White Oyster Mushroom

Automated Mushroom Cultivation

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.

Tripping On Oscilloshrooms With An Analog Scope

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.

You can see the dancing mushrooms in his video below:
