Big announcement! 📣 LaminAir is open-source under GPL-3. Have access to a 3D printer? You can print the pieces yourself -- save money on shipping, labor, etc. 🧵(1)
Walkthrough of me putting the pieces together. Takes about 1 hour 45 minutes to assemble: (4)
If you already have a USB battery pack and not use the battery-switch enclosure, you could get all the parts for about $130 USD. Happy Building! (5).
However, if you'd rather purchase a fully assembled kit and you live in the U.S. or Canada, pre-orders are available here, with production and shipping around Feb/March : (END).breathesafe-llc.myshopify.com/products/lamin…
Introducing the LaminAir. *Safer indoor dining. Safer working in the office.* At least double-digit exposure reduction factors, while breathing 12 inches away from the device 🤯 🧵 (1)
First, what is exposure reduction factor (ERF)? It's a measure of how clean the air when using a device vs. not. If you get an exposure reduction factor of 20, that means the air is 20 times cleaner while using the device vs. not. (2)
N95s filter at least 95% of particles and offer great protection against many respiratory pathogens, smoke, airborne allergens, etc. (3)
I am pleased to announce that I have an update to the design! AirGo: Clean Air on the Go! 🧵 @FitTestMyPlanet @ghhughes @masknerd @sameo416 @Stoffel78179983 @sri_srikrishna @AbundantLandUse @kprather88 @CorsIAQ @JimRosenthal4 @syntagmatic
Wearing N95 and/or elastomeric masks is one of the best among the many ways to protect oneself. However, there are some cases where this is challenging to do: at the dentist, or at indoor dining venues.
Did a few flights recently. Last flight 5 out of 50 ppl were constantly coughing, unmasked. At another @UnitedAirlines_ flight, CO2 readings stayed consistently high (1300 ppm - 1500 ppm). Thanks for making me feel safe, @flo_mask. A review of the Flo Mask Pro 🧵 1/x
Breathability: 10/10. So far, I've used the Pro filter which is supposed to be harder to breathe through than the Everyday filter, but had no issues at all with it. I'm looking forward to trying out the Everyday filter! 2/x
Stylishness: 10/10. I think it looks "less intense" than the GVS Elipse. 3/x
Someone asked on reddit (bit.ly/2S5tOPA) about the "amicable disagreements" between @yudapearl & @_MiguelHernan are, and what the do-operator is. Here's my summary: (1)
The do-operator represents an idealized intervention. In cases where the "treatment" is something that is well-defined (i.e. the exposure in a randomized control trial, such as taking aspirin), the two camps are in agreement. However, in cases where the "treatment" is ... (2)
non-manipulable by itself in the real-world (i.e. obesity), the two camps diverge. Hernan's camp believes that 1. the value of E(Mortality | do(Obesity = 1)) has no real bearing to the real world, hence "extrascientific" and "magical." (3)
