7:05pm – Introduction to OBS Studio (Open Broadcaster Software)

Overview Results: Once you learn the software interface, the key learnings in dealing with the audio issues was a 2 step process. 1. Watching the activity lights to figure out what component (mic/aux) the capture card sound was coming from and 2. Setting that sound to come out to the speakers/headphones (where you want to hear that sound source). Which involved this (what I call) deep sound control panel setting.

7:45pm – Introduction to Animal Crossing New Horizons video game on Nintendo Switch

7:45pm – Tracking Weather Balloons

General discussion topics

  • 3D Printing projects
  • The speed of sound and the Hot Chocolate Effect
  • Making clear ice

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…)

Adventures in vacuum repair

When using the Shop-Vac the other day I noticed all the dust I was sucking up was being blown out the back of the vacuum… all over me.  Intrigued and filthy, I decided to investigate…

I emptied the vacuum and took the filter outside to knock as much dust and crud off of it as I could.  I employed the standard method of smacking it on the building and quickly twisting it back and forth in the breeze being careful to stay upwind so as not to breathe the fine and disgusting particles liberated.

When replacing the filter I immediately found the problem, or more accurately I didn’t find a key part of the vacuum cleaner.  The filter retainer was missing.  Without it, whatever the vacuum sucks up can shoot through the open bottom of the filter through the impeller and get blown all over me.  Fabricating a quick replacement from parts on hand took no time at all.  Sure, I could have bought the replacement part for $9 and had it next day from Amazon, but where is the fun in that?

I found a suitable scrap of 1/4″ acrylic onto which I traced the inner and outer diameters of the filter.

Using a jigsaw with a coarse blade I cut just outside the outer diameter.  Cutting acrylic or polycarbonate with a jigsaw (or CNC) can be tricky, friction heats the blade and the chips can weld the opening closed behind the cut as pictured here.  This piece was easily broken away with my hand, but I’ve had polycarbonate heal itself apparently stronger than the uncut material when cutting too fast without any coolant or compressed air to clear the chips.

Using a ruler and pen I measured and marked the center of the diameter along several angles.  Using the hammer and punch, I punched the mark for drilling (the dimple allows the drill to center more accurately).  This level of precision was not necessary but I find striking things with a hammer fun and habits like punching before drilling are good to reinforce.

I clamped the burgeoning new cover in the vise and drilled the center hole.  The bolt hardware is the ubiquitous 1/4″-20 (1/4 inch diameter, 20 threads per inch, super common stuff), so I’m going to drill the hole a little larger, 3/8″ to make it easy to slide on and off.  I don’t want to drill a hole that large to start with in the acrylic because it will catch a lot and cause chipping or cracking, so I started with a smaller 1/8″ drill and worked up through a couple sizes.

Now I need to install a mounting rod in the bottom of the vacuum cleaner.  Marking the center of the bottom of the vacuum cleaner filter holder was even easier.  I just connected the lines between the edges of retaining tabs on the outer edge.  This plastic is thin and soft enough to drill directly with the 1/4″ bit.

Then I installed the filter holder pin by putting a 4″ 1/4″-20 bolt through a lock washer, then a fender washer then fed it through the hole from behind (from the vacuum cleaner side) to stick out the bottom.  I followed that with another fender washer, a lock washer and a nut.  The fender washers sandwich the plastic to spread out any load and prevent cracking around the hole.  The lock washers keep the nuts tight even under the vibration of the running Shop-Vac.

The filter slides over the outside, and the cover slides over the bolt to seal it in place.  Another fender washer, lock washer, and convenient wingnut secure the assembly with a good tight seal.

At this point the filter replacement was functional but by no means done.  Workshop88 is a makerspace, and that means nothing is done unless you’ve used the laser or a 3D printer, so Christine engraved the lid.

Voila!

I could have easily ordered the appropriate replacement and had the fresh new part the next morning, but by creating one myself I get the satisfaction of a job well done, and I was able to vacuum up the acrylic chips from the jigsaw and drill right away.

We’re Hackerspace Passport Ready!

PageWstamp3788Thanks to the laser cutter, we now have an official rubber stamp, and we’re ready to provide Workshop88 visit chops to all our visitors with Maker Passports!  OK, as soon as one shows up.

Stamp3787But we now have the capability to make our own precision rubber stamps!  Rubber stamps.  Yeah, like in the paper-based olden days.  Well, I thought it was cool.

Some more details here.
