Places to promote OS Hardware funding

Fellow Hackers,

Does anyone know a place to promote Open Source hardware fund
raisers? There is a guy in the UK that is building a OSD (On Screen
Display) module, which can be used for RC Airplanes as well as other
uses. Since he's in the UK, he is using IndieGoGo to promote it since
he can collect money internationally:

He has a working board as seen here:

and here:

and has published all the open source files here:

What are good resources to use to get the word out and help him raise
his seed money?
