Soon after I joined the other day I was reading through earlier postings, not on any particular topic but to get an idea of what goes on. While looking through I came across one which had two small pictures of breakout board schematics at the bottom which I thought might be usefull so I copied them but iunfortunately did not record who, what, when or where I found it. The only information I have apart from the two pictures is that they both have opto-isolators, power supply (3.5volt or 3 to 5 volt in a wall plug) and the dates on the drawings 2005.09.10. My problem is that apart from not being able to find them again after searching through what seems like 1000s of posts and many hours my copied pictures are not as clear as I would like. The 'basic' one can just about be worked out as regards component numbers but the other which has motor control (?) on pins 1 and 2 cannot be deciphered.
Any pointers to where I can find the original posting would be gratefully received.
Thanks in advance.
