That was an old project I did a couple years ago:
A short video (sorry for the low quality):
https://youtu.be/6P0OKhac51g
It was suppose to be an electronic hand-shower, it worked but it never moved from the test stage.
The OLED display (96x64) is controlled by a PIC18F4525 programmed in C plus some (small) parts in assembler to improve speed.
The quality of the display is far better than it seems from the pictures... anyone is an expert photographer ?
The sensing of the finger is obtained by an array of IR led plus relative fotodiode (you can see them in the pictures).
One big problem was aesthetical. How to hide the sensing circuits ? I wasn't able to find any IR transparent plastic (but opaque to visible light). Any idea ?
