If you have landed on this site because you are looking for the tutorial on the sourdough incubator, this is the wrong post. Click here to go to: How to build an Arduino based sourdough incubator. This is a new series of posts. I want to try to document some of the ideas I have, which I probably never get around to build (time constrains, lack of intelligence, lack of education, or all of them).
This month: The next fully web enabled sourdough incubator or as I call it – Sourdough incubator v2
Here is my idea on post-it’s first as I usually document my stuff.
The basic idea is to make the incubator fully accessible via wlan (internet?). Also I would like to move the program logic to my home server (a Raspberry Pi) and have only the absolute minimum of electronics connected to the incubator:
- 1 ESP8266
- 2 relays (one turns the heating on and off, the other the fan for cooling)
- 1 simple temperature sensor
No screen/user interface connected to the incubator itself. I like to select the program (1 of 4) via webpage, also I like a stop/off button to stop the selected program and a free mode, where I can select a specific temperature and time frame. This is probably all running on the Raspberry Pi.
I always want to know the current temperature within the incubator. Also a notification (email, message), when the program has finished or another phase begins and I have to act.
Nevertheless, there are some open questions:
- Is it even possible to run 3 components with an ESP8266? I only found tutorials for one component so far.
- How do I power the incubator with only one plug? The light bulb for heating runs with 220v, the fan with 5v, and the ESP8266 with 3.3 (if I remember correctly).
- What kind of software, application, scripts do I need on the Raspberry Pi?
After some time thinking about the idea and defining the open questions, I realized that this is beyond me. There is too little knowledge on coding. Also the power supply seems way to tricky – and I do not want to burn down the house.
Good idea …but…
