Thanks to everyone who wished me a happy birthday.
No supper exciting news to report. I went hiking today. Other than that I've been adding some shelves and better lighting to my laboratory in the basement. Also been spending time on my next project. It's a quadcopter, which is a 4 motor helicopter. Besides designing the frame structure I also need to write a control system since the design isn't naturally stable like an airplane. Fun stuff, but it's a big project.
