Project 2 "Requirements"
Project 2 should be a "step up" from the first project. The goals are to have the system be more digital and to use more modern techniques overall. The "requirements" below are all negotiable, but any successful project should include most of the features listed.
- The system should be based around a microcontroller. The microcontroller — and all supporting circuitry — must be incorporated into the PCB. A recommended microcontroller is the Atmega328 from Atmel / Microchip. This is the controller used in the popular Arduino Uno, and you have a couple of "bare" chips in your 333 lab kit. However, depending the computational horsepower needed for the project, you can choose a different controller, either smaller or bigger. Note: You cannot use an Arduino in your final project! You can use an Arduino for prototyping, but the final product must have the microcontroller included.
- Voltage regulation should be done using switched-mode regulators. You can use standard controller chips from the usual suppliers, or you can build your own, if you'd like.
- The PCB should be made predominately with surface-mount parts. Standard exceptions are allowed for the microcontroller and the SMPS controller — you can use through-hole parts for these if you want, although you can certainly use surface-mount versions for these as well. During proto-typing, you will probably want to use through-hole parts, but the final project should use mostly surface mount.
- Power input will be provided by a 12-VRMS wall-plug transformer. (Purchased from AllElectronics). You will also have available 2.1-mm barrel plugs and diode bridges: through-hole and surface-mount. What you do beyond that is up to you. If you want to use battery power, it must be done in conjunction the AC input, i.e. your system should run off of either AC or battery power. In fact, this may be an excellent opportunity to use re-chargeable batteries with the charger built into your system.
- You are expected to write your own software to run the microcontroller. Copying some janky code off the internet is not acceptable.
Project proposals and reports
Both projects have the same proposal and reporting requirements. There are 4 requirements for each project — three in-class presentation and a written report: 1. Project Definition presentation, 2. Design Review presentation, 3. Project Completion presentation, and 4. written Final Report.
The Project Definition presentation serves as the kick-off to the project. In the definition presentation, the team will describe the project goals in general terms, enumerate specific system requirements, lay out a test plan, and provide any preliminary circuits or design details. The presentation should also include a project abstract, which will be used in the final written report.
Here is an example of a project definition presentation. Here are templates ( powerpoint and keynote ) that can be downloaded and used when preparing your definition presentation. This presentation should be brief — less than 5 minutes.
The Design Review presentation is given after all of the design and prototyping work is completed, but before the PCBs are sent out for fabrication. The design review presentation should include:
- A complete schematic of the final circuit — you might be able to use the schematic generated during the KiCad layout. (The schematic can be broken into functional pieces and presented on separate slides, if that improves clarity. )
- Design calculations and simulations.
- Results from testing the prototype circuit and comparison with design expectations. (Preface the test results with the test plan given in the first presentation.)
- Discussion of implementation difficulties, existing problems, trade-offs, or modifications from original design.
- A complete Bill of Materials (BOM). The BOM should include costs of the various parts and estimated cost of the PCB.
- Overview of the proposed PCB design. (May need to be presented in "snap shots" that are spread over several slides for better clarity.)
- Photos of prototype circuits. Optional: You can also bring the prototype circuit to "show and tell".
When submitting the DR presentation, the group should also submit their KiCad file with the PCB layout. This presentation will certainly be longer and more detailed that the first presentation. However, the presentation time will be limited to 10 minutes, so the project team will probably need to choose which slides to highlight during the presentation. (All of the information about the project should be present in the powerpoint file, but the discussion of some details might be curtailed slightly in the interest of time.)
- The Project Completion presentation will be given after system has been built and tested on the PCB. This presentation will be similar to the Design Review, but probably more succinct since the results should be similar to what was previously reported in the DR. The presentation time will be limited to 5 minutes.
- After all project work has been completed, the project team will write up and submit a Final Report, comprising the information contained in the three presentations.
Here a list of project ideas. You can pick from the list for either of your projects. You can branch off from one of these to make a somewhat different that interests you. You can use your own unique idea, but check with GT first before starting on it.
