Create a schematic and PCB design (include layout, BRD, and BOM library files) for a multi-chamber ultrasonic piezoelectric atomizer controlled by an particle photon microcontroller. The system is comprised of 5 separate chambers, filled with a fluid, at the bottom of the chamber is a ultrasonic vibrating mesh atomizing disc that is actuated by a ring piezoelectric. There is one atomizing disc per chamber. At the end of the chambers there is a fan that pushes the atomized fluid into the air. The fan is to be controlled by PWM on the photon microcontroller. Each piezoelectric disc is to be controlled by the photon particle microcontroller. https://www.particle.io/products/hardware/photon-wifi-dev-kit Please either use the p1 or photon breadboard in your designs. For control, each individual piezoelectric disc should be able to turn on and off within 1 second. LED indicators for status of the atomizer shall be implemented, along with micro-usb connectors, power, and reset switches. Piezoelectric Driver KS-W16-142K is currently being used. Please see attached datasheet for details. Photograph of current piezoelectric driver which only supports one piezoelectric drive is attached. Major components on current driver board.

Hey guys, I am looking for an experienced hardware engineer who already build smartwatches. We are still in the phase of designing the product, but moving closer to building the first MVP and prototypes. There are several fields you should already be familiar with, like: - OLED displays - Wifi & BLE - external sensors added via I2C - Android / Linux wearable OS - best would be also microphone technology A rough roadmap would be: - decide on platform (Android or Linux) - build first prototype - iterate until we can go into series production You will work with a passionate team of designers, hardware engineers and software engineers. At the moment it is not defined how long this project will run. But anything from 1 month to full contract is possible since we will build a consumer product. I am very happy to hear from you! Cheers, Philip

We have an Arduino controllong a complex mechanical system consisting of pumps, relays, stepper motors which takes input from a serial connection and multiple analog inputs. You are an experienced Arduino developer who is able to help us refactor this code we developed during our r&d phase into production ready code, and preferably would be able to help us port to raspberry pi. To help us weed out spam applications please include in the body of your application your favorite Arduino model or function and why as well as a link to your GitHub account

We are developing a robotic equipment based on Bekhoff PLC modules, consisting of sensors, motors, valves. We need to make changes to the existing TwinCat code to integrate new functionality in the equipment. An external WPF application also communicates with TwinCat and might need changes too.
