Currently there is not serial port config implemented on Due. A year ago the people from Arduino opened an issue but still empty:
Just how well is the Due supported? And if the Due port is not complete after all this time what does that say for the other new boards?

Doh, yes that's right, I was mixing .print() with .write()

I'd forgotten about that IDE feature, thanks for reminding me.

Love the Commando, that takes me back. I never had one but guys I rode with did.

Serial.println("Inc Value:");
  Serial.println(increment);

But then when I increase it, the serial monitor shows "Inc Val                "
then nothing.

Bizarre.
Not bizarre at all if "increment" is a small value because non-ASCII characters do not print  with the serial monitor, try

Serial.println(increment, DEC);

Not enough spec headroom.  10KW would have been cooler.
Probably, but a lot more expensive and this one just turned up on Gumtree at the right time (thank's to Paul/rockwallaby for finding it). I've only done a few test welds but it's working pretty well. Even at 150A the gennie hardly misses a beat, but the breakers trip. They seem happy at 120A and for the things I normally do that's plenty, but I will look into those breakers because at full noise the welder should need around 13A+losses and that's under the breaker size AFAIK.

do you have plasma cutter to go with it to cut the windows out.
I'm very tempted to buy one, they are about $800, I am having a hard time justifying it though as a grinder can do that job easily, that said I could find I go through $200 in blades smiley I am also building a roof and may have some clever counter-weighted lift-up walls, a plasma cutter would be very useful for that. As with most tools they aren't worth the money for a single job but over the years you really do get your money's worth from them.

Generator..   noise pollution in the bush..   
Can't be helped, and worth it not to be connected to the grid IMO.

I don't know if HART is worth it (maybe in some industries) but 4-20mA would be I think. I've just done a board for industrial control that required a current loop interface.

That PLC software is really expensive, around $5k per license I believe although I've never bought it myself.

So in an update on my workshop build here are my latest two purchases. First is a new MIG welder



I need this to make the window frames etc. But it needs a power source of around 6-7000 watts and we live on solar with a 3300-watt inverter. What to do? I know, buy a nice big generator.



7.5KVA of pure joy smiley

So work on the mancave Arduino R&D facility will begin soon.

So is it possible to create a "background task",
It should be but I've not done it on an Arduino.

Maybe turn things around and make the sending of chars to the machine the background task, interrupt driven so it never gets blocked, and the main loops polls the buffer and gets another 512 bytes when required.

You could set up a timer to generate the periodic interrupt or use the UART's Tx empty interrupt.

Those PSoCs look real nice, I got a CD with the dev software a while back but haven't installed it yet. I'm waiting until I get my workshop up and running so I have some space for tinkering.

So many eval kits, so little time :-(
It's quite amazing what's available these days and all free or near as dammit to free. I don't know if it's better to play with everything or really get to know one family well. You are obviously going for the first option smiley

A Raspberry Pi smiley

Sorry I have no experience with video, but at present I don't think there are any Arduinos up to the job although it may depend on exactly what "processing" you need to do, how fast you need to do it and what resolution the video is.

Would I be correct in assuming all this?
Yes that's correct.

@Rahere, what you say is correct for a real product, but I think well outside the brief for this project (I gather it's just to be displayed to a class) and also well outside Kando's ability at present. Also proper failsafe and fault detection can double or even triple the hardware required, Kando is worried about the cost of an extra diode smiley
