I just got my Omega 2 in the mail yesterday from the the Kickstarter campaign. I did not buy a power shield. Instead I am trying to power it off the 3.3v rail on my Arduino Uno, and the Arduino Uno board I'm powering off of a PC USB port.
When I connect it this way, the orange LED lights for about 20 seconds and then turns off. My understanding from the Omega 2 getting started guide is that at this point I SHOULD be able to see a wifi network called Omega-B415 (last four hex digits of my device's MAC, from the sticker on the device), but I do not see it. Tried both with my laptop and with a "wifi analyzer" app on my phone.
It doesn't seem like the shield gets noticeably warm to the touch after 10 minutes or so of being powered.
In my photos you'll see some electrical tape on the power wires, but the connections are soldered underneath the tape and the tape is just to prevent them from shorting.
I saw another thread about sloppy soldering being the cause of Omega2s being DOA, but I carefully inspected my device and I don't see anything sloppy or any pads being connected that shouldn't be.
Is my device DOA, or am I just not powering it correctly?
Update: the Omega 2 is just more finicky about input power than I would have guessed. I eventually was able to power it off of a 3.7v cellphone lion battery
