Enes Palaz Status Update

• What did you personally accomplish this week on the project?

I worked on debugging the connection of our own board to galvanometers and the laser. Jake is working on further fixes of the problems diagnosed. Also, this week, I and Eliana identified potential methods of interpolation to reduce the number of points in contours.

•  Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?

Everything is on schedule.

• What deliverables do you hope to complete in the next week?

Integration of our own board to Pi and galvanometers. And integration of the laser setup to our board and calibration of color values for those lasers in DAC code.

Jake Zimmer Status Update

• What did you personally accomplish this week on the project?
  • I tested the safety sub-board this week and found an issue the safety microcontroller corrupting the output from the dac. I have determined what the issue most likely is and will fix it tomorrow. Upon fixing it, I will update this document.

 

•  Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
  • On track.

• What deliverables do you hope to complete in the next week?
  • Fix the board
  • Design and build the mounting and enclosure for everything

Eliana Cohen Status Update

• What did you personally accomplish this week on the project?
  • Assisted with integration/testing of new board in current setup
  • Confirmed interpolation point method resulted in 10fps goal on hardware
  • Started planning 3D CAD design, the laser-cutting will occur over break

 

•  Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
  • On Track

• What deliverables do you hope to complete in the next week?
  • Laser cut and assemble the housing for the system
  • Work out any other additional integration bugs
  • Test new lasers with system and debug any additional tracing clarity issues

Team Status Update

 

• What are the most significant risks that could jeopardize the success of the project? How are these risks being managed? What contingency plans are ready? 

 

Due to the current laser diodes we’re using, we have traces (caused by delay in turning off laser diodes) that interfere with the visibility of the rendered frames. We will test with more expensive lasers that should have less of a delta turn-off time, which should result in a more clear image. 

Also there’s a risk that the safety subsystem might need more intensive redesigns, but we have the skill to add botch-wiring and other repairs even if our initial board design isn’t perfect.

 

• Were any changes made to the existing design of the system (requirements, block diagram, system spec, etc)? Why was this change necessary, what costs does the change incur, and how will these costs be mitigated going forward? 

 

Ordered newer lasers that contained R, G, and B lasers, but no additional changes.

 

• Provide an updated schedule if changes have occurred.
