    Looking for a circuit designer who can design a circuit that will switch to battery when voltage from solar cell drops below 2.5 volts. Additionally output power must not exceed 3.3v. Input battery voltage will not exceed 3.6v and input from the solar panel will not exceed 6.6 volts. The device that this will feed will normally draw 0.5 – 1.5 mA with regular spikes to 15 mA. Maximum draw is 20mA. The specs on ...

    Hello, I have found a circuit board drawing online that I'd like to have made into a virtual breadboard using the software at http://www.virtualbreadboard.com, free to download. The circuit drawing I found was probably made in paint, there is no author to it, and hence no support. The original circuit was made with three levels where the designer soldered IC chips on top of each other. I don't want to do this. I just want ...

    I need a small daughterboard designed. It is very basic. PCB Size +- 3x3 to 5 x 5 cm (3x3 will be best if you can make the terminals fit. Terminals need to be1/2cm x 1/2 cm. Center of the board, a 8 pin IC socket The board redirects the following pins to (looking from the top): - Pins 8 and 4 (top) - Pins 7, 6 and 2 (left) - Pins 1 and 5 to the (bottom) and - Pins 3 to ...

    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 ...
