I unfortunately plugged my shield in off key without noticing it and when I powered my Netduino it failed to connect. I tried to find the software reason it wouldn't connect rather than what could be wrong with hardware. Once I notice the shield was not plugged in correctly, I disconnected the power removed the shield and allowed the duino to cool. TOO LATED :o Well live and learn. From now on, I won't power-up without checking the connections. Oh well now I have to order a new one Just had to get that off my chest.

I ALWAYS triple check my connections. So far, I have not fried even a single component. I have gotten quite close though ;) Just ask my temp sensor that had a backwards pinout to the dumb datasheet....

I guess I shouldn't try to work on my board with distractions. Just did not notice the pins that were not in their sockets.

Hi klotz, No fun at all. It sounds like it got fried, but you may want to try erasing the Netduino (using the ERASE) pad and seeing if you can reprogram it. It's probably fried--but there's a small possibility of recovery... Chris P.S. Reverse power protection and a resettable fuse are built into the Netduino. And the odd pin spacing for shields helps keep pins in the right place. But while Netduino is designed to take a certain amount of abuse, it is possible to fry a pin (or in more extreme cases, to fry a whole Netduino). Most users will be fine--but it makes me sad to see one get electrocuted...

He's dead Chris.
No amount of protection can survive an unattentive user. Just got to excited about testing my two ethernet shields and didn't notice I had plugged it in wrong. The Seeeduino shield is wider than most so it is not as easy to see the pins if you don't pick it up and inspect it.
And of course I was convince I had checked it so I let it cook while I trouble shot the failure to connect. The Atmel was way hot, and I can't get any response from it at all except a very bad smell and lots of heat.
(Kind of reminds me of like Washington D.C. or Springfield, IL)
I'll mount this one on the wall with a note "CHECK THE SHIELD" hanging from it.
That's what overconfindence will get you.

Well you're setting new ground here, klotz. After two months of use by thousands of Netduino users, the first Netduino has been subjected to electrocution. There's not an emoticon sad enough so I'll just use three. :( :( :(

Sad news. I think a minute's silence as a mark of respect to a fallen comrade is required. Can everyone please run the following code on their Netduino.

using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;

namespace Minute.Silence
{
    public class Program
    {
        public static void Main()
        {
            Thread.Sleep(60000);
        }
    }
}

R.I.P.

But now you have a perfect board to practice SMD reworking (assuming you've burnt just the micro) Posted Image

Now there's a good suggestion.Since I am normally a software guy, where would be the best place to get a replacement Atmel? Digikey is asking $20+shipping handling tax. Almost the price of a new Netduino.
Any suggestion where else I should look?

Unfortunately, the Atmel chip is about a $20 chip (of course unless it is purchased in quantity). I'd say digikey is your best bet.

Just be lucky it isn't a ~$150 chip :P

In either case logic dictates that I order a new Netduino. $20 + shipping and handling and frustration of removing the old and adding a new > 34.95 + shipping and handling.
