Powering the Yun from AC thru Vin

I need some help. I'm having trouble powering my Yun through the Vin.

110 VAC --> transformer --> 13 VAC --> Rectifier --> 12V DC --> 5V regulator --> Vin

I've got a steady five volts from the regulator, but when plugging into ground and Vin, I get nothing. Do I need to source a certain amperage before the Yun will run? If so, what's the best way to do that?

Many thanks.

BTW, it will power thru USB, so the Yun itself seems to work fine.

the linux side needs 250 - 300mA

So does that mean I have to have 350 mA flowing before I reach the Arduino? What's the best way to go about doing that? Sorry for the noob questions.

why don't you take a 5V mobile phone charger and then strip the ends off and connect the PWR and GND directly to the VIN and GND of the device.. seems an overkill to build this yourself when it already exists in abundance. :) or, you could just use a USB charger and plug it into the USB port!

Ardiri, good point, and I'll probably do so down the road. However, right now I'm just beginning to get into the world of electronics, and I want to understand the HOW as opposed to just sourcing pre-built solutions.

Bravo! What a great attitude, it will take you far! :sunglasses:
