Show & tell time!
Each session will target 10 minutes for show and tell and 5 minutes for Q&A
7:00pm – Scott will share his Schlieren photography setup. Schlieren photography allows you to visualize changes in air density and used to see airflow, temperature differences, shock waves, or sound.
7:30pm – Rick will share his experiences with the STMicro accelerometer, magnetometer, and gyroscope leading into a discussion about creating a tilt compass using trigonometry.
- Accelerometer, gyro, compass
- Gimbal lock (Gimbal lock Wikipedia)
- Temperature, humidity, and pressure
- Pressure sensor and altitude detection
General discussion topics
- How would you calibrate an anemometer?
- Jim Williams: Drive a car with it out the window on a stick to get outside of the car’s air-stream and have a copilot record rpm and car speedometer. (Scott added: In both directions to factor out a gentle breeze)
- Mark Frost: Put it on the end of a stick and spin at a known rate in a still room to know airspeed of the sensor.
- Scott Williamson: Connect it to the end of a tube connected to a large plastic bag. Place the bag in a box of known volume, place a second slightly smaller weighted box on top of the bag within the first box to construct a piston. Measure the time it takes to move the known outer box volume of air through the tube of known diameter to estimate the airspeed. Repeat with different weights.
- Andrew Morrison: Why does an accelerometer measure an acceleration when it is not moving or changing velocity?
- Rick Stewart: Laser Nanny repair
- Did not cover:
SMD soldering tips – (flux, solder paste, iron, iron tip, hot air, temps…)
