SF Bicycle Coalition is suggesting that it's fine: https://twitter.com/sfbike/status/1239658920718643200

I’m sure they’re experts in this area and definitely an authority on the matter. SF has a massive homeless problem, how “happy” do you think that virus is in the city atm?

If you implement "middle out" grasshopper rubbing, you can triple production

This sounds great, can't wait to check it out. After taking a Permaculture Design Course, I fell in love with the ideal of living a better, more "luxurious" life that has not only a lower impact on the planet, but a positive impact. I'm on my way down that path, but still figuring out how to make it replicable.

Do you have a source for any good bone conduction headphones? I have a damaged eardrum that stops me hearing low frequencies.

Recently tried a demonstration at SF's Exploratorium which involved biting a metal bar, and the result was incredible!

Most bone conduction headphones I find when searching (eg AfterShokz) appear to rest against the bones around the ear, so I'm not sure if they're as effective.

FWIW - it was actually a pair of AfterShokz that my dad tried (as well as a different brand of wireless ones).

Thanks, I'll see if I can try some in person

Thanks for sharing this, it's great to see your process.

I'm working on something vaguely related, a grid-based synth-controller/sequencer with a bunch of i2c shift registers and laser cut hardware. I've been thinking about building a pressure-sensitive hex-layout keyboard next, you've given me a bunch of ideas and inspiration.

Thanks. Pressure sensing is actually pretty simple and cheap, unless you have a really large number of inputs (like I have). I was planning to switch to a matrix layout in the next version to reduce the number of ADC chips I need, but then I'll have to figure out how to mitigate ghosting.

I haven't used any of Sensitronic's producs, but they do have a lot of good information on their site about the various ways to use force-sensitive resistors.

Without giving away too many spoilers, you might enjoy "The Expanse" books/series

Exposed earth typically emits carbon dioxide. It's not "emit" in the way a breathing mammal would, more that the carbon in the organic material is oxidized at a greater rate because it's exposed to the atmosphere.

Before deforestation, carbon would be pulled from the atmosphere by trees, turned into plant material, fall to the ground as dead leaves or whole dead trunks and be sequestered into the soil as they broke down and were buried.

Also c90adventures - a very low budget but hilarious series of long distance rides.

Samsara - https://en.wikipedia.org/wiki/Samsara_(2011_film) A non-narrative film, with stunning visuals. I feel it shows some of the best and worst of humanity, but in a non-pushy or judgemental way. It just leaves you to make your own conclusions.

I watched Samsara while on LSD it was a very beautiful experience. Some of the scenes really hurt me deeply. I couldn't help but cry.

Also check out Ron Fricke's Baraka (https://en.wikipedia.org/wiki/Baraka_(film)). It's just as beautiful in my opinion.

The entire Qatsi trilogy

Was about to suggest that as well. Its a superb film.

I was thinking more the first Iron Man movie
