Design Challenges• Developing LED sensing mechanism
• Experimented with various sensing techniques
• Developing a custom microSD card driver to handle individual data packets and I/O in blocks to the microSD card• Incorrect traces on PCB found after lot of
debugging
• Creating a reliable and safe high-voltage (110VAC) control solution
Individual ContributionsVineeth Harikumar
• Overall software design for all the drivers
• PCB design and debugging
• Prototyping the different components
• Hardware + Software interaction
Individual ContributionsSiddharth Bhosale
• Schematic and PCB design
• Hardware prototyping and PCB population
• LCD menu and RPG integration
• System Integration and Packaging
Individual ContributionsSriram Rangaramanujan
• Schematic Development
• PCB design and component population
• LED Sensing
• Overall hardware development
Individual ContributionsFabian Widyadri
• QA on the PCB and schematic design
• Developed LCD driver
• Developed microSD driver
• Hardware and software interaction
Project-Specific Success Criteria
• An ability to detect change in light in a room with an LED
• An ability to control the printer’s power state and display it via an LCD on the detection of change in light
• An ability to accept incoming print jobs and queue the jobs up using local memory while printer is in sleep mode
• An ability to wake up printer and forward the queued up print jobs using standard protocol
• An ability to control and set the various timeout options for the printer’s sleep and hibernate states based on user input
