Välkommen!

Där är massor af "full fart" på detta forum - men det är lite trägt på "Scandinavian". Antagligen är dina engelska bra nog for at vara i Aussieland smiley så du får snabbare svar på dom andra områden på dette Forum

Two other links of old-meets-new - I just fell across these today, I wasnt searching.

i do not speak english very well.
Fortunatly, we only need to read your written English smiley  (that was a joke)

my question is, if that can be made, of course, and if it can, if anyone can tell me some things about the pump or dripping system i am looking for
As a project just about perfect for an Arduino, in particular with a small keyboard/LCD to see/adjust the limit settings.

The Arduino is just going to turn a pump or valve on/off, irrespective of the drip/pump choice.

With the same geeks, only a bit older this time round.   smiley-razz
ROFL - that one almost brought tears to my eyes

You know, looking at the specs for the BBC Micro
(and other nostalgia)

When I heard about the Pi on a mailing list a long while ago, I wrote a reply, but didn't push send. I didn't want to appear as the grumpy old man who "has seen it all before". (It was in danish so you get the translation) This was in November last year.

Oh... well, well, first I heard of that news. One cant keep up with everything.

On the other hand - the first introductory paragraph says:
What’s a Raspberry Pi?
The Raspberry Pi is a credit-sized computer that plugs into your TV and a keyboard. It’s a capable little PC ... high-definition video. We want to see it being used by kids all over the world to learn programming
.

That reminds me of the ads of the sc/mp (I had one) and the Spectrum (had one of those, too) and so on through the 70ies and 80ies. The only difference is the number of pixles on screen, and the price is (inflation adjusted) ten times lower.

(signed)The old man, smiling a little overbearingly


What I guessed was likely, but didn't write, and this thread makes it clear, is; it is the same geek/hobby/hassle again. Just with more bytes and a faster CPU.

-48 was right...
But -'0' is completely unambiguous, and does not require consulting an ASCII table.
Indeed. I was hinting at the commented out code of the OP. You could have suggested the -='0' in your answer earlier smiley-wink

If your code is sending the int 1860 it will send four bytes : 00 00 07 44  ('cause that is 1860(10) represented in hex/binary/machine)
If your code is sending the string "1860" it will send four bytes 31 38 36 30 ('cause that is the ASCII codes of four characters)

The threads says you've tried both, but neither way will work with the decoding you are doing in the Arduino (-48 was right...)
713  International / Scandinavia / Re: Hjelp til å lese av ei fotocelle? on: July 01, 2012, 04:23:02 pm
I teori ganske enkelt - du putter Gnd/0v fra din fotocelle til GND på Arduinoen, og putter fotocelle output gennem to modstande på noget der giver et 12/5 forhold - f.eks. 12KOhm,4K7Ohm - til GND. Så tager du forbindelsen mellem de to modstande til et Arduino input ben (digitalt eller analog). Det kaldes en spændnings deler.

By the time it arrives I'll have misplaced my marbles.
So you were spared that, Nick ? smiley-wink Seems that what you won on the shipping, you lost on the configuration smiley

I've bookmarked this thread - lots of things to remember in another 8 weeks (according to their ship-estimate) - keep up the good work fellas, and post often  smiley-cool

I can not confirm or deny your guess, AWOL.

Sounds like fun, can I join your hacker space, I don't live that far away smiley
So what's your definition of far away?  Mars, or Proxima Centauri? smiley-wink
All things are relative. I've been to Sydney. Cant be longer the other way smiley But then I did not pay the ticket.

A worldwide company making consumer electronics shutdown its Copenhagen branch a year or so ago. You cant just leave a campus of three big office buildings and 1000+ employees, most engineers, overnight, so by about now they are getting close to actually hand the empty buildings over. As a socially responsible company they are handing some of the leftovers to organizations like schools, needy homes and so on.

Of their R&D stuff, most of the good/expensive and in particular anything propriaritary equipment is handed to their other offices around the globe, but then there is a leftover remainder which is just "rubbish". They just can not be bothered to spend a year selling it on ebay. (If I did it it would be fulltime and yield a respectable income - there is so much!) My local hackerspace has been allowed to look at the leftovers and see if we can reuse some.

I think we now have enough SMD components to last us until that technology is as old as the radiovalve, we've have dozens or more movingboxes of the stuff. Similarily we filled a car or three of sorting boxes/cupboard/drawer systems of all shapes and sizes, and some odds and ends. The best bit was a few "robots" (small EM-radiationproof cupboard filled with pneumatic and electromechanics that did some assembly or stress test) for dissasembly of parts - and som large enviroment chambers also semirobotic - but the frames cam be easily reassembled into new boxes for our projects.

We were 8 men sorting, dissambling and loading into our trailers this afternoon and we will continue for two days more, or until we no longer can store any more in our space. We'll spend weeks giving it a second sorting and probably throwing half out. (What on earth does one do with 5000 small SMD induction coils?) It has been a great day, though smiley

Ohhooh - I've got to reply to this thread, too. Another tiny step towards making the first K post...

OK, so today I was invited to order. I've forgotten what the raspberry was/is, what I wanted one for, why I was waiting. Still, I've had a great day today, so I just hit the "yes, send me my Raspberry PI kit" - €64 including two SD cards - 9 weeks delivery. By the time it arrives, I might use it to ...<enter irrelevant and funny use here>

The blue smoke MUST remain inside the Arduino at all times, else it fails ...  smiley-cool

If the Arduino chip got warm, warm enough to smoke, then you did not connect your battery or servos correctly.

WIth nothing but the USB port connect to your Arduino board you can try to upload and run the blink sketch. If it works you have been lucky.

Or did the smoke come from something else than the actual microprocessor chip?
