But, the "Kit" or rather PC board that Ken offered is using a chip that takes the "Z" non-linear curve of the regular O2 sensor and makes gives it a more linear response by using a logarithmic chip to drive LEDs rather than the frequently used "linear" LM3904 chip. Ken's design does not use the expensive Broad Band O2 sensor just the regular O2 sensor. He estimates the parts for his design would run around $20 (not counting the O2 sensor) plus around $10 or so for the PC board (which is the only thing he has indicated at this time he was planning on selling).
