I'm building a unit with two buttons on it.
For this bid I need an internal circuit boardlogic designed. The unit have two buttons and a few leds (optional) and a GSM transmitter.
The number of times each button was pushed is being counted and accumulated and once an hour all this information is being sent to a centralized server in the internet (the API for the server is ready). The leds will indicate the box status - errors, battery running out, etc.
The size of the box should be about 100mm X 100mm X 20mm and the batteries should last a couple of months at least (optional - solar panel can charge batteries during standby).
Unit spec is attached.
The project must include:
2. Circuit Operation description
4. Circle prototype - built and tested
5. All technical data for production
In addition to the above I'm looking for standard casing (due to lower cost), please feel free to sagest casing as described here and seen in a "sample" PDF.
The project must include working HW prototype as well.
