    Small step for RC turbine, big step for me :)

    EGT and RPM now reading and displaying correctly :D

    I am struggling, pulling hairs but also having fun :)

    Do you have any input on a good hall sensor to use / magnet part number?
    I am using a generic U1881 hall sensor and some small magnets for testing purposes (2x2mm) but this configuration is not powerful enough to detect RPM from <30mm distance the turbine will require.

    BTW - my RPM circuit with hall sensor, will it be able to read 6-digit RPM values?

    Thank you, hopefully the magnets will arrive soon.
    What functions have you been able to incorporate into your ECU? Streaming data and/or functions?

    Thank you very much!
    Sent you an email Ray :)

    ECU Monitor prototype one solid step furter :). Step 1 complete.
    Next step in this department is to emulate a servo and let it drive the PWR value and govern voltage for the fuel pump :)

    Why emulate a servo?

    To make a ground station to operate the turbine, without a radio ;)
    At the moment I don't have one as I sold my MC24 off a few years back. :rulez:

    Why not build a stand alone / test fuction in the ECU? :)

    Hehe, certainly possible and I haven't carved anything in stone yet :). I am waiting for Mosfets to drive a fuel pump, just got to make the pump first :hammer:

    Minor update, no pictures yet.

    The stainless steel needles arrived (5pcs 180mm long) so now I switch drive from software to hardware :)
    Next up will be learning how to braze brass/steel together! The evaporator sticks are cut to length and I need to form their flanges prior to spot welding these to the CC ring. Hopefully the CC and fuel delivery system will be completed this week :D

    First time for everything, finally found some time to braze the brass tubing and fuel sticks :)
    Went alright, just needed to apply enough heat and allow the heat to soak properly. Used a MAP-torch for the job.

    One of the 6 sticks is a little weaker (the "middle one " in the first pic) than the others, might redo that one.
