Status update
Status Update

  • Building an electronic party game played on a mat

  • Finishing construction

  • Implemented and tested basic i/o functionality

  • Music sampling/pwm

  • Built so far:

    • 1 Epic circuit

    • 16 Silicone pads w/embedded LEDs (4)

    • 16 Plastic rims

    • 1 Hardboard mat comprised of 4 hinged panels and 16 total contact points for the pads


Experimentation plan
Experimentation Plan

  • Latency

    • Pad color update time

    • Full game cycle time (input, compute, update)

  • Throughput

    • Pad reads/sec

    • Full game cycles/sec

  • Experiment to find latency and throughput

  • Test: read pad inputs, compute new pad colors, write out new pad colors

  • Tektronix TDS 3064B (in Robotics Club)

  • Synthetic workload but is representative of typical system tasks

Looking forward
Looking Forward

  • Lessons Learned:

    • Construction can get very involved

    • Debugging difficulty does not vary linearly with circuit size

    • Use wall power to avoid fanout issues and low resistor values to maximize LED brightness

  • What’s next:

    • Mount plastic rims to mat

    • Connect all hardware to the epic circuit at once to test system as a whole

    • Finalize game code

    • User testing
