Prototype II Progress Report I Assignment

First Progress Reports for Prototype II go here.

Green Wu – Progress Report I for Prototype II: Bicycle-Powered Generator

Goals for the week:

Decide which battery pack we will want to use and purchase it as soon as possible.  Research charge controller and start working on the board design in Eagle. Research other DC or AC motor options.

Meeting times/dates

Meet on Friday after class

Individual Hours:

Alex: Spent an hour in the lab practicing uploading sketches and printing parts on MakerBot. Researched the battery control circuitry including thermal fuse

Stephen: Spent time researching electrical components (Battery, charge controller) for ideal setup.  Researched diagrams for future design attachments.

Adrian: Researched charge controller designs and motors for next design.

Eric: Researched python programming

What we did:

Researched the battery packs and purchased Duracell PowerPack 600HD. The power pack seemed to be the best option for it has an AC converter already built in, which saves us close to $300.  Battery pack will also serve to regulate the output and ensure continuous operation of electronic devices being powered.
Have done more research on the charge controller, found circuit diagrams for it and started looking at the list of components we need to make one.

What we didn’t do:

Didn’t start working on the Eagle board design yet.

Where we are stuck:

Still not sure what would be the best way to go about modifying bicycle pedals for hand operation. One idea is to check bicycle stores and see if they have anything we  can use.

Notes/Misc:

[MEDS] – Progress Report I for Prototype II: []

Goals for the week:

The goals this week are to figure out a way to input medicine data into the arduino.  Maybe buy a touch screen for the arduino. 

Meeting times/dates

Thursday for an hour, and Friday for an hour.

Individual Hours:

Fill this out by Thursday eve: Who put in what kind of hours for the week?

What we did:

Through more brainstorming, some of our design ideas have changed. One of the things discussed has been about inputting the medication data into the arduino. It was suggested that we use a touch screen for the input and output. We have decided that the touchscreen was a good solution to many of the problems or flaws that came with  the previous idea. We also searched for touchscreens that we could purchase.

What We Didnt Do: 

What we didnt do yet was buy a touchscreen.  Team safe wanted to make sure that we get the correct touchscreen, and to make sure that a touch screen would be beneficial to us even if we didnt  end up using it in our project. We do plan to meet on friday before the meeting to make sure we all want to purcahse it. Once decided,   we will purchase the touchscreen after the meeting on Friday, or on Saturday.

Where we are stuck:

Will a touchscreen be attainable for prototype two?   

Notes/Misc:

MAR – Progress Report I for Prototype II: Wireless GPS Tracker

Goals for the week:

* Start Upgrading the smart phone version.

* Studing and working on the android service program building.

* Troubleshooting the circuit issue of not showing up the bluetooth mac address.

Meeting times/dates

Friday 4 pm to 7 pm.

Sunday 4 pm to 7 pm.

Individual Hours:

Team members will work on their piece of work as needed.

What we did:

* We were able to follow up android service building. So far what we have tried is connecting an application with the service, but seems like building up a service itself running individually is effective than the method we are using now.

* We downloaded the  Froyo E-xtreme ROM for HTC G1 and G-Apps Add-on in to the computer to upgrade the android version of our smart phone. (Android 2.2 Froyo)

  •   We tried to program the SMID card (bluetooth dvice) with help form the instructor, but we could not. Itstill does not show the mac address, so we decid to buy another SIMD card.

What we didn’t do:

* We were unable to figure out the problem why our application does not call the service. So, as the next option we are building an android service to run itself without an application.

* We were unable to figure out the problem of why SMID module does not show the mac address.

Where we are stuck:

* Our SMID module seems broken and needs to order another one.

Notes/Misc:

Electric Chair – Progress Report I for Prototype II: Electric Chair

Goals for the week:

Analog to digital conversion

Joystick x,y, output voltages

Expand Arduino program for multiple output

Convert 12V system to 24V

Meeting times/dates

Thursday 7:00 PM – 9:00 PM

Individual Hours:

All team members put about an hour into research for the project. 

What we did:

We purchased arduino CAN BUS but at this point we may not use it. We met with Greg from CPRF and got a controller and joystick.  

What we didn’t do:

We didn’t buy the LED lights.

Where we are stuck:

Research fuse and 24V lights

Notes/Misc:

After discussion with Greg, we have decided to alter our plan slightly again.  Instead of hacking into the encrypted DX BUS, we have decided to basically disable an unused drive as a motor control and then enable that drive as light control.

Team Glen – Progress Report I for Prototype II: Smart Mailbox System]

Goals for the week:

Come up with a code to read the key on each RFID TAGs .

We spent some time testing the code for reading the RFID tags.  The goal here is that once we can read each key, we will save those keys.  The next step will be to implement a code that matches the already saved keys with the one from a totally different TAG.  If there is not a match, nothing will happen.  However, if a key correspond to one of the allowed keys, then an LED will be turn on/off. This LED will be later replaced by a stepper or servo motor.  The stepper or servo motor will be used to lock/unlock the mailbox door.

Meeting times/dates

We met as a group on Friday for 2 hours from 12.30 to 2.30.

Individual Hours:

Tetteh – spent 5 hours working on the code to read the keys stored on each TAG.

Dhreen – spent about an hour researching on how the RFID tags connect to the scanner antennas 

Glen – Working about 0.6 hours on RFID Code for our first program that will read our Tag ID’s.

What we did:

We do have a code for reading the keys, however this code is not returning the keys yet.

What we didn’t do:

Debugging the code.  After the code is done uploading onto the Arduino, the below error message is displayed:

avrdude: stk500_getsync(): not in sync: resp=0×30

Where we are stuck:

We are not stuck.

Notes/Misc:

The shipment for the RFID tags was not received until yesterday evening.  Which did not give us much time to debug the issue we are having.

S.R.P.R – Progress Report I for Prototype II: Dual Mode Table

Goals for the week:

  • Go to The Yard and see what we can find for our project
  • Meet with John on Wednesday and get help on how to use H-Bridge
  • Try to get all the equipment for Prototype II by this week.

Meeting times/dates

Saturday at 1 pm -2 pm

Wednesday at 10 am – 11:30am

Individual Hours:

Each member of the group are planning to spend a minimum of 3-4 hours.

What we did:

What we didn’t do:

We don’t have styrofoam cut out for the prototype II. But we have planned to work with Tom on this Saturday.

Where we are stuck:
