I like to make wearables and laser random things. I have been a member since March 2012 and really have a good time at Ace Makerspace My background is in front-end developments and design. I currently work as an independent consultant doing all manner of things.

Introduction Ace Booking v1

Ace Booking is the custom open-source software we developed to support us operating in a COVID safe way. This software supports:

  • Occupancy limits in each room
  • Members booking the time they need
  • Occupancy Tracking in case of exposures
  • Remote staffing

We couldn’t ethically consider re-opening without it.

What’s New

There are many upgrades and changes to how the software looks and works.

  • You can now book in 15 min. increments! You no longer have to book by the hour
  • The user interface is very different, now choose your start and end time and the system can tell you about availability
  • The user interface now has a calendar view. If your desired booking isn’t available you can check and see the next closest availability.
  • The late check-in window changed to accommodate the new 15 min. windows.
    • You can check-in 5 min. before your booking (if space is available)
    • You are considered late at the 5 min. after your booking mark and will start to get notifications.
    • You are considered as ghosting at the 15 min. mark after your booking, if you haven’t checked in, and your reservation will be canceled and the space made available for others. (you can always do a new reservation.
    • You will get a notification via email and slack reminding you to check out starting 5 min. before your expected check out times.
  • New remote staffing controls include
    • The ability to book spaces for maintenance without having to make personal bookings.
    • The ability to cancel user reservations for maintenance blocks
    • The ability to remote checkout people who didn’t check out
    • The ability to make bookings for members on maintenance crews
    • Reports on use trends

What to do if things break for users

While the team did our best to anticipate how folks could use or break this software there may still be a glitch or two. And we know our members are some darn creative users. If our members have trouble or the system doesn’t’ behave as anticipated they report the issue on slack and include photos if at all possible. Report on #general or #amt-software

laser etched rubber stamps

Adventure in Rubber Stamp Making

So Ace is working on a holiday card and we need rubber stamps for some of the art. This is the tale of making rubbers stamps including all the mistakes on our 100w CO2 Laser.

Materials used

  • Scrap wood
  • Gorilla Spray Glue
  • Craft Foam
  • Art Ink pads
  • Laser Engravable Rubber Polymer, low odor, from rubber-stamp.com

The artwork

The artwork… that is the first place things went wonky but I didn’t realize it until I cut. I had forgotten that engraving needed an outer boundary in order to drop out the right stuff. Check out these screenshots. Everything black in these images will be burned away.

The thing to remember with vector laser files, LaserSoft, and rubber stamps is:

  • Mirror the art
  • Set an outer boundary for the etching
  • The outer boundary is the same as the cut line so you will need one object to be the boundary and one object on another layer to be the cut line.
laser art
In this file, I forgot to put an outer boundary for the vector etching and that means all the white bits between the pink cut line and the inner art is what will print when I stamp it. Not ideal.
Laser art
In this one most of the art is correct and all the inner graphics that are white will print. The only thing that is wonk is the white gap between the pink cut line and the etching. That is easily solved though post-laser with a pair of scissors.

Opps… etched away the thing I wanted to stamp.

Here are the results from the two files. As you can see the art in the first file didn’t match the intention.

Testing and getting the right settings down

The laser polymer comes with some settings but they are for much lower wattage lasers than ours.

settings from laser package

It took a bunch of test etching to get to settings that worked. I used a focus range for etching. These are the settings we finally settled on:

  • Cutting: 15/90/87
  • Etching: 150/80/78 (make sure to turn on grade engrave)

Putting it together and what I learned about glue

So I cut the outlines out of some scrap wood and used e6000 glue to attach the rubber bit. The results were… bad.

Hard curled up crumbling stamps.

The final product did work out well with a layer of craft foam and using gorilla spray glue.

The post-laser etching finishing and clean up

Laser etching rubber polymer is dirty. Really dirty. When the stamps come off the laser they should be soaked in the water right away for about 10 – 15 min. then scrubbed with a soft brush.

This is what a brand new filter looked like after 8.1min. of cutting and etching laser.

Anti-Racist Education for Makers

Ace is thrilled to introduce 4 workshops in October that explore how to be anti-racist in our maker communities. Working with an amazing peace activist and facilitator, Emily Bowen, these workshops have been crafted to be broadly relevant to the maker community and Ace Makerspace specifically. 

Schema of Makers

Sunday, October 4th  |   Noon – 1pm PST

$5-20 sliding scale  |  Tickets

Who defines what a legitimate maker is? Explore how different types of makers are valued and have influence in how the community is shaped.

Communities are like ecosystems — living things that change and evolve over time. We will unpack different maker identities and the dynamics of those identities and their influence on how our makerspace community has evolved… for good or for ill. This workshop will explore both what the identity of makers have been as well as explore what it could and should be.

Maker Say What

Sunday, October 11th  |   Noon – 1pm PST

$5-20 sliding scale  |   Tickets

How the language we use to share maker knowledge interacts with race.

