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.

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…)

Workshop 88 Open House

May 16, 2019

Workshop 88 has an open house every Thursday from 7:00pm – 9:00pm where we welcome visitors and give shop tours. If you would like to see what’s available and what’s going on at your local makerspace or if you’d like to talk about a project you have in mind, come check us out!

As a result, Thursdays also are typically our most social night too. This week we had members working on many interesting projects including metal casting preparation, 3D printing, CNC milling, electronics, and more.

Here’s a look…

More projector fun! (see previous blog post for more details)

3D printing a space ship model to create a mold for a bronze casting

Bronze casting from the PLA model.

Meanwhile GailJo was 3D printing weatherproof sign components for illuminated Workshop 88 signs. The signs were so effective someone stopped by to check us out within 2 hours of them being placed!

I love when we have two or more 3D printers working at the same time. If you’re curious about 3D printing check out our step by step tutorial here.

Cutting up bronze casting scraps so they fit in the crucible for another casting. We used the band saw, bolt cutters, a ball peen hammer, and a vise. Copper is soft, tin is soft, mix them together you get bronze. Bronze is hard… really hard.

Jim is working on stepper motor driver electronics for a kinetic sculpture.

CNC’ing a cubic hole in a graphite block to be a mold for a future silver cube casting.

(Actually hybrid manual/CNC control in this case.)

All are welcome, we hope to see you one of these Thursday nights!

W88 at River Forest Maker-Fest

Workshop 88 joined many other makers at the River Forest Public Library’s first Maker-Fest on 10/7/17. The Drawbot got lots of attention, and decorated the shelves with its drawings.

While maker events and makerspaces are a growing phenomenon at libraries, and River Forest has considered what it can do, its beautiful old building just doesn’t have room for a space.  But Ethan Baehrend, as part of his Eagle Scout mission, encouraged the library to host this Fest, both to provide a maker event for area residents and to help the library gauge interest so it can best serve its users.  The event was a success on all fronts.

Ethan posed here for a picture with the Drawbot’s rendition of the Eagle Scout logo.  Thanks to his mom, Diana, for the picture!

The Drawbot was in good form with its new aluminum-and-teflon pen holder, and generated lots of artwork, as well as interest among visitors. Here are some pics of its output.

 

Some more details on the drawbot are here.

Winfield Library Build-A-Flute Workshop

Workshop 88 led a workshop on 7/11/17 for the Winfield Public Library Young Adult Services called Science of Sound. The students built flutes (more like recorders) out of PVC tubing and pieces of wooden dowel. The flutes worked quite well, and the students had a good time.

There’s a LOT of information on the web about PVC flutes, up to and including some “flutomat” pages with interactive spreadsheets for finger hole placement. Who knew?

In preparing for the workshop by making a couple of flutes at home, it quickly became clear that it was often easier to get a flute to sound the first overtone than the fundamental we’d be shooting for. To set the stage for discussing that as the student flutes made their first noises, the presentation started out talking about natural vibration modes, with demos of guitar string harmonics, vibrating strips of metal, and a 15-foot “jumprope” with standing wave loops up to the 4th harmonic.

In discussions at W88 before the class, Rachel pointed out that decorating the flutes would be important to some students. Colorful duct tape, provided by both W88 and the library, proved that suggestion to be quite true, despite the stodgy old teacher never even considering it. Thankfully, we have a community to help rip off blinders!

Those discussions also resulted in scope creeping from the initial plan of just showing that drilling a hole or 2 could change the pitch of the flute. The final class version used a traditional six hole fingering scheme that played fairly well in tune into the second register – a few notes above an octave. Thanks to this flutomat for the hole spacings!

CAD CAM tutorial

CAD CAM tutorial
by D.  Scott Williamson

This tutorial will show you how to use Computer Aided Design and Computer Aided Manufacturing or CAD CAM tools to create and preview a Gcode file of the Workshop 88 logo that can be run in a 3 axis CNC Mill.

Background

There are 5 main types of machine operations

  1. Engrave (follow path): The tool tip will follow the 3D path provided.
  2. Profile: The tool edge will follow either the inside or outside contour of a path down to the specified depth.
  3. Pocket: The tool will remove all the material within a contour down to the specified depth.
  4. Drill: A drill routine will be executed at each point location.  Drill routines come in 2 flavors:
    1. “Peck” used with drill bits, drills to successively deeper depths liftig the bit out of the work regularly to clear chips from the flutes.
    2. “Spiral” used with endmills that are a smaller diameter than the finished hole.
  5. 3D relief: The tool tip will remove material above a 3D surface usually specified in a 3D model or a 2D height map image.  There are two main modes:
    1. “Waterline” similar to inverted pocket operations where bulk material is efficiently removed outside the 3D model to a number of stepped depths resembling waterline in a topological map.  Typically used in a first pass with a large roughing bit to remove the bulk of the material.
    2. “Raster” moves the tip of the bit smoothly over the model in a raster pattern.

Gcode is a “numerically controlled programming language” which is why a Gcode file extension is typically .nc.  It is a human and machine readable text file.  You will rarely if ever need to look at or edit the Gcode.

Overview

This tutorial will demonstrate Engrave, Profile, and Pocket operations, which are the most popular.

There are 4 steps to this tutorial:

  1. Create a .svg file containing paths needed for machine operations
  2. Create machine operations
  3. Export Gcode
  4. Simulate, visualize and validate

Tesla Coil demonstration on September 17!

img_8371
Workshop 88 member Phil Strons will be giving a demonstration of his Tesla coil at Workshop 88 this coming Saturday, September 17th, from 1:00 to 5:00pm.

Here’s what Phil has to say about what to expect from this demonstration: “Last year I had 20-inch sparks, but I’ve since done some modifications & repairs. I’m hoping for closer to 30-inch long sparks this time.”
WARNING – This device generates electric fields with high voltages of 1,000,000 Volts or more and has potential to interfere with medical devices such as pacemakers.
