No, the prototype is based on the Ardunio UNO, breadboard and individual sensorboard for the temp.sensor. The key component there is the Atmel chip (Processor), MAX6675 chip (temp) and hall sensor (RPM). Space/component wise a really condensed version can be made, and certainly lightweight (<50g)
For monitor purposes only only the sensors are needed to be installed on the turbine, with external connection to LCD for displaying the data.
This excersise isnt costwise worth it, a ready2go commercial ECU can be had for aaround $120 and up. Like building the turbine, I am in it for the challenge
