The whole Mushrooms' Paradise blog   Components ESP32 DIY Irrigation kit Soil moisture sensors. Water pumps 3.3v Relays And the problem   This post is about the vegetable part of the farm. This part doesn’t use anything from Element14 kit, but I thought it could be a nice add-on to mushrooms farm.     Components    ESP32  Vegetable part of the farm will be controlled by ESP32. I chose ESP32 because I will need analog pins for ...
The whole blog   Introduction Step 1. Rehydrating the mushroom cakes Step 2. Preparation of Vermiculite and Perlite Step 3. Putting mushrooms on the trays   Introduction  To grow mushrooms I used the “PF Tek” method. Full description on how to do it can be found here: Start To Finish “PF Tek” For Growing Mushrooms At Home (Part 1) Start To Finish "PF Tek" For Growing Mushrooms At Home (Part 2)   I already did the initial part of it ...
The whole blog   For the enclosure I used an old non-working fridge. Mushrooms and vegetables will grow inside the fridge, electronics are located just next to it. The reason for electronics to be outside is I need RPI to be able to connect to WiFi and it will be not possible from inside of metal fridge. The access side of the enclosure is covered with plastic film, to make humidification more efficient.   Here are the dimensions.   Fridge seems to be pretty big, so I thought it ...
The whole Mushrooms' Paradise blog   3v Relays IoT Relay Other The final result Demo run Data visualization by ThingSpeak Components (continued from Mushrooms' Paradise #9. PI components review in detail. Part 1 ) 3v RelaysThere were not a lot of 3v relays options. I got mine here and they don’t have any specifications listed. But it looks like they need less than 16mA, otherwise they will not work.     IoT RelayIt is used to run a humidifie ...

The whole Mushrooms' Paradise blog   Power supply Raspberry PI Enviro HAT Humidifier components. Fan components. LED strips.   Power supply  The power supply is an ATX PSU with 24-pin cable.  The power connector pinout Detailed description can be found here: ATX Power Supply Pinout and Connectors. Basically all back wires are Ground, yellow - 12V, Orange - 3.3V, Red - 5V. Note: green wire - PS_ON needs to be connected to the Ground for  the p ...
The whole blog   The Wiring Pi package GPIO Utility Allow connection to PI desktop GUI without monitor   The Wiring Pi package  The Wiring PI package contains the GPIO utility which I can use from  the Terminal to debug wiring issues. The Wiring Pi package was not installed with my PI by default, so I needed to install it manually. Instructions to do so can be found here: wiringPi updated to 2.52 for the Raspberry Pi 4B. Basically the commands to be run from T ...
The whole blog   I will have roughly half of the components controlled by the RPI and half by the ESP32. RPI components are controlling mushrooms part of the farm, ESP32 - vegetable part. This entry is about the components controlled by the Raspberry PI.   This is the set before being assembled. It contains: 1 Raspberry PI 4 heat sinks for RPI 1 Enviro HAT 3 computer fans 3 LED strips 1 Humidifier 1 IOT Relay for humidifier 2 5V relays for LEDs and for fans 1 ATX PSU (power supply un ...

The whole blog   For vegetables part of the garden I chose lettuce and radishes, I explained the choice in Part #1 ( Mushrooms' Paradise #1 - Initial Plan | element14 | 1 Meter of Pi) of the blog.   The vegetable part of the garden will be at the bottom of the enclosure, in planters.   For Lettuce, after some research (for example, growing facts How to grow lettuce indoors? An easy step-by-step guide – Bulbo® and growing instructions Growing Lettuce Indoors Year-Round ...
The whole blog   I plan to use Raspberry PI and ESP 32 as controlling devices - the brains of the project; Enviro for temperature and humidity sensors, humidifier, 4 soil moisture sensors for vegetables part of enclosure, 4 fans for ventilation, 4 water pumps for irrigation, several LED strips as growing light. RPI will control Enviro, fans and humidifier. ESP 32 will control the soil moisture sensors and pumps. ESP 32 will communicate with the PI using MQTT. Optionally (if I will be abl ...
The whole Mushrooms' Paradise blog   Introduction Step 1. Create a still air box Step 2. Inject jars with mycelium Step 3. Move jars to a dark clean chamber and wait   Introduction  This is the last part of creating mushroom cakes. The goal today was to inoculate them with mycelium and let it grow in a dark place.   During this step the medium is sterilized already. However if the environment where this task is done is not sterile, there is a high probabili ...
The whole Mushrooms' Paradise blog   Introduction Step 1. Modification of the jars Step 2. Preparation of the medium mix Step 3. Filling jars with the medium Step 4. Jars' sterilization process   Introduction  This post is not about electronics but about preparation of mushroom farming. It will take about 2 weeks for mycelium to grow, in any dark place, no specific temperature or humidity. During this time I can set up the electronic part of my enclosure. ...
The whole blog     Abstract Setup Environment Enclosure Light Irrigation Power source Air circulation Camera Abstract  My project will be to grow as many mushrooms as possible in a contained space. I also want to experiment and see if I can grow lettuce and radishes in the same environment.         Choice of crops   All the crops are chosen to maximize the amount of protein, fiber, vitamins and micro elements.   M ...
