My current project:
The t-couples are from thermoworks.com, and I am using the MAX31885 breakout board from Adafruit to read the t-couples. The project is sitting on a 8800mAh battery that will power it for days. Currently, I am sending two data streams to xively.com, which allows me to plot both sensors data over time. I love to BBQ, so I use one sensor to read the grill temperature and one to read the meat temperature. It is perfect for long cook times like a brisket. xively.com has great libraries for lots of languages, and I modified an example app for the iPhone to read the datastreams from both sensors.
Currently, I am using both SPI busses on the imp for each chip. Can I just use one bus and trigger the chips with different chip select pins?
Next steps in the project.
- Get it all in a case with a smaller battery and charging circuit.
- Install an LCD for local read-out. TFT?
- Add Core-Plot to the iOS app to plot data.
- Add bluetooth integration for times when WiFi is not available.
I’d love to get ideas and feedback on this.
