Re: EtherTen running hot

I finally powered up an etherten last night (having had it sit around in a box for 6 months). I ran the webserver demo code, all worked fine, but man does that wiznet chip run hot! I'd guess around 55degrees, can hold a fingertip on it, but only just without pain. I then loaded some other code that ...

Re: Can the hall effect sensor show polarity?

Typically you'd use 2 sensors, slightly offset, to get direction.

I've bought a few hall sensors with the intention of making a "fridge magnet linear quadrature encoder" but haven't got to playing with them yet.

Re: is my ethermega dead?

you may have just zapped the auxilliary micro that runs the USB comms, or fried some IO pins. I'd put in a little more time trying to bring it back to life.

But its your $100, assuming you want to keep going with the project.

Re: Defective 8 Relay Shield?

Hard to tell what's going on from that photo, but as far as I can see the resistor for the led is plugged into a row that is not connected to anything, 2nd row - should it be plugged into row 3 ? It's always good practice to start with a sketch schematic of what you're trying to do, then before powe...

What ?! There's xmas decorations that don't rely on an arduino ? I won't have a word of it.
You need to educate your wife as to what is a real xmas decoration.

Terminal shield to suit EtherMega/EtherTen

so I don't have to hacksaw/butcher out a rectangle above the ethernet port. http://i49.tinypic.com/24mc1fm.jpg Yes I can use another set of headers to get the extra height, but I've been bitten a couple of times with dodgy connections on multi-stacked shields, especially when there is a 'headers for...

Re: question about driver

Not exactly related to the OP, but I thought it best to just add to this thread rather than create a new one. I just plugged in a new EtherMega v2.0. I can't see what version my old one was, but this one is slightly different, having the micro USB plug (which feels a little tight, but I digress). My...

Now I've noticed that Pololu use it to indicate GND. Go figure.
I guess it means "there's something different about this one", i.e. there is no accepted standard.

Re: feedback on protomega

Nooooo! I just realised the inset duplicate IO pins along the long sides of the board don't line up with anything . They're not a multiple of 0.1" from anything, foiling my cunning plan to straddle connectors http://littlebirdelectronics.com/products/spring-terminals-pcb-mount-6pin for access to IO ...
