Been a bit slack on the project side due to xmas but heres a look at the Hall effect sensor working on my little scope ..
I can get a positive or negative going pulse depending which way around the Hall sensor you point at the magnet ,closer you get the larger the pulse what you see on my scope is about half it could do ,need space due to drum wobble ...Sorry using old camera today lcd screen dead so not sure what the photos like till i put it on the pc .
I am not sure what my circuits need or if it matters i recall Doms post on hes first go at the 4046 pll and it needed a pulse going the right way for it .
I am going to try this for the syncing of the large drum and another with fewer magnets for the small drum..
