Getting Parts for Your Project

Steps for obtaining parts

As soon as you know which parts you'll need for your design, it's a good idea to start acquiring them. There are several methods that varying widely in cost and waiting time. The primary methods are listed below, most desirable first.

Note: Each group has a budget of around $40 for parts and resources that may be charged to the ECE 445 course account. If small parts are needed, it is strongly encouraged that you just buy it yourself. Since there is no required textbook for the course, we figure the small monetary payout is more than offset by the savings in time and hassle for your group. Also, if you intend to keep your project when you're finished, we ask that you purchase the parts yourself.

Checkout Hardware from ECE 445

The Srivastava Senior Design Lab has a wide variety of hardware available for use in projects, including microcontrollers, DSP boards, LINX RF transmitters and receivers, GPS units, webcams and more. These things can all be checked out from you TA for use on your project. Please note that parts that you checkout from the lab must be returned by the end of the semester or your student account will be charged.

Please see the working inventory of all components available for checkout in the lab. This inventory is as inclusive as possible but there may be additional items around the lab - feel free to look around but items must be checked out through a TA.

Electronic Services Shop

The Electronic Services Shop in 1041 ECEB has many parts and components that are freely available to senior design students. You will find many of the passive components you are likely to need. You can check the Electronic Services Shop catalog for a list of parts available in the Electronic Services Shop. Note that there will be some items available that are not in the catalog, so you might want to check with the Electronic Services Shop staff if you do not see something you need on this list.

The Electronic Services Shop also has larger components, such as transformers or large batteries. You will need an instructor to check these out for you. All major parts provided by the service shop must be returned at the end of the semester.

MY.ECE

Parts may be special ordered from a number of companies available through your my.ece web page parts order form. This option requires TA approval before the order is processed. Once you've placed the order, email your TA to let them know there is an order waiting for their approval so that your order can be processed as quickly as possible. Otherwise, the order may be delayed! Since many part orders are usually placed with common vendors like Digi-key, these orders may be grouped into bulk orders placed on Wednesday and Friday.

Parts ordered through this method will be delivered to the ECE Supply Center.

ECE Supply Center

An alternative option is to have the parts ordered from the ECE Supply Center (located in 1031 ECEB). For this option, you will need to fill out the ECE Supply Center Ordering Form and have your TA sign it. Alternatively, you can charge the parts to your student ID if you need to pay for them yourself.

Free Samples from Companies

It should be mentioned that companies many times are willing to provide small quantities of their products to students engaged in design projects. You might consider approaching the manufacturer directly, particularly regarding their newer products which they are interested in promoting. Don't count on success with this, but it has often been very useful.

Personal Purchases

It is always possible and encouraged to purchase your own parts from a local store (Radio Shack, Best Buy, etc.) or order them from online vendors. Subject to prior approval from your TA, reimbursements can be made. The Department will need the original copy of your itemized store receipt or invoice in order to make the refund. Purchases made without prior approval will not be refunded, in any case.

The Business Office (last resort)

If all of these methods fail, your order will need to go through the ECE Business Office with the help of your TA.

Wireless IntraNetwork

Featured Project

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
