2006 Vulcan Nomad Custom Speedometer Instrument Bezel

thingiverse

My 2006 Kawasaki Vulcan Nomad's instrument cluster started going bad, cant see the display due to sun damage. I chose to put in an all digital unit. This is my project. Theres some incompatibilities between the vulcan and the new display unit, like speed sensor and gas guage sensor.. so im putting in a cpu to do the compensations. Adafruit CPU converting signals between vulcan and instrument. https://www.youtube.com/watch?v=XnBeBRjZbtk - Note: - the tiny m0 processor was just for testing until the M4 arrived. https://www.amazon.com/gp/product/B07T3DBR8V/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 this has the CPU power to handle upto 10K rpm and the number of pusles it can handle. the m0 cannot --- debug of app https://www.youtube.com/watch?v=jCGiD1r49s8 testing signals to device for mph https://www.youtube.com/watch?v=gKRbxlfor3M Test RPM https://www.youtube.com/watch?v=Y-TD5PEV38s Test Fuel https://www.youtube.com/watch?v=XwbjftRY-qc Frequency divider for speedometer. have to reduce pulses from vulcan to this new display. https://youtu.be/pp9RYTo79FE 8-5-220 Just got back the custom circuit boards from HongKong. used this company, and very please with the cost and results. they charged me $2 for 5 of these boards (minimum order). I added the pictures of the board, its double sided, just soldering in the parts now... https://jlcpcb.com/ **** this is a work in progress, many things are subject to change... i posted to show progress and the overall idea of this project *** once complete, ill update the cct boards, designs, etc. **** 8/7/2020 - testing the assembled circuit on my workbench...I had to remove the input caps on the speedometer op-amps, they were filtering out the signal too much. 8/15/2020 - uploaded latest Python script for the processor. still need to test also on the cct board i removed the input caps to the opamps for the speedometer,tach and also the diode on the tac input. so C3, C4, C9, C10, D1
