When you have an arduino project with the lpd8806 RGB strip and you go to hook it up to your benchtop power supply, I suggest using +5V and ground for your power connections. Using +5V and -12V is *not* a good choice.
It trashed the Arduinno, but amazingly the last 20 of the 32 LEDs on the RGB strip survived having 17V across them.

I have often found that the most expensive parts die first in order to save the least expensive parts. How noble of them.ericgu wrote:It trashed the Arduinno, but amazingly the last 20 of the 32 LEDs on the RGB strip survived having 17V across them.

Re: Important safety tip
Yup that's totally true. The corollary to that is the amount of blue smoke released is inversely proportional to the device's cost.
