I would like to share this cheap DIY inductive pickup design and prototype. Buying a commercial inductive pickup is not cheap and sometimes it may not serve the purpose because you can't use it with your normal frequency meter due to incorrect reading or low pickup signal. I have demonstrated to design an inductive pickup that will surely pickup the signal and able to read with an ordinary multimeter with frequency counter in Hz. Why build if you can buy a commercial inductive pickup? Why build if you can buy a cheap tachometer with inductive wire? I would like to hear your view why? Now I have the flexibility and knowledge to build further project that can benefits everyone. On my future project, I would like to design and active battery powered inductive pickup with spark indicator, another one with built-in RPM meter on an Arduino based micro-controller, also another one which you can connect it to your mobile phone. The possibility are endless. I hope you will find this project useful and build for your own.
