Enabling F-bus communications with Arduino

It’s always nice to see how creative makers approach communication issues in DIY projects, and today we would like to highlight the approach followed by Alex, from InsideGadgets.

On his website, he provides a detailed tutorial on how to use an old Nokia 6110 (or any derivatives) to send SMS messages by exploiting the Nokia’s F-bus, a simple bi-directional and full-duplex serial protocol.

After considerable reverse engineering work, made possible by useful online documentation, Alex finally managed to send a SMS from his Arduino board, connected to the phone, thanks to AVR libraries made available by AVRFreaks.

Portable and cloud-based heart rate tracker

In his blog, Charalampos describes his experience with SeeedStudio’s Grove Ear-clip Heart Rate sensor and Cosm (former Pachube) cloud service. The employed sensor is quite cheap and can detect heart pulses from the ear lobe, by measuring the infra-red light reflected by the tissue and by checking for intensity variations.

By connecting this sensor with an ADK board and, in turn, with an Android smartphone, Charalampos implemented a portable heart-rate tracker, which is used to send the recorded data to Cosm cloud service.
