That stuff in the zeryon page about using a function generator to tune it, I have actually built a square wave oscillator before to do that, fully tunable. Except in my case it was for about 30-40kHz. I am not sure if my method will work with the lower frequency.
I also have a 12V Power supply too. I could probably tune the spedo myself with what I have on hand.
