Kegerator: Integration with DynamoDB

This afternoon I wrote the code that listens to the serial output from the Arduino and puts the necessary data into DynamoDB.  I’ve successfully tested it with the flow sensors and it works!  This is a bit exciting, as it’s the first time I’ve managed to have a direct connection between a physical device and […]

Arduino code: RFID reader and valve control

I’ve written the Arduino code that reads an RFID tag and triggers solenoid valves that will be in the beer lines.  I’ve prototyped the circuits and they all work, but I don’t have them all nicely diagrammed and cleanly constructed.  Once I redraw them for a single board I’ll post more details. The most recent […]

Adding the beer labels to the UI

Sorry for the lack of frequent updates recently.  Work got a bit crazy last week and I’m on-call this week so I haven’t had as much time for coding on the side. This evening, though, I was able to add basic support for displaying beer labels in the UI.  You can view that commit here.

Kegerator coding started

I’ve started on the coding for the internet-enabled kegerator.  It’s just basic UI stuff, as I’ve never really done a UI before apart from a tiny bit of web stuff.  It’s up on github here.  The next step will be hooking up an arduino and the flow sensor so that I can test that this […]

Turret V2: Automated artillery

I made a small turret last year when I was living in an apartment.  I now have a house, so I’m thinking a bit bigger.  If I can find a place to test some model rockets, I’m going to try building a turret that holds a battery of model rockets.  It’ll have a Raspberry Pi […]

Internet-enabled kegerator

In addition to making gadgets, I also brew and drink beer.  In order to help with this, I have a kegerator.  However, it isn’t all that fancy.  It doesn’t have any flashing lights or buttons, just two tap handles.  In order to make it a bit more interesting, I’m going to add an LCD screen […]
