I did try your idea by the way your right was better! But yeah for the sake of it for this little circuit just pulling it back to a chip :)

Yeah just had a play about with it I think for this sequencer I'm going to go no flip flop at all. Adding 1 flip flop solves half of the problem and yeah it just takes the circuit to more complicated where I wanted to get something reasonably simple formthe video so I'm going for just the 595 chip and dealing with the quirks

Indeed; that's how I was doing but I just got impatient on that 1 hole and paid with a big bleeding crack haha. But yeah quick and light melt through the bugger

The FF output goes back to zero at every rising edge of the clock because the D input is tied low.
Independently of that issue, with both circuits, a problem remains, especially with a fast clock, if you hold the button down longer than one clock cycle, you get multiple bits clocked into the shift register. You would probably need to use a second FF to fix that problem.

I saw that you damaged the plexiglass housing while drilling. I worked for a while at a company that made advertising panels (in plexiglass). We used blunt drills to drill holes. The drill does not cut into the plexiglass, but melts it locally and scoops the material out. I hope this tip helps you with future projects.

aah yeah it does doesnt it. ill give your idea a go so just to clarify, Clear to ground, D to ground, Set button the button. i cant get back onto the chat wha did you say was resetting it again i cant remember. thanks antoine

I just thought of a case where the circuit that I suggested during the live stream today would work better than what you implemented. With a slow clock, if you press and release the button while the clock is high, with what you implemented, the FF's output will go high while you press, then go back low as soon as you release the button, before the bit can be clocked into the shift register. With what I suggested (tying the FF's D and clear inputs to ground) , the FF's output only goes low on the next rising edge of the clock, at the same time as the bit is clocked into the shift register.
