Today we ran the LED matrix off the 3D printed panel on the side of the LED matrix.  Also tested that the USB keyboard port works.  All the AC fans work.  Now we can close up everything.

I the picture you can see the two AC power rails.  Later the two AC fans and the power supplies where connected to these.  I had to move the power supplies from the location in the picture the wires where too close to the side mount of the matrix.  Move the up about 30mm that solved that problem.   Our 4H Fair is coming up in Aug, the plan is to mount this in the rabbit barn late in July.  I hope to post some pictures of the kids working on the project but first need to get parent permission.

      The programing is being done by one of our club members.  He has done a great job.  One items I'm working on is he is storing the fonts in ram, I'm going to move them to flash.  We are having problems storing new phrases, due to running out of memory.  The plan is to get all the physical parts done first.  Other kids have helped with the work working, planning, soldering.

     The environment this will be located in does not have AC, and the panel needs to be running from 10 a.m. - 10 p.m (11 p.m. on weekends) for 10 straight days.  This is main reason some parts of the machine have been over engineered.

 Left to do

    1.  apply diffuser

   2.  attach mounting brackets

we are on schedule.
