My team has been working on a prototype using some off the shelf parts and its time to get it designed into a PCB. While we have a little EE experience, we figured it would be much easier to have someone else handle the PCB design. Basically right now we have a prototype built from a few off the shelf parts (sparkfun stuff mostly).
Our final product will basically be a stepper motor that is controlled via bluetooth LE. Right now we're using the following:
microcontroller+bluetooth LE device.
Motor driver, we're using this to drive the stepper motor (at about 1.7A, and 12V)
We're using this to read the battery charge, though I'm sure there's an easier way if we're designing our own PCB.
The last part that we don't have anything for yet is a built-in lipo charger. We need 12v, so we're looking at doing a 3 lipo cells. I've done some research and it looks like there's a bunch of battery management chips from maximintegrated that would do the job. They have schematics for completing things.
The board would charge through a DC jack. Lastly, we would probably have a few LED's controlled from the microcontroller.
Basically we're looking to combine all of this onto one board. If it makes it easier, the big easy driver board I believe is "creative commons" and has board designs you can download.
If this sounds like an interesting project, please apply and we can chat more.
