PCB Hardware Assembly for Device
Budget: $200 – $400 USD
Design and print a functional hardware (will reimburse for the hardware and PCBs if it works) that will have the following tools and capability in a single system:
1) Should be able to put inside glass full of water.
2) An array of 5 piezo actuators (prefarably ceramic or polymer) embedded to a single flex pcb. Four square and one cicular disc actuators should have a single particular ultrasonic resonant frequency and have a single driver board with power consumption of 1.5W or less. The piezo will atomize the water. So you have to design the driver (transformer or other elements) accordingly.
3) A sensor should also be added (to the flex pcb along with actuators) to sense the water level and send wireless signal to its monitoring module outside.
4) Embedded programming language (scripts to change parameters for sensing and actuating).
Please note:
1) I will pay for the hardwares of the design after it works. So it is not part of the compensation package. It's from my pocket.
2) Send me your portfolio of similar hardware design work that you did.
3) Will be NDA.
