Alphabet audio player


I'm looking for someone to design and build an alphabet playback device. Size would be about that of an A4 page, not too thick - doesn't need to be hi-tech as it's going to the Solomon Islands as an aide to teach English.

It needs to be lightweight and have low power consumption - maybe even a solar strip from a calculator could be used perhaps so we don't need batteries?

I would prefer to be able to record and re-record the sounds of the alphabet until I'm happy with the sound.

I'd need at least 26 buttons (for 26 letters of the alphabet) - probably aim for 30 buttons and therefore 30 sounds to be played back as required.

Skills: Electrical Engineering, Electronics, Manufacturing Design, Microcontroller, PCB Layout
