BA(Hons) Visual Communications/Graphic Design: Level 4 DL835 BSc (Hons) Creative Media Technologies CA2 CMT2 Electronics PCB Design Paul Comiskey paul.comiskey @iadt.ie Date: 18/01/21 Text Course notes on Blackboard CA Overview You are required to create a Schematic Diagram, design a PCB, get it manufactured and produce a costed Bill of Materials for the provided design. You will report results as detailed in the CA below. You will then write and submit a report. Description of Concept Printed Circuit Board (PCB) design is an important aspect of both analogue and digital circuit design and is an essential skill in Electronics. The computer-aided design (CAD) tool Eagle PCB Design will be used to complete the CA. Fabrication will be by submission to Seeed Studio. Rationale This CA is designed to acquaint you with the application of PCB design to electronics design and to familiarise you with concepts such as schematic entry, electrical and design rule checking, component libraries, board fabrication and creation and costing of a bill of materials. Aims and Objectives This project requires you to complete the schematic, PCB design and costing for an LED Flashing Circuit. You will submit the design to be fabricated and write a report to be submitted via Blackboard. Specifically: • Complete and test the schematic diagram using the information provided in the CA2 folder on Blackboard. • Complete and test a PCB design for the circuit. • Create manufacturing (Gerber) files and submit the design to Seeed Studio for manufacturing. • Write a report (approx. 10 pages), to include Title page, Table of Contents and Sections on: Schematic design PCB design Bill of materials (BOM), to be in Excel format with suitable ordering and costing information provided via Radionics. (See example provided in class and in CA2 folder for best practice.) Description of the manufactured PCB References Include sufficient circuit diagrams, PCB layouts, etc. in your report to show every stage of progress. mailto:

[email protected] Assessment This CA is worth 35% of the total CA marks for the year. The CA will be assessed via your report and submitted design files as follows (/100). The finished PCB will be visually inspected in class. 1. Schematic Design 30% To include a description of each stage of the process. Include an A4 frame, correctly labelled components and Title Block. 2. PCB Design 30% To include a PCB with rounded edges, four 3mm mounting holes, ground plane and well- prepared, uniform silk screen. See class demos for examples of best practice. 3. Finished Board 10% 4. Report 30% Important considerations in your report: Quality of writing Adherence to report structure Presentation and explanation of results Referencing Your report and your zipped, correctly named project folder containing all design files, will be submitted to Blackboard via TurnItIn which will check and report back any plagiarism such as copying of text and results within the class. Please be aware that plagiarism is taken seriously by IADT. Use the following name format: CA2_John_Smith_studentNumber.zip The CA report and zip file are due on Sunday, March 7th before 11:59pm, via Blackboard. The PCB will be inspected when it arrives, which may be after the report submission date without penalty. The circuit diagram, plus tutorial and all materials and information required to complete the CA are included in the CA2 folder on Blackboard. BA(Hons) Visual Communications/Graphic Design: Level 4 DL835 BSc (Hons) Creative Media Technologies CA1 CMT2 Electronics Analogue Circuits Simulation and Analysis Paul Comiskey paul.comiskey @iadt.ie Date: 12/10/20 Text Course notes on Blackboard CA Overview You are required to analyse and create a simulation for each of the circuits described below. You will report measurements and results as detailed in the CA. You will then write and submit a report. Description of Concept Computer simulation is an important first step in visualising and predicting the behaviour of a wide range of analogue and digital circuits and is an essential skill in Electronics design. The simulator LTSpice will be used to determine currents and voltages in circuits. Calculations of essential quantities such as power consumption are also important and are used to complete the design cycle for an electronic circuit. Rationale This CA is designed to acquaint you with the application of Circuit Simulation to electronics design and to familiarise you with basic calculations such as current, voltage and power consumption. Aims and Objectives This project requires you to complete an LTSpice model for each of the circuits in Figures 1-3. You will also complete a simulated breadboard layout of each circuit using the software Fritzing (Fritzing.org) and write a report to be submitted via Blackboard. Specifically: • Complete the calculations specified in the table accompanying each circuit. Use an equation editor in Word, or similar, to include the calculations in your report. • Complete an operating point (.dc) simulation of each circuit using LTSpice and record, in a table, the dc voltages and currents measured in the circuit. • Build a simulated breadboard layout for each circuit using the circuit layout application Fritzing. • Write a report (approx. 10-15 pages), to include Title page, Table of Contents and Sections on: Calculations Simulations Fritzing breadboard circuit construction References Include sufficient circuit diagrams, breadboard layouts, etc. in your report to show every stage of progress. mailto:

Calculations 25% To include all calculations documented using an equation editor 2. LTSpice Simulations 25% 3. Fritzing Models 20% 4. Report Writing and Quality 30% Important considerations in your report: Quality of writing Adherence to report structure Presentation and explanation of results Referencing Your report will be submitted to Blackboard via TurnItIn which will check and report back any plagiarism such as copying online designs, or copying of code, text and results within the class. Please be aware that plagiarism is taken seriously by IADT. Your three LTSpice files and the three Fritzing files will be uploaded to Blackboard as a single zipped file with the following name format: CA1_Joe_Bloggs_studentNumber.zip The CA report and zip file are due on Sunday, Nov. 29th before 11:59pm, via Blackboard. For your report submit a pdf only, in the following format:
