As a professional hardware engineer with little time, I have been working evenings and weekends to create a Bluetooth 4.0 heart rate monitor without a chest strap – all open source hardware and design for such devices should not be proprietary or expensive.
I need help with 8051 firmware modifications of TI’s BT stack (simple changes to send data, sleep). Simple DSP filtering for heart rate sensor data (optical sensor based on pulse oximetry) or need mechanical design help on industrial design of the enclosure. I aim to fit this into the iPod nano 6th generation “watch” form factor so most wristbands can be used.
Would you post this opportunity to work on such a great product on your blog for all to see? I believe all can be accomplished open source with tools such as EagleCAD, FreeCAD, etc. I am very close but could use community help.
