Fellowships of smaller amount to support your main postdoctoral fellowship I've a certain postdoctoral scholarship for a year in certain area of applied science. But the scholarship is not very generous compared to the local cost of living (think of Marie Curie postdoctoral fellowship as something very generous for any place), so I'm planning to apply for a scholarship which I'm okay with being relatively smaller amount (as much as € 500/month or $ 700/month is good enough, more is of course better :), which I can earn as my 'research expenses' scholarship, or some such similar.

Do you know of any such examples of such a scholarship? If yes, could you please be kind enough to mention them?
Two obvious possibilities come to mind: 


travel grants (there is plenty of variations, including e.g. small travel grants provided by the grant agencies and grants for attending a particular conference given by the conference organizers) 
intramural grants (this is strongly institution-dependent, of course).
