Yeah, Jeremy this is really great. You can include the pictures of my Hall effect sensors in the post above in your instructable if you want to. The one with all the dimensions was taken before Philip Yao told me the type sensor that was used.
I'm planning to publish an instructables on the method I found to optimize troubleshooting charts in a few more days. I'll post the link here as soon as the pictures are compiled.
Update... I published the instructable sooner than expected... Improve a troubleshooting chartGreat job Jeremy! Hope to see lots more!
