Fabián Rodríguez 🛡💾 🇨🇴 🌴Spotted this cool Canadian-made air purifier: North Box Systems builds quiet, energy-efficient units using PC fans + MERV-13 filters. Think: Corsi-Rosenthal box, but sleeker.

diffractcoloursHere's the 20" <a href="https://tech.lgbt/tags/CorsiRosenthalBox" class="mention hashtag" rel="nofollow noopener" target="_blank">#CorsiRosenthalBox</a> I'm working on. Fans in rectangular housings basically don't exist in the UK, so I made a cardboard shim out of the box for this circular one.This build was a proof of concept (hence the green masking tape rather than duct tape, and the plastic sheeting still on the <a href="https://tech.lgbt/tags/MERV13" class="mention hashtag" rel="nofollow noopener" target="_blank">#MERV13</a> filter boards). I was testing whether the shim and the boards would support the weight of the fan. Despite being a mock up it's surprisingly rigid!Next stage involves building it properly (including sealing those gaps at the corners; the 20" fan is actually more like 21.5" across and the boards are 19.5"), then using my anemometer to measure the flow rate of the finished box, so I can work out what size room it can filter. I'm intending this one for a local community centre where a Queer Club meets, to make their meetings safer.<a href="https://tech.lgbt/tags/CovidIsNotOver" class="mention hashtag" rel="nofollow noopener" target="_blank">#CovidIsNotOver</a> <a href="https://tech.lgbt/tags/CleanAir" class="mention hashtag" rel="nofollow noopener" target="_blank">#CleanAir</a> <a href="https://tech.lgbt/tags/CorsiRosenthal" class="mention hashtag" rel="nofollow noopener" target="_blank">#CorsiRosenthal</a>

Jay BakerI facilitated an online workshop for <a href="https://floss.social/@freetechproject" class="u-url mention" rel="nofollow noopener" target="_blank">@freetechproject</a> tonight and it's the first time we tackled technology to fight <a href="https://todon.eu/tags/Covid" class="mention hashtag" rel="nofollow noopener" target="_blank">#Covid</a> (Co2 monitors, air purifiers, <a href="https://todon.eu/tags/HEPA" class="mention hashtag" rel="nofollow noopener" target="_blank">#HEPA</a>, <a href="https://todon.eu/tags/CorsiRosenthal" class="mention hashtag" rel="nofollow noopener" target="_blank">#CorsiRosenthal</a> boxes, <a href="https://todon.eu/tags/NukitTempest" class="mention hashtag" rel="nofollow noopener" target="_blank">#NukitTempest</a>, etc) as well as why this is important (what Covid is, how it spreads, etc) and the small (predominantly older) group was very open to the ideas, sincerely inquisitive about the topic, interested in reducing risk, aware of inclusion issues, and sensitive to my own experiences as carer for a partner disabled by Covid. I'm also realising that people genuinely refer to "Covid" in the past tense sometimes because they wrongly associate it with government policy, while at the same time they very clearly understand that <a href="https://todon.eu/tags/CovidIsNotOver" class="mention hashtag" rel="nofollow noopener" target="_blank">#CovidIsNotOver</a>. My point is, keep tackling the topic, and keep giving folks the benefit of the doubt -- humans are of course good at heart and state policies, and obviously the establishment media, may very well indeed not, in fact, reflect people's actual concerns about Covid.

jberryNeeded a half break today. Picked up more supplies for blocking and build out. Finished getting any junk around the house into the dump trailer.

Michael Keeling<a href="https://mastodon.social/@nsousanis" class="u-url mention" rel="nofollow noopener" target="_blank">@nsousanis</a> Thank you for compiling these resources. I just built two <a href="https://hachyderm.io/tags/corsirosenthal" class="mention hashtag" rel="nofollow noopener" target="_blank">#corsirosenthal</a> boxes last weekend as sort of prototypes before pitching the idea to my kids' teachers. I followed some guides toward the bottom of the page using PC fans. It was fun and easy, and the boxes seem to be working great.
