We need a simple and well-documented API to access an iPhone via USB and manage our device functions via mobile app. Our device PCB board is based around an FTDI USB-serial chip. On successful communication with device, the iOS mobile app will control the device's various assigned functionality through user inputs. Iphone access via USB should include: - detect connected iphone - connect / disconnect - read file (send-receive data to/from iphone via USB) Deliverables: 1. Complete and fully-functional working program in executable form along with complete source code 2. Installation package that will install the program (in ready-to-run condition) on the specified platform This phase of the project will only require microcontroller programming to establish successful communication. Please only apply if you have both iOS and FTDI programming experience. This is a 'pilot' base project and could be a long-term one.

We need a working prototype of an kitchen appliance. Professional candidate will start with a document describing how the appliance works and design a circuit, prepare a PCB layout and built the prototype. This prototype involves a infrared sensor, thermostat, fan and a hotplate. This product requires two inputs temperature in Fahrenheit or Celsius and distance in inches or millimeters. Based on input values of temperature and volume, output is varied. Output controls the speed of a fan and resistance to the hotplate. More details about the project are available after signing a confidentiality and non-compete agreement. There is room to pay a higher rate or longer hours if justified.

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 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.

We are developing the hardware structure of home automation system using ATmega328 based embedded system. We are going to interface Ethernet converter to ATmega328 microcontroller and thereby from the server itself we are going to controller the electrical loads. In the mean time, we are interfacing some analog inputs also. We need the person who knows arduino programming for our setup. So, we need your help to write the arduino codes for our project. We already made the hardware circuit design and we just need to upload the program.
