That's a beautiful piece of work by your cousin, Zep.

Thanks. He had a much fancier version for himself. I wish I had some pics of it. His pad had hold down clamps for clusters. It sensed when continuity was broken on all igniters and it released the model. I believe his umbilical tower had some functions as well.

Good news. I've got it working again. The boards are laid out on my workbench and I'm not done with it yet, but it's getting there. I replaced all but one of the electrolytic caps. I needed a 22uF 35v but I only had some 16v and 25v. Got a few ordered, but in the mean time, it's working with that old cap.
I replaced a dead LED and the new one is WAY brighter than the rest. I'll replace them all while I'm at it. Good thing I got a bag of 100!

Got all the LED's replaced. The countdown timer is about 13% too fast. I've got it set at a minute and it takes about 52 seconds. It uses a 25k ohm variable trimmer resistor tied in with the 555 chip. I vaguely remember Eddie telling me that it ran slightly fast and was adjusted out as far as it would go. I don't know if it's a little faster now or if it's about the same as it has always been, considering it's been probably 10 years since I've used it.
I've learned a considerable amount about electronics making the repairs and I've got pretty good at soldering small components. The controller will be ready for July 20, but I don't know if I'll have a Saturn V ready to go. Woops, I see one of the LED mounting clips is pushed up. Fixed. Video http://sendvid.com/0a9hbjc0
