Can I build a basic smartwatch with the digispark?
« on: May 12, 2014, 09:10:04 am »
Hi Everyone,

I backed the digispark kickstarter campaign in 2012 and received 3 digisparks.
Since then I have messed around a tiny bit with arduino, but basically I am a total novice.
I have been keeping my digispark for the right project. But I need your help.

Can I build a rudimentary smartwatch with the digispark as the main board?
I want to use a 128x128 oled display. I have some nice little 300mAh li-ion batteries.
Obviously I would need to incorporate a bluetooth module as well.
I think I would like to use a vibration motor, and have no speaker/no sounds.

What do I want this watch to do?
Not much! I want to limit the watch to timekeeping/organisational functions such as:
sync with google calander.... sync with ical...  so that it can not only tell the time... but also alert me when I set a reminder with Siri, or alert me to my google cal/iCal appointments.

I have a 3d printer to make up the case (I work in a product design studio), but I don't really know where to start with the list of components, and especially the coding.

Can the digispark do this? or will I need something more powerful?
What software would I need to run to have a simple but appealing interface?
How would I go about designing the interface? (I would be quite particular about the interface).

Any feedback would be awesome.

Thanks guys.

Ross

Well, you can probably find a display module and a Bluetooth module that speaks I2C or SPI, and use those to talk to the Digispark...getting any decent interface and functionality coded up in the 6KB of flash on the Digispark will be a real challenge though.

Thanks for the reply.
That's a good point. I recently saw this on kickstarter... any thoughts?
