Greg Fridman of AA Plasma answers our questions about plasma and real world applications. He also chats with us on our podcast this week.
I’m a research and development engineer focused on atmospheric pressure non-equilibrium plasmas for the catalysis of various chemical processes. In other words, our team works on controlling chemical processes for energy, environmental remediation, agriculture, and medical industries. For example, we use non-equilibrium (“cold”) plasma to disinfect fresh produce before packaging it to provide you with pathogen-free lettuce.
We work with our industrial partners who have a poorly or partially solved problem. For example, a large-scale bread bakery produces excessive alcohols and other volatile organic compounds (VOCs). Today they burn this polluted air with natural gas, producing CO2. We can do this with plasma at comparable CAPEX (capital expenditure), slightly higher OPEX (operating expense), but without the excessive CO2 emission.
Our main lab is just outside the University of Pennsylvania’s campus, near 38th and Grays Ferry Avenue in Philadelphia. We partner with local universities to perform some of the more challenging plasma and materials diagnostics. We also partner with regional manufacturing partners to work on some of our more significant projects.
Me? Well, I was born into it. With both mom and dad in academia, I had Ph.D. students as my babysitters for as long as I can remember. But I really started making cool stuff at the Moscow Chemical Lyceum when I was around 14. At that age, oh, but of course, my primary interest was in making lacrimators and explosives.
I’m 43, so 30+ years, give or take. My interests evolve, though. I’ve worked on commercializing cold plasmas for about a decade.
After a decade of studying plasmas and publishing 50+ papers (with about 10,000 references), I wanted to make something useful for humanity. I think some call it “commercialization.” Here’s my Google Scholar link, by the way: https://scholar.google.com/citations?user=fNk59nMAAAAJ&hl=en
All of you! Especially those of you who publish YouTube video explainers. I am forever grateful to the YouTubers who taught me how to pour epoxy tables, MIG and TIG weld, etc. When working on a new problem, I usually watch a dozen hours of videos on how others have attempted this.
We are building something we call “Cold Plasma Studio” (in a few months, we should have our website up: https://coldplasmastudio.com/). The Studio will be a maker collective with a focus on the applications of cold plasmas. I’ve been dreaming of a solid, white-walled warehouse with epoxy floors, and we are now working on this 22,000 square foot beast, just 4 miles from the University City. Stay tuned!
Stay awesome! Don’t give up and keep making incredible stuff!
Oh, a trick question?! You mean beside our own? I met NextFab at the Maker Faire, so I’m going to go with that one. But the robot dogs and the drones were pretty awesome. I think the Cocoa Press 3D chocolate maker exhibit, next table to ours, is fantastic: https://www.cocoapress.com/. Finally, I thought the handwashing game for kids is the way of the future: https://www.higenemonkey.com/!
Too many to list. I’m a talkative type, and I did lose my voice by the end of the Maker Faire.
When I see it break BUT I know why it failed and have a great idea how to fix it! It’s incredible when there is a light at the end of the tunnel.
This was a fun interview, thank you. I am happy to do this again. Those of you who have questions, please feel free to reach out to me at greg@aaplasma.com or @gregfridman on the socials.

Today Madeline Rile Smith of Mad Hot Glass answers our questions. She goes into more detail about her art and her process on the Philly Maker Faire podcast.
I make lots of different things out of glass, such as interactive sculpture, musical instruments for multiple people to play at once, absurdist devices for performance art, installation, and video work. All of my work is tied to my interest in human connection and the way that connection with other people can help and hinder us, as well as helping and hindering the human body.
Much of my work I make for myself. I am inspired by imagining what I have not seen yet, so I want to pull it into existence. I will often get an overwhelming urge to create a new piece when I have a weird idea- and need to create it simply so I can see it in front of me.
I am located in Chestnut Hill, Philadelphia.
I began working with glass in 2008, when I was in high school at the Crefeld School in Philadelphia. This changed the trajectory of my life completely as I never thought I would be a visual artist, but I fell in love with glassworking and decided to devote my life to it!
I’ve been working with glass for over 13 years. We’ve been together a while, but the fire is still there!
I’m inspired by relationships and interpersonal dynamics, and attempting to make a physical representation of them. I’m also inspired by the way hot glass moves, and how it is able to be manipulated in seemingly infinite ways.
I’m inspired by artists of the Performance Art Movement, and Body Art Movement, especially Rebecca Horn and her body extensions, and Marina Abramovic.
I want to keep making, do more live performances with new glass pieces, and I’m working on setting up a new studio in my home.
Nobody is ever only one thing- I’m curious how other makers balance all the different aspects of their lives. Also – does anyone want to collaborate on a new performance?!

