Where are you located? That could affect the availability of various hardware/costs of shipping/etc.
Firstly I want to make a keypad that will record it's own pressed keys with a time stamp.
Where is this data being record to? SD Card? EEPROM to be retrieved later?
It would need to be portable so it'd have to have it's own power source
How long would it need to be operating without power? Aside from recording the time when a key is pressed, is there anything else it would need to do that might put a drain on its battery?
And if anyone can put this initial stuff together for me and write the code and give me a working prototype to play around with for a while, I would gladly pay.
Are you looking for someone to essentially build/code/case the project and ship it to you, or hook everything up, write the code and send you the plans?
