Quote from: ivorydrops on Oct 24, 2010, 06:26 pmI don't mind doing one LUXEON on the circuit, but you will have to tell me how to modify the circuitry on your specifications. Though, I will admit that I like the fact that I can get all the parts locally and not have to buy one LUXEON piece and pay outrageous shipping for one piece. Also, futureelectronics.com appears to want to sell lots of 100 though they mention to call for single item purchase. I think the $8 you mention in your price list is what you got when you called for price per single item. What was shipping?Alternatively, I could use any of the ones below. This might make the difference of shipping from getting at futureelectronics.com and having instance bliss on acquiring the parts. I am sure other readers would appreciate that option.Anyway, here are other choices I found, but personally I am not partial to these specifically if you happen to notice a better choice.5mm High-Brightness White LED ($2 at Radio Shack)# High visibility, 5mm Round T-1 3/4# Intensity 7000mcd (typical);viewing angle 30°# FW current 25mA; FW supply 3.3 (typical), 3.6V (maximum)# RoHS compliantOR5mm White LED ($5 at Radio Shack)# Typical Voltage: 3.2V# Typical MCD: 1100# 20mA (max)# Viewing angle: 50°

You can omit the large 5W resistor if you aren't using LEUXEONs. The value of R6 would need to be changed to approximately 270 Ohms.

You can omit the large 5W resistor if you aren't using LEUXEONs. The value of R6 would need to be changed to approximately 270 Ohms. Are those the only changes? So, If I have R6 to 270 Ohms, omit LED3-6 and omit R7, all I would have to do in the end is hook up the LED to TC2 on the diagram and hope the LED does not go "bang"?
QuoteIf I tried this, I might split the tracks to specific sounds. For example, I might have the left channel have a consistent sound that makes the light flash evenly and then have the right channel do the proper sound. It does not look too bad though.
