i think e-mail should be enough, as those won't be found by other newbies here.
to shorten the agony of seeking my address, here it is: mctom@o2.pl |

i got another brilliant idea.
how about using mobile phone display? those must be power-saving, naturally, and i've heard somewhere that nokia lcds are very easy to drive. can someone confirm that?
by the way, i skimmed through the auction portal and they are also cheaper.
perhaps i'd use color display then...  |

Of course that's a brilliant idea. Many other people had it too ! 
Nokia displays are great for this purpose:
Nokia 3310: monochrome
Nokia 3510: color, but not very brilliant in colors. Reflective type
Nokia 36something: great colors!
All: SPI-interface, 3.3V
A lot of information on the net

i guess what you meant is 3660, but i've found one, too expensive  but anyways this idea seems to be the best, and if you claim that most of them should be atmel friendly then i'll choose most fitting model myself thanks.
SPI-interface are the good news, i guess?
while googling my new idea i found some voices that the driver chip will be needed. is it true? |

Depends on what you mean: these displays have a built-in controller, that's what makes them so nice to use. The type of controller depends on the type of display, and for the Nokia3510 there are two types with each a different controller: Philips and Epson. They did so to make it simple
The displays operate @ 3.3V. The simple way is to have the AVR on 3.3V too. If the AVR is @ 5V, some level-translation is necessary.
You say in your signature: "remember I'm just a beginner!". I wonder if it's wise then to start with these types of graph displays. But of course it's all up to you.

i've been thinking on supplying minutes ago, and i settled that everything will run 3,3V, avr and the rtc (i already got) should work on it ok. i'll just have stabilizer or sth, because the supercaps i have are 5V max.
well, it's not wise to begin with both graphic LCD AND asm. but i'm quite confident as i've done lots of coding stuff before and i've got the whole holidays to spend on it
i understand that each controller needs another approach and it's up to me to seek for their datasheets/definitions? |

If you do a search on this forum and google around a bit, you will find all you need, and if I can help .... you know where I am hanging around
Cheers, and happy holidays !

that's what i mentioned pal, i guess no one's collecting this stuff.. thanks and see you!
phew... seems like i solved all problems for now. i'll see you later then when i get into mi first asm obstacle
see you and thank you all for your help. |

MACTOM
I just had a funny idea. If the solar cell does not work out, I saw in a magazine a miniature steam engine. I am going to buy it as I have seen them work in the past. The are really cool. The one I am buying is from England. you could connect it's flywheel to a small dc motor and capacitor and generate enough dc to charge the supercaps. Then when the engine needs refueling, the supercaps take over until the engine is restarted
Like I said it was funny........hmmm i see a project in the future

i think i have somwhere a 3.5ccm ether engine used to run models of planes. my dad bought it years ago but never tried to run it. hm.. solar cell i bought is 2.5x5cm so if this won't work i'll probably use a battery as substitutuion.
i'd love to use that engine, but i think that using heavy engine, fuel tank and dc motor fits stationary and outdoor-operating projects more. it fumes and is noisy, which makes it not indoor-friendly power supply.
and as that's a completely freaky idea, i guess i might use it in the future thanks! |

| no no no the engine I am talking about makes literally NO noise. not a model plane engine, those things are a horror show. What I was gearing at was a binary clock that could run on the little engine. Would make a great item to sell as a desk accessory in one of those high end gadget mags. |

are those engines more or less like the ones presented here?
http://www.tinypower.com/store2.php?crn=56&action=show&show_products_mode=cat_click
i think you mean smaller ones. or not? please post a link to a webpage about the one you got, and i'll search the auctions.
oh, and jim - i guess you forgot sending me the init files you promised.
by the way, this whole thread has gone crazy. we set off at battery packs, through solar cells, tremblers, supercaps, and now discussing steam power  how about miniature nuclear reactor? lol |

Yes, those are the engines. Personally i like the idea of using one of those over the solar cells better. The sucko is the cost. But, considering the amount of cells you are going to need to run your gizmo it is not that bad
I will send the init file tomorrow
sorry about that

actually i'm going to run it on single $2 cell polish price naturally.
but still, those engines are tricky. i couln't find any in any polish e-shop. and i'm not going to spend two months's wages to buy one
but i'm thinking of that motor i have. and summing up, it's useless.
any other alternative sources of energy? how about making an use of kinetic forces of sewer stuff? |

today it's a windy night. guess i'll consider installing a fan-based generator outdoors. well, i'm living 300m away from the baltic sea, that's the reason for heavy blows.
but i'm not using it to run the armwatch
got another idea. if someone's living near the eastern baltic coast, perhaps we could make the marconi's experiment again? isn't bloody-org from estonia? gotta talk to him bout it someday. |

| yes I am. I live 2km from Baltic sea. (currently am 1km from it). But what's that Marconi experiment? |

marconi was the first person to transmit a radio signal over the atlantic sea - from ireland to canada. during this experiment the current weather condition description was transmitted via Morse protocol
that should be easier to do on a way shorter distance. but well, it's illegal now i guess |

ok, maybe during the summertime i'll find a group of enthusiasts and mount the receiver based on marconi's project plans ;P
but you'd better aim the sender directly on poland, otherwise the russians might be angry :/
how about asking the discovery channel for sponsorship? |
