2018-2019 ICS3U Engineering Tasks

 

Legacy PCB. TBA.


Project 5. Design Sessions. Your final ER prior to Christmas is to include a comprehesive review of your introductions to EAGLE and ViaCAD. Under Heading 2 styles (either EAGLE of ViaCAD) in the order you explored each application, document your three design classes within the section subheadings: Purpose, Procedure, Media and Reflection. You are NOT required to make a video for this Report, but the text and graphic support will be, as I mentioned, comprehensive. Here are the design projects each group was asked to develop,

Session 1

7-Segment Tester HC-SR04 Mounting Bracket
Session 2

Project 4. MatrixMadeEZ. For his PCB project in Grade 11, Hugo R. (ACES '19) imagined, designed, and developed a handy PCB that future Grade 11s could exploit to hone their LED matrix software animation skills. We're going to incorporate Hugo's terrific little device into an ambitious standalone project. To assist with your time-management pursuits, I'm strongly suggesting you discipline yourself to stick to the timeline below to enable a successful conclusion two weeks from now, on Saturday November 17.

Task

  1. By Tuesday November 6. Before you head home on Tuesday, you've demonstrated that you've worked through the concepts introduced last class (Friday November 2) to the point that the standalone breadboard version of the ATmega328p I gave you can be flashed with the Blink sketch. This is accomplished with the help of your Sparkfun Pocket Programmer and the ACES ISP Breakout Board and cable I distributed. Bring your working system to my desk and I'll give you a PCB and 6-pin right angle header. The other parts can be found in your kits. Note: Be sure to orient your Matrix the correct way as it is virtually impossible to repair if it isn't.
  2. By Thursday November 8. You ARRIVE to our Period 3 class with your MatrixMadeEZ board soldered up and wired either to your Arduino or your standalone. Silk screenong on Hugo's board tell you how to solder it. I'll have mine ready to go and the lesson will introduce you to simple matrix PoV/animation techniques.
  3. The project requires that you develop some form of creative PoV animation involving more parts (sensors, ICs, etc) from your kit, functioning on your standalone Arduino and reflashable on the fly as evidenced in your video. The more unique it is, the better your mark.
  4. You'll appreciate the luxury of a four-day weekend to experiment if you maneuver yourself into that position by the time we break Thursday afternoon. Wise 11s are in the DES after school Tuesday and Thursday keeping up with their peers.
  5. By Wednesday November 14. As has seemingly become the norm, we only meet ONCE in the second week of this projects duration, on the Wednesday. Note: Parent-Teacher interviews are scheduled for Thursday the 15th and Friday the 16th so the DES is not available.
  6. Ambitious and organized ACES will consider pushing their creativity into possible areas such as 3D printing, soldering their standalone Arduino onto a (stackable?) PermaProto board(s), a deluxe ACES Knight Light using an LDR to control the MatrixMadeEZ's dimming feature (DM Pin) or digging deeper into the incredible ICs their kits or in the tipout bins at the back of the DES.

Parts List for Hugo R.'s MatrixMadeEZ PCB,

The 6-pin right-angle male header will allow your device to be mounted vertically in your breadboard, driven by your standalone Arduino. Make Hugo proud.


Project 3. Shift Register - Bargraph. When Tim Morland (ACES '18, Queen's Eng '22) was in Grade 11, he designed the adjacent output PCB based on the 595 Shift Register and a bargraph. Your toolkit contains the SN74HC595 IC, a 16-pin IC Socket, and a 10-LED red bargraph. The remaining parts, a 5-pin right angle male header, 330Ω 8-pin bussed resistor network, and Tim's PCB, will be provided to you.

You are asked to create a unique and interesting prototype that employs Tim's Shift Register-Bargraph output device.

In addition, just as James Lank dipped into his toolbox and incorporated the LCD screen into his previous ASCII & Buttons project because he was intrigued to discover its potential, each of you is required to do the same. Identify a part you have never previously used and combine it with this Shift Register-Bargraph output device in a meaningful way.

Finally, one shortcoming of this device is that there are 10 LEDs in the bargraph but only 8 outputs provided by the onboard '595 shift register. It's kind of like a packs of hot dogs are sold in dozens but the buns, in packs of eight. This is not good but it clearly presents an opportunity for the creative amongst you.

Your mark will be based largely on how creative and how DIFFERENT yours is from everyone else's and how potentially USEFUL your application could be. Give it some deep thought and push yourself hard your efforts could possibly form the basis for a future ISP. I'm looking for trailblazers this weekend, not followers.

Again, for the engineering and for the unique design and creativity.


Project 2. ASCII & Buttons. Time to let the horses run. We've reviewed the Arduino's recognition of the ASCII characters and it's ability to read (properly conditioned) button input. For your second project I want your imagination to take center stage in the pursuit of a creative application involving button presses, ASCII characters, some form of manipulation/processing of the two, and its display.

The -rating of this project is based on for the engineering and for the unique creativity your project will project (how's that for phrasing!). Standard ER sections apply with heightenend awareness of the video constraints now in effect (no music, stable camera and components, no spelling errors in the video titling, and not too many Persian carpet backgrounds)


Project 1. Traffic Light Assembly and Testing. Make the following updates to your ER,

  1. Add ICS3U to your title page after TEL3M
  2. Insert a Next Page Section Break at the end of your Grade 10 reports
  3. Insert a full divider page with ICS3U, in large font, centered on the page. Add another blank page, following.
  4. Adjust the new header to reflect the new ICS3U course code, but continue the page numbering in the footer.
  5. Begin this year's submissions with a report entitled, Project n. Traffic Light Assembly and Testing. For n you may continue the project numbering from last year or start again, your call.
  6. Be sure to update your ToC prior to submission.

Since many of you will be pursuing your driver's license in the near future, the focus of this first summary is the design, careful soldering, programming and thorough testing of a Traffic Light. For the assembly aspect of this project you will solder one each of a green, yellow, and red LEDs onto the section of stripboard you have been provided with. NOTE: The stripboard only has three strips. The placement and orientation of the LEDS is tricky and you must give it some DEEP THOUGHT if you're going to be able to program it so it operates correctly. Take care as there are NO replacement parts. A three-pin right-angle header, soldered at one end, will enable your device to be inserted directly into your Arduino's female port pins (see photo) Be sure to document your soldering of the device through media acquisition that you can include in your report. For the testing aspect, you will include media as well as a simple sketch based on our discussions in class. The fully documented sketch should cycle through the LEDs continuously with the green and red remaining on for 3 s and the yellow, 1 s.

In your report, include the sections Purpose, Reference, Procedure, Code, Media, and Reflection Heading 2 (or 3) style. A full Parts Table should appear right-aligned within the Procedure section.
