MAGNETO TIMING LIGHT Plans

I am looking for plans to build a Mag timing light with the buzzer that
changes pitch. I remember seeing plans in a Magazine. Maybe Sport Aviation.

But since they are relatively cheap ($70), why build one? (unless you have
lots of time on your hands, are handy...)

Nothing there that I saw...

Requires no batteries or buzzer or lights:

This is quoted in the link above. No reference to where the schematic is
located though:
