yes, i'm using a hall sensor with the RCM ignition, just delete the buffer IC needed for points. basically the same schematic as the one Rupurt linked to above. spark coils are from 3W ignitions or hand wound copies, info is from about post # 300 and on in the "scratchbuilt ignition" thread. this is the CDI published back in 1980 and not the one from '88 that tkg mentioned, would really like to see those schematics though.

don't know exactly which hall sensor i'm using but it's the type that needs two magnets, one to turn it on and one to turn it off. the reason i used this is because it can work at lower voltages than the ones used by CH and RCIGN and allows me to run the ignition from a single lipo cell.

and no, i've never had a telemaster
