title: How to fund an open source project?
body: <p>As a thesis for my graduation I'm going to start an open source project: My idea is to port a complete set of mathematical libraries to Android, to perform numeric and symbolic operations, in the form of a programmable calculator like matlab or sage. </p>
  
  <p>I want to release this project under GPL, because I believe that ideas need to be free to work, but I also know that i will spend a lot of money to buy multiple device to do debug and fine tuning. </p>
  
  <p>I thought about selling the prepacked app on the market for 0.99, while giving the source to compile on the site for free. It would be like a small tax on laziness. </p>
  
  <p>What do you think? How do you think I could fund this project? </p>