An American Tale of Freedom’s Promise by Patrick McFadden is a “historical fiction novel about the struggle for American Liberty from the British Empire, covering the early years of the Revolutionary War surrounding the Declaration of Independence in 1776. The early war provides background, yet the true conflict is between a diverse set of spies, all Americans, but whose loyalties are split between the British and American causes.
My first book is a historical fiction covering the early years of the Revolutionary War, utilizing an interesting, and often true story, that will hopefully help young Americans learn and remember what actually took place between 1775 and 1778. This historical fiction story will likely be the first in an extended series. I am also working on outlines of other historical fiction stories, European and American. Historical fantasy and science fiction works are future possibilities as well, and I have started outlines in both genres.
Again, I really hope to help educate teens and young adults about the rich history in our region, and the story is a solid chronological history of the early American Revolution that may be educational to the wider American reader.
I am living in and writing from Bucks County, where much of the story is placed.
This is my first book, begun in Spring 2020.
One of the inspirations for the book are the journals of Captain Johann von Ewald, published in 1979, Yale University Press. Reading first person accounts provides a perspective unvarnished by the sentiments of modern scholars, authors and historians. As mentioned below, the contrast of the accounts by Captain Ewald and John Graves Simcoe, as well as their respective conduct during the war, is enlightening.
I hope my story helps students realize that neighbors opposed each other in many instances, but that this is a human story, and that there were displays of both civility and atrocity during the war by both sides. Johann von Ewald and John Graves Simcoe are a contrast in this regard. Like the art works of William Ranney, I hope readers will get some sense of the common person’s life during the 18th century, and that there was something worth fighting for. Life expectancy was low, as 50% of children were not likely to survive or foster productive families, but those that did survive had a good chance of living a life that few common born people, worldwide, would enjoy.
And the characters in this story have lives that will go on. Hopefully, that means more books in this series, as they seek out a piece of the American dream.
An additional point, I hope the book imparts the concept that the American Revolution, as exemplified by the 2nd Continental Congress, wasn’t just about successful middle aged white men. Much of the fighting was done by boys and men in their teens and twenties. The American population was very young, like many revolutionary movements in history.

