Your project is very impressive . The simple is always better, but I'm not giving up yet.
I am temporarily away from home, no possibility of steel-working, and the Arduino project is also a challenge for me.
Now I will refitting the speedometer to bike and continue to experiment.

The next step is to enter the Hall effect sensor signal into the Arduino. I made a model. The ABS ring rotor is replaced by a fan blade and three neodymium magnets. https://picasaweb.google.com/lh/photo/k_swDcVqv816xIESloTZktMTjNZETYmyPJy0liipFm0?feat=directlink https://picasaweb.google.com/lh/photo...

exactly, it is a low pass filter.

The voltage divider does not work. The voltage can be set but the instrument still to show zero. I tried a low voltage power amplifier LM386N https://picasaweb.google.com/lh/photo/t0foZvBPj-JapL29vZLV4tMTjNZETYmyPJy0liipFm0?feat=directlink This works properly but change the square wave. https://pica...

Yes the connector and rings and two Hall effect sensors still present. I like Your impressive project, but I wish keep the opportunity of reversebility. At first must drive the speedo, I'll looking for a signalgenerator which is a controlled ampitude.

many thanks for your helpful assistance

Hi Sweatmark. Yes it is. But unfortunately the iABS unit was missed when I bought the bike. The Abs harness at first sight, original untouched. However, I don't know what to do 4P-OUT pin at upper right corner next to the GND?? This would be the speed signal grund? The Arduino output look like to co...

Hi there! I has bought a Rockster without iABS unit. I would solve the speedometer signal conversion with Ardunio board. I was dismantled the speedo and tried drive with 100Hz TTL square wave signal. The experiment is resultless.. :( pins: IGN = GR BR +12V GND = BR + BL R Ground 4P OUT = BL GR ??? S...
