Update on my custom digital speedo for my bike...
Also known as the Digital Dash project
So I put this mockup dash together to test out the new gauge stepper motors and start building code thats more towards the final project.
This currently doesn't have the LED lights that will run up the side of the dials and light up along with the dials.
I spent several days trying to get the x25 library to work on my maple mini. I had to make some minor changes to the library, changing a variable type, changing stepper pattern pulses...
I have random values being generated for most of the gauge displays, they all move rather erratically at the moment. I might do some work on the random code to give a smoother flow of data...
Apart from that its nearly time to start making sensors to real real RPM and MPH data and start making real code to calculate it...
Currently this is all running off one 75Mhz maple mini. Im looking into ways of doing threading to smooth out the motor updates. I might still split up the project over several arduino mini boards that have there own dedicated tasks...

Hi guys sorry for the lack of update... Ive been busy with electronics trying to work things out...
The circuit design has been tweaked a lot... Im still using 2 vRegs for the running and high beam light signal but only because they could run for a long time and I felt would be suited better for the long running than resistors... though that could change after some further testing...
Im about to print out my first PCB of the dash, but I just have one last thing to sort out.
I need a little help or some input on how the Fuel Gauge works on this or tbh any other bike... If there is a standard way.
For the most part I think I've worked it out, but it was a little confusing as the Wireing Diagram for the bike is, while correct is slightly different to when the dash comes involved.
After taking the dash apart and looking at the fuel gauge to work out how it worked, I was a little surprised. Not as I expected.
On the wiring diagram both the yellow and blue wires go into the gauge and feed to the sensor. I expected one wire took the 12v off the black wire and went through the float resistor. And the gauge read the returned voltage off the other wire.
However on taking the gauge apart I realised the bluewire wasnt even connected to anything... it stops at the loom socket.
And I think the gauge reads through a voltage divider.
This is what I want to confirm, before I accidentally send 12+v down into a float resistor thats designed for a lower voltage and makes my tank explode
Excuse the symbol for the floats variable resistor. I know its wrong but its the one used in eagle...
Does anyone know;
Is the float resistor a 10k or 100k? Im thinking 100, but I cant test it right now...
The returned voltage on the divider ranges between 7 and 12 volts, assuming the in volt is a clean 12 (which it isn't), Dont worry ill be dropping this to a voltage the project can read safely...
Does that sound right? Tbh I exspected between 0 and 12 before I opened up the dash and saw the 75ohm resistor...
If anyone can confirm any of this for me... or stop me from killing myself in a painful fiery way, I would really appreciate it.
PS sorry for the slightly hard to read post, im really really tired after being ill most of last night... Was kinda hard to explain everything ____________________ Yamaha FZ8/Fazer800 (split headlight one) 2014, gingerly getting used to the massive increase in HP and not killing myself in the process!
