Baby Phone will be designed to look and feel like a traditional smart phone but built to be baby tough. All of this will be done utilizing as many off the shelf components as possible to make the project easily within reach of most home hackers.
The design of the project includes an interface (undecided) for customization of the display, a basic form of touch for baby to interact with the device, a full color display, battery charging (would like to offer wireless, but will see), and other feature you would expect within an advanced baby toy.
The overall goal is to have the project be repeatable for $30 USD or less.
Here is the cost breakdown so far:
- 4.3" Composite Display $15
- Parallax Propeller DIP package $8
- SD Card $2
- 5Mhz Crystal Oscillator needed to generate video signal
- 1.1k Ohm Resistor
- 560 Ohm Resistor
- 270 Ohm Resistor
That leaves $2 for the case, touch, and sound. Getting close to running out of fundage, but I still think it can be done.
**NOTE: The display price keeps going up and down between $13 and $18 so I settled on calling it $15 as you can seem to find it for that price on several different places (Ebay, Amazon, etc).
