Logitech G25/G27 shifter/pedals adapter case
The idea behind this project is to create open and inexpensive USB HID adapter for Logitech G25 / G27 pedals and shifters based on affordable components. Once you bought (or built) your new shiny and awesome direct drive steering wheel you no longer need your old but still working Logitech wheel. But its parts still can be used as standalone device.
