Curious about the start-up and functionality of the OpenCPC? Check out our quickstart video! youtu.be/HMPLmfvVzAM

Reducing complexity ➡️ reduced cost ➡️ reduced price. Optical counters are the heart of high-performing CPCs. By using the latest in manufacturing technology and some ingenuity to simplify and modernize our optical counter, resulting in a 10x reduction in associated manufacturing costs.

Hope everyone enjoyed their Halloween weekend! Here at the OpenAeros offices, everyday is spooky season. 👹🎃💆‍♂️

Interested in (a low-ish audio quality phone video of) the talk @masknerd.bsky.social gave this year at the @americanaerosol.bsky.social conference in Buffalo? Well you're in luck! Here's his presentation of low-cost instrumentation measuring UFPs in real-world urban and suburban settings.

Miss our first OpenRespirator Creative Cohort Live meeting? No worries, we've posted our discussion here! Get to know our cohorts, get read-in on their efforts and progress, and see some early designs. youtu.be/C0Q0ZH6e5AA

🦇🎃🧛 'Tis the season... to discuss some of our favorite all-time makes. In the spirit of his OpenRespirator build, Wyatt (one of our ORCC creatives 👻) fills us in on a set of Halloween teeth he absolutely Had To Have and how he taught himself to design and produce his own in middle school.

Join us this afternoon at 3pm CST for our first OpenRespirator Creative Cohort Live Meeting! Get to know our cohorts, get read-in on their efforts and progress, and ask your questions. Tune in here: bit.ly/48jHI6J 😷 💙 ▶️

This year, we’ve been working with a team of passionate, creative makers to put our open source respirator prototype manufacturing methods to the test. We’re so excited to be introducing you to a couple of them this week. In the meantime, here’s some background on what we’ve been up to: (1/4)

Glad to bring the "little CPC that could" to the Healthy Indoor Air event at the UN today. The conversation in clean air are moving in the right directions. Open source hardware will be part of the solutions and proud to show off the OpenCPC as part of tools that can help us measure it.

Aaron (and our little CPC! 🥹) are taking their places on the floor of the UN! This year is the inaugural General Assembly High Level Side Event on Indoor Air Quality and we're so excited to participate. The panel will open soon, watch along here: webtv.un.org/en/asset/k1v... #IndoorAir

Come work with one of our sister projects!

I couldn't think of a better way to have spent the last 2.5 years of my life. I am incredibly proud of what the team at @openaeros.bsky.social was able to accomplish. There were many who said this was impossible, but we did the impossible and this is just the start. 😁 #cleanairisahumanright

We believe that clean air researchers and proponents are doing critical work for our health and future. Too few have had access to the tools to investigate the next frontier of airborne pollutants: ultrafine particles. But we have big news... (1/4)

So, why does clean air really *matter*? The hazards we breathe are largely invisible and - the way we usually read the data - the human cost of those hazards has been invisible too. Aaron makes the case than in 2022, poor air quality was the # 1 killer in America (1/) www.youtube.com/live/b45hakf...

Completely silly this happened you can't cancel science. We will continue to collect some cool data and share it anyways. Plus I feel like you only get a handful times to reference an Indigo Girls song in your title.

In the time since we posted this, entire working groups dedicated to this and related community concerns have been eliminated from the EPA. If you were also slated to present air quality data or programming and would like to join us in presenting online, please reach out!

If you are interested in moving the needle on respirator design, now is your chance.

In the wake of federal changeover, March's EPA air sensor conference has been cancelled. We were excited to present work on community ultrafine exposure to our peers and policy makers. In lieu, we plan to make the presentation to the public online. Abstract is below. You can’t cancel science.

Calling all covid conscious makers, product designers, and 3D artists! OpenAeros is excited to announce our search for makers, designers, and advocates to participate in a first-of-its-kind effort to develop three entirely new, entirely open source respirator designs. (1/4)

At OpenAeros, we strive to meet people where they are with the tools they need. Our mission of accessibility, inclusivity, and decentralized, open source collaboration makes the choice to pivot to using this as our primary social network an easy one. (1/2)

Guess what? That video with the absurdly mixed audio from Christmas Eve? It's updated, audible, and full of extremely timely holiday 2024 tidings. Spend a few minutes relaxing in 2024 nostalgia with us and hear about our open Source approach here at OA. 💙❄️🎅 youtu.be/y4B73273x-8

Happy Holidays from the team at OA! This xmas eve, we're chatting open source ethos, our love for the community, and... christmas pudding? Come for the debrief stay for the blooper reel -- or last week's CPC update ❄️🌲🕯️ youtu.be/kXC-iiBMejU

It’s been a long road  but we are so excited to share  our progress on the world’s first open source, low-cost, condensation particle counter! What is it and why should you care? @masknerd.bsky.social explains why this CPC is a BFD. youtu.be/OxQSAvvOpw4

Excited to share this presentation @masknerd.bsky.social made at #EAC2023, an aerosol nerd gathering, about our latest work on the OpenCPC! www.youtube.com/watch?v=1mmV...

Welcome two new employees to OpenAeros! One is excited to help change the world, and the other is cleaning the air. I will let you pick who is who 😀 Also add another to the #Vflexgang

We love to use technology to solve problems, and leverage the open source model to help other researchers in the future. x.com/masknerd/statu…
