The InfraRed Remote Project: Revisited for the third time!

In 2008 I started a project, and I never finished it for those who visit this site. I had a working project, but never did good documentation. I have finally pulled through with the final product! In this post you should be able to find: both schematics, both programs, and some pictures. What you won’t find is the circuit boards. I made them using the old fashioned way with Ferric Chloride and some Radidio* Shack press on etching strips. (*intentional misspelling)
