Nokia LCD/PIC based thermometer


Apparently I’m on a nokia 3310 LCD kick. [Coniferous] submitted this nice little pic project/nokia LCD implimentation. It uses a DS18B20 temperature sensor, a PIC 12F629 and of course, nokia guts. (We’ve gotten enough of these that I’m starting to consider a Nokia LCD hacks category.) The parts count is really low – this could easily be encased

  1. I don’t understand most of it because I don’t speak the crazy moon language it was written in, but I know a damn fine project when I see one.

  2. hahaha! my god, that translation cracked me up… int the second section, “Operator signature:”.. for what i’m guessing is operating temperature, it’s got “latitude mensuration”.. how?! then least stride temp? yeah, i know, translators will do this, what with so much to take into account.. grammar, local dialects etc… but it’s still funny.. or am i just very childish?

    anyhoo… great hack, if i had the skills to solder on that scale i’d even consider trying it..

  3. Those DS18x20’s are good sensors. Analog-to-digital is done over one wire, and they are fairly usable with the microcontrollers I use. I helped produce code to get these working on an AVR / arduino.

    As these use a bidirectional bus and each have their own unique “lasered” ROM code, so it is possible to pout many sensors on the same ground/5v/data.

    Another sensor to take a look at is an SHT11, or alternatively a parallax 28018 (which is an SMD SHT15 on a DIP-8 breakout board). These measure temperature and relative humidity at 14 and 12 bit resolutions, with good accuracy/precision.

    It would be nice to see a translated page. I’m curious about using an LCD in a project or two, something that outlines what is needed might help.

  4. very nice!!! this is a much cleaner job than many of the sloppy hacks we see on this site, and to top it off, it actually *is* a hack! beautiful :)

  5. 9 out of 10 stars!! this hack has all the necessary ingredients of a “good hack”—including pictures and schematics and a paragraph in croatian telling what each picture is about. I love the language barrier; but only in todays day and age where i can go online and find a translation engine—remember back when if you were handed a thing written in croatian you had to go to the library and look up each word?

    I totally love this hack…..Croatian and all. good work Will.

  6. Why do you think it’s in Croatian? Page is hosted on Hungarian domain name, so Hungarian language would be best bet. I can read some of it cause I speak Russian… Pretty neat hack too, but apparently page hasn’t been updated since 2004 :)

  7. .hr isn’t hungarian it’s croatian (local name of the country is hrvatska). translating it shouldn’t be too hard (for a person). i could translate it, but i have no right too. i’ll mail him to see if he’ll do it.

  8. Does he use a 3.6V or 3V battery? I think with 3.6V he’d be out of specifications of the display.

    I wonder how long the battery lasts, the display is quite power consuming (for an LCD), cheapo LCDs that you find in consumer products take way less power.

  9. A fully charged LiIon battery has 4.1-4.2V. I wouldn’t worry too much about it though. I know it’s out of spec, but I run 3310 LCDs at 5V all the time and they all still work. They’re dirt cheap anyway.
