6. In retrospective… • Joy of programming just for myself, I felt like little kid again. • Like coding for the first time, did not notice time passing • Old habits die hard, Objects vs. simple data structures • I’ve done other hobby projects, but…
7. Summary • Raspberry Pi is fun to hack with and easy on the wallet too J • Simple is beautiful and can be a lot of fun • https://bitbucket.org/bitodi/spacemonsters • https://www.meetup.com/Helsinki-Gophers/ • https://astro-pi.org/ • https://github.com/nathany/bobblehat
