Official Mission Pinpossible Discussion

This was a really cool challenge. I’ve always wanted to get into hardware hacking, but never had the opportunity to do so. I feel like this was a decent crash course.

However, I keep noticing what look to me like discrepancies in the bit stream that don’t match everything I’ve been reading about the protocol. Has anyone else noticed these? I just can’t figure them out. I’ve already completed the challenge, but it’s driving me kind of nuts not understanding these small details.
