8/4
I started green training at the machine shop today. I will be building the Lucy air engine. I started cutting the parts for the assembly.
8/1
Same issues.
| Hypothesis: | Test: | Outcome: |
|---|---|---|
Bad connections | Measure the voltage across the pins themselves with a voltmeter. | The voltages from the "OUT" pins are ~11.25V, while the voltages from the "+9-12V" pin are ~3-4V. |
The "OUT" and "+9-12V" pins are mixed up | Swap those pins | Both the voltages are in the correct range, but it doesn't seem to respond to the wind. |
| The rainbow coded cables that live in the tube and the rainbow coded cables that live in the box don't follow the same color coding.test each of the pins with the voltmeter while testing how th | Take apart a spare and check | They are the same |
Issues 7/15
- Tested out the new power supply. It was able to deliver constant voltage with all 8 wind sensors.
- However there's the issue that the last two sensors hooked up are outputting higher voltage than the 0-3.3 V range that is expected. around 4 or 5V.
- When the current was higher these two sensors were getting much more hot than they probably should have been, at least much hotter than the other sensors.
- I checked the connections and tried changing the sensors that were plugged in but that didn't seem to change anything.
