Issues Encountered
- When all 8 sensors are plugged into the Lab Jack, the sensors output very small voltages. The voltmeter reads out a cycling voltage. It seems to be a problem with the power source.
- With the outlet by in the office it seems it can only deliver constant voltage to 1 sensor. More makes it cycle
- With an outlet by the lab bench, it can deliver constant voltage to 5 sensors. The 6th makes it cycle
Wed June 22
- Epoxied the flanges to the carbon fiber tubes
- To Do:
- Create/have made an assembly for 8-10 of the DB 9 cable connectors within the box for the lab jack
- Put together wiring for the power supply
Tues June 21
- Cut and filed more carbon fiber tubes
- Assemble 7 more of the wind sensors connected to DB9 ribbon cable in tubes
- Test that all of the electronics were working
Mon June 20
- Assembled shelves at storage unit
- Loaded U Haul with lab equipment
- Moved Equipment into storage unit
- Lunch at Shang Cho afterwards
- Honey Comb PB Pretzel ice cream
Fri June 17
- Got a lesson about screws, and read more about screws
- Installed lab jack software on Mac
- Hooked up one wind sensor to the LabJack to test it out while connected to the Mac
- Cut one carbon fiber tube in half and assembled one of these sensors with stands without any adhesive. It fits well, the ribbon cord needs to be pushed in.
- Need to learn how to write code to get from the voltage numbers to wind speed
Thurs June 16
- Mapped out the wind sensing system
- Completed online general lab safety course
- Completed online physics machine shop and Makerspace safety course
- Hooked up the hot wire anemometer to a voltmeter to test it out
- GND-White 5
- +9-12V -Violet 4
- OUT - Orange 2
- TMP - Green 3
- SHDN - Brown 1
- Like so:
- Knotted cable is ground
Wed June 15
- Met the group and learned the basics of some of the various projects
- Learned to use the coffee machine !!!
- Learned to solder and soldered right angle pins onto the wind sensors
- Set up a Mac mini