Lisa Shaffren runs “The Creative Engineering Fabrication Lab (CrEF Lab) at Crefeld is the school’s makerspace, and one aspect of a robust maker-ed and experiential-learning-based program. CrEF Lab is a culture-first makerspace, committed to expression of all voices and engagement of all students, and especially those of young women and young people of color whose perspectives are often underrepresented in STEM fields and maker spaces.”
Lisa answers questions about the lab and chats with us this week over on the podcast!
I am the Program Developer and Lead Teacher of The Crefeld School’s makerspace, CrEF Lab, which stands for Creative Engineering Fabrication Lab. I designed & created the lab in collaboration with the school’s admin team. Designing and creating the program itself is a constant creative project, and I am constantly learning, researching, and iterating.
The design of the program and the makerspace is to serve students, but I also become inspired by and addicted to both the work of designing the program, and the individual program components. Some of the software for video game design, 3D CAD, or animation is incredibly absorbing. I love to solder and do microcontroller builds, but lately, I have been especially absorbed in playing with DAWs, especially Ableton Live and the visual programming language Max8 within Ableton. My excitement gets transferred to the students and makes me a better teacher. We are a culture-first makerspace, and we work hard to explicitly invite students who identify as members of groups underreprested in STEM- so, students who identify as female, non-binary or transgender and students who identify as Black, Indigenous, or People of Color. We work with the organization Beats by Girlz to invite more young women into digital music, which can also begin a path toward other kinds of technology and computer science. We are lucky enough to have some PUSH2s, by Ableton, as well as some Novation MIDI controllers, and students have been very excited to play with them, and with DAWs in general.
I have always kept notebooks and lists of ideas, especially ideas that are intersections between genres, and been creative in an intense way that is different from most people I know. I only moved into my role as CrEF Lab Program Developer a few years ago, and since then, have been developing the program.
I started in biology because I wanted to be a vet, but it turned out that it never really spoke to me. I found computer science & creative software later. I wish I had found it sooner. It wasn’t something I had much exposure to as a young person, which is one of the reasons I am excited to make it available and accessible to students.
Our program is very much student-driven, and my students are a constant source of inspiration to me. I take many of my cues from them about what directions to expand the program, and that gets mixed with my own influx of research, ideas, and inspirations. For example, last year as we were forced into more digital and virtual spaces, our program grew especially in the areas of digital animation, video game design, and 3D CAD using the software Blender, because many of our students had strong interests in those areas. The school’s philosophy and approach really support that flexibility.
The Crefeld School also has a smart, talented staff, and the arts department has some gifted artists, so I pull a lot of energy and excitement from my interactions with other staff; it’s the kind of creative environment where a casual conversation about something unrelated can spark an idea for a project or new piece of curriculum. Because everyone is working toward the same mission, the different perspectives and skills of different staff members is this constant fuel for creativity. It’s an inspiring way to work.
I have also done a large part of my learning and training with Drexel University’s ExCITe Center, where I was teacher in residence for two consecutive summers.
ExCITe stands for Expressive and Creative Interaction Technologies, and within the center are the MET Lab- Music Entertainment Technology, and EGS- Entrepreneurial Game Studio. Each of those labs has had a big influence on Crefeld’s maker program, which includes a game design program originally developed in collaboration with EGS and expanded from there. In addition to our usual game design electives, we are currently working with former EGS Program Manager Corey Arnold, and Shawn Pierre of Philly Game Mechanics, to offer 8-bit video game design courses for middle school and high school age groups. We’d like to help expand access to high-quality STEAM and CS programming to students outside of our school community, and this is a step in that direction.
We also have a just-forming digital music program that evolved out of my excitement for the learning I did with MET lab, where I spent most of my time during my summer at the ExCITe center. The program is also infused with music in many ways; we have a little moog synth that was recommended to me by MET lab staff Jeff Gregorio, who also does incredible work with intersections of music & technology, I used ExCITe materials to create a project-based curriculum unit about the physics of sound for STEAM integration, and many of our microcontroller projects and even some of our soldering and electronics projects are connected to music in some way. My go-to microcontroller is the teensy, which has MIDI capability and capacitive touch sensing built in. I had an advanced student use an Adafruit kit to build a little synthesizer in an altoids-can.

This week we’re catching up with Christopher Sweeney to find out what he’s up to as an educator and to get the low down on his MycoLights. In 2018 Christopher answered our questions here and he goes in to more depth on our podcast this week about growing lights from mycelium.
I enjoyed the variety of the exhibitors at the last Faire, but I have to say anything that was truly DIY I saw was my favorite.
Talking to people I know from social media, always nice to meet face to face.
During the beginning of the pandemic, being able to 3D print pieces for the healthcare workers, as well as hat clips for migrant workers in California. Besides that, being a finalist in DesignPhillys’ “Best in Emerging Design” show for my MycoLights this upcoming October.
Being a finalist in DesignPhillys’ “Best in Emerging Design” show for my MycoLights this upcoming October, teaching, and working on hydroponics and irrigation systems using Micro:bit and Chibitronics micro controllers.
I created a DIY forge, and was into casting pewter in my backyard. I also took a class at GenSpace and learned our bioluminescent fungi and bacteria, so that was something new and amazing I did in 2020. I did many other fabrications (as well as etching copper plates for printmaking) using the Glowforge once I was teaching my students in a hybrid mode. I had some down time in 2020, so lots of things were explored.

This week we’re chatting with Jono Matusky from Plynth. Jono was our Maker Wrangler for the faire in 2019 and has been working on a new app to connect physical and digital content. He answers our questions below and goes in to a lot more depth on the podcast.
We make Plynth – an app that uses image recognition to link artwork to digital content. Viewers can snap a photo of the art to learn more, access exclusive content or go behind the scenes. Like a QR code, but cooler.
Creators, generally, but more specifically anyone who makes both digital and physical artwork that they’d like to bundle together–musicians, digital artists, galleries, etc.
Philly!
I remember getting a book on origami when I was a kid, but I couldn’t do all the folds because I couldn’t read yet. It’s been a while!
See above!
I was doing watercolor paintings of my record collection and wanted a way to like the art to the music. That’s where the idea first wiggled its way into my brain.
Anyone who’s trying to make their dreams a reality. I’m especially inspired by other Philly makers like Oat Foundry, Cocoa Press, Pop Up Polaroid, Junto Bikes, Alternate Devices – too many to list!
We’re trying to get more users to try out Plynth. If you’re interested, sign up or let us know!
Want a free postcard? In addition to Plynth, we also run Postcard Mixtapes, where we partner with organizations around the world to put together a Plynth-powered mixtape featuring artists from their city. Get a free one here.
Loved the giant fire-breathing pterodactyl from my friends at PXL LAB.
It was a great way to get engaged with my fellow makers (especially as the Maker Wrangler).
Seeing it actually happen! After a year of hard work, it was incredibly rewarding.

