Dog Water Bowl Scale, Part 3: Final assembly and installation

In my previous post, I covered the mechanical construction of the scale. In this post, I finish assembling the scale, calibrating it, and installing it.

After painting I put feet on the scale so it won’t soak in water spilled on the floor.

Dog Weight Scale part 15: scale is installed and uploading real data

In my previous post, I wrote the Raspberry Pi Node.js code to upload data from Pippa’s dog bed scale to data.sparkfun.com. This post covers how to make a Node.js program run automatically when the Pi is turned on. Oh, and at the end I installed the finished scale under Pippa’s bed.

Dog Weight Scale part 14: uploading data to data.sparkfun.com

In my previous post I finished the hardware for the scale and calibrated it. This post covers getting data from the scale to Sparkfun’s Data Warehouse.

By the way, the nRF Master Control Panel (BLE) from Nordic is the perfect tool for debugging Bluetooth Low Energy devices and messages.  It understands a pile of standard Bluetooth data types,as well as the Physical Web, so it’s a quick way to find out whether your Arduino project is sending the right data.
