Hello Mr. My name is Leonardo and I'm Engineer. I''m very familiar with all microcontroller brands and families, but I prefer Microchip or Atmel. Also I already did projects to control using USB / Tablet. Please see my portfolio at: http://www.freelancer.com/u/carelle.html?page=portfolio For the prototype I can build one PCB using breadbord and my Galaxy 2 as the test tablet. Please feel free to ask what you need/want. Regards Leo

Hello I have extensive experience in this area. I have few questions: How the relay board communicate with phone? Do you have any Bluetooth or GSM chip installed on the board? Regards Zahab

Our corporation, Mercury, Inc., designs and produces custom PCB designs, ASIC's, Custom Firmware, and corresponding software(.NET, and Android). We can easily produce the result you are needing within the timeframe requested. We do have a few questions: What is the 1 variable speed selection controlling (or is it an input)? What is the 1 Momentary function controlling (or is it an input)? What version of Android is being targeted? (Not all versions and all tablets support a USB host) Is Bluetooth an option to increase hardware compatibility?

Hi, I am an experienced Electronics professional having industry experience in the Industrial automation, Consumer electronics areas. Have developed various products in the above domains and i am comfortable taking this project. I can source the relay module and tablet here thus speeding up and reducing time. Look forward for working on this. Quoting 15 days but can be finished faster on availability of the relay board readily.

I need only the relay board not the tablet (software will be programmed in android environment) or, at least, a board manual to simulate it, if possible.

Hello, I am an embedded systems designer and developer and have successfully designed and built an android tablet/phone controlled relay board controller but at present it is a 4 relay controller because have not used any micro controller in it. If you need a 16 relay controller, I can design that for you also. The main thing of interest for you is that it is controlled by the head phones jack of the tablet and not by the USB or charging port, so the USB or charging port is free to connect to the charger all the time. The cost of building is also very low as it will use a low cost non-USB micro controller. If interested then kindly contact. Regards, Ali Khurram @MAX Micro Systems