Keisha Whatley of Custom Arts Studio joins us on the podcast! Go and listen to her inspiring journey and the exciting new ArtHaus project she’s spearheading.
Custom Arts Studio is a full-service fine art & design company. We create/make paintings, illustrations, portraits, murals, we paint on bowling shoes, basically anything our clients come up with, if we can, we get it done for them CUSTOM. We also provide graphic and web design services for local and country-side small businesses. Branding is our specialty and we have created a 3-step process that ensures company’s logos reflect not only their product but their core values as well.
Our clients run the gamut from someone who wants a portrait created for their mother to a multi-million dollar development corporation. Our mission is to make high-quality fine art & design accessible.
Our commercial studio is located in East Mt. Airy. We just acquired the new location for the Germantown ArtHaus in April of 2021 in Germantown.
As far back as I can remember. I returned to making in 2014 after an over 15 year hiatus and haven’t stopped since!
AS far back as I can remember. My mother always encouraged my art making and I was often in summer and weekend art classes. I attended the Creative and Performing Arts High School and majored in Visual Arts. It was there that I fell in love with oil painting.
I am inspired by old-world Renaissance painters Michaelangelo and Carrvaggio and more modern artists like Basquiat and Philly’s Serena Saunders (@mspassionart) but also the dreamer that works all day for a job then comes home to work all night on their dreams. They inspire me.
The Germatown ArtHaus is what’s next for me; creating opportunities and stages for others to be successful on is directly in line with my life’s mission “to make everything around me beautiful, and THAT be my life.”
I would ask… what do you need? What is missing in your toolkit that, if it were there, would make the most difference in both your success as a maker and your experience of who you are as a maker.
I think my best moment as a maker was when I finished a painting for an exhibit that I was basically doing for free early in my “art as a business” career. I really didn’t have the extra 62 hours that it took to create the piece but the theme and the exhibit location spoke to me. I did it for the spirit of the project. I remember the moment I stepped back from the “Queen” Culture Portrait and knew that it was the right move. I was literally surprised at what my hands had created. The best moment was when others felt the same energy; empowered, inspired and the museum reached out to acquire the painting for their permanent collection. It reinforced my mantra to “follow my gut”
I would just add that the Germantown ArtHaus needs your support! We acquired the building in April 2021 and since then have embarked on a fundraising journey to raise the funds necessary to restore a 150+ year old Victorian beauty so we can open and serve the northwest community through the arts. Every bit of support helps. You can find additional information at www.gtownarthaus.com

Kara Khan of Pop-up Polaroid updates us on what she’s been up to here on the blog and on the podcast. She answered our basic Q&A back in 2019. Read that interview here.
It’s really hard to choose a favorite because of the wide array of makers and artists. I really loved the rotoscope exhibit and always love seeing what NextFab is up to.
I made a great connection with someone from the Crefeld School and have had several opportunities to work with the students there as a teaching artist since. It’s been really wonderful!
I loved interacting with kids who attended because their relationship to photography is usually with phone cameras and almost always digital. They always have the best reactions and I’m always happy to get the chance to plant a new seed in someones head about where photography came from and what it can be.
Pop Up is just now getting back on its feet since lockdown and we are just now doing events again so that’s exciting! Covid also disrupted 8×10 Polaroid film production so I have been experimenting with Caffenol printing, which is a process using a coffee based developer that allows me to continue to make large format portraits.
So many things! I have kind of been all over the place, haha. During lockdown, away from my usual creative outlets, I started experimenting with all kinds of mediums. I fell in love with book making and books as an art form, I started writing and illustrating a comic book, have been working a lot with mushrooms, specifically mycelium, as a material to make literally anything, and started learning how to work with Arduino to make interactive art with electronics. I also completed a 4 year-long collaborative project called “Dear Mr. President” that I am really excited about.
