Glass Block Display is Growing
CJDavis and I were at the hive until about 1:20 am this morning working on finishing up a second strand of LED lights for the Glass Block Matrix LED Display.
In this image we are diffusing the LED’s with a sheet of paper towel which causes a nice soft glow, however it greatly reduces the brightness. Therefore we are leaving the paper towels off even though they make for a great picture and viewing experience from inside the bathroom.
We have had some technical issues with both the RGB LEDs and the wiring system we are using. A good amount of the LED’s seem to have an issue where they will turn on even when the anode wire is not connected to anything. We are talking nothing, like it is just soldered into a proto-board. Current speculation is that either the LED’s are bad or the proto-boards are bad.
Another problem we have been having is that originally we were using Cat-5 to wire up each anode for the 8 LED’s in a column, however the current in the twisted pairs was enough to induce a current in the second pair causing issues with LEDs coming on when they are not supposed to. This is a fairly limited problem so far as the LEDs only glow faintly. In any case we are altering how we wire up future anodes.
