Thanks so much for responding. You are a gem. Your dedication to this long standing project is amazing.

I do indeed have the correct driver installed.

I solved the problem by scouring the forum and collecting what I call your kernels of wisdom regarding proper set up and operation of the sandbox.

With the addition of -rer 10 110 to SARndbox’s command line I am now getting excellent rain response by holding my hand with fingers spread (very important).

I added the configuration files that you explain in your “AR Sandbox Post Installation Instructions” which map the 1 and 2 keys for calibrating the projector and for the adding and removing water globally. It works great.

One question I have is related the the height of the hand over the box. If my hand is held low, the software thinks my hand is the surface of the sand and maps it white which obscures the image on the sand. I am guessing that the setting of -rer 10 110 might not be quite correct. What setting should I use so that a hand held over the top won’t be color mapped as snow? Is this a result of the way I calibrated?

I will be showing off our AR Sandbox next weekend at a Washington State Science and Engineering Fair at Bremerton High School in Bremerton Washington. This Sandbox was funded by several STEM grants to the Bremerton Historic Ships Association, aka the USS Turner Joy Naval Ship Museum.

Thanks again for your continued support of this great educational tool.
