Updating the RPI NAS

The RPI NAS that I had built a nice white wood box for has a new home. After finding a design for rack mounted raspberry pi, I knew I must have it. I came across the following design which holds 2 pi's:

I already have one running openhab and then having a second running openmediavault and pihole, this was perfect. I also have a 3d-printer, so no prob! Well it took a few months for parts to come in and my 3d printer kept breaking. But its finished! Since this picture was taken I have put the 2nd raspberry pi in the setup, everything seems to be running smooth.

If you are curious about the code running the OLED displays. Follow this adafruit blog post, I have raspbian OS launch a python script as a service on boot.

Brew Computer Software Update

A while back I had re-written the homebrew computer python code. It was around the time I was working on the water level sensor for the brew setup. While updating the python code I had added a few new features:

• Added support for 2nd serial/usb connection. One for the arduino handling the buttons and switched under the monitor, the other for the new water level sensor.
• Added Blynk support so I can remotely monitor the brew process using the Blynk app.
• Added PID algorithm to better maintain wort temperature
• Updated the GUI, depicted below

I have now brewed twice with this new setup, so fine tuning is still left to do, but it feel way better to brew with. I have also now made the code available at: https://github.com/kbittle/BrewComputer
