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 […]
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 […]
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.
I’ve managed to get an Arduino to transmit data from two liquid flow meters to a computer (currently my Mac, but it should also work with a Raspberry Pi). This causes the basic kegerator UI to display the amount consumed from each keg. The next step will be establishing the data persistence story – at […]
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 […]
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 […]
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 […]
