Getting Parts for Your Project :: ECE 445 - Senior Design Laboratory

Getting Parts for Your Project

Student groups have a budget of $50 per student as of fall 2023. This money can be accessed through your TAs CFOP number. The ways parts can be sources are listed below in order of desirability.

1. Lab Kit

Each group is issued a locker and lab kit. A lab kit should include banana plugs and a breadboard.

2. ECEB 2070 Lab

There are many parts available for free in the ECEB 2070 lab such as THT passive components, MOSFETs, and line operated DC power supplies.

3. ECE 445 Inventory

Your TA can check out parts ECE 445 stores in white cabinets at the back of the lab: link. This inventory spreadsheet has not been updated in some time. There are items on this list that may not be in the cabinets and there are items in the cabinets that may not be on this list. Use this form for checkout: link

4. Electronics Services Shop (A.K.A. ECE Services Shop)

The Electronics Services Shop is located on the first floor of ECEB near the cargo elevator in ECEB 1041. They have a large stock of THT ICs (such as op-amps), potentiometers, motors, resistors, connectors, etc. Visit them when they are open to pick up parts.

Self-Service Inventory

Recently, they have started stocking 0805 surface mount passive components, crystal oscillators, microcontrollers, and linear regulators. The microcontroller portion of your board can probably be built entirely with parts from the Electronics Services Shop.  You do not need to pay for parts you obtain from the Electronics Services Shop.

E-shop website

To obtain SMD parts from the E-Shop, please use the Excel form sent out by your TA. Fill out the form and email it to your TA, who will place the order with the E-Shop and pickup it up. Your TA will receive an email when the parts are ready and will bring them to your group in the lab. Your TA must pickup the parts from the E-Shop; the E-Shop will not release parts to you directly.

5. ECE Supply Center (A.K.A. ECE Store)

The ECE Supply Center is located on the first floor of ECEB in room 1031 near the loading dock. You must pay for parts out of pocket or with your TA's CFOP number. They stock breadboards, project boxes, jumper wires, THT LSI logic ICs, THT analog ICs, and more. This is a fantastic resource for building prototypes. You can search their catalog here: https://my.ece.illinois.edu/storeroom/catalog.asp.

6. 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.

7. MY.ECE Ordering (last resort)

You can order parts from amazon, digikey, mouser, etc. using the money provided to you by the course with your TA's CFOP number. Orders placed through this avenue must be approved by your TA through myECE. If you order multiple parts through digikey or mouser, please provide a shopping cart link. This method of ordering is best for parts that cannot be found in any of the sources listed above. This includes SMD MOSFETs, high performance ADCs/DACs, power converter ICs, SMD op amps, modem ICs, etc. Please refer to this tutorial for more instructions: http://courses.engr.illinois.edu/ece445/lab/resources/ece_purchasing_app_tutorial.pdf

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. Personal purchases will not be reimbursed by the department.

Problem:

The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

http://buildingcampaign.ece.illinois.edu/files/2014/10/touched-up-Donor-wall-by-kurt-bielema.jpg

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
