I don't suppose anyone knows a good (think cheap) source for a roughly 10"x16" hunk of heatsink / finned aluminum?
Sucks when you realize when you complete a DIY project that your design was wrong from the start. Acrylic is a very effective thermal insulator... I need to get the heat away from the LED lighting I'm going to use on the new 5g tank...
8 destroyed hunks of acrylic... over 2400 holes marked and drilled by hand and at the end I realize the error of my ways.
