    pick-ups

    Any insight into building this parts from scratch? Has anybody managed to build some like it was done for the igniters?
    Thanks

    After all an LM139 could be used to feed square pulses to the igniter transistors gates...

      Did you.manage to build pickups from scratch ?
      Beyond me such a quest but if you are electrickery minded ........
      Would you build all - the metal work etc too ?

      Most may say why do this ? Not.me as if you can
      and have the inclination go to it .....
      I am.all for making do and making oneself.

        No Jules, I haven't build it yet and as far as being "electrickery minded" I do not go much far beyond your average Arduino/ESP32 programming. Mine really was a [sort of] R.F.C. but I'm willing to go my way anyway. As for the building, yes, it will have to be made from scratch. So far this are the possible candidates: an Hall effect transistor for picking up the signal from the rotor tabs, another transistor for generating the square wave pulses [LM139] and [few] ancillary components. Next step is to rig something on a prototyping board and go from there.
        Thanks

          Hall effect sensor, only if it can be fed in tension by the same two wires which carry the signal; to be researched

            Or maybe something as simple as an induction coil? Mmh

                Thanks Cipher, I'll look onto them;
                in the case of an inductive coil, the shaping of the pulse, should than be in charge of the igniter's transistors, given the discreteness of the pulser coils package
                Will have to look at the reverse engineering job done in the igniter replica, on this board my member Bwringer[?] and se what kind of transistors are used there.

                  The fact that the bike exhibits a behaviour that can be matched to the coils reaction to prolonged heat, I.E. loss of efficiency and power, might hints we're headed to the right direction.

                    Antway I'm glad this post take some One entertained
