    I need a device which is able to gather data from an accelerometer and a RFID reader. It should only activate when moving. If it moves, it should start transmitting a data stream, including the data from the accelerometer and the RFID reader via bluetooth to a connected bluetooth device. Thus I need the device to contain the following components: - Bluetooth Module - Accelerometer - RFID - Battery (needs charge indicator) The device should be able to read data from RFID-Sources within a ...

    Currently, I have a prototype product that runs off an Arduino Uno, which controls two solenoids and 2 Mosfets. There are 2 analog potentiometer inputs, a push button, a microswitch and an LCD display. The prototype functions flawlessly and performs exactly how I want it, however, I want to add wireless communication (BT or WiFi) with an Android Device. Then have the Android device perform the functions of the 2 Pots and the push button as well as display the ...

    I have created the schematic for a project that I am working on, but because I don't have a professional PCB layout software package I cannot build a board big enough. I have created the schematics in EAGLE and the basic layout of the board, I need someone add the additional components on a larger circuit board than I can create with hobbyist software. Prefer no more than 4 layer PCB, 2 layer if possible. Components on one side ...

    I need to find a technical person to write articles about various topics related to the printed circuit board industry. Could you write a unique article about how a PCB designer can improve yields when designing their printed circuit board? How about 5 mistakes PCB designers make when designing their boards? Topics will include flex, rigid, rigid-flex, PCB design, and assembly/contract manufacturing.

    Eagle PCB board layout expert needed for prototype. The schematic is complete; I need someone to layout and route the components. It's a small board and the dimensions must not change. There are also three connectors that cannot be moved from their current position. Screen grab of board layout with highlighted components that cannot be moved is attached. Eagle schematic and board provided. Thanks in advance for your interest.
