Lab Equipment

The Srivastava Senior Design Lab has a wide selection of equipment that provides nearly all of the capabilities of the other ECE teaching labs in one place. Although the equipment may not be identical to that found in these other teaching labs, similar functionality is offered. Use the experience of learning new equipment as a way to expand your horizons. If you are using a piece of equipment for the first time, ask a TA for assistance, to make sure you understand how to safely use it. If the available equipment does not meet the needs of your project, talk to the course staff, and we will help you find what you need elsewhere on campus, consider purchasing it for the senior design lab (if it would be used by many groups), or brainstorm alternate ways to solve your problem.

Lab Kits

Each team is provided with at least one lockable storage drawer in the lab as well as a portable lab kit. An additional drawer and/or kit may be issued as need arises and facilities allow.

The lab kit includes a box with carrying handle and contains a wiring board for prototyping circuit projects, a multiple-output power supply, a digital multimeter, and a set of 8 cables (2 bnc/bnc, 2bnc/pin, 2 banana/banana, and 2 banana/pin). This is checked out to you by your TA at the beginning of the semester and must be returned undamaged at the end of the semester. Missing lab kits will result in an encumbrance or withheld diploma and a charge of $500.00, so always be sure to lock your lockers! Also, do not store any cables from the lab in your kit. Doing so will result in a loss of points.

Test Equipment

Most equipment is connected to the PCs via HPIB cables. Below is a sampling of the test equipment available:

Specific setups at the various lab benches can be in the listing at the bottom of this page.

Computers

The lab has PCs with enough processing power for the needs of nearly any senior design project. These machines are networked to a high-capacity laser printer (printing will count against your standard print quota). Each has an Ethernet connection to the campus network, an HPIB interface card connecting it to all of the standard instruments on its bench, and a sound card. The computers are maintained by Engineering IT, located in 3080 ECE Building.

The PCs are presently configured with the software shown here. Their primary uses include:

Fountain show

Featured Project

## Team

- Dingyi Feng(dingyif2)

- Tianli Ling(tling3)

- Zhelun Lu(zhelunl2)

- Shibo Zhang(shiboz2)

## Problem:

A fountain show on campus can make students feel more relaxed after class. However, some fountain shows only have monotonous, stiff, and single actions. Besides, they cannot automatically generate action and light effects. Compared with large fountain shows, small and medium-sized fountain shows have the advantage of time and space. In most cases, a large fountain show only has preloaded music which cannot be decided by audiences. Large fountain shows also require people to design the action and light effects for each music, which takes lots of time and effort. Compared with the large fountain show, our small fountain show will be more energy-efficient and environmentally friendly. During the COVID-19 pandemic, large fountain shows might result in large crowds gathering, but a small fountain show can reduce the risk of infection.

## Solution Overview:

Our fountain show would be built at a pool on the sourthwest of the main lake on campus. By manually programing, the fountain show could realize changing lighting effects and movements. Besides, our fountain show could also identify the music which was imported into our system, and automatically generate the lighting effects and movements with the music. If time permits, we will strengthen the human-computer interaction of our product. To be specific, people could scan the QR code or use our online system to choose the music they want, so that they can enjoy the fountain show at any time.

## Solution Components:

### Control Subsystem:

- Music colleccting and analyzing subsystem: Computer that can import music signals and analyze them.

- Converting subsystem: After music signal is analyzed, we need computer to convert useful signals into digital signals. Digital signals will be used to control LEDs and other mechanical subsystems.

### Mechanical Subsystem:

- Pump Subsystem: Water pump that can pump water from the lake. Valves will be used to control water’s flow rate of each nozzle.

- Lighting Subsystem: LEDs are needed to light our fountains. They are controlled by microprocessor on PCB. Their brightness and color can be changed with music.

- Motor Subsystem: Two motors are needed for each fountain nozzle to control the movements. The motors are controlled by microprocessor on PCB.

### Power subsystem:

- The pump is drived by DC power (12V 20~30A). PCB and computer will be drived by USB (5V 1A). Full module power supply with 12V and 5V output is needed.

## Criterion for Success:

- If it can successfully identify a piece of music and convert it to electrical signals that we need in controlling LED’s lighting and nozzle’s moving.

- If the whole system can work stably for a long time and whether it is safe to use without electric leakage or other problems.

- If music playing, fountain movements and LED lights are synchronized.

- If the fountain system is neat and whether the fountain performance is ornamental enough.
