Contributions are completely and totally voluntary. I basically use them for materials for prototypes and equipment for testing. I've probably received approx. $450 to date. And every cent is greatly appreciated.
BTW, if you use snail mail, please be sure to include your online "handle." A couple of times I've recieved an envelope with some cash and a first and last name that don't ring any bells.
You can also find a "Donate" link at the mothership (http://www.jpthien.com).
