LED update
2005-10-11 by tmoravan
I finished the LED refit on my P3. Just need to get a decent photo of it up. I ended up using some RGB LEDs and cutting off the green leg. That gave me a Red Anode/Common Cathode/Blue Anode configuration that was a drop-in replacement for the original red/gren LEDs. I used the RGB LEDs with a diffused lens from www.superbrightleds.com (part # RL5-RGB-D, $1.49 each for 16). While I was in there, I replaced the current limiting resistors R6,7,8,9 and R10,11,12,13 with slightly higher values to make the LEDs less bright. I ended up using 470 Ohms and 330 Ohms, mainly because that's what I had in stock, it made them dimmer, and the color separation was still very distinct. Using the stock resistors, my eyes got very fatigued after a short period of time and the PLED screen looked dim in comparison. You may need to experiment to get the values right for you. (I made up a small test board first so I could plug various resistors in and see what they looked like first). I also updated both manuals (Colin's and Paul N's) with the new color information (amber->magenta, green->blue). Much better now.
