The folks at SenseBridge, a research group that meets at the NoiseBridge hackerspace, just released this Heart Spark necklace pendant. It’s got a receiver for a Polar heart rate monitor built into it, and has space to add a real-time clock and extra storage if you want to turn it into a heart-rate monitor. The source code for the project is already available, and schematics and board layouts are promised soon.
This looks like it would be fun both as-it, and as a building block for more advanced body monitoring designs. Anyone want to make a recreation of Takehito Etani’s Pimp My Heart?
