I would like to create a circuit that controls 2 muscle stimulating electrode pairs with an arduino UNO micro-controller. Attached is the current circuit which works well for the stimulating electrodes, however there are a few changes I would like to implement to this configuration: - I would like to be able to adapt this circuit so I can control their on/off state using the arduino. This includes precise timing of when the electrode's become active and the duration for which they remain in the 'on' state. - I would like to be able to keep the integrated intensity control If this is a job you would like to take on, please do not hesitate to contact me and I will be happy to discuss details, any queries you may have and provide a full request for quotation. Kind regards, William Markiewicz

I have a Bluetooth 4.0 micro controller with inputs and sensors that when connected I need converted to midi values. Basically a plug and play midi keyboard but with Bluetooth. Latency is priority being its a musical instrument. Newer MacBooks have a native Bluetooth to midi I want to utilize but also needs to have a BLE dongle for other users. Would like it to run on OS X to start and possibly windows if the price is right.

Need to develop a GPS tracker, Engine Shut Off, and Passenger Weight Checking device for CNG cars. This device will be outfitted onto CNG cars and will transmit the data through GPRS GSM sim to a central server. The central server can send out requests to shut off the engine. If weight checker is not possible, we need a switch for the driver to indicate his ability. Switch up for available, switch down for not available. Each device should cost under $40 USD to produce. The device can be built with micro controller parts found around electronics stores. The server side aspect can be done by us but if you have experience developing software as well, that is a plus. The software for the micro controller will have to be developed by you. Please provide past work examples, your experience, and how you intend to build such a device. Include the code "343" in your response so I know you read the description. Very important that all these parts can be sourced in Bangladesh or...

I am currently doing a project on MBED LPC1768 to read a ECG wave and display its properties on a C12832 lcd. I need the program to read the ECG signal and display a clear signal. I need to be able to read the waves and display its properties simultaneously as the waves run. I already have a base program so you can work on it to improve the program to meet the required criteria. price is negotiable.

I have a programmable infrared TV remote control that that I need to clone the PCB. I'm needing the full schematic, Gerber files and other necessary files to recreate this board. This remote control uses a removable but programmable micro-controller. It's a PIC16F648A that sits inside of a socket (16F648). It contains two Infrared LEDs, a 9A104G resistor, a 10v capacitor, 4.000MHz Crystal and several very tiny resistors on the other side. This remote is powered by 4 AAA batteries. This PCB board is about 2" wide and about 8" long. Also a primer on the circuit and how it works would be great! Also, I have pictures of the PCB that I can provide.

This is phase 1 of the project. Writing VHDL code to convert 12 K hz to 40 K hz HS video signals to standard VGA video signals using a FPGA and external RAM for screen display. Input signals will be digitized for the FPGA from a Analog AD9880-KSTZ-150, On screen display ( OSD)and input processed by a STC12LE5624AD micro controller. Input signals to be converted are STYLE (RGB(A), RGB(D), SOG, YUV, RGBS, RGBHV and YPbPr). OSD control will have Horz. position, width, Vert. position, height, phase, sync ( separate HV, composite HV, SOG and YUV. Resistance setting (75 ohm, 750 ohm) Scanning (progressive, interlaced).Screen resolution ( 640 X 480 and 800X600). Also in the OSD window it will show in real time the VS and HS input frequency. THE OSD function will display on default when no signal is present and have a time out to close when not being used. We will supply a prototype board for testing the VHDL code via a JTAG interface. And will provide a schematic of the prototype.(ID: 74...

Hello ? We have a two phase project that requires an expert with a M2M device control over satellite experience/ background to design a detailed schematic to turn on/off existing simple piece of hardware (self-powered) as needed over a satellite constellation from a work station computer. This detailed schematic will need to show the end-to-end M2M solution and detailed diagrams of all components and their interaction. We will provide the simple schematic of the device that needs to be controlled/"power on/off" through an accessible wiring harness and/or inline power switch or micro-controller over and existing satellite constellation (Iridium/Inmarsat). The device is self-powered and has an existing tri-band antenna. (Avionics/Aerospace engineering background helpful but not necessary) Phase two is to build the prototype(s) and merge with said devices which can be used to demo to Avionics/Aerospace team on a desktop version or over Iridium SDK . We are receptive to h...

I need a resource that has experience with ESP-12 (8266). I want you to get this device to interact with a color touch screen without utilizing an additional micro controller. I would like the touch screen to be 4" to 5" in size. You can use SPI, I2C or what ever GPIO pins you need that are available on the ESP8266.

Design hardware, Schematic Capture, and PCB Layout. We're developing a low power Micro-controller solution that can fine control small DC or Stepper motors using potentiometer as feedback. The motors are confined to a 270 degree rotation limit. A shiftless potentiometer is integrated with the motor to return position-feedback. The device has a 9v input. The primary areas of development are, power hardware/management, motor control/driver. Consideration for noise, power are primary concerns. If you are able to do the software as well, that's a huge plus. But the primary scope of this project is the hardware design and development.

In order to validate the functionality of all components of my circuit, I am looking for a circuit and PCB designer which can do the circuit refine, design and prepare the PCB boards. To give you a general overview of the circuit: it is basically the whole supply of the circuit which consist of a solar-cell charger and a 9V battery which must provide us a 3.3V output for the micro-controller, a 5 V and 100mA to drive a solenoid and a 5V and 500 mA for a USB charger. I have used 3 ICs made by Linear Technology, which I can provide you with all their datasheets and information if it is needed. Regards, Sanaz Haddadian

Update: After a long discussion with my insurance agent, I've removed the design insurance requirement. I am looking for a electronics design partner to create two printed circuit boards for a robotic lawnmower. I am price conscious and interested to learn about any price trade-offs that are available. I believe I want two boards as follows: The base station should contain a PCB that is AC powered using an external transformer. It should have basic location capabilities, an RF transmitter, a modulated infrared light, and provide power to charge the robot unit. The robot should contain a PCB that is battery powered. It should contain a micro-controller, multiple motor drivers, battery management, GPS capabilities, an RF transceiver, and infrared sensors, a small LCD touch screen, sound generation, and several sensors including one or more cameras. These boards should be in compliance with relevant US and EU regulations and standards. You should produce basic software for the sy...
