Whether you are vegan or just want to try something new in the shoe department, Adidas will soon have your feet covered. They are currently working on a leather alternative made of mycelium, which is the network of fungal filament material that produces mushrooms, toadstools, truffles, and more. Hopefully they’re not using live mycelium, otherwise your shoes will grow mushrooms when they get wet like this mycelium canoe we saw a few weeks ago.
Adidas have really rooted themselves in sustainability over the past few years. They claim to have made 15 million pairs of shoes in 2020 out of recycled plastic waste collected from beaches and coastlines, and they’re shooting for 17 million pairs in 2021. The company started offering these in 2017, and they feature thread in the laces and other places that was spun from ocean plastic waste. Adidas are also using a lot of recycled polyester and are developing a new type of recycled cotton, according to Business Insider.
No use for mushroom shoes, canoes, or coffins (translated)? Everyone could probably use more insulation in their home. Why not grow your own?
Thanks to [Charles] for the mycelium coffin tip.
Mushrooms might be the most contested pizza topping after pineapple, but can you build a boat from pineapples? Probably not, but you can from mushrooms. Mushrooms, or rather their mycelium root systems, can be used for things like packaging, insulation, and furniture, and it could be the next thing in floatation, too. Just ask [Katy Ayers], a Nebraska college student who built an eight-foot canoe molded almost entirely of mycelium.
[Katy] got into mushrooms when she was tasked with researching solutions to climate change. She loves to fish and has always wanted a boat, so when she found out that mycelium are naturally buoyant and waterproof, she decided to try using it as a building material.
[Katy] floated the idea by the owner of a local mushroom company and they got to work, building a frame suspended in the air by a hammock-like structure. Then they covered the boat’s skeleton with spores and let it proliferate in a hot, humid growing room. Two weeks later, they had a boat made of live mycelium, which means that every time it goes out on the water, it spawns mushrooms. The total cost including tools was around $500. The boat experiment spawned even more mycelium projects. [Katy] has since experimented with making lawn chairs and landscaping bricks from mycelium.
Don’t want to wait to grow your own mycelium boat? You can build one out of stretch wrap, packing tape, and tree branches.
Thanks for the tip, [ykr300]!

Take a guess. What is the featured picture for this article? If you’re channeling your inner Google image recognition, you might say: “Best guess for this image: rock.” But, like Google, you’d be wrong. Instead, what you see are bricks made out of fungi obtained from tissues of mycelia.
By taking fungi obtained from tissues of mycelia and storing them in a jar filled with a growth medium (usually sawdust), MycoWorks is creating all sorts of materials with exciting properties. In just three to seven days, the fungi and sawdust mixture expands and forms into clumps of material, which are then used to create products like handbags, purses, bricks, you name it. According to co-founder Phil Ross, “production of this material is similar to making ravioli from scratch, and the final product is more resilient than concrete.”
The resulting materials are buoyant, self-extinguishing and stress dissipating. Moreover, the bricks are alive up until they are put in a kiln. This means bricks that are placed next to each other will grow together, effectively enabling a structure to be made out of just brick, no mortar. And, while they’re not 3D printed, houses made in this fashion have great potential. If these cool new materials have got you excited, and you want to get cozy with the fungus among us, why not go all out with an automated mushroom cultivator?

Lots of people have developed their own systems for automating the growth of plants. Keeping the environment under tight control leads to better yield, and computers are better than humans at remembering to water the plants regularly. [Kyle] is into growing mushrooms (the legal, edible type) and automating things. This led to his system for automated mushroom cultivation.
We’ve seen an automated system for growing fungi before, but [Kyle]’s project is a bit bigger. He’s built a sealed room for growing mushrooms. The room is sealed with a plastic sheet, using magnetic strips to create a doorway. Within the room, a heater, humidifier, and circulation fan control the environment. Temperature, humidity, and dew point in the chamber are constantly monitored and adjusted as necessary.
The entire system is controlled with a Raspberry Pi and custom software, which is available on Github. GNUPlot is used to generate graphs, which are accessible through a web server. The web interface also allows the parameters of the chamber to be tweaked remotely. Based on the settings, the Raspberry Pi controls a set of relays to keep the chamber in an ideal state.
This might be an old trick, but it’s still cool to see a functional tool like the oscilloscope manipulated for an unrelated purpose such as this. [Jerobeam Fenderson] made a video explaining how to input stereo audio into an old digital scope in order to create of all things, dancing mushrooms… because why not?
In this case, [Jerobeam] used a Tektronix D11 5103N set in X Y mode and attached the left and right channels from his RME Fireface UC audio interface. One channel corresponds with X, and the other with Y. From here, he controls the wave forms discretely with the help of software like Pure Data (Pd) and Max (not free, but more powerful) which are visual programming environments made to enable musicians and artists to create software without writing lines of code. His video explains how to make a circle out of a sine wave, and then beat the crap out of it with math far beyond our comprehension. The outcome is pretty mesmerizing and leaves us wanting to try it out ourselves. Luckily, if you’re interested in experimenting with the voice of sine waves… [Jerobeam] has more information on his blog on how to do some scope play of your own whether your hardware is analog or digital.
