Anyone using electronic transformers to power the nodes?

[ferpando]

I got yesterday this kind of transformer to test how it behaves

You are aware the output is AC not DC ?

What do people generally use for AC-DC conversion from mains? (not socket bur perhaps siphoning from light supply etc). I have tended to recycle old phone chargers but wondering was there anything of a smaller form factor and perhaps really commonly used.

Thanks!

Yes, I know it needs a rectifier.
I got this because it is small and gives 5A so it might be good for lots of leds

It needs a minimum load onthe output, in order to function correctly.

If this minimum requirement is not met, the output couod become unstable, and self oscillate. I've Seen this with an electronic transformer for halogen lights, where i use led lamps instead. Needed 1-2 halogen spots on it (it supplies 5 spots in total) in order for the electronic transformator to work correctly
