That looks like an interesting discussion you all had a week ago. I wasn't even aware it was happening.

One tip I might add is that any copper track can be a test point if you scrape the resist off and solder a short length of wire-wrap wire to it that can then be grabbed by a scope probe. One caution: if you do it with a differential pair then make the wires slightly different in length so the probe tips are less likely to collide.

Concise reference material for the novice is a great resource. For those with experience it is that reminder, Oh yeah, I forgot about that. Nice compellation.

Hi Frank,

Great blog post! Your example plan-of-action/checklist table will hopefully get people into the habit of doing this, not just for testing, but for other aspects of their project, e.g. hitting go on the schematic, PCB, plan on what they solder first, etc. Often when working solo say on hobby projects maybe, it is easy to forget to create and run through checklists, even if it is a mental checklist for some of the milestones. By seeing the plan you've created shows the kind of detail involved for successful work.
