As awesome as that would be, I just don't have that much money to drop on a project at the moment.
Also, here's a quick question: I'm trying to build an intervalometer (timed trigger for time lapse photography) using a 555 timer. the schematic I'm going off of calls for an NE555 timer. What I can pick up in town are the TLC555 and LM555 chips. Looking at the spec sheets I can't tell a significant difference between them, but I'm not sure. Are there any significant differences between chip numbers I should be aware of? or are they just different numbers between manufacturers?
