Hey does anyone know where I can get those nifty little heat sinks like the one included in the breadboard power supply from Arduino?
Thanks
Almost any on line electronic components supplier has a vast number of heat sinks, like:-
A drill, a hacksaw and a bit of patience would likely yield a usable heat sink from an old hard drive frame. I sometimes use bits of aluminium angle that I have lying around. Not pretty, but serviceable, particularly for non-critical applications.
