Work - R&D electronics: 10.00 Time - Hours due June 30, 2016

Solving more difficult technical problems, troubleshooting, repairs that require some in-depth knowledge, but not in the context of a precise, pre-planned task.

Visit to Robco to debug XBee packet loss

April 21, 2016 2.50 Time - Hours Done by Tibi

Worked with Jim at the test bench. I looked into problems with the system, as it is manipulated by other users. Inventories wires that need to be more stable. Made list and will bring them from the SENSORICA lab the next day, and improve the wiring a bit. I also assisted Jim a bit with debugging the flow meter. We tested the entire sensor node to see if it works, if it got some water damage.

I am also logging 0.5h for analysis and knowledge building, sent an email to the project group to inform of potential problems if the R&D electronics and R&D mechanics and the business component aren't on the same page. I see potential costs generated from braking things. This was also about setting expectations for the first sensor node prototype, and lay out a vision for continuous improvements.

Task #411
Finished the displacement sensor, I put some rubber around the sensor to make it waterproof and I covered everything with a heat shrink tube. It's now ready to go.

Task #411 Worked with Tibi to finish routing the wiring from the harness to the PCB. This involved wiring the mapped connections, testing each sensor for correct connection and re-enforcing integrity of the connections.
Last sensors were added and tested.
Data collection was turned on to analyze signal quality and noise. Some problems were noticed with the thermocouples and the new soldering junctions. Some wiring shields were created to resolve the issoe.

Task #411
Fixed the node to the pump. This required some cutting and drilling metal for the support, screwing the node to a metal support and organizing the wires around it with Lai.

Task #411 Started connecting the RJ-45 harness to the node's PCB one sensor at a time.
This involved soldering the mapped wires from the female connectors to the pcb and the male pins to the RJ-45 box. Some debugging was required with the load washers and shaft temperature sensor.

Task 411

Mechanical attachment of the protoPCB board inside the not-a-box of Sensor node 1. Required some Dremel drilling and fixing of the board inside the casing.

Task 411

I worked today with Tibi on wiring.
We connected all the sensors with new cables and connected these cables in the connector box.
We cleaned the proto-PCB board of extra wires and prepared it to be connected to the connector box.

This task required mapping the wire connections, cutting wires and placing connectors on them, soldering wires, fixing connections with shrinking tube and glue gun, all that for all the sensors.

To Do:
We now need to test all sensors individually.
We created a paper map of wire connections. We'll put it in a digital form once the sensors are tested.
We need to mechanically fix the PCB in the case.

Documentation will be added here

Troubleshooted the fluid level sensor, which apparently has a problem. I had to remove it from the sensor node, to install it on a separate Arduino board, and to test it independently. In conclusion, it worked. The problem was somewhere else. We found that the power supply cable to the sensor node was chipped and at times we had a short. I fixed this cable. We didn't have time to do a final test of the sensor node, because we moved to work on the vibration sensor.
