus, we conclude that optical sensor will not be able to react to our hardware part which is pretty fast. Secondly, we figured out that we have to overcome too much friction force to spin the rotationary encoder. Therefore, we conclude that the encoder is not a appropriate way. Finally, we decide to use the hall effect sensor which provide us quite perfect reaction time and voltage graph.

Goals for Next Week

All the components are ready and demo-date is almost there thus, we will have to finish all the work. Also, since mechanical part of the project is not yet completed, we have to focus on building a wind-speed detector and temperature sensor.

Subject: Project 1 Weekly Memo 4

Dear Professor Michelson,

This memorandum outlines the latest progress of the team for the week. The progress is being discussed into three main topics below.

Achievements from Last Week

Over the last week, our team organized a meeting to discuss ideas in designing and building circuits for the hardware part of the project. We researched on different types of motors and sensors in order to obtain the suitable ones to be used in our design. We decided some mandatory components and drew circuits for our design.  On last Friday we have learned how to use PUTTY to run scripts, create email filter and check forwarding in the email. We also continued working on the code using the computer and the modem in the lab.

Progress for This Week

During this week, we have successfully completed bash scripting, email subject line and header and had the ADC voltage values sent to our email. The ADC circuit we built last week is used to measure the voltage values. The voltage value changes with different voltage input values and the range is set to be from zero volts to 3.5 volts. We also started building the hardware part of the project after our team discussed and choose the best design. Currently we are continuing working on the FFS and GSM and hopefully improve the time delay between sending signals to the satellite and receiving the emails in return. We also use Orbcomm commands and currently working on to combine FFS and email contents by modifying the code.

Goals for Next Week

As reading week commences, our team decided to meet in the lab to continue working on both the hardware and software parts of the project. We are still waiting for our ordered parts to arrive and hopefully they will arrive early next week. We will also be doing a lot of testing and calculations throughout the design process.

INTRODUCTION

This memo summarizes the status of the work that has been down this week, and also introduces the plan for the coming week.

ACHIEVEMENT FROM LAST WEEK

Our group has managed to send current voltage readings associated with exact time at the moment in proper format through emails. For the safety of messages, by using FFS commands, messages are saved to flash file memory while messages being sent to the satellite. Moreover, through ECE department, we placed our order of temperature sensors and DC motors which are necessary to the function of our project.

GOALS FOR NEXT WEEK

Firstly, we will try to finish what has not been done since previous weeks. Also, hopefully the parts we ordered will arrive next week, and we will start building up hardware part of the project.

Subject: Project 1 Weekly Memo 2

INTRODUCTION

This memo summarizes the completion status of last week’s goal and this week’s task. It also includes the plan for the next week.

LAST WEEK’S GOALS

We successfully sent the email using satellite, and modified ADC code last week. It was planned that we should be able to send voltage readings in the emails this week. The other minor remainder of last week was to change subject line of the email. The subject line was manually changed using PuTTY command window, but the ability to change it in C code remains to be explored. On January 29th, we used CFG_Write to change the configuration parameter which is related to the subject line of the message. After debugging several errors, we managed to change the subject line to what we need. On January 31st, we combined ADC code and ORBCOMM code to send voltage readings in the emails. A floating-point number was received by the email.

THIS WEEK’S TASKS

Due to the security reason and availability of the satellite, we need to save the messages in the flash before we send it. There are two ways to approach this, one using FFS, the other using ORBCOMM saving messages commands. The other objective of this week is to familiarize ourselves with the timer on board. Later on, we may need a timer to do timely event like saving data and sending messages.

NEXT WEEK’S GOALS

First, use timer to send emails with ADC voltage readings regularly. Second, create an OSI packet, save it on board, and send it. Third, save the packet which contains voltage readings on board, and send it.