When it’s easy to lean into jargon as a way to communicate intelligence and experience, one can quickly conflate the words we use with who belongs and who doesn’t. And when it comes to talking about issues of race and gender, there is often a fear of saying the wrong thing. This workshop will explore how to be inclusive with Maker speak, as well as how to avoid the pitfalls of inaction by the fear of talking about race imperfectly.

Taking Care of the New Guy

Sunday, October 18th  |   Noon – 1pm PST

$5-20 sliding scale  |   Tickets

When the new guy isn’t white or a guy. We will explore where there is an opportunity to connect with people different than ourselves. 

Black people, and other people of color as well as Indigenous individuals, generally experience trauma because of microaggressions or just a lack of welcome in majority-white spaces. So to do female, femme, non-binary, and gender-nonconforming folx in majority male spaces. How then do we take care of new individuals when they are not like us or having a much different experience in the world.  This workshop will leave participants with a checklist to do just that including positive accountability.

You’re Too Comfortable

Sunday, October 25th  |   Noon – 1pm PST

$5-20 sliding scale  |   Tickets

Recognizing when comfort is an indicator of white supremacy manifesting itself. Explore how to take action when it does.

One way whiteness protects itself is by eliminating stressors of those who are in proximity to it. Things are easier, quicker, more accessible, more abundant, less risky, and more. This workshop will examine how comfortable you are and explore where your own discomfort might be putting up barriers to equity and inclusivity. Then we’ll talk about what can be done about it. We will uncover what actions can be taken when we discover white supremacy manifesting itself.

More about COVID Safety

In Order to stay COVID safety, we do much of the teaching using a “jumbotron” to project lessons on the wall. We also ask that all students take the COVID-19 safety course and masks are required.

Hack your mask with valves

The “dirt-bike” or sports dust masks are really popular. A lot of folks know them from using them at events like Burning Man and Coachella. The issue with a lot of “dirt bike” style masks is the exhalation valves which are totally unfiltered. This makes these masks pretty useless for COVID-19 safety. You can read more about what the CDC says about masks with valves.

Everything I used for this 2-min hack:

  • CLUX Mesh Black Face Mask with Black Carbon Filter by Continental Luxury (amazon)
  • small (not tiny) rubber bands – one for each valve
  • Scissors
  • Non-Woven Polypropylene Fabric (woven fabric will work too)

I assembled the mask according to manufacturers’ directions. I cut the filter fabric to go over the valve with a very generous overlap – you can always cut off the excess. Then I slipped the rubber band over 2 layers of filter fabric to secure it to the Valve. This covers the valve and any leaky spots around the opening.

Respirator Hack for Covid

So the issue with a lot of respirators and dust masks is the exhalation valve which is totally unfiltered. This makes them pretty useless for COVID-19 safety. You can read more about what the CDC says about masks with valves.

Everything I used for this 5-min hack:

  • 3M Rugged Comfort Half Facepiece Reusable Respirator 6502QL (Medium)
  • Electrical tape
  • Scissors
  • Non-Woven Polypropylene Fabric (woven fabric will work too)

Check out the gallery below to see how I added a filter to my valve. I specifically added it to the outside so it would last longer before getting moist and so others could see it. I used two layers of material for the filter.

New Habits for Keeping Safe

The new reality around COVID-19 safety has us all scrambling to create new habits while we go about the business of making things. We are currently trying and experiment with tool caddy’s. The idea is:

  • Come into the shop, and pick up a caddy
  • As you use hand tools put them in the bucket
  • Once you are done sanitize them and but them back

This way you don’t have to stop and sanitize with every tool and we avoid cross-contamination. Each bucket also has a small spray bottle of surface sanitizer and a personal pump bottle of hand sanitizer.

We are not sure if it will take all the sting out of the needed cleaning. We will see where the experiment leads!

AMT Members in Action with Covid-19 Relief efforts

We are slowly learning in a community that this thing will be a marathon not a sprint. So we are setting ourselves up with safer workspace practices to continuously offer the best most immediate help we can. We are also learning to celebrate everyone’s efforts even when is just nibbling at the problems.

Without further ado here are just a few snapshots of AMT members in action while we work to help people directly and in partnership with our fellow makerspace and non-profits.

Making DIY PPE: Best Practices for a Safer Makerspace Workplace

Disclaimer

While we have done our best to collect information from reputable sources, we are not industrial hygienists or medical professionals.  We are doing our best to be helpful in a crisis situation. These guidelines are provided “as-is” and come with no guarantee that following these guidelines will keep you 100% safe.  Use at your own risk, use combined with your own judgment, and refer to the latest scientific information available.  

Introduction

In the past few weeks, Makers everywhere have stepped up to help deal with the COVID-19 pandemic by making Personal Protective Equipment (PPE) to help keep healthcare professionals and other vulnerable people safe. However, makers becoming sick themselves, spreading the disease, and contaminating their workspaces adds to the problem and not the solution.  We are providing these best practices, gathered from medically reputable sources (such as the CDC) in an intent to provide a means of decreasing the risk of makers spreading and contracting COVID-19 while in the process of making DIY PPE.

