  • where can i learn how to build one of those thx.

    very nice

  • It seems that you dont have heatsinks on the BD140. Don't they get warm?

    Thanks

  • mate this looks absolutely awesome, based on your calculations what current are you drawing from the LED's and for what reasons do you not use transistor arrays for the LED's, it looks like you could be overpowering them

  • nice, how much price?

  • Nice job....I like it:-))

  • gayest song ever

  • Very nice done! Amazing
