The biggest problem is the $70.00. I received two grants for my project, both of which are almost tapped out (I have just enough left to reimburse the machinist for the materials he used in building my enclosure). The state school system is frozen right now so no money can be spent AT ALL, not even for office supplies!

As I said before, this entire project has been built on a shoestring budget, meaning instead of buying a specialty chip, I often had to go the long way around and build it myself.
