EVA

26 Mar

Updated the dates for building and testing circuit as I don't know how to properly add new ones without messing up the totals. The totals for both building and testing of the circuit have been updated according to the totals from the log. We are getting closer to being back on track but are still behind. Problems with getting the circuit working have added a lot of testing hours that have caused the budget to go quite a bit higher than originally planned along with starting over with the pump circuit. SPI is looking good while CPI is just shy of the lower limit.

Modified the dates for building and testing for the new pump circuit and totals were updated. The circuit is built but is not working correctly so more testing is required.
The original pump circuit will be put on PCB this coming week in case we can't get the new pump circuit working. We are behind and over budget but should hopefully be able to catch up a bit time-wise this week.
The temperature sensing circuit is built and just needs the code uploaded to the microcontroller board.

12 Mar

I wasn't sure how to add in existing tasks with the new date so the dates stayed the same but totals for " Test circuit", "Acquire parts", and "Parts" have been updated.
We continue to fall behind first due to the pump circuit not working the way it should and we are now going off our tech advisor's suggestion to try a new pump circuit. This will cause us to fall further behind. Parts have been and are still in the process of being purchased for the new circuit. What saving we had in parts before are now gone and are over budget due to delays.
We are hoping to finish getting the parts and get the new circuit together asap and hopefully get back on schedule.

We are still behind on some tasks due to a lack of knowledge.  The building of the circuit went smoothly and we were under budget there. We started to test the circuit earlier than planned but due to the circuit not working properly all the time we have already put in triple the hours than intended. We believe that part of the reason for the circuit not working properly is due to cheap parts IR sensor will not adjust like it is supposed to.

 Our EVA graph is almost identical to the last update. Not everything has been purchased yet but  even so, parts and tasks are under budget. We are a bit behind in a few tasks but not by much.  The next steps are to wait for parts to ship in and start building the circuit on the breadboard with what part we currently have. We need to ask our technical advisor for some help in the power source for our circuits.
