Mijn eerste GR130

Small step for RC turbine, big step for me

EGT and RPM now reading and displaying correctly

 

I have also come this far. It is not easy

 

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?

 

Xicoy. magnet ring and rpm sensor.

 

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

 

only. RPM. PPM.and TEMPERATURE read.

 

I use these magnets: https://www.supermagnete.nl/eng/rin...sed-neodymium-n45-nickel-plated_R-10-07-03-DN .

 

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.

 

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

 

Looking good, Haldor.

 

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
