Wow, had you put this much effort into YOUR problem, you could have put
a SoC on a board and written the page of code it would take to suit your
problem.  The BALANCE of the time, you could have ASSEMBLED the boards
into boxes!

It's now 27 March.  Your initial post was 17 January.  A productive two months
for you, eh?
