So you are happy that you got a new Rabbit[^]?

Do you know any good resource where and how to begin doing something "interesting" with embedded systems (for a complete novices)?
It always fascinated me but I'm too attached to the high level languages. Wouldn't mind learning something lower level tho'. Build some kind of T2000 and end the suffer of all the humans (-.

Try the Arduino, it is pretty dumbed down, and makes a good/cheap starting platform.
Once you outgrow that, your choices are almost unlimited.

"dumbed down" is just what I need (-.
http://arduino.org/[^] It looks interesting and cheap, nothing to lose in the event I'll just throw my hand up after a bit.
Thanks.

This line of products is really meant to use a custom version of C for programming. It would take a lot of work to program it any other way, though there's no reason it can't be done. There are several products available for embedded systems, though, and lots of books to learn from. The Lego Mindstorm system has always seemed to me a great introductory tool, and if I didn't start this venture with a product in mind, that's the route I would have gone.
When you're shopping for development kits for your use, keep an eye out for gotchas - things you didn't expect to need. For example, most of the low cost units I've looked at in the past have failed to mention in the advertising that you need an external EEPROM programmer to write your code to the hardware. That can add a lot of cost to the project, not to mention the hassle of removing the chip, programming it, installing it and testing the code, then having to repeat every time you make a change. This Rabbit device comes with a built-in programmer that compiles my code directly to the EEPROM via the PC serial port - no waiting! Some will expect you to buy the software for programming the device, some have very little documentation available. Do a lot of research before you select a platform.
Alternatively - if you're a masochist - you could learn low level programming the way I did. Get a 74181 ALU, a 74194 register, some flip flops, LEDs, DIP switches and a power supply then design your own microprocessor. Of course you'll need to design your own instruction set using register transfer notation, create your own assembler, compilers for your favorite languages, and a few other niggling details... 
Have fun!

I think for starters I'll go with Arduino mentioned by leppie. It looks overly simplistic, but who knows, I may be dumber than I think I am (-. And it is pretty cheap, I'm thinking about this one. It's only 60GBP (including shipping)! So in a worst case scenario it'll be a nice pencil holder.
Thanks for all detailed explanation Roger.

That's a great little kit! I think you'll have fun with it, and probably learn lots while you're at it. I like all the peripheral goodies that come with it, too. Some of those would cost a bundle to purchase separately. Good choice!

So, we donate to save the children. We saw them in a shopping centre, and, while we give a fair bit to World Vision, I was keen for us to support more than one group. So, I offered to give $200 a month, and they asked me which of three areas I wanted it to go. Then they suggested splitting it between all three. I said sure, and next thing I knew, I had to fill in three lots of paperwork. PITA. A few months later, I got an email, telling me that they had noted my desire to stop donating. So, I called and told them I had three accounts and I had closed none. Fast forward to today.
I got two tax statements in the mail. I called to ask why I did not get three. The two I got were for two accounts that were never reopened, they had stayed closed. The missing one, the biggest one, probably came in a copy of their magazine, which I'd have thrown out ( as well as having requested them to not send it ). They are sending me another one, and reactivating my two accounts. My question is, all I am trying to do is give them money, how could it be so hard ?

If you send me your money, I promise you to never send you anything back (as a matter of fact, you will never hear about me again in your life  )

because like many charties they turn in bureaucracis and gather all the inefficients required to justify (and pay for) their own existance
My woman works at one such charity here in Brissie - its disgraceful what goes on.

Yeah, I believe it. The flip side is, when I was talking about joining a charity, so many people here said things like 'you know only 10% of the money helps people ?', and it occurred to me that, inefficient or not, making a donation helps more people than not making one.

Most people who work for almost any given charity do so without payment, but it would be impossible (and a lot more wasteful) to try to maintain a large charity without paid professionals, so I have no problem with helping to pay for them to run the business of the charity effectively.

I know that there are a lot of so-called charities that are like that... Trick is to find one that isn't and donate to that one!! My choice is Camp Quality (clearly).

Yup. There's an online database showing the percentage of money actually used for charity vs overhead for us charities; do you have something similar to vet where your money goes?
IIRC the worst I've seen was about 70% overhead. 
3x12=36
2x12=24
1x12=12
0x12=18

Never give to charity.

I see, why positively reinforce bad behavior when you can positively reinforce good behavior. If anything, we should reinforce the rich for being rich by giving them more money. Perhaps the poor will follow suit.
