After my initial PCB success with Maker Studio, I uploaded the design files to three more board houses. I had planned to try four or five more, but I started to get the impression that many of the China-based sources used the same fab house, so I stopped at three.

Elecrow’s basic board fab service supplies 5 or 10 PCBs for $11.90, with a basic international shipping cost of around $7 for 5 boards. Although I haven’t been paying close attention to delivery time for these reviews (too many variables), I will say that Elecrow was significantly slower than the other three sources.

EasyPulseV1.1Board2

Easy Pulse is a DIY pulse sensor that uses Photoplethysmography principle over a finger tip to detect the cardio-vascular wave or PPG signal. The sensor outputs a clean analog PPG signal as well as a digital pulse signal that is synchronous to the heart beat. The sensor can be interefaced to Arduino or any other microcontroller platform to make a DIY pulse meter or heart rate monitor. The sensor is designed by Embedded Lab and is now available from Elecrow for only $18.50.
