Rpm meter / Tachometer for LML SELECT II

[Ilango]

Hello folks. 

This is about a small project of swapping the speedometer watch of my lml-select with an rpm meter. The watch inside the meter console was a simple wrist watch neatly tucked into the meter assembly. And replacing its battery was a cumbersome process. Hence I decided to do this conversion. 

Ripped apart the speedometer assembly, made a few holes to mount the rpm meter dial. There wasn't enough space to mount the rpm meter as one unit. So I split the circuit board and enclosed it in a waterproof Sealant mould. Since I took the rpm signal from the cdi high voltage input side, I had to recalibrate the rpm meter to display one-third of the signal frequency. 

Pictures and a video have been attached.
