• 1500F(800C) 1M K temperature probe

  Jan Zumwalt • 03/31/2016 at 09:50 • 0 comments

  Aliexpress has $2-3 K Type Nylon Braided 800C 6mm Screw Thermocouple Temperature Sensor 1M 3.3Ft. The other option was 2M ohm, but the selection was poor.

  Application:

  4 CHT, 4 EGT

• Expanded External Analog IO

  Jan Zumwalt • 03/31/2016 at 09:29 • 0 comments

  Because this project will require considerably more IO ports that any micro-controller can provide, I identified the best IO expansion candidate as the MCP3008. It is a $4 16pin dip ADC with 8ch@10bits over SPI interface. Since SPI can be daisy chained and only requires 4 IO pins, perhaps 2 of them will serve all the analog interface needs.

  Application

  16ch total = 4ch EGT, 4ch cht, 1ch oil pressure, 1ch oil temp, 1ch fuel psi, 1ch fuel gph, 1ch manifold psi, 1ch air temp, 1ch humidty, 1ch air psi

  Code for proof of concept I tested http://www.hertaville.com/interfacing-an-spi-adc-mcp3008-chip-to-the-raspberry-pi-using-c.html
