Hi, I need someone who will help me in finalizing a Pulse Oximeter. Person should have end to end experience. He / she will help finalize the components, build a prototype on a bread board. He needs to then help advise relevant fabricator to help fabricate the PCB prototype and then help in the PCB assembly. Person will help in procuring / identifying relevant components / material to procure. He will also inquire and advise with respect to the PCB fab / assy. He will help put together the prototype which will be used for a feasibility research project. Some related links to get an idea of type of produt we are looksing at. http://www.aliexpress.com/item/Christmas-gift-light-and-portable-iHealth-Wireless-LED-Hand-Hold-Pulse-Oximeter-PO3-iPhone-iPad-iPod/1498585348.html http://www.aliexpress.com/item/PC-based-infant-pulse-oximeter-CMS-PN/463734958.html http://www.aliexpress.com/item/New-Wireless-module-NodeMcu-Lua-WIFI-Internet-of-Things-development-board-based-ESP8266/32307066449.html Since...

Engineering of a biometric (fingerprint) module incorporating wifi and bluetooth to develop a smart device for use in the consumer and commercial healthcare markets. The design should take advantage of IOT and be able to communicate via wifi over cloud to application(s) on smartphone or tablet. The communication between the phone app and the product will be bi-directional.

"I have a dream..." I want to build an electronic board for a smart home project. I need digital inputs (for buttons, dry-contact), digital relay outputs (230V, 16A), and some basic logic (like a way to communicate with the board via MODBUS registers for example, and get inputs when button pressed and change register value to make a light ON or OFF). If you know about logic, electronics, PCB design, etc. - I'd happy to hear your insights about making such a board. Also, I still don't have an idea of how can we design that board on your place, and have it working at last - on my place. I'd be glad to hear good ideas for that. (designing it, making it, putting on all components, and seeing it at work..) Thanks.
