    Would like to make some simple modifications to an Epaper display extension board for a personal project. Simply want to remove some features - some power inputs and some buttons. Also, any changes to reduce the current required would be very much appreciated, though are not necessary. The changes can be seen in these 2 links: Link 1: https://drive.google.com/file/d/0B3eJSQ8x0YKhcU5rT256R0NTYTA/edit?usp=sharing Link 2: https://drive.google.com/file/d/0B3eJSQ8x0YKhekF1eW5SdzhudjA/edit?usp=sharing Details ...

    I am an Art student in Sydney, developing a lamp project. I have code which controls the glow of an LED using PWM over two minutes using an Arduino Uno. I need help in independently controlling two LED lighting strips, with the second operating at a 30-second delay. This can be achieved by code, or using specific hardware readily available in Australia/Online. This needs to be powered by a 230 volt wall socket, stepped down of course. Please find ...

    For the production version of our PCB design we do need a PCB designer to route a FPC and a 4-layer, dual side assembled PCB. BRD routing should be done in Eagle, as the existing layout is done also in eagle. Board size is approx 25 x 25 mm. You must be available for coommunication on skype as it must be interacted with the 3D CAD design. Estimated work laod is about 15 hours max. YOu should be able to ...

    Hi, We are trying to build a mobile device -which sends sensor data to database over GSM- for the first time. We are using SimCom Sim900R Dual band (900-1800 MHz) GSM module. We developed our circuitry on board using external GSM antenna, and now we want to build a compact design on PCB, which requires an embedded antenna solution. To do this, we have to find a solution for embedded Dual band GSM antenna. We can use small external Ceramic ...
