    What would be recommended for a beginner?

    I'll spend about 70 in total for a bunch of stuff.
    Preferably from oomlout

    Currently picked out these:
    http://www.oomlout.co.uk/8-x-8-bicol...rix-p-233.html
    http://www.oomlout.co.uk/5mm-red-leds-x64-p-192.html
    http://www.oomlout.co.uk/5mm-green-leds-x64-p-193.html
    http://www.oomlout.co.uk/arduino-sta...rdx-p-183.html
    http://www.oomlout.co.uk/500-resisto...att-p-204.html
    http://www.oomlout.co.uk/pushbuttons-x5-p-196.html



    Is there anything I could cut back on/not needed?
    I have a soldering kit/pliers and a few left over electronics like transistors and capacitors. Been a while since I've actually done anything with them though.

    [edit]

    Found out the pack comes with a 9v battery cable. I'll remove it from the links list.
    Wow, those are expensive.

    The Chinese shit you could find in a local Thai electronic superstore would be dirt cheap compared to that.

    You could get most parts from old broken electronics. (except for the Arduino and batteries of course)


    Oh hey. Add me too, I've got an Arduino Duemilanove. With a DIP switch for switching off those TX/RX lights. :smug:

    The LEDs and resistors aren't bad, but their starter kit isn't worth it. Waaay too expensive.

    That's the same kit I have, and for what you get, I didn't think the price was that bad.

    Also, I'd love to be added to the list :3. I too have a Duemilanove.

    Mine arrived a few weeks ago. But I haven't had any time to really use it.
    Though I have blown 2 LEDs, was great fun.

    To jamie, the experimentation kit comes with motors, ICs, leds, buttons, etc. what you'll want to get from the store are some general purpose transistors and capacitors to go with it.

    Ok, I removed the box of resistors and was going to buy a big pack of transistors/resistors/capacitors I saw in a local electronic store.

    However I've been having some payment issues on the oomlout website. When asking for card details I fill it all in, then when it comes to confirmation, I get redirected back to the payment page, with this error:
    "10567 Invalid Data - A Start Date or Issue Number is required."

    When there's no box for that.

    I'm writing down a few simple ideas I could make with my arduino before it arrives.

    Quick question;

    How would time work with the arduino? Is it possible to have a real time?
    One Idea was to use a servo that comes with the starter pack, and have the kettle turn on at 7am.
    Would I just have to set it up and turn it on the night before, then in the code calculate how long is left before the servo rotates to flick the switch.
    Then comes in battery life of some thing looping constantly like this all night.

    You can just use sleep(timeinmilliseconds); to make it not do anything.

    You could theoretically put it to sleep for 24 hours. Only problem would be to start the timer at the right time. Example: Turn on your arduino exactly at midnight, add a sleep of 7 hours, add a sleep of 24 hours, repeat sleep of 24 hours.

    Yes.

    I am pretty sure that energy consumption is pretty low when it's sleeping.

    Delay can't be used for anywhere near that long, nor does it put the device to sleep, so it would still be consuming full power. The best way to sleep for long periods of time is to use an external RTC IC(Real Time Clock) with an alarm function tied to an interrupt that wakes the Arduino. A RTC IC is also the only really reliable way to tell the time.

    session_start();
    
    $_SESSION[ /* blah */ ]
    

    you'll need to implement the ip-boundness and the expiy yourself, but I'm
    sure you can do that

    !!! ATTENTION !!!

    Do not short circuit batteries with your mouth closed, your ears will thank you. Also make sure none of the ends is pointing towards you.

    I did exactly that mistake, and here is the result:
    Picture

    I connected 5 of those batteries with each other, and this one exploded after 10 seconds. It flew with sonic speed straight into my stomach! ouch!

    I'm a noob. I screwed up my protoshield by soldering the wrong piece into the wrong spot.
    It's one of those black things you put pins and wires into; I put a short one where a long one should be.

    Gonna need to get some solder sucker.

    Or solder wick, or just heat the parts up and pull them out.

    I've tried heating it up and pulling it out, but by the time I take my soldering iron off one pin, and heat up another, the last pin is already solid again.

    And it's 5 pins, so I can't just start yanking one while the other 4 are connected.
