Hey! Forum neophyte here, but I think this site is just what I needed. ^_^
Two quick questions. First, I need a part (preferably something smaller than an IC) that will delay a logic-up clock. I'm using a D flip-flop in a lights circuit, hooked up like this:
**broken link removed**
But when I put it together with the circuit, I'm having a few problems keeping it stable - turning on/off like it should with each cycle, and flickering on the down-clocks. I'm thinking that it has something to do with the sequence of edges when it's activated:
if D=L: CK↑ -> Q↓/Q'↑ -> D↑
All as fast as the chip can register and output each one, which falls into the region of single-digit nanoseconds, where I think the chip gets confused about what's an input, rather than just a blip. So here's what I'm looking for, in order to give the D change the time it needs to stay stable for the clock.

I was thinking something like a capacitor, but I'm still not exactly clear on how it would work in this situation, so I couldn't say. Anything that comes to mind that would work for this application?
(If there's another reason the flickering/etc could be happening that I'm not thinking of, let me know. Here's the schematic
**broken link removed**
Also, the pins for jumpers on PC boards and such, the ones that stick straight out of the board - anyone know where I can get those? (I'm assuming Digi-Key or Mouser, but I have no idea what they'd be called. >_<)
