Week4 Narrative
''ENES 100 – 503

Group 2

Honeybadgers Engineering Proposal Rectenna Group The project we chose for our group was the rectenna. We will be creating a regulator/rectifier for the purposes of converting the A/C voltage into useable D/C current to charge a phone from an antenna using a change pump. This will all occur wirelessly; without the use of wires and cables. Not only does this project interest us as a group, but it seems difficult and should keep our interest. We will utilize wikiversity and our own notebooks to record and describe our processes throughout this project. Daily and weekly reports will be made and achievements and failures will both be equally highlighted.

Develop a block diagram for rectenna system and determine the scope of the project

1.	Develop a list of tasks/Assign tasks among team members of project

1.	Keeping up to date with the group wiki page (To include a daily update of what we accomplish in each of those days) (Chan) 2.	Electrical circuits understanding (Sam) 3.	Finding accurate pictures to associate with our project (All) 4.	Research and development (Wiki page links, youtube links, etc) (All) 5.	Writing the papers and associated documents (Bob, Jen) 6.	We need a 915 MHz router (Chan) 7.	Tools (Bob) 8.	Electrical supplies (Bob) 9.	 Write the proposal (Bob, Jen) 10.	Get a whip antenna (Bob) 11.	DIY PCB Double-sided Prototyping Board (5x7cm, Pack of 10) Amazon

2.	Parts list, Equipment list and Budget 915MHz router Phone Copper wires Tools: Screwdrivers Blade (for splicing wires) Wire strippers Soldering iron Multimeter Heat gun Electrical parts: $Copper foil $PSU $Resistors $Transistors $Diode $LEDs $Capacitors $Prototype board 5x7cm pack of 10 (Amazon.com) $Soft Copper Tubing 1/4-Inch OD x 10-Foot Coil with Caps On Both Ends (Ebay) $Magnet Wire 28 Gauge AWG Enameled Copper 1000 Feet Coil Winding 155C Red

3.	Prepare a schedule for hardware and software development and testing Week 1: We will fill out the proposal. Write in our notebooks. Project 4. Look online to find compatible parts. Week 2: More information, getting parts like the base, whip antenna, circuit board, and R/R Week 3: Begin putting together the whip antenna with the base/Setup the RR/Setup Jay’s diode and AC to DC converter. Week 4: Have the router power being generated Week 6: Be able to receive the energy from the transmitter Week 7: Be able to convert the received energy and convert to DC Week 10: Finished project/Presentation

4.	Milestones and Deliverables

Basestation and whip antenna setup Diode and converter hooked up to RR Showing power converting Showing that the phone is charging Finished Product

Items we need from Amazon: 1.	Transmitter/receiver (We already have the Arduino UNO board) (NEED 2 OF THESE PLEASE) http://www.amazon.com/SMAKN-NRF905-PTR8000-wireless-transmission/dp/B00EJ9HN62/ref=sr_1_2?ie=UTF8&qid=1411481349&sr=8-2&keywords=NRF905+%28PTR8000%2B%29 (Below is a diagram showing the Arduino hooked up. We will be using a whip antenna and our dongles instead of the second Arduino shown. http://taillieu.info/index.php/hardware/110-nrf905-wireless-module-ptr8000-wireless-transmission-module-nf905se-band-antenna-c3b5
