If it helps anyone I also built that noise drum - and agree that it’s more suited for a hi-hat than a snare. I redrew the layout to include a 10 pin power connector and positioned the jacks/pot to be easy to put on headers.
It was one of the first stripboard layouts I did so could probably be improved but if you want one with the 10 pin connector without redrawing it yourself I can confirm it works. More details in my git where I also have the diylc file and a pdf of the layout: https://github.com/jhitesma/Modular-Synth-Build/tree/main/noise_drum
I actually built two of them on the same board with one mirrored - mostly due to a happy accident learning how to build stripboard
And a week or two ago I repaneled it and added vactrols across the delay which opens up a lot more possiblities.
