Hello, Bulding a scale from scratch is very hard. You need to make the 3D mechanical desing and put the electronics in it and test it. This can take a lot of time and will cost you a lot of money. I have for you a simple solution. Take an existing scale and just add the electronics that send the Bluetootht message. This can fit in you current project budget. I also can help you with bouth of this version. About me: I have 8 years of product design in the automotive industry. I am an expert in: - Dc - Dc converters - DDRAM memory's simulation and layout - USB charging - accelerometers , gyroscopes - GPS and GSM - LCD Displays - LED power calculation As a Layouter I have 5 Years experience. I am an expert in : - Power Dissipation Calculation - EMC Rules - Impedance Calculation - Manufacturing Rules I have made Layout for ARM processor. Work also with BGA footprint. I have done projects even on 10 layer. So I know how to build a layer stack up. As Layout and Schematic software I am an expert in Eagle, PADs, Zuken. As Simulation software for the Schematic I used LTSpice. Thank you for your time, Have a NIce Day, Alex.

Hello, thank you for the opportunity to bid on your project! I've designed numerous Bluetooth and BLE systems using Nordic's nRF51822 series of system-on-chip radios. I feel that this project could easily be designed with two of these radios. My bid would give you a system level diagram of both the scale and display, overview of the software logic or "flow" on both modules along with a preliminary (major components) Bill of Materials to develop a prototype scale and display. I'll also include a quote for the design and manufacture of a prototype unit based on the deliverable for this project. I'm looking forward to working with you. Regards, Andrew