Access control

It is very important that you control and track who is in the makerspace and when. The following is practical advice.

  • Keep isolation protocols. If people are not already living together they should not be working in the same room without masks being worn at all times. 
  • Keep 6 feet away from each other in hallways and common spaces.
  • Sanitize items handed off between individuals as much as possible
  • Make sure all people in the space making PPE are trained in the protocols for your space before allowing access (example: AMT COVID-19 Access Protocols – will link)

Personal Safety

  • First and foremost, please do not attempt to make any PPE if you or someone in your household is sick. Even if you have a small tickle in your throat, please do not make any PPE if you think you, or someone that you are exposed to may be sick.
  • Act as if you were infected by the COVID-19 virus. Wear a face mask and a fresh pair of gloves when collecting each piece of ready-to go PPE. Store the PPE immediately in a sealable bag.
  • Keep your distance: Remain no closer than ~6ft (2m) from another human
  • Wash hands for at least 20seconds with soap and water before beginning work or handling materials.
  • Don’t touch your face
  • Cough or sneeze into the crook of your elbow 
  • Sanitize your work surfaces and tools before and during PPE creation
  • Sanitize your cleaning equipment when washing fabric PPE and PPE materials

Workspace Hygiene 

    • If you can, please segregate the tools and equipment that you will be using to make the PPE in your space away from people, pets, bathrooms, or food preparation surfaces.
    • Always disinfect between users.
    • There is still debate about how long the virus survives on hard industrial surfaces, but it is currently estimated that COVID-19 can live on hard industrial surfaces (metal, plastic, and glass) for up to 3 days. If you have access to sanitizing solutions, including diluted bleach, 70% alcohol solution, or products like Star-San or Odo-Ban, please disinfect your tools and equipment before and after each item is made. You can also let packed items sit for 3 days before distributing, as another mechanism to reduce the risk of transmission.
      • For 3D printing:
        • If the machine is clean, the plastic is heated up enough to be considered clean once the print is finished.
        • Do not attempt to sterilize the finished part; just drop in a clear bag with gloves or tongs and set aside.
        • Many sterilization solutions will damage PLA, and off-the-shelf isopropyl alcohol is not concentrated enough to clean the parts
      • For sewing:
        • Store similar to N95s (allowing the mask to hang in a designated area or placed in a paper bag and labeled – with one mask per paper bag). 
        • Launder after each use. 

 

  • Do not use bleach to sanitize metal equipment or tools as it will corrode most metals.

 

If Someone Gets Infected: Clean & Disinfect

Source: https://www.cdc.gov/coronavirus/2019-ncov/community/organizations/cleaning-disinfection.html

 

If someone working in the space displays symptoms or is tested positive for COVID-19, the workspace must be thoroughly cleaned and disinfected to avoid further spreading the virus to others.

Cleaning and Disinfection After Persons Suspected/Confirmed to Have COVID-19 Have Been in the Facility

Cleaning refers to the removal of dirt and impurities, including germs, from surfaces. Cleaning alone does not kill germs. But by removing the germs, it decreases their number and therefore any risk of spreading infection.

Disinfecting works by using chemicals to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs. But killing germs remaining on a surface after cleaning further reduces any risk of spreading infection.

  • It is recommended to close off areas used by the ill persons and wait as long as practical before beginning cleaning and disinfection to minimize potential for exposure to respiratory droplets. Open outside doors and windows to increase air circulation in the area. If possible, wait up to 24 hours before beginning cleaning and disinfection.
  • Cleaning staff should clean and disinfect all areas (e.g., offices, bathrooms, and common areas) used by the ill persons, focusing especially on frequently touched surfaces.

Surfaces

  • If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.
  • For disinfection, diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective.
    • Diluted household bleach solutions can be used if appropriate for the surface. Follow manufacturer’s instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted.
  • Prepare a bleach solution by mixing:
    • 5 tablespoons (1/3rd cup) bleach per gallon of water or
    • 4 teaspoons bleach per quart of water
    • Products with EPA-approved emerging viral pathogens claims are expected to be effective against COVID-19 based on data for harder to kill viruses. Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method and contact time, etc.).
    • For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove visible contamination if present and clean with appropriate cleaners indicated for use on these surfaces. After cleaning:
      • If the items can be laundered, launder items in accordance with the manufacturer’s instructions using the warmest appropriate water setting for the items and then dry items completely.
      • Otherwise, use products with the EPA-approved emerging viral pathogens claims (examples at this link) that are suitable for porous surfaces 

Linens, Clothing, and Other Items That Go in the Laundry

  • Do not shake dirty laundry; this minimizes the possibility of dispersing virus through the air.
  • Wash items as appropriate in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry that has been in contact with an ill person can be washed with other people’s items.
  • Clean and disinfect hampers or other carts for transporting laundry according to guidance above for hard or soft surfaces.
