As part of my shift towards ESP32 I decided to create my own PCB's for Gravitymon so that there is an option that supports all the features and also me to add more features as we go. I also wanted to have PCB options that support both the PILL case as well as the standard PET used by the original iSpindel......
I have now shifted my focus to ESP32 based boards for my projects and update Gravitymon to support some new options. The challenge is that most existing PCB's still focus on the ESP8266 so I have started to collaborate with a few PCB designers.....
The inital kegmon hardware setup was based on the older ESP8266 and was updated to ESP32s2/s3 later on. Some of the requests for updates would not work with the current hardware limitations, both RAM, GPIO pins and CPU so I needed to look for new options.....
Gravitymon has got support for a new modern gyro and the new setup also opens up for more options in the future. The new gyro is still experimental but the fermentation I have tested has shown very stable and reliable results....
I was using the brewpi@8266 for quite some time which has served me well. I tried to integrate and use this from my brewlogger setup at first but it but the integration was not straightforward. So I decided to give this a try and create my own controller...
I saw the need for having somewhere to record, store and experiment with the data sent by the devices. I was using influxdb2 for a long time but that did not give the possibiliities to analyse the data in an easy way or test the push features...
I have been working on a pressure monitor for a few years with the focus on digital I2C sensors for good accuracy. The challenge has always been the connection between the sensor and the keg/fermentation vessel and also a service to collect and use the data...
I have other projects that is not beer related that I need a way to flash...
Building an iSpindel using the more modern ESP32 is quite easy, there are a few ESP32 mini boards that works as a drop-in replacement for the ESP8266...
Who would say no to better accuracy and lower power consumption. I'm really happy that Levi--G took the time to build it and add this feature to the project...
