Hello, I am working on a new type of interactive toy that records 5-10 seconds of audio (ex. human speech) and then sings the recorded back in a variety of musical styles (rap, jazz. etc.). The toy must also be able to add random words and phrases to the pre-recorded text, such as "cool", "I love it", etc. Previous experience in circuit design, software & hardware to record and process sound is required. Contact me for more details.

Someone who understands electronics enough to design circuit and schematic capture. I will need someone to transfer my schematic from a pdf to Altium or EagleCAD. I do not have time to do it myself. Job will require you to not only to draw schematic in a pcb software, but also create footprint of components that are not already in an existing library and detect any errors. Skills needed are knowledge of circuit design, layout design, and electronics in general. I will have schematic, BOM, and datasheets for completion of job. Additional key words: STM32, component selection, power and signal integrity, embedded hardware, firmware, integrated circuit, Lipo battery management IC, battery charging IC, IMU, wifi module, motor controller, video processing. The perfect candidate can easily transcribe schematic over to pcb design software and layout according to datasheet recommendations, but also suggest ways to reduce BOM, reduce PCB real estate, suggest components that may work better, etc. I need a team player who can stick around until prototype comes to life.

The project is to develop a layout for Arduino Nano shield with the mentioned specifications. This job will require you to design an Arduino Nano shield, which will have RJ25 connections as a mode to connect the sensors. The shield should also have built in motor drives so that it can drive 4 DC motors and 2-4 servos. The shield should be made in such a way that it is compatible with most of the off the shelf digital and analog sensors (Arduino sensors). The shield should also have TX/RX as well as TCP/IP connections to support wireless connectivity. Finally this entire shield should be designed keeping mass manufacturing in mind. If you are interested for this job please apply first and then we can share a Product Specification Sheet with you which lists out the exact requirements.

We are interested in designing & prototyping a compact embedded system which will comprise of a small hardware unit with the following tasks: 1. a device comes with a button. 2. The device also includes a bluetooth LE chip and a small motor. 3. When the button is pressed on the device it will start the internal Bluetooth device scanning and look for the nearby BLE devices (iphone or android devices) and if matched device found it will rotate the motor by 90 degree. Please provide an abstract hardware cost estimation (prototype/mass production). Please provide further information on the design process you are familiar with (PCB design software, microcontroller of choice, design process, prototyping, testing, etc). An estimation of project delivery time is also required. Thanks

Need an engineer to write the C code in Keil uVision 5 which will be uploaded to CY7C68013A via Cypress SuiteUSB 3.4 - USB Development tools for Visual Studio on the USB port. The code should compile in Keil uVision 5 without any errors so that the .hex is generated which will be used by the Cypress SuiteUSB. I have been able to run a basic code which toggles an IO pin via this method. The C code I require should use the External Bus of CY7C68013A which is available only on the 128 pin variant. The code be capable of sending and receiving data from the 8 bit data bus for a given 16 bit address on the address bus within the specified range of addresses meant for accessing external data.

We need a hardware, electronics or mechatronics engineer to help with the hardware development of a prototype currently on the DragonBoard410C. Essentially the dragonboard will run android and the freelancer will need to integrate a 3 axle accelerometer, a 10htz gps module and other 3g Comms components onto it. Then the data from these sensors should be fed into an app in android that runs on the board.

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.
