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.

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 an 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.

Cypress Robot Kit

Featured Project

Cypress is looking to develop a robotic kit with the purpose of interesting the maker community in the PSOC and its potential. We will be developing a shield that will attach to a PSoC board that will interface to our motors and sensors. To make the shield, we will design our own PCB that will mount on the PSoC directly. The end product will be a remote controlled rover-like robot (through bluetooth) with sensors to achieve line following and obstacle avoidance.

The modules that we will implement:

- Motor Control: H-bridge and PWM control

- Bluetooth Control: Serial communication with PSoC BLE Module, and phone application

- Line Following System: IR sensors

- Obstacle Avoidance System: Ultrasonic sensor

Cypress wishes to use as many off-the-shelf products as possible in order to achieve a “kit-able” design for hobbyists. Building the robot will be a plug-and-play experience so that users can focus on exploring the capabilities of the PSoC.

Our robot will offer three modes which can be toggled through the app: a line following mode, an obstacle-avoiding mode, and a manual-control mode. In the manual-control mode, one will be able to control the motors with the app. In autonomous modes, the robot will be controlled based off of the input from the sensors.
