I ahve a few ideas that i want to help develop… incase someone else dont want to pick it up - but i have never done any java programming, so what would be the best environment? in running this on a Pi if it makes any difference.
My ideas are:
16x4 (or 16x2) i2c lcd display to inform user about progress, when its done ect… perhaps backed by either a SOAP/REST or httpget service
the mask… creating a UV sensitive device that can measure the UV light difference in grid, and transform this into the mask used…
The light measureing mudule would be a sensor like this:
and then connected to the PI using a ADC like
And then a simple button that are being pressed when the sensor is in a cell in the grid.
