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.

Require an Experienced RF Engineer to produce a detailed design for the following complete with AutoCad drawings, verifiable files for a RF software simulation tool, and gerber files/ component list etc. for PCB layout and manufacturing. Provide operational detailed narrative as well: 1) Provide a solution where a reference analog waveform within a certain bandwidth having a certain peak frequency can be sampled,digitized and compared with a desired analog waveform within a certain bandwidth having a certain peak frequency, which is also sampled and digitized. 2) Once both waveform frequencies are compared, if a match is found between reference input waveform frequency and desired input waveform frequency,the output will be a TTL logic 1. (provide option for inverted output to this TTL logic as well) 3) Once both waveform frequencies are compared, if NO match is found between reference input waveform frequency and desired input waveform frequency, the output will be a TTL logic 0.(provide option for inverted output to this TTL logic as well) 4) NO waveform peak frequencies outside the set reference waveform frequency should have influence on the operational logic TTL output. 5) Inputs to the system is continuous sine wave (CW) for reference peak frequency and standard RF signal envelope for desired peak frequency. 6) It is important that this solution compares the tuned and set waveform peak frequencies and not amplitude. 7) Both the reference waveform peak frequency and bandwidth and desired waveform peak frequency and bandwidth should to be adjustable/tunable/settable via laptop computer over USB connection and Ethernet. 8) System should accommodate adjustable/tunable waveform frequencies within 20MHz to 3GHz range. 9) Wave form peak frequency bandwidth should be adjustable/ settable to any bandwidth between 2MHz and 6.25 KHz. 9) Design should be verifiable on a RF software simulation tool. 10) Reference and desired RF input levels not greater than +30dBm.

Looking for someone who can improve an existing design or make a new design that can do more for consumers. Many wifi plugs and switches are on the market. I would like to design a light switch and an outlet that are truly smart. a plug and switch that responds to a human voice and can be programmed to follow on and off commands and be capable of loading customize-able response to commands. I would like it to be capable of recording electrical usage to report data to the consumer. The wemo is a similar devise, but i would like to improve greatly on their design. I would like the switch to be a flat lcd/glass/acrylic style touch screen so consumers can use their voice or hands. I would like to make a light switch 1 thru 4 gang capable of being a 2way to 4way switch. And a 2 plug outlet. These plugs and outlet shall be for interior installation not a plug into a plug like the wemo. the device must fit into standard us electrical boxes. I would like the design to be complete with a part list under 10$ a unit. I will be hiring a designer and a programmer to assist. Ck out link for Wemo breakdown. http://wiki.openwrt.org/toh/belkin/f7c027 also this is a similar design/style https://www.alibaba.com/product-detail/Euro-standard-wifi-touch-switch-220V_60359069387.html?spm=a2700.7906341.35.15.7s7uGW&s=p

I am interested in updating and adding to an existing medical device known as the NeuRx Diaphragmatic Pacing System (DPS). This system allows quadriplegics and persons with ALS to breathe independently of conventional mechanical ventilation. The DPS uses a fixed number of pulses per minute, which works well, but does not allow the user to experience fluid control over his or her speech pattern. My intent is to reengineer the electronic control box that regulates varying inputs and to incorporate a pressure sensor into it. This will allow the user to draw breaths as needed, rather than waiting for the next pulse. I am doing this for personal use only and have no plans or intent to bring thing to market.

I am looking for someone who is expert in electronics to build a device using Raspberry Pi or some singleboard computer to wirelessly control DSLR from an ipad . There are devices like these already in the market like www.cam-fi.comor http://camranger.com. I don't need the device to support all the cameras, whichever is easier to build it with. and I only need ability to see live view from the camera and trigger a click to take pictures and have them downloaded back to the ipad to view. Thank you

I have finished the design of a project with the help of Logisim (logic design simulator software) and I am looking for someone who can turn this design into an electronic design using multisim (Digital ICs and connections, to turn in later to PCB). Applicants must be familiar with Logisim, Multisim (Ultiboard experience is good too). Also good knowledge of English is required for easier communication. To get an idea about the project please check out the screenshots below: http://prnt.sc/bvwy5y http://prnt.sc/bvwyfk Deadline: End of August. For more info and for suggesting prices contact me (even if I am currently on vacation, I will do my best to instantly reply to anyone who is willing to get the job).
