Ok, here is a couple of the Knight Rider circuits. The jpg diagram was from the internet and I have it marked as 'Works' with no notes or scratch outs on the original print out I have. I have not tried this one again yet.
The TinyCad and pdf file I also had marked as working. This also originated on the internet, but I can't find the original file of it? Anyway, I couldn't get the original to work and changed a few things. This was also a couple years ago and unfortunately any memories of what was changed have faded. The notes are not mine, they were on the original diagram I had, but can't find now.
The bad news is I tried this one last night and so far it is not working. Will fiddle with it more today. I probably have something mis-wired, missing jumper or something? I will report back if I get it fixed and post a new diagram if there are any changes. Or will be back asking GRJ and stan2004 for more assistance.
