that would be perfect David,I'd pay for that, where I need to put it is in the roof in a small gable window it needs to be able to autoplay and loop remotley on power onThat shouldn't be too difficult technically. Maybe an Arduino Nano would do the job at minimal cost.
Bugger! ok which Excelvan projector? looks like heaps of different models on ebay and how do we make this work? short of spending $1000's I did look at a dell projector that looked like it would have work straight out of the box this way but it was way out of a reasonable price rangeWe've been talking in chat and it seems that the key presses to select the files is convoluted so probably not viable.
There's also been discussion on the Excelvan projectors that seems to be better resolution and brighter than the Arlec for less money!
