A new component arrived in the mail. Very tiny. One could accidentally swallow it without chewing. I like its name very much: Thermocouple Amplifier MAX31855 breakout board (MAX6675 upgrade) - v1.0. It sounds very serious and 'MAX' seems to suggest that one shouldn't underestimate it just because of its size. I also like the 'Red' and 'Yellow' reference on the blue board. Bold enigmatic statements on a blue board. I can see it on display in a modern art museum, on the wall, a Swiss magnifying glass suspended on a wire beside it.
By the way where did the blue come from? I remember such boards with the connections printed in thin copper, often home made and etched out in acid, used to be rusty-yellowish and later green but all of a sudden it's blue all over. Do the really hip board designers call this Arduino Blue?
