PCB 12 and 3.7v switch, stepper control, Android USB controlled.
Closed - This job posting has been filled and work has been completed.
Inputs are 14v wall adapter; on-board accelerometer, on-board temp, pressure, gyro, humidity, Android commands via USB
Outputs < 2 amp charging for 12v batt;
3.7 and 6v to equipment;
4to5v stepper motor control 2 NEMA 16 in parallel;
intermittent LED lighting;
on-board accelerometer, temp; pressure, gyro, humidity values to memory, then to Android via USB.
Board will communicate with Android USB using the Linux IOCTL.
TI's SensorTag has many of this board's needed sensor elements on their one device:
(SensorTag summery may be seen at:)
Board Size: 65mm x 130mm.
Size constraint for components footprint on-center of board: 55mm X 120mm X 8mm
Additional capability will be needed after this first-phase project is sent for fabrication and test.
One such capability would add processing of 2 wired-in cameras and microphones into pic and video files then handed off to the Android.
Another may be to add a receiver section for short range low power 4.0 BT.
The board may need some storage to accumulate its data files until Android is able to accept up to 1 minute later.
This phase job completion will successfully run on simulation software common to the board shops here in the USA.
This is the first of many jobs we will need to generate and refine over a multi-year period. I am seeking a single long term working relationship with one design engineer.
Payouts: Due to the nature of a new long-distance multi-jurisdictional contracted relationship, for this phase of the project and relationship please define 4 logical milestone tangible deliverables, each earning equal payouts.
