Archimedes would call us amateurs but we got within 1% of π using fridge magnets 😁
≈0.798130624867% difference from π
In hindsight, it would’ve helped to have a row of 1/7 pieces since 22/7 is a close approximation for π
Happy #PiDay to all who use MM/DD/YYYY plus anyone who loves knowledge & 🥧!

It was a beautiful rainbow at 5th St Station too! A double one at that.
People have often wondered “what’s at the end of the rainbow?”
…for this observer at that moment where I stood…
The answer was sandwiches.

I’m grateful to be building crowdfunded air filters with fellow volunteers at Clean Air Cville for local teachers & organizations 🙏
We have been building PC fan units predominantly plus some mini #CorsiRosenthalBox #MiniCR units
We are building more this weekend! 😁

Parents in the US- email your kids’ principal(s) this morning to ask that any existing HEPAs or air filters be checked this morning

⚠️ There is a common glitch in vehicle HVAC systems that keeps the fresh air intake door closed unexpectedly
If I forget to press recirc, wait, then press again to turn recirc off (activating motor to open intake), CO₂ builds & meter alarms

Prospective grad students would be wise and fortunate to join your group!
Best wishes on your projects and thank you for all your great #SciComm outreach work @ukhadds.bsky.social! 👏🙏
The aerosol trapping reminds me of the acoustic microfluidic trapping project I worked on in grad school 🙂

Safer Holiday Travel 🧵
Vehicles are often hot spots for airborne transmission since #CovidIsAirborne but simple interventions drastically reduce risk of presymptomatic transmission:
• Turn recirculation mode off
• Use a CO₂ meter
• N95 if in doubt
• Two slightly open windows generate air flow

The arrest warrants are for expressing genocidal intention then overseeing illegal collective punishment, ethnic cleansing, rampant documented war crimes, and genocide.
The crimes are well-documented. I don’t understand your objection.
We agree on other topics incl. environment and epidemiology.

Grotesque to laugh about an easily disproven conspiracy meme such as that.
Millions of people have been killed by SARS-CoV-2 already. Every one had family, friends, careers, and passions.
Lucky you to be in a privileged position to outright deny the deaths and disability SARS-CoV-2 has wrought.

I’ve had some decent results with plasticized window screen over #CorsiRosenthalBox filters for protection and aesthetics
Get a roll of pet resistant window screen from a hardware store or online and stretch it tight across filters, secure w/ upholstery staples, then tape over staples and edges.

We greatly diminish our moral standing to denounce negligence on SARS-CoV-2 and H5N1, as well as the climate crisis, if we fail to denounce ongoing genocide

Harder to say no if you made one especially decorated to be kid friendly and put a sticker “a gift from local students to BC Children’s Hospital”
Add a bin with some balloons as a fun waiting room activity

Interesting idea!
Coincidentally, I was experimenting with a hinged two filter wedge design last week (3rd one pictured).
The idea was to have a flat-packing kit to save cargo space on a car trip yet still quick to assemble upon arrival.
Thanks! I’ll try it 🙂

The big ones are still the best on performance!
Lots of CADR
If noise is an issue, you can trade some performance for quieter operation & still probably beat HEPA on $ per CADR
I’ve used this one on a MiniCR
Still need to re-measure de facto CADR, but it does keep the unit on b/c more tolerable

Not included of course are the costs and logistics for warehousing, labor, unit tracking and distribution.
But hopefully enough info to help those interested in making them.

Hi Everyone! 👋😊
That’s me on the left in the first picture. I’m a father, husband, and PhD analytical chemist passionate about adoption of clean air practices and tools to help people thrive.
If anyone would like help building DIY PC fan air filters & getting them placed I’d be happy share info!

I explicitly said that upon seeing evidence of such crime I would condemn it.
Will have to review the 5 articles linked in the thread soon, so comments pending on those.

Two Arctic P14 fans (www.amazon.com/dp/B07HCKWF2X), stacked together inside the box with foam core spacers in corners, mounted on the under side of a foam core board panel.
They are really quiet. One fan struggles to pull enough air through the mini CR filters, but two together create more flow.

One point to add-
It’s hard to beat the AC powered fans in terms of availability & cost, so they are great for rapid deployment of air filtration.
The mini CR was built w/ HT-904 fan from Target. If you prop it up 5”, no need to disassemble.
Top plate (12 5/8” square, 4 7/8” radius hole) fits over
