gunrunnerjohn posted:Adrian, your "high end" is only for a select few, most folks won't go that far. I'm thinking of a tool that's perhaps more expensive than the $10 version, but parts would certainly be no more than around $20. However, you make a good point, we may need to re-think the comparator speed, that will run the cost up somewhat, but not out of reason.
I like a medium solution also. Here's a comparator that would work well for this that I looked at. I didn't want to deal with making a PCB though.
