It looks like I will be flying back to Sydney on Saturday after a days flying, working on testing hardware and software. Sounds like a fun day, but I expect it will be a long day. Just like today actually…

Programming and debugging are going well… I was searching for a problem and after about an hour I found a comment saying “Outputs will mysteriously turn on if this is not correctly set… This took me four hours to find”. It has now taken me five hours with this same problem. Time to comment more code.

Anyway I need to get going. I have to do some more programming and testing. I now need to test a buzzer…
