I have made them in the past but never one of this size. Can you believe that I was 1 LED short of having to open another 100 pack of red LEDs. Now I have 99 left for another project. Would it make any sense to add more columns or leave it alone at 16x16? Time to go to Radio Shack after work tomorrow. I have about 2 inches on the left and right sides of the perf board (LEDs are in the middle and to the top). There is about 1 1/2 inches of perf board on the bottom of the LEDs. This should leave enough room for the transistor/resistor circuits on the right side of the LEDs and ULN2003 chips on the bottom (under the LEDs). I should have my SX52 proto boards on Tuesday which will leave me tomorrow night to solder the driver/buffer circuits and run wires or something to the SX52 proto boards. I very much appreciate all the help and encouragement today to you guys and especially JonnyMac.
