Data from: Contrasting patterns of functional diversity in coffee root fungal communities associated with organic and conventionally-managed fields
<p>The structure and function of fungal communities in the coffee rhizosphere is shaped by crop environment. Because coffee can be grown along a management continuum from conventional application of pesticides and fertilizers in full sun to organic management in a shaded understory, we used coffee fields to hold host constant while comparing rhizosphere fungal communities in markedly different environmental conditions with regard to shade and inputs. We characterized the shade and soil environment in 25 fields under conventional, organic or transitional management in two regions of Costa Rica. We amplified the ITS2 region of fungal DNA from coffee roots in these fields and characterized the rhizosphere fungal community via high-throughput sequencing. Sequences were assigned to guilds to determine differences in functional diversity and trophic structure among coffee field environments. Organic fields had more shade, a greater richness of shade tree species, more leaf litter, and were less acidic, with lower soil nitrate availability and higher soil copper, calcium, and magnesium than conventionally-managed fields, although differences between organic and conventionally-managed fields in shade, calcium and magnesium depended on region. Differences in richness and community composition of rhizosphere fungi between organic and conventionally-managed fields were also correlated with shade, soil acidity, nitrate, and copper. Trophic structure differed with coffee field management. Saprotrophs, plant pathogens, and mycoparasites were more diverse and plant pathogens were more abundant in organic than in conventionally-managed fields, while saprotroph-plant pathogens were more abundant in conventionally-managed fields. These differences reflected environmental differences and depended on region.</p> <p><b>IMPORTANCE</b></p> <p>Rhizosphere fungi play key roles in ecosystems, as nutrient cyclers, pathogens, and mutualists, yet little is currently known about which environmental factors and how agricultural management shape rhizosphere fungal communities and their functional diversity. This field study of the coffee agroecosystem suggests that organic management not only fosters a greater overall diversity of fungi, but also maintains a greater richness of saprotrophic, plant pathogenic and mycoparasitic fungi that has implications for efficiency of nutrient cycling and regulation of plant pathogen populations in agricultural systems. As well as influencing community composition and richness of rhizosphere fungi, shade management and use of fungicides and synthetic fertilizers altered the trophic structure of the coffee agroecosystem.</p>

Coffee can amplifier
Coffee can amplifiers did exist. It's a combination broadband linear amplifier and one or more taps built into a modified coffee can. Each amplifier was assembled by hand, with components soldered directly to the can. Steve Allen donated the amplifier that is on display here at the Cable Center in Denver. The amp he donated was 100% discrete connectors with transistor cans and all the usual stuff. These amplifiers were supposedly built by a small operator in Kyburz, California using schematics from some existing equipment. The basic components were a 5-lb coffee can. Folgers seems to be his preferred brand. The tinned interior of the can facilitated soldering. The builder made components such as fuse clips and power directing jumpers out of pieces of the same can. The amplifier was "tuned" by crimping the edges of the amplifier portion, and then placing it back into the remaining portion of the can until it stopped oscillating.

Old Rusty Coffee Can
My first attempt at 3D-scanning, the walls were too thin and so there is a lot of holes in it, although it was whole in the real world. Photos taken with Iphone, combined in meshroom, then a lot of cleaning up in Blender and Substance painter. Source: Objaverse 1.0 / Sketchfab
