Which Mikuni ?

Looks very nice. I'll be making my own instruments based on cheap sensors, an Arduino microcontroller, and LCD displays. Here is a Wikipedia quote about Belite: "On 6 June 2019, the Belite facility was destroyed by fire. The company has since been unable to continue to operate." The company may still be for sale.

Looks excellent! Would you be willing to share a parts list and the Adruino code for those of us who are "coding challenged"?
Thanks

I have so many different sensors and Arduino models I have not decided how many instruments to have on my panel, and/or which sensors to use. To that end, I have not made anything in final form or saved any code except some copies of Robojax code from his YouTube videos. I think I will make two instrument panels, one removable. I think I will try and fit a tach, voltmeter, turn & bank, ignition switches (I'm rigging/making my own ignition), CHT, EGT, oil pressure, oil temperature, Hobbs meter, and angle of attack display on the permanent panel. On the removable I'll probably have compass heading, altitude, airspeed, air temperature, time, voltmeter, a holder for my handheld Yaesu COM radio, and a holder for an i-Pad (moving map display). I plan to have two Lithium-Ion batteries. A 12.5V for the permanent panel and ignition, and an 8.4V for the removable panel since the Arduinos don't need 12 volts to operate. I made a little generator to charge the 12.5V pack using a small propeller on an RC airplane brushless motor feeding a rectifier and voltage regulator. I'm a long way from completing any of this in final form, so you will probably be ahead of me in design and execution.

Wow! This is all great stuff. I can’t wait get some components and start seeing if I can make it all work. Engine information and ignition would be spectacular. In the interest of flying as soon as possible, will probably start out with the magneto. I think they can be altered to get a full 28 degree spread. Magnetos just seem to be archaic compared to today’s EI systems, just don’t know how to build one. Definitely want 0 degree or even a degree or two after TDC for starting then I think 28 there abouts for Normal running. Not sure if it needs a curve. Thought I struck gold with the 123 EI system used as a replacement on a Citroen. Bluetooth to your phone to make custom ignition curve. Problem is they run off the camshaft not the crank which is what I have access to, and I think in the opposite direction. The tech in Europe didn’t seem too interested in talking about it. Maybe with your help we can build our own.
Thanks

Hi 914 Pete
Were you asking about my temporary mount? It’s a mount that I got with the Mosler engine. Came off a n3 pup I believe, fits engine but not the front of the eagle. I’m in the process of altering it to fit my plane. Basically just using the actual shock mount parts with all new heavier walled tubing. Rigged it onto the plane just to hang the plane to balance it, so I would know how the new mount should be built.

Been working on a similar project building an CHT/EGT Arduino monitor app.

Made some progress but going into a Alpha 2 stage - had some initial issues with my design PCB.


Way want to check this out - something I have been looking at for attitional instrumentation.
