Bob,
I had the opportunity to put a scope on the circuit this past weekend. I sent a photo of the screen (jpg) file to your AeroElectric email address, because sending attachments to the Matronics list doesn't work. But I don't know if your email accepts attachments either. I can put the photo up on a website if necessary, let me know.
When the motor is running, the collector of Q103 sees 5V. When the limit current is reached, the voltage at the gate of Q114 drops in about 200ms.

Yes, I saw your picture. I thought I had replied
and thanked you for the effort. In any case, you've
validated the paper-work that went into the design.
How do you plan to package the accessory? Others
on the List might find value in seeing how it
goes together.

Great! I hadn't gotten a response (I'll have to check my junk filter) so I just wanted to be sure the picture hadn't disappeared into the ether. Murphy's Law has not yet been repealed.
The components were assembled on a Radio Shack circuit board. I bought a Radio Shack Project Box to put it in, thinking (foolishly, as it turns out) that the board would fit their box. I had to chop the board down to fit, so my previously nice and neat circuit board now looks rather ugly, but it still works. I will put some pictures up on a website in the near future showing what I did.

Here are pictures of my IVO circuit. I soldered the parts to the 'wrong' side of the board so that I didn't have to worry about unintended connections on the back side. The board looked very nice before I had to chop it down to fit in the project box. I've also attached a PDF showing Bob's circuit design and the physical arrangement of parts and connections I developed. I should have gotten the project box up front, and I could have easily placed the components closer on the board. Oh well.
