		The air sampler is based on my Countdown Timer project, with some minor changes. I power it from a 15V DC adapter and the LM2940CTs are getting quite hot, especially when the fan is running. Putting heatsinks on the voltage regulators is a very good idea, unless you live in Canada.   Air Sampler v.1.0, 2009/05/05 Complete MPLab Project sampler.zip Assembly code only sampler.asm Precompiled HEX file sampler.HEX Click for higher resolution
