Blue LED-Candle Birthday Cake
Posted October 1, 2012 by Chris
“Pure awesome! I have the best of friends who made this for me. 30 bright BLUE LEDS hot glued into straws, wired up to a driver circuit, then manually poked through the bottom of the cake! Man, it must’ve taken some planning and time to make this! The whole thing was powered by six 9-Volt batteries! All lead-free solder a plus.”
