Thank you everyone, that was it (too long wires). So anyone reading this, your device should consume +-250ma after 30 sec or so and goes back to +-170ma. If you have the amber led turning off for 1 sec, that is because the omega is rebooting .

It would be nice to specify this information in this page:

Even in the pictures it looks like you are using long & thin wires...
Cheers
