Dohickey is a client/server project for managing hardware information. Using built-in Ubuntu services to detect the hardware in your system it will make a request to the server for any available information about each piece of hardware. If something is not defined yet but you know what it is the client allows you to edit the information and send it back to the server. Each piece of hardware also has a compatibility rating, this is an average value of all rating values given by other users for this hardware, you can set your own rating for each piece of hardware which will also be sent back to the server for others to utilise.
