Arduino Watch with Nokia 3110 screen

Featured
Picture of Arduino Watch with Nokia 3110 screen
My goal for this project is to make a watch with selectable dials, stopwatch and millidays.

This idea started with an Aprils fools prank about metric-time. (http://www.youtube.com/watch?v=K35xG1buyFA)
First I wanted to make a metric clock but soon this idea evolved from a metric watch into an open course watch.

I knew that it would be hard (or impossible) to make the watch small enough to really wear, but I wanted to try it anyway.
This would be mostly a programming project, but that is nice for long, cold and dark winter nights. 

So my watch needs to be:
  • small enough to wear
  • easy to reprogram
  • capable of showing metric time
  • have selectable dails
  • have an easy understandable menu structure
  • controllable with just 2 buttons (digital watches with 4 buttons confuse me)
  • cheap (I'm still Dutch you know)

Someone who has a laser cutter could probably make a real nice case for the watch like the pi-bow acrylic cases.

or maybe a Venture Brothers watch case

I've just got myself a 3d-printer so I might come up with something nice :) Thanx for the ideas.
Cool. Cant wait to see the next version.

Wow COOL! You've got the temp. sensor working correctly! Really cool

I made some changes with your cod.

kenyer (author)  Eagle1993935 months ago

can you post the changes you've made?

There are some unnecessary lines of code. but how you can see it works. I use LM35 sensor, connect it to pin A0 on Arduino.

This is awesome. I didn't know someone had already come up with a concept of metric time. I was tossing that idea around years ago. You could make this into a pocketwatch and then you wouldn't have to worry about making is as small, or worry about the wrist band.

That is really a good idea! Thanx

This is epic! I have a similar project at github.com/rmd6502/arduino_watch - feel free to use anything from there if you find it useful. I think with a custom PCB and some really steady hands you can get this much smaller :-)
kenyer (author)  rmd65027 months ago
You made me really curious, but your link doesn't work. (steady hands might be the problem :) )

kenyer (author)  rmd65027 months ago
nice, thats a real smart-watch concept. Did you bring it further than the picture?

have you thought of making kits of this?
kenyer (author)  The nerdling7 months ago
No I didn't. All parts are easily obtainable so I don't think there would be much demand. For me this project was more a proof of concept.
ok

Nice project! Some ideas for your next watch: Use li-po batteries like ipod shuffle, good imitations replacement are cheap, add wireless charging and communication or via gold contacts, see garmin etrex gps units for example, embed fabric before casting like carbon fibre, cast in "natural" shape(not flat)
kenyer (author)  MartijnD7 months ago
great ideas for 2.0. The casting in shape will be hard though, because of gravity and the manufacturing of the mold.

Which Thermometer IC do you use ?

And one more question: is it possible to make your project using nokia 3310 display extracted from an old phone ?
kenyer (author)  kondzio291 year ago
Hi Kondzio,
I haven't tried it yet, but I think it should work with just a screen taken from an old Nokia. This is also just a screen soldered on a PCB.
kondzio291 year ago
isn't it nokia 3310 display?
you should make an arduino clone using the bare minimum of parts needed for atmel chip to work. think about it! when you finish the project and everything will be ok, you don't have to reprogram the arduino every time. i think you should make your own arduino clone using the dimensions of nokia display board. using that amount of wires can be a real problem. and another idea is to use 3.3V for arduino instead of 5V. you will only need 2 batteries and a small low drop-out regulator to power everything. also, you can try something like automatic light up the screen when you turn the wrist to watch what's the clock. this small improvement it's used by casio watches. cheers!

Cool ideas! I already made an Arduino-clone, but I won't be able to make it smaller than this one. I am waiting for my 3d-printer now to make a new housing for it. I like the idea of integrating a light-sensitive resistor and a tilt-sensor.
I should have used a 3.3V Arduino, but I didn't have one and this also works :)
Thank you for your ideas!

Cool project. You could use voltage dividers like here http://www.instructables.com/file/F4VCSBHGJQEJQFX
kenyer (author)  arnefl1 year ago
I know. They also exist in an IC format. The problem was that I din't have the parts (or the patience to wait for is) and I didn't have the room to put it.
The drawing is a really good explanation of the voltage divider.
