Greetings all.. I've developed and created the "Poolroom Scorekeeper Mini". whoo hoo.. well after hours and hours of work developing and then printing a custom enclosure, tests show that the individual numbers on the display are too small to see while streaming online.
Here's a quick video showing the completed product:
see attached image to see what it looks like when viewing online.
also see attached image for the current LED modules I use.. they are the standard 8*8 32x32mm times 4.
Its obviously too small to see and I need to make the displays BIGGER..
what would you suggest?? I was thinking 8*8 but making them 5mm LED size which would increase each letter by almost 4 times.. I'm sure there are many other options and I'm wondering how you would do it.. should I use a LED screen or maybe paper display?? any suggestions REALLY APPRECIATED!!
please also keep in mind the scorekeeper connected to the pool table is pointed almost downward so i will have to make a base so its tilted upwards which should increase the readability of it..
here is code for those interested..
