Hi All,
A buddy is interested in some help making his own controls for a small jet engine. While the one he'll be using is normally for RC planes, he plans to put it on an RC boat. I'd like to ask if anyone's had any experience interfacing high temperature sensors and high speed rotary sensors. He told me he doesn't need fast measuring, roughly taking a measurement once a second should suffice, so I thought the PICAXE might work.
Here are the gating items as I see them at the moment. I'm waiting on more info from by buddy on specifics, but these were the things he mentioned that concerned me immediately.
High temperature sensor - up to 800 degrees C. A quick bit of research turned up a K thermocouple and a PICAXE link to reading a thermocouple here. So I might have lucked out here.
High speed rotary sensor - something capable of measuring up to 150000 (150k) RPM. In a perfect world, I think a sensor that could output either serial data or an analog voltage would be great so the PICAXE doesn't have to attempt to read 2500 pulses per second, however, I don't know if a) such a sensor exists or b) if the PICAXE is indeed capable of counting that many pulses in such a short time. Would a hall effect sensor with a PICAXE perform such a feat?
Any suggestions or words of wisdom are welcome.
