Cyborg Mushrooms

November 15, 2018 by 3 Comments

Of all the fictional cyborgs who turn against humanity to conquer the planet, this is as far from that possibility as you can get. These harmless mushrooms seem more interested in showing off their excellent fashion sense with a daring juxtaposition of hard grid lines with playful spirals. But the purpose of this bacteria-fungus-technology hybrid is to generate electricity. The mushrooms are there to play nurse to a layer of cyanobacteria, the green gel in the photo, while the straight black lines harvest electricity.

Cyanobacteria do not live very long under these kinds of conditions, so long-term use is out of the question, but by giving the cyanobacteria somewhere it can thrive, the usefulness grows. The interplay between bacterial and supportive organics could lead to advances in sensors and hydrogels as well. At some point, we may grow some of our hardware and a green thumb will be as useful as a degree in computer science.

Hydrogels could be the next medical revolution, and we’ve already made hydrogels into tattoos, used them as forms for artificial muscles, and hydrogels can be a part of soft tissue printing.

Mycelia + Sawdust = House?

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?

Cultivating The Fungus Amongus

April 11, 2015 by 16 Comments

A while ago, [Kyle] built an automated mushroom cultivator. This build featured a sealed room to keep contaminants out and enough air filtering and environmental controls to produce a larger yield of legal, edible mushrooms than would otherwise normally be possible.

Now, he’s at it again. He’s expanded the hardware of his build with a proper, grounded electrical box for his rig, added more relays, implemented PID for his temperature and humidity controller, and greatly expanded the web interface for his fungiculture setup.

Like the previous versions of his setup, this grow chamber is controlled by a Raspberry Pi with a camera and WiFi module. Instead of the old plastic enclosure, [Kyle] is stepping things up with a proper electrical enclosure, more relays, more humidity and temperature sensors, and a vastly improved software stack. Inside the enclosure are eight relays for heaters and humidifiers. The DHT22 sensors around the enclosure are read by the Pi, and with a proper PID control scheme, controlling both the temperature and humidity is simply a matter of setting a number and letting the machine do all the work.

The fungi of [Kyle]’s labor include some beautiful pink and white oyster mushrooms, although with a setup like this there’s not much fungiculture he can’t do.

Mushroom Terrarium Automation

Like many specialty plants, growing mushrooms requires that you keep a fine balance between humidity and temperature. this can be fairly tedious at times, so many opt for automated systems. [Anthony_p1234] has chosen to build his own.  Using an Arduino, he controls power to two heating pads, a sonic humidifier, and an air pump to keep his mushrooms happy. He shares the process of building the system, testing and calibrating the parts and putting it all in use. We didn’t see any schematics, but he does describe everything fairly well. The source code is available for download.
