    I am looking for an experienced PCB layout professional to design a PCB shield for a Arduino Mega Pro (https://www.sparkfun.com/products/11007) The goal of this project is to create a intermediate step between a proto-shield and a manufacturing ready version of my specific application. As such, the design is relatively straight forward using through hole solder points instead of surface mounted components. For someone experienced in PCB design and familiar with the arduino platform, I believe ...

    I want to develop a hand held product than can will harvest solar energy and kinetic energy into rechargeable batteries. After which users can use the device to charge their portable devices. The product will be very small: 70mm Length by 20mm width by 12mm height I will be collecting solar energy via a solar cell measuring 60mm x 20mm. For the solar power part of the device, I wanted to design something that works like this below: http://www ...

    Design replacement power circuit in Solid-Run Cubox for Power Over Ethernet. Have current PCB design (attached) and would like to replace new design to bypass external 5V DC-In sourcing power from 802.3af POE. I would like to use a MAX5974A or PM8800 to achieve this, but size of the final board is more important.

    Im loooking for an experience CFD Engineer to perform a CFD analysis of a small cooling device im creating on 3D. The device is using the airflow for cooling. Its cooling capacity should be investigated, and having that in mind, the motor power/ fan size should be adopted. You should have in mind the common temperature range of the units to be cooled, and preferred temperature range to be achieved. You will also need to investigate the electricity consumption,the ...
