Project Preference
We were not given a choice for this project.

Problem Statement
Our project was to create a closed circuit that included a light switch (LED), rotary type potentiometer, resistor, and a power source.

Project Plan
This project was fairly simple and did not need a 4 week plan. We did encounter a problem with bridging the light source to the rest of the materials. Our solution involved using jumper cables and the use of a soldering iron to allow for a conductivity between the materials. Also, the project is already finished.

Introduction
Rectenna utilizes microwaves and converts it to A/C electricity. That energy will be sent from a router and transmitted through a whip antenna to another receiving whip antenna that converts it into energy a phone could use.

Rectennas generally include an antenna, rectifier, and voltage multiplier.

Goal
Create a rectifier/regulator (R/R) to convert A/C into usable D/C that charges a phone wirelessly.

Week1 Narrative
We delegated tasks amongst ourselves and there are many parts we need:

$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

$Magnet Wire 28 Gauge AWG Enameled Copper 1000 Feet Coil Winding 155C Red

Week2 Narrative
We finished the proposal and presented to the class. Jey wanted the group to edit the block diagram to show that the transmitter and the whip antenna has the antenna symbol. He also wanted the group to make an excel file to show each members’ roles. They had to be detailed in a way that every member had their job.

Meanwhile, we continued to search for parts. I continued my research on rectenna technology, wave propagation, etc.

Week3 Narrative


We edited the block diagram that Jey told us to change. Also, we updated the excel file, showing our members' tasks and roles. During class, Jey gave us a great website called Rogers Cooperation. This company gives out free electric circuit board samples.

Meanwhile, the technician did not answer his work phone or answer reply to our email. We are still working on contacting them to see if the x acto knife works. I have been bouncing from a few people who tell me they cannot answer my inquiry because there is someone else who handles such questions.

Week4 Narrative
I sent an email to Foerster about the SMA jacks for the base mounts from minicircuit.com. We need one SMA- FEM to SMA-FEM adapter as well as two SMA-M to BNC-F adapters. Awaiting Foerster's answer.

We are still working on contacting the Rogers Corp for some electric circuits.

Here is the transmitter Bob is working on the right. He is working on being able to send pings and hopefully recieve them as well.
