Daisy-chaining 7 IC's

I'm not sure -- Kinda hard to check now since it's working fine. Like I said though, the PSU isn't even the same for the IC's anymore. Got two PSU's, one just for the LED's, and it's helped a lot.

I know how to solder, but what do I do to make connections on a stripboard? Using wires sounds "wrong" and so does making long solder bridges..
