You may learn from well described EPR Bell experiments like this one from A. Zeilinger
There are 3 documents, the main one describes the apparatus, the second gives more details on the calculus ( it is on the right at Ancillary files ) and the 3rd is the big file of the recorded datas. You must write to the authors to get the latter.
It is considered as the finest experiment. You can get inspired to create your own reduced device and adjust your analysis methods for a yes / no answer to your main question, that is different from the EPR one.
Indeed, you will not be interested by the hidden variables evidence but by the correlations themselves at 0 and 90°. So you may conclude that you need something very light. But you will face difficulties and learn a lot from these documents.
