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. 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.

I need an expert, preferably with some experience of working with wifi switches. You have to design a wifi device that can control wifi switches, the switches are made by a third party, who would share some documentation with us. We already have an electronics expert with us, so you would not have to do any prototyping.

Hi, I have a web based business in the Electronics Engineering sector - especially in Embedded System area. We also have a flourishing online blog/e-mag with over 2 million page views per month. We are looking to partner with people for following:- 1. Technical Content Development 2. PCB Design of circuits to publish them online 3. Circuit Design - based on our inputs - to develop project kits and sell via E-commerce ( Your job is to design a proper working circuit - should be originally designed (not copied from elsewhere). We will be handling ecommerce part - you dont need to worry!) You dont need to quote any specific amount now. Just bid for job if you are the right candidate and has an interest. We will talk more via messages.

Need help designing a very small junction/mixer box to connect multiple communication devices into a single headset. Circuit Design / PCB Layout Testing / Troubleshooting Part Sourcing I'm based in Los Angeles, and would prefer someone local to Southern California if possible, as I may need to provide the devices for testing with. Hopefully this is a simple job for someone, and I might have more random widget jobs in the future. Please provide a time estimate for each task, and how soon you'd be able to work on it. - Research - Design - Testing See the attached to get a general idea of what I'm trying to do.

I’m working on creating a guitar pedal system that magnetically links together. A cross between a modular synth and a traditional set of guitar pedals. A base pedal that has various pedals that can snap on to the system. Instead of guitarists creating a mix-match board of various pedals and technologies (all with their own power supply and connecting cables mounted onto a separate board), they can connect together a set of pedals that all work and are designed to connect seamlessly together. A system that allows play and re-composing of order to create never-before-heard sounds. (Mainly analog with the occasional use of Midi for specific tasks like tempo setting.) Think little bits (, but for guitar pedals. Think Moog Sonic Six ( as an actual set of independent, connected components on the floor (without the keyboard of course). I need an expert in circuit design (that might also love the audio and synthesizer world). Any expertise in circuit printing, production and assembly would be useful too. Probably start with the core base pedal and then a couple pedals that will prove out the concept. Just a single prototype needed for testing with the goal of larger production based on the business side of things. I have write-ups and concepts for each component​ when we get to that point in discussion.
