Plans for MSD II

Over the break the EE's Are planning on continuing to troubleshoot their systems and try to get ahead of the MSD II curve. Upon returning from break, we will immediately be obtaining the materials we need and begin building the grinder since it is the most complex subsystem that we will need to get working. After this we will move onto the holding tank and reactor since they need to mate up fairly accurately. We are anticipating this to take the majority of our time throughout the first month back. After, all of these components are built we will finish the drawer assembly and finalize the auxiliary systems. After this is complete it will be up to the EE's to apply their control of the entire systems and Up to the ME's to troubleshoot mechanical issues that arise.

Gate review results for MSD II

Notes from Meeting:

1. Sensors- We have data receiving capabilities; no display on website; chamber levels good; gas and moisture are not calibrated or don’t know if data received is correct; waited until last minute and unsure of accuracy. How to fix- programming experience, feedback and automatic response.

2. Grinder- Rework blades; fix packing issues; gears should be enclosed

3. More time building and feasibility less time with structured design process

4. Trying to make compost was a waste of effort. Should have used a bin already going

5. Is this a useful task? (discussions about stepping back and evaluating the productivity of current work)

Lessons Learned: have more accountability, first group for the ees, mes beaten down by the end, prps are horrible, give us legitimate numbers, budget met, double check the measurements, have the manager set and maintain a hard schedule.

Recommendations for the next group: New motor for grinder focus on back end of the website and interaction for the user. Ventilation will be a forseeable issue. Data accuracy is weak.
