Selfmade speedometer

[Axel]

Hi Mike,

It´s very interesting. I just started to read a bit about Bluetooth modules from microchip. The cost start with about 6,- USD and should easily be implemented with their software stack (whatever "easily" mean...). An Arduino solution might be a bit easier as they have "ready to fly" software for different applications available. I don´t know yet.

Could you keep me inform? Thanks!

All the best!

Love to see this come to be. I would even be willing to add a small LED bank under the phone for Turn/Neutral etc. Just be happy to have a tach and speedo.

I dont really have an issue seeing my phone on the handle bars

Hm, and a bluetooth module allow to control other functions at the bike like starting the bike while sitting outside of the beer bar or just play with the turn signals. However, it might result in problems to use a phone for these functions, but it´s possible, just an idea...

Could be a big problem if your bike was in gear and you try to start it. Maybe only start while bikes in neutral.
But why is it a need?

Hi Rick,

Yes, I agree. Using a phone for starting is just a gadget and absolutely not a must have and could be dangerous. I have a friend (and competitor...) who makes a control box with a bluetooth adapter: http://shop.motofreakz.de/Elektrik-Instrumente/Steuerboxen-Zubehoer:::1124_1010.html (only in German language). I´ll ask him how he had solved it. I think they check the neutral input.

All the best!

Hi,

just an update about my new toy: I have separated the controller board and the display, what will clean the harness a bit, cause only 4 cables need to be wired to the display. The rest is somewhere under the tank. Here is a small video (sorry, again German language...):

I still have the challenge that the 49440 pulses per mile work fine at lower speeds until about 50 km/h but result to higher failure rates when the bike speed is higher due to the asynchron work of the microcontroller and the resolution of one pulse per 3,3 cm. However, it works fine with an external wheel sensor. I have add a software trigger function in the menue what allow to use all kind of sensors, regardless if they produce plus or minus pulses. I still need to program the option 1 spark per turn <-> 2 sparks per turn in the config menue what allow to use it in different bikes.

I´ll give one speedo prototype to a friend next weekend. He just convert an old Moto Guzzi to a cafe racer and he will test it in this bike. I hope to find the time to put one device in my Ridgeback until the season starts. I haven´t found a good position yet and even don´t know if I get the lcd waterproof. I´ll keep you inform...

All the best!

Looks cool! Just a suggestion throw a volt meter option in there too? Maybe make the skulls eyes light up if it drops below 12.5 or exceeds 14v? Just a suggestion.

Or an option in the settings to have it some where in your home screen if you want the voltage displayed all the time while riding woukd be cool to have both.

Good luck with it! If ya could make the LCD round and fit in the stock housing I would buy one for sure. Interesting about over 50 mph. Gotta be a trick to that since Dakota Digital had to have figured it out.

That's the best damn idea you ever posted had to say it

Not as dumb as I look eh?

Hi Eric,

Great Idea ! I´ll take care of it for my next prototype. It´s not complicated anyway. Thanks !

All the best!

Yep figured it was just some quick programming! You are welcome, that will cost you 2 cents..haha

Thanks for sharing your project.

... I got one more suggestion today: The high beam indicator is the skull with blue sunglasses instead of the "HIGH" text. I´ll keep you inform

All the best!

I still want it to work with my phone!!

 

[Jwooky]

Any progress on this @Axel ?

 

[Axel]

Yes, I think it´s ready and there are still a few devices out for testing. Just feel free to look at:

It is a streetfighter design from a client. He made it in one weekend include learning how to handle the editor software. However, I hang a bit with the documantation due to other work here. The docu is unfortunally important to sell this product, but I prefer to sit on my Ridgeback at this weather. The funny things like programming and making the hardware are done but documentation is not my thing...

All the best!

[cdogg556]

Really cool Axel, but can you make it round to fit in our housings?

 

[Jwooky]

I volunteer to help develop one

 

[Th3InfamousI]

Hopefully it has more than one trip meter. Personally I don't know Why Dakota Digital stopped at 2. Should be 3 minimum but really user preference 1-5 or something.

Personally I would like to have
1 -Trip for Gas
1 - Trip for Daily mileage
1 - Trip for overall actual Trip mileage

Everytime I go on a multi-day trip I always end up wondering how many miles I did that day I can do the math but it just be easier to have a dedicated one. I typically reset my B Trip at the beginning to log total miles on a trip but by like day 3 or 4 it gets harder to remember who it was the prior day so I just ballpark it

Another one could be used for maintenance or something as well you reset at oil changes.

Axel, perhaps you can help me with a problem I'm having: I recently installed a new Medallion Speedo, but have no way as of yet to set the odometer to the correct mileage. It would seem that you have a way to manually increment the mileage with your controller; is that true? If so, that might be the only way I can set the mileage and I can get back on and ride.

Axel,
What are the dimensions of the screen you are using? I would like to try and help with a housing. and create one as well. I have 2 ideas when it comes to the housing as far as making it round or oblong.

Hi Bryan and John,

Sorry for the late reply. I was a bit busy with other things and simply had not looked in this forum since a few weeks :-(

Bryan, just feel free to look at https://www.healtech-electronics.com/products/sh/ These guys build a speedo adjustment device beside of other nice products. This part will help you to adjust your speedo to the correct value. I think, that Thunder Heart had a similar product, but I haven´t found it on their web page.

However, I still have the same problem with my speedo, what can handle a minimum wheel diameter of 3 cm, what is still too much for the Big dog sensor, due to the 44000 pulses per mile what gives a smaller resulution. So, my next toy will be a similar device of the "Speedo healer", what convert the BD pulses to my speedo within the next wintertime, when my 2 Bluetooth toys are ready.

John, I use the Nextion 2,4 - 3,2 " displays. You can download the datasheets with the necessary dimensions from https://www.itead.cc/wiki/Nextion_HMI_Solution. Just gsend me a mail, if you are not successful with the download.

All the best!
