Hello All,
I just finished constructing, rather reconstructing (I bought it used from someone who had
-ahem- "interesting" soldering techniques) my first CGS module, a Gated Comparator. It's
running almost 100% correctly, and I spent a few hours last night playing with it - very
cool module.
The only problem I'm having involves the last 4 stages of the shift register. For stages 1-4,
the status of the preceding stage is moved along with each clock pulse, as it should, but
for stages 5-8, they also get moved along, but about 60% of the time, the wrong value is
passed (on instead of off, or vice versa). It's a rev 1.1 board with the RC delay between the
halves of the 4015. Any ideas as to why this might be happening?
Thanks, and looking forward to some more CGS modules down the line...
