Workshop 88 Weekly Maker Night – November 17, 2020

Introduction

Workshop 88 is a makerspace in Glen Ellyn Illinois. We are more than a workshop, we are a growing community of creative talented people who aspire to learn and share their insights, experiences, and projects.

  • Tom Matukas
  • Gail Jo Kelly
  • Daniil Bystrukhin
  • Peter Fales

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.

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…)
